This is my first post on this site, I want to know about how much horsepower I should expect to have after all these parts are installed on my 2006 cobalt SS LNF Supercharged! This is my first tuner car so I'm new to all of this. Here is the parts list:
-zzp 2.5" midlenght header
-zzp 2.5" midlength catless down pipe
-zzp 2.5" cat-back exhaust w/resonato
-zzp 3" cold air intake
-zzp stage 3 kit with 2.8" pulley
All of this will be running on a premium 93 octane tune. I'd like o know the horsepower with a 2.8" pulley and also if I got a 2.7" pulley. I appreciate any and all feedback! Thanks for the help guys!

 

Just no.

 

Lnf supercharged wow thats funny

 

My bad, LSJ, like I said, I'm new lol.

 

You can look up people with gms3 tune and what pulley they run. It's been done

 

Theres a dyno thread on here...

Around 260whp

 

My butt dyno says 250..

 

250 ish whp. check the dyno thread. a lot of guys have that setup. I would get a custom tune.

FYI I ran a similar setup a few years ago and it put down 260whp with a spot on tune... power was still climbing at 7k redline.

 

gmstg3 and zzpstg3 are not the same

 

I feel like I'm on the Facebook page.

 

with a zzp canned tune .... i wouldnt recommend that

 

245.856 hp @ 7063 rpm
