RESULTS: LT's on a 2v s/c
Ok, so few weeks ago i installed long tubes (mac), went from a 3.33 to a 3.12 pulley, and changed my stock BPV to a bigger proflow unit from procharger.
Previous best was: 425 rwhp (v2 intercooled, 3.33 pulley, power pipe, tb/plenum, o/r h, catback)
Now after 3.12 pulley and LT's its at 433 rwhp.
Given that today was warmer (~80*) and it got dynod about 20 mins after i pulled into the shop the peak hp was not much at all. Earlier this year in january i made the 425 (had been resting for hours and it was a cold day ~50* tops) Just thought id let you guys know for whatever it matters.
power/tq DID change though, its the same curve but it just comes on a few hundred RPM sooner which was was i was going for anyway, wasnt too concerned about peak gain cause im still on a stock longblock.

That's interesting! When i swithched to long tubes and a shorty catted h (i had a catted MRT h before) i gained 6 rwhp and 6 rwtq n/a, and 20 rwhp and 57 rwtq on nitrous.There was no changes to the nitrous or n/a tunes either. The a/f remained almost the same.

tuned at houston performance. like i said i can feel a difference, but the numbers arent there...
i bet when it gets colder out itll respond MUCH better.
u know how it is GTRACER, it was in the 50's last weekend and now its near 80 :P
