93 Mitsubishi 3000GT VR4 – dyno tune

Posted by x99percent on November 10, 2010

Displacement is fun. Big turbos are fun. AWD is fun.
Displacement + big turbo + AWD = FUN.

The basics:

  • AEM EMS Series 2
  • Stock 6G72 3.0L block with forged internals
  • Ported stock heads
  • Brian Crower 280 cams
  • Borg-Warner S400SX3 turbo
  • custom manifolds, exhaust, intake, intercooler, and throttle body
  • RC 1200cc injectors
  • Aeromotive FPR
  • E85 fuel
  • HKS DLI
  • Blitz Dual-SBC Spec-R boost controller
  • only 23-24psi… for now

There were no mechanical issues with this car at all, which is always welcome.
Considering the size of the turbo, boost came on at a very reasonable RPM… thanks in part to a device that makes the turbine inlet smaller at low boost levels. Once the turbo was spooled, the boost level was controlled *perfectly* by the Blitz EBC. As the boost was turned up, the car responded very well and power levels continued to rise. Minimal changes in fueling were needed for the additional airflow, thanks in part to the boost compensation mapping in the AEM EMS.
