Boost???

[Fast73Excursion]

I'm sure there has been plenty posts on here about this topic, but...

How many pounds of boost can the Stock 7.3 Head Gasket Configuration take? Lets say on a 2000...


Just curious...

Anybody???

Not sure of the exact psi but its not a common thing for headgaskits to blow on 7.3's Seems to me its good to 40 plus psi could be more.

stock headgasket with stock head bolts = 40psi
stock headgasket with head studs = 55psi



Fast73, you will run into rod problems before you will lift a head. hybrids and a GT38R(shut up you TN guys) have a proven 450hp. That is with 37-40psi of boost. So, with a 2K PSD, you have PMR's and they like to snap or brake when you go over 400hp.

What are the limits on the OBS trucks?
I m waiting on my D66, Stage II's, and 17* HPOP

There on the way!!!yikes:

40psi for the OBS as well. the D66 tops out at 40psi as well.

You are going to be very happy with that combo you are getting.

I hope so... What kind of #'s should I expect? The engine has alot of miles but runs GREAT.... Plus it is intercooled, custome tunes and of course intake , exhayst, and guages..

Mid 30's right to 40psi depending on the tune you are running is what I would expect.

What about a Hp and TQ estamite?

[strokin_early_99]

Edging 400hp on an extreme tune. That would yield about 800+ TQ.

I made 471hp with my D66 and 240cc B code injectors. Bean was pissed at me when he found out I went with B codes with his D66.
