25.5 psi falling to 22psi HOM/MEH
S3 SST Compressor 50lbwheel Stock Exhaust side
735 cc injectors
AGP Race FMIC
Devils Own Progressive W/I
Maxx Fab 3" S Mc3 DP
Needswing DP McCord Open
PNP Head and Intake
Crane 16's/Cam Gears
60mm Zapp
Ultimate Pipes
MSD coil 8.5 wires DIS 4


The numbers above had one problem...running lean above 5k (13.3 -13.6)

The S3 raising rate regulator would hit 70psi but you could tell when the car hit 5k because the pressure would drop to 55 and would run lean....

What we did...

Hot fix (direct wire)
Bottle Neck Fix
Return Kit (key part for kit...thanks John)

Back to DYNO PAK

430ishHP - running super rich 10 and into 9's AF

Fuel Pressure was down as low as 36 psi

W/I turned off completely

- Swap out 735's for S3 injectors

447HP 465TQ

But the A/F never got above 12.7 for about 3 - 400 rpm mostly high 11's

Boost is where the lost HP has gone and perhaps even better...

We would spike 26psi but only hold 20psi, where as in the first runs and constantly all year at the track 26 falling to 22psi.

So it is either a boost leak or the AGP S3 needs the 18 lb spring...

But with the fuel we now have I think we can crank the boost up to 28 - 30psi range

I will say this to all of the people who told me I would be laggy by 150 - 500 rpm....Try again it comes on 500 rpm sooner and it creates a curve that is almost straight up...

I will be running in the CND Nationals this coming weekend. That will give me some 1/4 mile times and I will post those up.

We swapped back in the 735's and reduced the fuel rate to 45....We now see mid 12's

I will not be able to dyno this setup yet but I will be taking it back to the track and I will update with numbers...

I personally think there is more in the car...I think it has more than 452HP but Unfortunatley until I dyno I can not claim this, it is only speculation...

Thanks to Steve at Fasttrac...Could not have done it without you...Some late nights and some blood but I think we are on the right path!!!

Also thanks to John from PTP for all of the input and knowledge and support to get'r done!!!
