mobythevan Posted January 15, 2006 Share Posted January 15, 2006 For 500 hp in a 454, one would think that forced induction is unnecessary. With good heads, a roller cam and "proper component matching" (as the mantra goes), 500 hp with single n/a 4-barrel on a 4000-rpm torque peak and 6000 rpm redline doesn't strike me as at all exotic; at least, that's essentially the goal for my own car. That is true, but you can have a small cam with forced induction and I have to play with a supercharger some time. It will also be a difference of making 500hp at 4500 rpm with blower versus NA making 500hp at maybe 5800. Quote Link to comment Share on other sites More sharing options...
Chaparral2f Posted January 16, 2006 Share Posted January 16, 2006 IMHO, before the dabate about whether it would make 500 hp gets too far along, there are a couple of things to consider. Its easy to say a bbc with a roots blower won't make a lot of power, and although I agree that a lot of blown street cars are doggy, a well setup blower motor can make a ton of power. I'd want to hear from the owner about what has been done to the engine. After all 454 is just a start for a big block. (you can get that much out of an aftermarket small block fer crissake!) GMC blowers come in lots of sizes.(I think a blower off a 3-53 detroit engine would be neat on the vg-30 that is sitting in my garage.) The blower off an 8-92 would be just what the doctor ordered for a built big block. Not only is the size of the blower important, but the pulley that drives it makes a difference, when one of those gets overdriven, the boost goes up FAST. A for at he blower sticking up too high, I have a suspision that this thing wasn't built to be a sleeper. (I could be wrong of course;) ) Quote Link to comment Share on other sites More sharing options...
