Replacing the UAZ Patriot engine with an imported one. UAZ "Patriot": real fuel consumption. UAZ "Patriot": characteristics, reviews An example of tuning a motor

The Patriot SUV is the flagship of the well-known Russian UAZ brand. Serial production of the car began in the summer of 2005, after its predecessor, UAZ "Simbir" (1997-2004), was discontinued. Base Gas engine UAZ Patriot - .10, just like the diesel ZMZ 514.32, went to the car from its predecessor.

In addition, for several years (2008-2012) the Ulyanovsk Automobile Plant (UMP) produced the original version of the Patriot model, equipped with Italian diesel engine IVECO F1A, which many experts consider to be optimal for this car.

INTERESTING! Currently, ZMZ (JSC Zavolzhsky Motor Plant) is completing the development of a new 2-liter car engine with a capacity of 140-150 liters. with. (torque 300 Nm).

In addition, it is planned to produce a more powerful power unit equipped with a turbocharger. The new engine will fully comply with the mandatory international Euro-5 standards.

Description

The power unit IVECO F1A is an example of the family of commercial engines of the international corporation Iveco.

The engine is designed for installation in small cars. Like all commercial motors, it has a large service life and a high degree of maintainability. These results are achieved by increasing the weight and height of the motor.

Structurally, it is an in-line 4-cylinder diesel engine designed as a "sandwich". It is equipped with a fuel supply system of the type Common rail(microprocessor controlled forced fuel injection) with common rail and turbocharged with intercooling and exhaust gas recirculation.

The engine block has a thicker wall and is made of ductile iron. In its lower part, the crankshaft main bearing caps are fixed, structurally combined into one strong supporting part (crankshaft bed). An oil pan made of steel is attached to this part. This type of bed plate design provides the entire engine with increased rigidity, which is important for commercial vehicles on which this power unit is installed. Their weight can reach 6 tons.
Of particular interest is the original design of the cylinder head (cylinder head). It differs from conventional ones in that the camshafts of the gas distribution mechanism (timing) are assembled in a separate housing, which is installed on top of the cylinder head. This design led to an increase in the height of the motor, but made it possible to quickly replace the camshafts in case of wear (without disassembling the timing).
The intake camshaft is driven by a toothed belt with an automatic tensioning system. The exhaust camshaft is driven by a chain that connects it to the intake shaft. Both camshafts have three bearings and are tunnel-mounted.

Maintenance

One of the advantages of commercial engines is their unpretentiousness and simplicity. Maintenance. The engine does not require adjustment of the timing valve clearances, as it is equipped with special hydraulic compensators.

An engine oil change is required after every 20,000 km, and air filter change no earlier than 80 thousand km of the distance traveled. Interestingly, in Italian-made cars, it is recommended to change the engine oil no earlier than 40,000 km. At the same time, the volume of the poured oil was increased to 7 liters.

Answering the question: "What kind of oil to fill in the engine?", Iveco engineers recommend using Urania Daily and Urania LD 5. According to domestic experts, it is also possible to use engine oils specifications SAE 15W40 or SAE 5W30.

Tuning

There are many options for tuning the UAZ Patriot IVECO F1A engine. With their help you can:

increase engine power;
increase the amount of torque;
reduce fuel consumption, etc.

Among the numerous types of tuning of the IVECO F1A power unit, UAZ Patriot owners most often choose:

Chip tuning of the UAZ Patriot engine via the OBD2 diagnostic connector

The IVECO F1A motor is controlled by an electronic control unit (ECU) of the BOSH concern, assembled on the basis of a Motorola processor. To connect to it, use the most secure full access mode. For this, a BDM interface is used, which is specially designed for rebooting and debugging Motorola processors.

As a result of software update and high-quality debugging, the following results are obtained: increase in power and torque value by 20 ... 25%; the ability to programmatically or physically disable the EGR valve - recommended for vehicles with high mileage.

Tuning the UAZ Patriot engine without interfering with the work of the standard software.

Tuning the UAZ Patriot engine using Rambach technology, unlike other methods that involve replacing the engine control algorithm, does not affect any of the factory settings, but only corrects or complements their work as an external device.

An external POWERBOX electronic unit is connected between the sensors that control the operation of the power unit and the ECU. In the course of operation, this unit, receiving signals outgoing from the sensors, corrects them and then transmits them to the control unit. In accordance with the received signals, the standard vehicle ECU corrects the operation of the motor, improving its performance.

