Stage6 Motorsports put in a set of GSC S1 cams (along with converting to shimless buckets) and then sent the car to MASE Engineering for a complete re-tune.

Mase uses a Dyno Dynamics Dynamometer (load bearing chassis dyno) for tuning, so the graphs below are at least 10% lower than what a dynojet would have recorded. Mase tuned the car from scratch, and these graphs were recorded after many, many pulls to simulate how the car normally runs after 10-15 minutes of being on track and everything heat soaked.

Here is a link to an short in-car video: http://vimeo.com/29216878



My car is a dedicated road race track car, a few of the details:
  • GT35R with 0.68 housing
  • AEM v1.0 Tuned by Mase Engineering
  • GSC S1 Cams with shimless buckets
  • Greddy header and wastegate (from a T78 single turbo kit)
This graph shows RWHp & RWTq (DynoDynamics Machine - not DynoJet)






This graph show RWHp and BOOST (DynoDynamics Machine - not DynoJet)




The boost is hitting almost too hard, so we will be back out in late October to finish the fine tuning when at the track.

Overall, I could not be happier. Dwight and Mase were able to finally fix the boost control issue I was having and the car has never been so powerful on track to date...
