wll i have no idea where to post this but im looking at a jet chip pulleys and tune for my camaro. What kind of hp gains am i looking with a decent tune ,jet chip and puleys? im pushing 380 with simple shit like cam, headers, full slp exhaust and simple push rod replacement and ignition. any ideas?

 

look up the hp gains for the pulleys, I think it's like 7-12 hp. If you happen to get the alternator pulley and not just the crank pulley then you won't have power issues, however your a/c will suffer (if that's important) as will any other items that are driven off the serpentine...like power steering and the water pump. The lt1 runs hot as it is so if this is your daily driver then I would avoid the pulleys, the gain vs. loss isn't worth it.....however if this is meant to be a racer then go for it. I have a crank pulley on my lt1 that I plan on pulling off as soon as I can, all my accessory pulleys are stock so everything is underdriven and this is a 70+mile a day driver so it is all important for me. What cam and valve train setup do you have? I have heard of gains like yours from the lt4 hot cam kits with just port matching and exhaust.