Installation of the POWERBOX unit allows you to: increase power and torque by 30%; reduce fuel consumption by 12%; to adapt the operation of the fuel supply system to the quality of domestic diesel fuel.

Upset the reverie of the car when you press the gas pedal? Missing an engine? Disappointing overclocking? Is there something behind the car? Twitching the car when shifting gears? Lacking driving comfort? Do you want a smaller expense?

There is an effective solution for you. This decision is not to drive! It is for those who want to feel confident behind the wheel and enjoy driving.

The car is driven by the engine speed and by the torque of the torque. We make it so that increases torque increasing low-speed traction... Due to this, for example, acceleration dynamics increases, reverie disappears or such an effect when the engine roars and the car does not move. All pluses are further in the text.

Hello!

Tenth year doing what mechanically I remove gaps, dullness from cars. Including on UAZ Patriot increasing power in the range from 1000 to 3000 engine revolutions mechanically... How the process of mechanical revision takes place can be seen in the video.

First, the client tells how his car is driving and why he decided to seek help. Then the very process of mechanical revision. And finally, the first changes in the car that the client noticed.

* The service is one-time, for the entire life of the vehicle. No engine intervention and electronics... No loss of warranty. We give a guarantee for our service.

The result of our work is expressed in the following:

lower consumption for the same mileage
cars are more powerful at low revs
improved acceleration dynamics
dips disappear when accelerating
the thoughtfulness of the gas pedal goes away
the car follows the gas pedal
the character of the car is changing
maneuverability appears
you manage to overtake

great driving experience

A short video about the results using the example of UAZ Patriot 2015:

On one UAZ Patriot of 2015, the consumption from 15-17 in the urban cycle fell to 12 liters - this is 20-30% savings. If the spouse drives, then the flow rate on the device shows 10 liters per hundred.

By license and based on western technology we are changing the physics of the air flow.

* Changes in air characteristics cannot adversely affect the engine in any way.... But on the other hand, it perfectly increases engine power at low and medium speeds and reduces fuel consumption. And all this without interfering with the engine and electronics (ECU).

You are now on the introductory page. A full-fledged site is located at www.as007.ru ( AutoSila007) *. Here information is collected from the pages of the site in a single logical sequence, and will give you an idea of our offer.

Our technology allows better mixing of gasoline and air vapors. Chip tuning can't do this!

Drops of gasoline do not burn, but are thrown into exhaust pipe... This is about 25-30% in science. And this is 250-300 rubles. from every thousand spent on gasoline. Our refinement increases the compression and drops of gasoline go into a state of steam. As a result, the fuel burns more completely. That's why our revision pays off.

If you are frustrated with fuel consumption or lack of power, we address this disadvantage: quickly, safely and affordably, without increasing fuel consumption. Call us now!

* The service is reversible... Time is given to "touch" and a money-back guarantee if you don't like it.

Despite this, the UAZ “Patriot” produced at its facilities is fundamentally different: the SUV turned out to be more “domesticated” and adapted to everyday life.

Characteristics of UAZ "Patriot": fuel consumption, power, speed

After several modifications, the main components and assemblies of the car did not undergo any changes, remaining at the same level: the SUV is equipped with a four-cylinder petrol power unit with a capacity of 128 Horse power, with a volume of 2.7 liters. Fuel is supplied by injection type, the whole system is based on fuel injection directly into the cylinders and complies with Euro-2 standards.

Also available are models with a four-cylinder diesel engine with a capacity of 113 horsepower and a volume of 2.23 liters, an injection fuel injection system. Somewhat earlier, engines of not only domestic production, but also Italian ones, which had 116 horsepower and 2.3 liters of volume, were installed on the UAZ. However, such engines were not installed on the Patriots of 2015 and later.

The vehicle has a standard transmission - mechanical five-speed gearbox gear. Four-wheel drive, and the front one is manually connected by the driver.

Fuel consumption

Happy owners of a brand new crossover of domestic production almost immediately after its acquisition are faced with a not very pleasant problem, which calls into question the feasibility and rationality of this purchase as a whole. The point is that the fuel consumption of the UAZ "Patriot" with a full tank exceeds all conceivable values and does not correspond to the declared by the manufacturer, while the fuel level indicator can show almost complete absence of gasoline after a hundred or two kilometers.

