Default Just curious....cam for 9k rpm?

What type of cam(duration, lsa, etc) would make power/peak out around 9k rpm?

I'm just curious.....

You have to find a cylinder head and intake that will support that first.

It's just theoretical question...

I didn't think it was even possible, but I guess it is since you guys are asking for details on it.

My thoughts on it Solid Roller, long duration vs shorter lift, tight LSA.

He is not building the motor... I think he is asking this question to determine what makes a cam peak when it does, at least thats what hope he wants to know.

Like he said its theoretical, not realisitc.

ohhhhh......so bench racing...... (j/k)


cam isn't the only thing that makes an engine peak at a given RPM.....


I always wondered what a car would be like if you could combine the launching capabilities of a full on drag car (5000HP+ big block) to get you moving with a jet car to push you the rest of the 1/4 mile......

FWIW, the VTEC aftermarket cams are reverse split with 102 - 108 LSA. Different displacement, etc. but that is one way to get an idea.

correct, and use 235cc runner heads, and use 200# valve springs with flat tappets and use steel rods. It can be done as long as the wallet is there.

Yeah...no way I got that much money to blow on a motor I can't even really enjoy...

With all variable in place, what kind of cam?

I think I'll need to get myself one of those Harrop ITBs to decorate my room though...looks so pretty.

I know it's probably got a 1" stroke.....but it's still cool.

"Formula One will switch to 2.4 liter V8 engines in 2006. Cosworth has already begun dyno testing it’s V8 engine. The engine revs all the way up to 20,000rpm where the electronic rev limiter kicks in."

Renault has an F1 engine that goes to 28,000.

The stock pcm on these car does not go past 8,000 or so. So you would need a special computer.
