Which car?

Stang should be mid 11s.
GTR stock with a boost controller low 12s
Project car should be mid 9s, with a little luck
Boss 302 low 13s
GTSt in high 13s

You know what i think we got off at a wrong start lets start over, well what did you do to your stang to get it into the 11s, i'm planning on doing either turbo or supercharge my maro, but i'm leaning more towards the turbo i think that should get me into the mid 11's

I have a friend with a 93 Camaro, and he is fighting for traction, and has yet to break into the 13s.

LT1 is a good engine, but as far as boost it depends on what comp ratio you are at?

I run an S-Trim on the Stang, but you can always get more power/torque from a turbo.

What cam are you running?

[SMOKEY818]

it's a stock cam, but i'm going to get in a month the lt4 hotcam, and tell your buddy to get the full hotchkis suspension that should help out with traction, i always wanted a supercharger but i realized you can get more hp/torque from turbos

What are the specs of the LT4 cam?

Whats your comp ratio?

[SMOKEY818]

@ .50 218 intake, 228 exhaust
lift 525 (with 1.6 rockers)
lobe sep 112deg
compression is @ 10.5 to 1

That's just it, the cam is more suiting for a supercharger, but your comp ratio is a little too high for boost, so you have to change some internal out, or go aftermarket head with bigger chambers. Turbo cams should have a wider lob sep. I will be running 114, some guys run as much as 117.

I would think either N2O, or start saving for some new heads to lower the com ratio would be the best route.
