ive got 42's meth running boost juice and a 3 inch pulley.
i will have a full exhaust soon right now ive got 1.75 primary 3inch downpipe to dual 2.5 exhaust

i think im gonna have a 3icnh intake and bigger tb not sure yet but...
how small of a pulley do you guys think i can get away with? i was thinking 2.8 but some people have pushed luck with 2.7s
also how small is too small for the supercharger?

i know its been asked before but with the meth on we kept pulling fuel out of the top end so i think i can push more boost with these injectors than i would be able to otherwise

 

with a good tuner you can get way with a 2.8 a 2.7 would be to small for 42's you would need 60's for that

 

i would sell of the 42's and get the 60's gives you much more room to play safely and expand in the future

 

ok thanks i just wanted to make sure i know its been beaten to death, but every mod makes diff things possible

and i dont plan on doing anything more with the motor after the pulley. ive got other projects to make go fast this is still a daily driver

 

yeah we all say that. its addicting though. I still suggest the 60's but again its your and your tuners call

 

i do have a fast car sitting at home i just wanted a bit more out of the cobalt. ive almost got it to where i want it, im thinking the pulley will put me in my place
