Description

Steve Dinan has over 40 years of street car turbo experience. As an engine supplier we won 3 prototype racing championships and two overall wins at the 24hrs of Daytona partnering with Chip Ganassi Racing. No one know more about tuning high performance engines than our team.

CarBahn software is designed to deliver the highest safe output possible. Smooth Power means software tuned correctly, not over-tuned. Excessive torque will break the tires loose, break the engine and drivetrain. Managed torque with a smooth delivery makes the car easier to drive thereby faster and more reliable. Most if not all our competitor’s tunes attempt to run too much boost, resulting in active knock corrections which causes surging during acceleration.

We tune our cars to be great street or track days cars, not for a maximum dyno number. We are road racers, and we want a power curve with at least as much HP as torque so the car is drivable. We expect our cars to run 100,000 plus miles after the car has been modified! We tune for low turbo lag, excellent drivability, and durability. We also keep all the smog equipment on the car.  The cars that make more power typically have very short lives before they experience engine and/or drivetrain failure. They won’t pass a smog test and commonly have so much torque and turbo lag that the drivability is poor.

 

We are introducing the CarBahn Autoworks Stage 2 Power Package for the M4 GTS:

 

635 flywheel HP | 624lb-ft flywheel torque

Light Red = Stock | Dark Red = Stage 2 Power Package

Included in Stage 2 Power Package kit:

  • CarBahn Autoworks Stage 3 performance engine software
  • Pure Stage 2 turbocharger upgrade
  • CSF top-mount intercooler and front-mount heat exchanger upgrade
  • Optional: Maximum PSI crank hub kit (required for matching warranty enrollment)

 

Notes:

  • This Power Package includes a turbocharger upgrade, which will require a $1900 core deposit that is refunded upon return of the OEM cores back to CarBahn, unless the stock turbos are sent in first.
  • A Maximum PSI crank hub kit must be installed in order to be eligible for warranty coverage through CarBahn.
  • 50% methanol mix in the factory water injection tank is recommended.