Simple calculations made by the owner of the car indicate in this case that the consumption exceeds 20 liters per 100 kilometers, after which thrift comes into play, because of which it remains only to regret that the model was not taken from diesel engine... In fact, everything is not as deplorable as it seems at first glance. If we calculate the total amount of fuel spent on several thousand kilometers, then real expense fuel UAZ "Patriot" will be about 11-13 liters.

Reasons for the discrepancy

Such a clear difference in indicators is directly related to design features car. The fuel consumption of the UAZ "Patriot" depends largely on the fact that it has two fuel tanks: the main one is used for refueling, and the auxiliary one is filled from the first with the help of a built-in jet pump. It works very slowly, so the process of filling both containers takes at least 15-30 minutes. During the start of the movement, gasoline from the auxiliary tank enters the main tank; when stopping, everything happens in the reverse order.

Instrument panel gauge readings

The fuel consumption of the UAZ Patriot may be incorrect due to one more reason. The sensors installed in the tanks show a non-linear change in the fuel, since the tanks themselves are straight. The devices themselves are VAZ, they were created specifically for the "Lada", the tanks of which are of a slightly different shape and taper upward, expanding downward. Accordingly, in the upper part, the level of gasoline in them changes several times more slowly.

In UAZ, on the contrary, the gasoline level drops linearly, and this happens several times faster. Accordingly, the sensors will not show the actual fuel consumption for the UAZ Patriot. Gasoline, even if it is quickly wasted at the very beginning of the journey, will actually be saved.

Distortion of data by the on-board computer

The reason for this lies in the fact that initially the device itself is not subjected to any calibration. The opening time of the injectors enters the ECU, and from this information it calculates the fuel consumption. Actually, this is the reason: depending on the model of the injection system, the performance of the injectors also changes. In order for the computer to give real information, it is necessary to calibrate it. It will be most accurate on full tanks, however, it can be done at idle speed.

In this case, the fuel consumption of the UAZ "Patriot" is regulated as 1.5 liters / hour, while the computer outputs a figure of 2.2 liters. The average is correct. It is advisable to connect a calibrated BC of a similar car model before starting measurements, while changing the mileage calibration.

Car tire pressure

Fuel consumption largely depends on the level of pumping of the wheels, especially the rear ones. It is advisable to regularly check the tire pressure: the front should be slightly less. In addition, fuel consumption may increase due to operating front axle hubs. The gearbox of the front axle at negative ambient temperatures is blown by a flow of cold air and rotates without a special load, which will lead to the creation of additional resistance between the unheated and non-liquefied oil. To avoid this problem, it is advisable to use only a high quality synthetic lubricant, the viscosity of which will not change at low temperatures.

In addition, you can save fuel with regular use of the car by driving in high gears, constantly monitoring the number of revolutions. Care must be taken that they do not fall below the minimum mark of 1500 rpm.

What is the fuel consumption of UAZ "Patriot" in reality

Considering all of the above, we can conclude that not everything is as sad as it seems at first glance. For UAZ "Patriot" fuel consumption (reviews of numerous owners this car this is confirmed) is about 13.5 liters per hundred kilometers within the city limits. Most drivers note that when driving on the highway, consumption is about 10 liters per hundred kilometers. With an increase in the speed of movement, it can increase to a maximum of 11.5 liters.

For the diesel version of the "Patriot" when driving on a country road, the consumption will be about 9.5 liters. In urban areas, it changes to 12-13 liters. The turbo diesel engine will consume about 15 liters off-road. Consumption may increase accordingly when using an air conditioner, all-wheel drive, stove or with flat tires.

Despite all the advantages of the diesel "Patriot", they acquire it, according to statistics, only in 5% of cases. The main deterrent factors are the high cost, the impossibility of transferring the car to gas and the difficult maintenance of the engine. In addition, it is also repelled by the high noise level and the almost complete absence of sound insulation.

Two humps are only good for a desert ship. But an SUV is not a camel, a double-humped torque curve for its engine is not the best option. That is why I shuddered when my good friend Volodya Sharandin invited me to drive the Patriot along the ice track.

We passed, we know! To drive, when after the first burst the thrust drops to three thousand revolutions? Dubious pleasure. Even the next surge in the region of four thousand does not help. Yes, and high-speed exercises on the Ulyanovsk all-terrain vehicle seemed to me akin to off-roading on a passenger puzoterka.

