R/t of 1.031
Now I want better times... In the very near future I will recieve my hptuner and I don't know the pulley size for the M45 that give 10 psi ???
I heard 2,6in or 2,7in.. is it true?? I don't know shit about the m45.
and if I change the pulley size, do I need a shorter belt ???
for now the beater ( old car of Vinalero ) have :
Gm s/c kit
180* t-stat
H.O. alt, 200 amp
2,3H.O. TB 57mm
Pacesetter header
Straight 2in 1/4 exhaust with no cat or resonator, only a dynomax super turbo muffler
WAI, not yet a CAI, I'm gonna put the battery in the trunk ASAP
I'm running on radial T/A 215's at 20psi on the track
also I have a short shifter
Cm coilspring and GR-2 shock
Crossdrilled and slotted brakes...
I'm waiting for your opinions on what I should do next.... CAMS, PULLEY, N2O

how many runs did you get on the track?
get thicker rubber, battery in the trunk under the hood no care, 2.5ich exhaust, smaller pulley, tune, meth injection.... you'll run better for sure. But just so you know that s/c is too small to do any real work on the dragstrip.
My opinion is sell the s/c and slap together a simple t3/t4 setup, or a tasty GT30 garrett. Tune it and if you don't hit a mid to low 13 out of the box we punch you.
