APR Presents: Audi B8 A4/A5 & Q5 S3 K04 Turbocharger System!

[Arin@APR]

PR 2.0 TFSI Valvelift S3 K04 Conversion System

APR's S3 K04 Turbo Conversion is now available for the Audi B8 A4/A5 & Q5 2.0 TFSI Valvelift engine. APR has developed an excellent entry level turbocharger upgrade for the 2.0 TFSI VL engine by incorporating the OEM turbocharger assembly from the Audi S3 and coupling it with APR's expertly recalibrated engine management upgrade. APR's Engineering Team has developed a powerful and reliable turbocharger upgrade that maintains OEM engine bay appearance and offers up to 116 hp and 113 lb ft of torque over the OEM power output of the 2.0 TFSI.

Reliability, drivability, stealth and enhanced performance that cannot be bested are the highlights of APR's newest OEM-component based conversion package.

APR's engineers have expertly recalibrated the engine management system to allow for nearly flat torque delivery from 2800 RPM to 5000 RPM which results in a smooth linear pull throughout the power band. Keeping the track enthusiast in mind, this conversion package will not result in overpowering of the driveline but will allow for smooth acceleration to easily maintain control while cornering.

The Borg Warner K04 turbocharger selected by VAG engineers is perfectly sized for the 2.0 liters of displacement to allow for stout horsepower numbers as the RPMs increase with no dramatic fall off as redline approaches. This ensures plenty of power in the high RPMs for continued acceleration in the straights and positioning at the healthiest portion of the power band after corner exit.

S3 K04 Conversion Package



Optional OEM Exhaust Compatibility
While a full exhaust is recommended for maximum power, If you're in a situation where running a high flow exhaust is not permissable, APR has also developed software specificly to use with your OEM Exhaust system. You may switch between high flow exhaust software or OEM exhaust software free of charge any time you alter your exhaust system.

APR's Patented EMCS Technology
Featuring APR's Patented EMCS program switching functionality and DirectPort Programming, APR's Engine Management Calibration for this conversion package allows for a range of Octane and situation specific calibrations to be installed simultaneously on your vehicle's ECU. These programs and features are able to be cycled through via your existing factory cruise control and activated in less than 20 seconds. You will be able to choose 1 to 4 Programs listed below. You will also be able to add APR Security Lockout, APR Fault Code Erase and APR Anti-Theft features.

Not to much difference in performance then a FSI or TSI K04 setup for having such an expensive head design.


for building the kit though.

I don't know if I would necessarily say that primarily because each system was compared on different drivetrain's and transmissions. Estimating crank figures between 6MT, Tiptronic, Quattro and FrontTrack is a bit difficult. Some may say we are selling ourself short as we have chosen to report crank figures on the B8 with a rather low drivetrain loss but I personally feel more comfortable erring on the side of underestimation rather than overestimation.

Once we start seeing more of these in the field on multiple dynos and such I'm sure you'll find the new VL head is producing slightly higher figures than it's non valvelift cousin.

Understandable..

Does the VL head flow less then a non-VL head?

I don't think so. I'll check with engineering on monday for some numbers.

Just noticed this motor makes more torque then non-VL head but less HP. I know through cam timing that can be changed and valve lift in the case too but I am sure you all maximize everything to a safe limit as always. So I was thinking maybe there is a limiting factor in the system somewhere.

Arin,
You mentioned intercooler, exhaust and intake are all recommended. However, I can't find pricing or descriptions of any of that stuff.....either on here or on APR's website. All the tests include the exhaust, but if you don't actually SELL the exhaust how would one go about achieving those numbers?

The exhaust system will be on sale pretty soon.


We do not have an intercooler system yet but we do have an intake on the way. When I say I recommend them it's because I do. A properly designed intercooler system will absolutely lower charge air temp and increase HP or keep it longer. The same goes for a properly designed intake system as it will increase mass air and allow for better results.

What about this TSI KO4 kit from you APR for the A3's?

[Arin@APR]

Not ready yet!

[Ricky Bobby]

Not ready yet!

I'm assuming when the kit is ready it will be utilizing stock intake (and/or aftermarket) like this setup for the B8 audi does? if so thats friggin sweet, since i could upgrade to k04 and not have to buy new hardware (already have s3 intercooler and 3" TBE)

Yup, we are looking to make it compatible with everything as if it was still the OEM unit.

Arin,

Any issue with the B8 Tiptronic models?

I have an 8 speed Tip and understand this similar ZF Transmission is in the Jaguar and Maserati and Porsche?

Will pull the trigger when given the

We've installed this on a couple in house tiptronic cars w/o any issues.
