hell if I know, most hp i've ever heard of on a busa was 901 hp, not sure if it had an intercooler or not, but it was a street bike........
THe boost you need to achieve a given HP number is totally related to the intake tuning, if you have a very efficient intake (porting, intake turbo housing efficiency etc.) you will require less boost then an equally setup engine less the efficiency. (Make sense?) The fact is with good tuning and the right setup, I think Yoshi's numbers are totally reachable with the basic setup he listed due to the fact that he lowered the compression. Make sure the Quench distance (piston to head deck, not chamber, clearance) is as tight as you can run safely on that particular engine (likely around .060" but check to be sure) and you will be good to go! The tight Quench clearance speeds up the mixing motion of the mixture in the chamber and reduces the chance of detonation.....Just like an Indy car!
I'm just saying I feel you have been misinformed.As to the astounding claims of the engines mentioned, plese consider what is physically possible:http://www.epi-eng.com/piston_engine_technology/bmep_performance_yardstick.htmIt's this understanding, as academic as it is, that has the more crusty among us (who me? get off my lawn!) muttering "on the street? BS!" edit: (just for Jet)According to my back of the envelope scratchings I get a BMEP of 182 for a stock bussa. Much above 200 is ... well read the article
Sorry Yoshi! We are bustin' up your log again!New thread time Fabr?
yeah, go ahead and split this one, again, lol........
Sorry Yoshi! We are bustin' up your log again!New thread time Fabr? All kinds of good stuff!
New thread? Lets talk TURBO'S?
How can you call something "street" that needs a FULL rebuild every 30 hours (or as little as 3 quarter mile runs)
