increase power but not boost?
increase power but not boost? i currently have a 01 ls1 with ls6 intake manifold. mpt76 turbo at 8.5 psi and make 482rwhp and 502 torque.
would changing to a better flowing head and mild cam increase hp and tqe safely or would i be better off just raising the boost a few lbs and tuning for it?
is there a better flowing oem head that you would suggest? i read alot about changing heads to lower compression in order to raise the boost lvls. also what cam would you suggest? i dont want it to sound like a heavily cammed car at idle. the more stock sounding, the better

what is your goal? If its around 550 i would definitely try raising the boost first. Maybe to 11lbs or so. I wouldnt spend the money on heads just yet. another idea is just getting a better turbo like a gts76mm.

Much easier to raise the boost and with a good tune will still be just as safe.
Only oem cylinder head I would go with over the stock ls1 heads would be 799/243. They will raise your compression a fuzz but the combustion chambers and ports are much nicer and make more power.

Any ls motor boost or not normally responds well to a good cam. I have a procharged 02 z28 on 8.5 lbs of boost and I put down 562 whp and 519 tq on an mustang dyno. My cam is 232/238 .595/.605 lsa 115. that may be a little to aggressive of a cam what you want but its food for thought. dont forget to upgrade the valve train if you do a cam.

You could always splurge and put a nice set of ported 799/243 heads on it with a nice cam and raise the boost a fuzz. You'd really be looking at a nice power gain then!