But Volodya knows how to persuade and, frankly, never proposed stupid ideas. Moreover, he had not been to his homeland for fifteen years, and during this time he became a cool automotive engineer, complementing his Russian education with American and European. Today his strong point is civilized tuning in its own center. In general, I was intrigued: UAZ in its performance should be extraordinary.

Gave traction

The door slammed and I was driving the Patriot. Everything is familiar, only the engine sounds strange. Not louder, but the tonality has changed, and for the better. I like this song better than the old one. How about on the go?

Here the moment is two hundred and seventy and the power is one hundred and eighty. Don't be shy, spin until you cut it off!

Sharandin teases, but you don't have to ask me for a long time. Gas to the floor! I didn’t drive such a Patriot - it accelerates very quickly! It became even scary: you have to get used to the brisk character, because the chassis and brakes are standard, but the agility is different. Vnatyag? And at the bottom, this Patriot is more convincing. Lucky exactly, without plugs. Especially after 1800 rpm.

A surprise awaits me on the track - standard Patriot... Volodya provided for this "piano in the bushes" so that I could change from car to car - for comparison. Well, go ahead!

First, a small motocross piece. You can't accelerate here: continuous hills with steep descents and ascents. Serial Patriot took all the slides - some in first gear, some in second. And in a car with a modified engine, you can drive differently: after a couple of climbs, I stop switching - there is enough traction, I go through the entire obstacle course in second gear.

The highlight of the program is the autocross track. Turning corners and appendixes, ice interspersed with snow porridge. The serial Patriot, with its weight and overall height, handles well on slippery roads. Of course, we have to be active. I twist it at large angles - tea, the mechanism is not rack and pinion. In areas with loose snow, so as not to lose speed, I switch from third gear to second. I switch often, but in general - bearable. To be honest, after this "race" I changed my opinion about the Patriot for the better, but did not get much pleasure. Still, a serial UAZ is not for drifts and drifts, storming turns with a fan is not his element.

Now - 182-strong car. Truly, there is never too much power and moment! The chassis is the same, but the ride is more pleasant and, most importantly, safer. Almost the entire track is in third gear, switching only in a couple of places. Now I understand why Sharandin invited him exactly: this Patriot is already controlled by gas - and you get pleasure from the process. Instead of oiling the steering wheel, you can actively use traction - the engine, one might say, pulls the Patriot out of the demolition.

Arrived in our shelf

At the base where Volodya is finalizing the cars, homework is already in store.

Look, we managed to smooth out the humps, and not just raise the torque!

Sharandin posts a printout of the external speed characteristics of the motor, taken on the MAHA roller stand. Indeed, an almost flat shelf of 260–270 Nm in the range of 1800–4800 rpm. And the power is much higher: 182 hp. at 5200 rpm. The serial engine produces 134 hp, and the maximum 217 Newton meters - the same humps at 2500 and 4000 rpm. The most curious thing is that such results were achieved without opening the engine and, accordingly, without installing new shafts, pistons, connecting rods. Changed only inlet and.

Direct flow? Whom will you surprise with this! Everything is much more interesting than the primitive struggle against backpressure - here the intake and exhaust are coordinated.

Shelf alignment technology is as follows. First, a 3D scan of the engine compartment and the underside of the car. This allows you to evaluate the space in which new parts are to be placed. Then comes the calculation and design of iron.

The task is to boost the engine by improving the filling of the cylinders. To do this, work with air flows at the inlet and outlet and harmonize the wave processes in the engine.

Then an exhaust manifold is made with pipes of equal length. The "spider" of the 4-2-1 scheme fit into the UAZ (the 4-1 variant cannot be placed in the engine compartment). That is, the pipes are first merged in pairs, and then they go into a single pipe. Next comes the modified resonator and muffler. Everything is stainless steel.

And also - a non-standard intake. The low resistance filter is placed in a cold zone where the air density is higher. Behind it is a diffuser and an intake pipe. Their diameters, roundings, dimensions are the result of calculations and experiments. After all, the air flow does not like a sharp change in direction, sharp contractions and expansions.

