So my friend Brian and I decided to test out where I was standing with the 57 trim @ 16psi.
First, the cars:
Brian's - 2000 Chevrolet Camaro SS
LS1 motor, stock, 80k miles on it.
LS6 intake
3400rpm stall converter
HP Tuners (still tuning, though it is better than stock, lol)
SLP CAI
SLP exhaust
John's (mine) - 1988 Toyota Supra Turbo
7MGTE, stock, 212k miles on it (fresh Felpro gasket + ARP head studs)
57trim CT26
3" elbow
3" exhaust, no cat, with a freaking Flowstopper (aka Flowmaster) muffler
2.5" hardpipes
Aaron's bigger Spearco replica
MAFT-Pro, tuned to 11.6-11.8 AFR @ WOT
16psi
Results:
We decided to do two runs, both from a roll.
First - 30 mph roll, as we figured this would be his 'sweet spot' with the tq converter + the fact my damn a340 hates to downshift. He honks 3 times, we nail it, and he immediately pulls on me. Puts about 2-3 buses on me. Run to 135mph - from 100-135mph, he stops pulling on me.
Second - 50mph roll - better spot for me, as the tranny WILL downshift from this point! He honks three times, we nail it - instaspool! He still pulls ever so slowly on me, and from 50-125mph, he puts about 1.5 cars on me.
His last run at G'ville raceway was a 12.7@106mph, on a 1.8x 60'
Ok, so not doing so bad, right? He noticed I was blowing some smoke under deceleration, I chalk it up to needing a catch can (stock PCV routing currently). I get to Advance in G'ville (off University/Waldo) and what do I notice? Blowby! Also, not pulling my usual 23" of vacuum @ idle (now about 18"), as well as a weird 12.9-13.2 AFR @ idle. 0.0v Vf, from a normal 2.5v Vf , with a sweeping 14.5-16.5 AFR @ idle :3d_frown: Letting her cool off now, so I can go check the compression + spark plugs, and see if I can figure out what happened
Good thing I have the next week off!
