Hey guys i dont belong on the diesel part of the forum but I was wondering if anyone knew how much boost you would have to be running at get 400 hp from a 2000 cummins motor? Its a little vague i know but i want to know for a discussion that is going on in another forum on the gassers side.

 

Hard to say is it a 12 or 24 valve?? I might be getting close with my 12 valve and i am only using 40lbs if boost right now ...exaust and intake make a big differance as well as injectors..

Opps sorry i did not see the 2000 so it is a 24valve so i am guessing when i am saying you would need a bigger pump as well as a good programmer and exaust to do it ...so my guess would be 50-60psi the thing is it all has to work together programmers ,turbo,injectors,intake,exaust..boost is just part of the problem to making power but it sure helps..

 

Alright just what i was figuring. Thank you

 

Heh, on the HPCR trucks it just takes a programmer and exhaust to hit over that mark.

 

boost pressure has nothing really at all to do with hp.... its all how its delivered, we have a guy here that put almost 800hp to the tires on 38psi of boost if some ous says i stacked these programmers and i noe have xxx amount of HP they have no clue what they r talking about, its uasually bout half what they think it is, a dyno is the only way to prove anything....