After assembling the components on the car, the fine-tuning procedure begins on the MAHA roller stand. The wheels are scored and the electronics plotted power and torque curves. In the initial version, telescopic pipes are used - by changing their length, the developer adjusts the characteristics. Volodya, although he is a racing driver in the past, prefers not to bet on high revs, and at the moment - such motors in daily use much more convenient. The Patriot is a very special case: improvements should not affect his all-terrain qualities. To lose traction at low revs is to ditch.

If it is possible to get a weighty additive due to "inhalation-exhalation", that is, inlet and outlet, why does the plant not do this?

Features of mass production do not imply individual selection of engine characteristics and work on "gold" technologies. There the average setting rules the ball. "Eternal" stainless steel release, playing with telescopic collector pipes, rejection of a filter box in favor of a filter of low resistance is the lot of small tuning firms. And they kill several birds with one stone.

Moderate forcing does not affect. In this regard, working with a hitch is a much less risky business than disassembling the engine with the replacement of expensive parts. And, which is very pleasant, the price is not exorbitant. The modified intake-exhaust system costs about 50 thousand rubles - taking into account the installation and settings.

Motor for 469 models

Engines for UAZ 31514 are available in several versions. By type of fuel, they are divided into gasoline and diesel. Many characteristics of the car, including fuel consumption, depend on what engines are installed on the UAZ.

For example, a UAZ gasoline engine of the ICE 210.10 type with a volume of 2.4 liters has the following characteristics: power - 91 liters. with., fuel consumption - almost 12 liters per 100 km. In UMP 4178.10 engines of the same volume, there are already 87 horses and fuel consumption increases by one and a half liters.

General characteristics of engines

The main suppliers of engines for UAZs are the Ulyanovsk Motor Plant and the Zavolzhsky Motor Plant. UMP became famous for being practically the only manufacturer of engines for off-road vehicles in Russia. All modern engines produced from the assembly line of the plant meet Euro-4 standards.

ZMZ produces more than 80 different modifications of engines ranging from 2.2 to 4.6 liters. The units of this plant are installed both on small off-road vehicles and on buses of domestic and foreign companies.

There are other types of engines that are installed on UAZ 31514 vehicles:

UMP 4218.10 with a volume of 2.8 liters (gasoline);
ZMZ 410.10 with a volume of 2.9 liters (gasoline);
UMP 420 with a volume of 2.4 liters (gasoline);
ZMZ 514 with a volume of 2.2 liters (diesel);
Andoria 4CT90 with a volume of 2.4 liters (diesel).

The Andoria engine installed on UAZ 31514, Iveco and UAZ Patriot vehicles is produced not in Russia, but in Poland. These engines are in demand not only at the Ulyanovsk Automobile Plant. They are also installed on other Russian-made machines.

Base motor UMZ 421.10 for UAZ

The base engine UMZ 421.10 with a carburetor system, having a volume of 2.9 liters, runs on gasoline. Has a gas exhaust system. It can operate at temperatures from -50 to +50 degrees Celsius. The 4218.10 unit became a modification of such a motor.

The main difference between the UMP 4218.10 is in the gas exhaust system, which is not tuned. This simplifies the installation of the engine on UAZ vehicles, even with a wagon-type body. Currently, motors of this series have several modifications.

UAZ 39626 and Patriot motors

The UAZ 39629 vehicle, in other words "sanitary", is most often used to transport patients and is available in most medical centers. It is widely used both in metropolitan areas and in rural areas. These machines are equipped with three different engines.

ZMZ-402.
UMZ-4178, similar in characteristics to the first, differ only in manufacturing plants. These motors have a displacement of 2.4 liters and a power of 92 horsepower.
UMP 4218 with a volume of 2.8 liters and 98 liters. with. under the hood.

UAZ Patriot cars are equipped with a four-cylinder four-stroke engine of the ZMZ 409.10 series. The valves are located at the top, and the cooling is liquid. The ignition system of this engine is microprocessor-based, fuel injection is distributed. The diesel engine ZMZ-51432 for the UAZ Patriot is a must.

Diesel fuel is more economical and practical

In Russia, diesel fuel is gradually becoming fashionable, but until recently the production of diesel engines was only in the plans. Foreign diesel engines for the UAZ Patriot, as a rule, did not fit, and attempts to aggregate them were abandoned.

Reviews of the UAZ Patriot diesel engine of the foreign company IVECO F1A end with negative reviews about its quality. Maybe because Ulyanovsk or Zavolzhsk motors are more common for Russian cars. The volume of the overseas engine is 2.3 liters, and the power is 116 horses. The Italian engine is noisier and less powerful. However, owners of a Patriot with a foreign engine will be pleased with good traction and fairly economical fuel consumption - a little less than 10 liters per 100 km.

