Now that I finally have my cooling mods installed I've been thinking about going with a 2.8" pulley & a custom dyno tune. My question is, is it safe to run a 2.8" pulley on stage 2 42# injectors? Also how much psi would I be running w/ this setup?

 

No not safe, dont go smaller than a stage 2 pulley unless your going 60's

 

you can go a 2.9 and be ok with that but nothing under that unless u have 60s and cooling mods

 

Well that shoots down future plans. Thanks for the advice guys. Might as well go big now, 60# injectors, 2.6" pulley, dyno tune, & methanol injection.

 

Bad idea indeed. All it takes is time.

 

the lowest i would go with all the cooling mods is a 2.7

 

Keep the suggestions coming guys. I'm open to any & all ideas. I want a reliable daily driver that I can be proud of on the track & impress occasional "V8 guys" on the street.

Current setup:

*GMPP stage 2 kit
*InJen CAI
*Custom 2.5" cat-back

 

i have a 2.8" pulley and stage 2 injectors, and it seemed fine for a time but after over a year with that setup the car cant go much over 6k without acting up. i do not have money for the proper injectors and tune but my co-worker has hptuners and i was thinking for $50, couldnt I buy the credits and use the boost control solenoid to a different duty cycle and decrease boost in the high rpms so that my injectors dont go past thier duty cyle and i can rev it up to 7k again?

 

you could just limit the boost in all gears to about 75%, but what fun is that? just get 60#s and download a tune.

 

Go 2.6, 60's, meth, h/e, header, and downpipe. People are too afraid with the smaller pulleys. They are fine with proper tuning and not driving like a jackass

 

If I do get the 60# injectors I'm going to want a smaller pulley then a 2.8" If I spend the money I want full potential of what those injectors are capable of.

That's the option I've been thinking about. I already have the dual pass intercooler plate & big front mount heat exchanger. Is the S/C snout going to need to be shaved down to fit the 2.6" pulley is my only concern?

 

I have a 2.6 & 60's with all cooling mods. The car has been fine for two years. Like wicked said, with a proper tune, a not beating on it daily, it will be good.

 

if you want to use the full potential of those injectors you will need alot more than a 2.6"
more like TVS or Turbo. not to mention those will net way cooler cylinder/intake temps than a 2.6" on a Heaton blower.

 

That is true. TVS is the best way to go if you do not want to do a turbo swap. My 2.6 pullied car was fine for 8 months and a few trips down the track w/o cooling mods, but I wouldn't do that again. If you order a ZZP 2.6 it'll fit the ZZP or Intense hub and not need machining of the snout.

 

What is this TVS you are talking about? The only S/C upgrade I've seen is the one from Over The Top Performance.

 

yes this is the way to go

 

2.8, 60's, plugs and a tune is safe right? Stock h/e and exhaust (for now)?

 

and that my good sir, is the TVS they are talking about.

 

Oh, gotcha. Just wanted to make sure

 

yes yes!
