Yesterday was the day to take care of FINALLY getting my car tuned.
Here is a brief rundown on the car:
Brand new (3000 miles on it) stock bottom end
PHR stage 2 ported head
Twin in-tank fuel system w/ 720 injectors - RRFPR, etc.
VPC/GCC/Profec B
RPS stage 3 clutch
HKS Type S FMIC
Stage 2 turbo
We filled the car with 118 race fuel and put new plugs and a new O2 sensor in the DP for the tuning. The car was strapped down and Jarrett began the tuning. As expected it was running dog rich... off the A/F scale from about 4200-5500
RPM. Slowly fuel was removed and the power started to come. I'm not going to bore you with the play-by-play. So here are the results.
At 18 psi it put 500.3 hp to the rear wheels - Torque was 442.8 ft/lbs
At 20 psi it made 537.2 RWHP and 473.2 ft/lbs... the torque curve is very nice.
From about 4300 all the way to 6500 it was over 400 ft/lbs...
From 4600 - 6300 it was over 450 ft/lbs.
Then it happened... We ran out of boost controller. For whatever reason the Profec B simply would not allow more than 20 psi... even with everything maxed out. I was not too happy! The Profec will be hitting the trash can soon and be replaced by a HKS EVC EZ.
I really wanted to see what it was going to do at 26 psi. But with the numbers it made at 18 and 20 psi I am pretty confident that I would have seen low 600's. I think the next change I will make will be to go with a larger FMIC... probably the Type R. I have a feeling that the Type S simply cannot flow enough air to let the motor/turbo get to it's full potential.
Considering the weather here in NC yesterday was VERY nasty. It was in the mid-90's with high humidity all day, I am very pleased with the reults of the 18 and 20 psi pulls... and with the car. It's an absolute blast to drive.
I had about 20 minutes of play time (dry roads) before the rainstorm-from-hell started in Raleigh. The car is un-real. Traction seems to be an issue until 4th gear. I can only imagine what 26 psi will be like. I'll let you guys know when the EVC EZ goes in and I take it back to the dyno.
I'll try to get the plots posted somewhere so you can all see them.
