Just trying to get an idea...

[MeNmySN95]

Got rid of my procharger, got a On3Performance kit w/ Turbonetics 76mm turbo.

Other supporting mods are:

5.0L DSS bottom end (9.5:1 Cpr)
Very aggressive comp cams / springs / retainers
Stage 3 Ported heads
SCT MAF
accufab single blade
Ford racing shorties
80# injectors
full aeromotive full system
COP conversion w/ Granatelli coils

going thru a fully built T56.

sorry for any typos...im buzzin. :beer:

Lookin for maybe a rough Idea of what I can do on 15# and 20# possibly 25#

First Turbo Cobra for me!

Looking for over 600whp I hope on 91????

It is hard to say where you will be at certain pressure's, but I don't see why you wouldn't see 600hp with that kind of boost. The only thing I would be worried about is detonation. That is alot of boost for 91 octane.

Dont know where in cali you are but E85 is the way to go with a setup that agressive.

 

[MeNmySN95]

No E85 pumps around here

well with 9.5:1 compression i don't think you r going to get away with anymore than 15# if that on premium and still be relatively safe. You will more than likely see 600 in that area of boost but to go higher you will need higher octane fuel like race gas. i'm not a professional tuner consult yours but that is what i've seen and been told by tuners:burnout:
