Default can you get a LS1 over 350whp without opening it up?

Without adding nitrous or forced induction.. just with simple bolt ons not counting cams and stroker kit and heads..

Intake is accepted tho, can you get a 2002 ls1 engine above 350whp? if its attached to a t56 tranny??

im just wondering if a fastx intake and throttle body, full length headers and full open dual 3" exhaust and cold air intake system etc can get ya around that 350whp mark or not?? anyone got an idea?

Youre better off with the LS6 intake because youll loose hp and tq accross the band with the FAST and no heads/cam.

Its been done numerous time to get the boltons LS1 around 350rwhp/350rwtq. Full exhaust, U/D pulleys, ported TB, lid, tune, LS6 intake and you should be right there.

Full intake/exhaust and a tune. That should get you there or really really close!

I got mine to 349 RWHP with bolt ons. I could have broken 350 if I had installed an underdrive pulley, an electric waterpump, opted for no cats, or ran a LS1 clutch instead of the heavy LS7 clutch.

Bolt ons were LS6 Intake, ported throttle body, longtube headers, true duals and lid.

HP peaks in an awfully strange place for an 02 F bodies if you ask me. Simply a lid will not net 340+hp to the wheels on an f body, sorry.... but it sounds like bullshit to me.

It may be hard to believe but as for Raptor he has Dynoed the car 3 times on 3 different dynos and the car keeps putting up similar numbers everytime.

Where should an f-body make peak power at then? The graph looks about right. He was asked for proof and he provided it!! What else do you want? Some cars are just factory freaks!!


Quick Reply: can you get a LS1 over 350whp without opening it up?
