Was the torque kept down on purpose? I want to push my car more but I have the 6 speed and afraid to break it so it's staying the way it is for now.
Yeah we kept the torque around 400wtq for longevity purposes as its my track car. Not trying to have things break. Have many NASA weekends with it, its held up to many 20 minute sessions at full tilt. I wouldn't push the 6 speed that hard though, 375 is the absolute max I would run on that gearbox. Probably even less if its being tracked.
Just wanted to share my results and wanted to know what you guys think. This is on both 91 octane and e85. GSC s2 cams with valve springs and retainers are next on the list.
Mod list:
Stock block and Head(Stock cams)
FP 84mm 71hta w/ 18psi wga
FP 84mm intake pipe
3" TBE
Muse 02 dump
3 port bcs
Synapse DV
Vrsf 3.5" intercooler
Muse licp
Walbro 255
RC 1200cc injectors
Interesting, I wonder if my car started with your tune with the addition of MIVEC map. Mine was also tuned to 28 psi tapering to 24 at redline. I have the stock IX WGA and MAP O2. Did you port your exhaust manifold or hotside to match up to your O2 dump?
So S2 cams and race manifold got you about 55 extra hp.
Why was your boost held at 26 psi on E85? Did you hit 100% IDC? Who tuned your car?
And your spool looks great without mivec.

Yes with 2 psi less, which is nice. car pulls good and the S2 lope is addicting
Im not sure what the IDC is at but boost was left at 26 psi upon request. Did have a run at 28 psi, was told power stayed around 450 but torque bumped up to 400. Wanted to play it safe by keeping torque under 400 wtq.

Mine was tuned for 28 psi boost and on cool nights, I see 32-33 psi boost around 4,000rpm and then it tapers. If I'm at 425 ft-lbs of torque at 28 psi boost, I wonder what it gets to with 33 psi.
