Default How much RWHP on cam only, stock ls1 head/intake??

How much RWHP would you expect on stock ls1 head/ls1 intake motor with a 227/230 .580/114 cam , headers/exhaust, pulley,cold air etc???

Could you hit 375 rwhp?

Cam only? With most bolt ons?

The hp should fall in somewhere around 360 to 400rwhp depending on whether it is an M6 or an A4 and what size cam ... and if you decide to get some PCM tuning done or not.

HOLY EYES BATMAN!! Raughammer does live!! Yo I shot you an email brother, get back to me on it.

Soundmn: Since you have the 241 head castings and they seem to flow better than the 98/99 castings, with ALL the bolt-ons and the X1 with VERY GOOD tuning you should hit the 390-400 mark....

I can't speak for Raugh and I know his set up is very similar to mine except he's got the LS6 heads but we're well into the 420hp range w/the H/C set ups from MTI we have. If you are set on not doing heads seriously try the G5x2 or the new G5X3 they seem to be getting consistant 400ish rwhp on stock headed cars. Just my thoughts.

going to get heads(as soon as I have enough money saved up for them.....working on that now)but I'm gonna really spring for good heads......I have a goal of around 450-480...and with heads I will be there...plus I have a pretty strong car...not a freak by any means......but very close to one....I should easily hit 400-410 with the few boltons from above.
