no, no and no. you can make a head stay on with 30psi. its been done. 6psi is not going to give you 100hp on a slant. just not gonna happen. maybe 50-60hp. 30psi on a slant CAN net you just over 500hp.
While it's a good rule of thumb (has been done twice anyways) keep in mind it all depends on the turbo and such. If I'm correct, Tom only made ~300@crank with 23lbs on his first setup. Just something to keep in mind.
