Does such a beast exist? I seriously need to talk to some nascar guys

But really, solid roller is a given, but do springs heavy enough exist? what about pushrods?

Jesel shaft mout rockers are most likely going on it, is this a good choice? anything better?

 

the real question is what do you need with a 9,000 rpm engine?

 

Hmm, 9k?

Solid roller cam, PSI springs, titanium valves with bead lock grooves, Manley super 7 locks, lightweight scalloped titanium retainers, Manton taper length pushrods.... yeah, it's all been done before.

I'll bet some modded LS7s will get there. I can't wait to see solid roller setups on them.

 

But, yeah, why 9k rpm ? Unless your engine is going to flow that much air and make power that high, it's kind of pointless. Higher RPM doesn't mean more HP.

I can get pretty much anything from a NASCAR car, I've actually got a set of PSI valve springs sitting here rated for 10k rpm and change.

If you want to rev to 9k, buy a Honda S2000.

 

Thank you sir. Pretty much what I was expecting, just needed to know if it was capable of that.




We should talk




And for everybody else out there, I'm not going to be making HP at 9k rpm, most likely around 7500-8K I know that sounds rediculous but I'm using a 3" crank let's put it that way

Again, this motor may be a pooch, but there's only one way to find out.

 

When that little needle on the tach says 9,600 RPMs....thats bad.

 

or an rx8, but thats not really fast

 

hahaha, or REALLY good if you want it to be


BTW. Just so you guys know, and don't think I'm an idiot, or you may still. I'm building a G-machine sort of car, a canyon runner, don't care about 1/4 mile like 99% of the people on this board do. That's why people are so quick to disreguard ANYTHING that will slow you down in the 1/4. I'm going to build a destroked LT1 (may still go with a normal SBC and carb due to ECU and injection issues) for a screamer making peak HP at around 8K rpms.

*puts on flamesuit*

 

What kind of heads are you lookin at using?

 

Just what I wuz thinkin'. If this is a serious question, you really better think long and hard about the heads. And budget $5,000+ for heads and intake plus another $2-3K for the valvetrain. You will need the lightest, strongest, and most expensive parts available.

Care to share what you have in mind, and why? I especially suggest LIGHT valves, probably Ti as Mr. Mindgame suggested. You are also going to need LIGHT and STRONG rods and LIGHT pistons. Oliver billet rods would be my choice.

Well, that's been a big issue, but I have a GREAT head guy, he takes a long time to finish, but he does gorgeous work. Also, honestly after thinking this through I'm most likely going to run a carb. The LT1 just has so many issues to get past to get the flow numbers I'm striving for, finding a forged 3" crank is going to be hard enough let alone a GenII, I don't really want to have to fuss with an ECU since I don't know what I'm doing with them past a hypertech and there's not a huge aftermarket for LT1 injection.

But in all seriousness it's going to be a G-machine canyon runner, a high rpm screamer with a smooth and gradual power band.





Different strokes for different folks. I like to be different, I don't like 1/4 mile racing.

 

wanting to build a high rpm engine is fine. but trying to build a 9k rpm engine for no real reason is stupid. If you were racing some specific class that you needed a small displacement high rpm engine then yeah, but sounds to me like you want to build a 9k engine just to say you have a 9k engine.

 

hell i would if i had the means
