BAR-TEK® TIP!

BAR-TEK® tips!

We recommend filling up with 102 octane fuel. This will give your engine more power because it knocks less! The engine should be in good condition and the turbocharger should not be too old. To reduce coking to a minimum and keep the engine clean, we recommend installing our oil catchtank kit with TÜV.

To bring the extra power on the road, you need a sport clutch, because the original can not transfer the power. For the conversion to K04-01 upgrade turbocharger you have to install a 3" downpipe and our upgrade air mass meter.

BAR-TEK® TIP!

We recommend that you buy the Level 3 Kit right away. With the level 2 kit, without modified injectors and upgrade manifold, the performance gain compared to chip tuning is not quite as high. This is because the 180 hp 1.8T engine already has a slightly larger turbocharger.

With the tuning kit stage 3 you have the extended extension stage of the kit 2. Here you have 380 ccm injectors and an upgrade manifold as well as an again optimized software! If you have already installed a downpipe, an intake hose and an upgrade intercooler, you can continue to use them. With an upgrade intercooler you also have the complete power available in summer!

320 hp: That's an announcement! To drive this power, you have to replace your connecting rods with h-beam connecting rods. A sports clutch kit is required to make the 320 hp perfect. For the exhaust you should use a 76 mm exhaust system. For the correct oil temperature, an oil cooler must be installed!

BAR-TEK® TIP!

A good chip tuning is required for this conversion. You can send us your control unit or have your vehicle tuned directly in our dyno. Another tip from us: If you have installed the small 280 mm brake system, this is no longer up to the high performance. You can convert it to a Brembo 4-piston brake or a 320 mm brake (e.g. from the Audi S3).

This is how you improve the cooling:

If you want to get the full performance out of your engine, you must not forget the cooling. Even a little extra power puts a lot of strain on your engine! The thermal load increases and affects all areas of your vehicle, even the transmission suffers from the new power. At best, the hard-earned power is reduced again; at worst, your engine suffers major damage. So that you can tune your engine safely and reliably, we provide you with everything you need for perfect cooling. Although it is ideal to install all parts together in a cooling bundle, you don't necessarily have to order everything at once. Each product helps you to improve cooling.

The perfect turbocharger for your tuning project

The turbocharger is one of the most important tuning measures of all, as there is huge performance potential in the compression ratio. This is why you will find all the turbos from the guides and suitable alternatives in this special turbo guide, for example if you prefer a specific manufacturer. We have also compiled a lot of information for you on the subject of turbochargers, which you should take a look at. In addition to the detailed turbo tips, there is a page on running in engines correctly, turbo lag and, of course, our 14 turbo rules.

Racing engines from BAR-TEK®

If you don't feel like tuning your engine all by yourself, you can also get a ready-tuned engine from us. Our racing engines are designed for maximum performance and maximum driving pleasure and leave nothing to be desired. The components included are perfectly matched, finely balanced and suitable for the highest speeds. Because we use components from motorsport, such as forged pistons and steel connecting rods, our racing engines are extremely stable. This means you get a completely finished engine that not only delivers full power, but is also safe and has a long service life.

The performances stated here are based solely on our experience, therefore we can only give a reference value. Many factors, such as the fuel used, the software setup and the mileage, play a serious role in the maximum possible performance. Therefore all data are without guarantee. If you would like to put your engine through its paces, we will carry out an exact measurement of the value on our MAHA dynamometer.

Any questions?

We will be happy to help you! For further questions please contact us by phone or e-mail.
