time to change to a turbo cam... (which one)

Just ordered lt1_edit and the 42 injectors... so its time to sell the NA cam i have in here (cc306) and put in a turbo cam... with 112 is not a good combo...

i wont be running more than 8 psi for now (i'd love to run 10, but on my 105K engine, thats pushing it more than i already am... maybe i'll run 10psi if i need that extra oomph to beat a 500hp cobra or something

)... so what should i get?

this will be

97 Trans am with tune, 42 injectors, lowered comp (as low as i can get it with shaving the heads) bigger heads, 8psi, methanol, and forged tranny... I already have hardened pushrods, springs, RRs and such, so the valvetrain will take the beat...

but anyways, which turbo cam should i go for? i'm going to be ordering from cmotorsports.com

Which turbo?? What rev range? Which turbo system?? All these questions have to be answered before we can choose something for you setup.

Re: time to change to a turbo cam... (which one)

oh yah sorry

its a t04 turbo... its .60 intake AR and .96 exhaust AR... its a sts rear turbo setup tho... i see full boost by 3 grand

i'd like a 3000-6100 rev range, i wanna keep my revs a little less this time (with cc306 it was as high as 6800)

with my current setup, i wont pass 10lb on race gas, 8lb on pump gas

Re: time to change to a turbo cam... (which one)

Any of the first 6 cams would be OK for what you want. I run a 224/220 with .544/.544 on a 114LSA, and It idles fine. It's been a great cam up to 6K. I don't spin any faster than that. The 6th cam might be pushing it for a Hydraulic roller cam, ya wanna keep it under .600 lift.