Not so long ago, the Zavolzhsky Motor Plant began to produce an engine that runs on diesel fuel, for SUVs UAZ Patriot and UAZ Pickup. The ZMZ-51432 motor is small-displacement, its volume is 2.2 liters, it complies with the Euro-4 standard. The engine has a maximum power of 114 horsepower, 3500 rpm and low fuel consumption.

There are many original parts in the motor, thanks to which energy and economic indicators have increased. At the same time, emissions of harmful substances have been reduced: by half in comparison with engines corresponding to "Euro-3". The noise level has decreased in accordance with the requirements of the standard.

Characteristics of the UAZ 469 motor

UAZ 469 has a 4-cylinder engine of the UMZ 417 series with a volume of 2.5 liters. The power of such a motor reaches 75 horses, the location of the valves is upper. The fuel supply system is forced. Closed cooling system, liquid with forced circulation. The nuance of this engine is a fairly decent fuel consumption, up to 16 liters per hundred.

Two different modifications of this engine are installed on the UAZ 469 for two different purposes. UMP 4178 - for ordinary civilian models, UMP 4179 - for military ones. The difference between "military" motors is that they are equipped with a sensor-distributor and high-voltage shielded wiring. In addition, they have a special place for heating.

A distinctive feature of the UMZ 417 series engine is the special design of the combined cylinder block and the upper part of the crankcase into a single whole, made of high-strength aluminum alloy. The cylinders are wet removable liners and are cast in gray iron. The wear resistance of the liner is ensured by the acid-resistant cast iron at the top.

Aluminum cylinder head assembly for the UMZ 417 engine

The head of the block is common to all cylinders and is made of aluminum alloy, just like the pistons. The five-point crankshaft is made of magnesium cast iron.

Hunter engine features

The UAZ Hunter, which replaced the UAZ 469 in 2003, is equipped with both a gasoline and a diesel engine. The differences between a gasoline engine and a diesel engine for Hunter are insignificant.

The basic power unit for this car was a four-cylinder ZMZ 409.10 with a volume of 2.7 liters. The engine is equipped with a 16-valve mechanism and multipoint fuel injection. The power of the unit reaches 128 horsepower. The engine's appetite is up to 13 liters per 100 km.

The diesel engine for the Hunter brand ZMZ 5143.20 has four cylinders arranged in a row. The volume of the engine is 2.2 liters, there is a fuel injection system. In terms of diesel economy, the engine is largely superior to its gasoline counterpart. It requires a maximum of 10 liters per 1000 kilometers. But the dynamics suffers slightly, diesel in this regard is slightly inferior to gasoline.

The reliability of the engines on the UAZ Hunter car is the highest. The main thing, as the developers convince, is the correct care and timely repair of the failed parts. The motors show themselves well in off-road conditions in terms of traction development and are not capricious in the harsh Russian winters.

An example of tuning a motor

Tuning engines installed on UAZ vehicles is not so easy to do. Any tampering with the motor can lead to a decrease in traction force. And the models of many engines are outdated, so too many innovations and changes can play a cruel joke with them.

Certain mechanisms and systems can be modernized, of course. Changes to the piston group must be carried out with care and in accordance with the instructions. Piston rings change to forged, better quality and durable. The well-known company "Goetze" produces just such rings. If desired, you can install other details, but the work will require a professional approach and the appropriate tool.

It is possible to balance the UAZ 31514 crankshaft at home only with a flywheel. By placing the crankshaft on one of the ribs of the T-plates, determine the heaviest point. Crankshaft will roll over the plates until it stops with the heaviest point down. From this point, it will be necessary to remove a small layer of metal, periodically checking the result.

The timing has a number of features, so it is better for non-specialists not to change its design. Moreover, the camshaft is tuned only in sports interests. If something goes wrong, engine performance will only deteriorate.

The intake and exhaust manifolds on the UAZ 31514 are tuned by many car owners. The first priority is to eliminate the step between windows and collectors. The holes are often not aligned.

Notches inside the manifold bore are removed by rough grinding or more careful polishing. This modification will improve engine performance in terms of uniformity of cylinder filling and improve its performance.
