how much compression is in a stock 03-04 cobra?

MM&FF says they got 1188rwhp & 1015rwtq on stock motor......is that possible.
they called it the Manhattan project p 126 of jan 08 edition

 

yes it is, that set up uses compounding boost which is a whole different ball game i am sure i can fid the forumla for compounding boost somewhere. i know that with 16-18 psi on the turbos and 9 psi on the blowr the pressure under the manifold reaches something like 41 psi. seems like doing it this way does not stress the motor as much.

 

yeah, the hellraiser kit from hellion, which can utilize twin turbos with the stock eaton. with the turbos set at 26 psi, after the stock eaton with the stock pulley, total manifold pressure was 42 psi boost. i would think the air temps would be hella high, and very dangerous, unless running on 109 octane...

 

Nahhhhh! Just throw a little 100 bhp shot of N2O in there to cool it down!

 

well after that, they set the turbos to boost over 30 psi, and that lifted the heads off the engine!!! no joke.

 

heads start to lift around 30 psi at least with the stock head studs.

 

damn thats some cool ****, how does it work to where it doesnt kill all the internals

 

not too sure i thought they gave a brief explanation in the article but i don't remember off hand

 

im gonna go back through an reread it again, maybe that'll help, but im looking to you guys to help the most.

 

i read it once again, and i still dont understand compound boost...someone teach the redneck!
