10,000 RPM on H22

[Slava]

Saturday I pushed my H22 to 10,000RPM, the engine was hot, burned my clutch, and my flywheel is worped. I have no idea why and what is a good clutch to get and what is a good flywheel?
Oh and my driver side axel went out.

uhmm.. why?

[Slava]

Raced a stang in my prelude.

[THRICE]

You sell alot of stuff on here...hopefully the stuff you sell doesn't get treated like you treated that H22.

[fitchnpolo]

What kind of engine management are you running/

[Slava]

The stuff that I was selling was all the extra stuff that I don't need. And with the H22 I was told that 10,000 is possible as long as the fuel system is done, plus I had the engine built to 11.0:1 compresion.

[TedR719]

If you need a new clutch & flywheel Pm me for prices. I can get ACT and Exedy clutchs!

[THRICE]

so was the fuel system done when you decided to blow 10,000?

[Slava]

Greddy E-Manage

[Slava]

The engine is fine I think it's just the clutch and the flywheel that I went out as far as I can tell

[THRICE]

You better hope...if not you're going to have a pretty hefty bill.

[fitchnpolo]

I could be wrong, but I dont' beleieve emanage lets you override factory rev-limiter. Does it or did you override it some other way?

[Slava]

Got to Racing Trenz or go to www.JDMShit.com you can buy computer from them.

[Maverick]

So do you have the valve train to support 10,000 rpm's?

[Slava]

I have the Type S internals got them from Flashoptions.com and I got the head ported and polished at havana machine shop so I think I do.

[Brian]

Ok sp the answer is no then. Yes fuel is a factor, but that isn't what limits how high a vehicle can rev. It's the valvetrain. If your valvesprings and retainers can't take 10k (which they can not) then valves will float and hit the pistons. Now how do you know you went to 10k since the stock tach doesn't go nearly that high?

[Slava]

I got a Pivot 12,000 RPM with a shift light.

[SleeperZ]

I'd be interested in hearing what the bore/stroke is on that motor - and what kind of rods and pistons can take those stresses. No normal engine can withstand more than about 4400 ft/sec, that H22 must have titanium rods or something -that's usually what limits the redline on any engine once the valvetrain is modded to take it.

You sure you didn't set the tach for 6 cylinders or something?

[Slava]

All the internals are from type S motor, the compresion is 11.0:1.

[Brian]

A type S motor wont even begin to handle 10k rpm's....sorry

[Milo]

I got my S2000 up to 11,200 once:eek: It wasn't intentional though. I was getting on it and misshifted...oops. That's what it showed on my VAFC. Luckily no noticable damage was done.

[danegod]

11,200? ouch

[CSMsi311]

he sounds like an idiot

Yeah, i was going to get a pic of the vafc reading 11200 but like an idiot i shut off the car before i got a chance to take the pic

[Brian]

I did a 3-2 downshift at teh track in my civic SI once. Luckily I got the clutch in as the tach swung over around 10k. I was lucky it didn't blow.

The thing about this is the guy sounds like he intentionally ran the car up to 10k for several seconds.......sorry to say, but that could qualify as one of the dumbest things i've heard anyone ever do around here.

[danegod]

the only car i know of in my area that can run at 10k for a short time is a 69 chevy Z28. when draggin, he told me he drops the clutch at 10k

[gjcivic]

i got nothing....damn it

[CSMsi311]

this is how you do 10,000 rpm

[Slava]

I held 10,000 threw first and when I went to shift thats when my axle went out and it started clicking and that was. I'm taking the head off over the weeked to see what it did to the motor.

[stu]

You know you burn in hell for lying right? Just an FYI.

[rb20]

I may not have had as much experience as the next guy, but I do read alot on valve float, valves, springs, titanium retainers, camshafts and gears, Piston rods and rod bolts, pistons and rings, crankshafts, scrapers, gaskets....(I know I left alot of the head and block internals out but humor me). If you have type s internals which are I think good for 220 hp.... you've f----- up alot more than just your clutch, flywheel and axle! espeacially if your valvetrain is stock! (yes even type s)

[john]

Why (or better yet, how) in the world would you push that motor to 10k rpm?

The Emanage does fuel & timing curve management, but does nothing to raise the stock rev limiter. What have you done to bypass the rev limiter? Which injectors & fuel pump are you running?

Pushing a motor that hard without some pretty beefy valve springs/retainers/etc will cause valve float, which results in valves coming into contact with pistons.

11:1 compression has nothing to do with the ability of a motor to handle being spun up that high, IMNSHO.

The stock rev limiter is there to protect the motor from silly stuff like this. While it's theorically possible to spin a motor somewhat beyond the rev limiter w/o damage (I spun a DSM motor to over 9k rpm due to a 3-2 shift around 100 mph at the track, on a 7500 rpm rev limiter) and come away w/o damage, more often than not parts will need to be replaced.

IMNSHO, you are probably going to find some damage inside / under the head. Good luck.

[Slava]

I haven't taken the head off yet, and if you look on the type S guage cluster it shows that it could go up to 12,000 and not having the rev speed limiter I think it could of gotten higher then 10,000RPM but I'm not going to try it again.

[Mr. NoSkills]

just an FYI.
my buddy running the crower stage 3 race cams + valvetrain won't even fuck around with 10k on an h22, i don't think even those cams would make power up there, let alone stockers...
good luck though on the breakdown, maybe you got lucky and nothing major is jacked.

[Brian]

Just because the gauge cluster goes t0 12k doesn't mean your motor can. Can anyone else confirm that BTW? Why would the tach go to 12k, maybe 8 or 9k

[Cheio]

I thought the fuel cuts off when you go that high?

"I held 10,000 threw first "... thats what shifting is for...

[Slava]

Actually I was wrong it goes up to 11K and the redlike starts at 8500RPM thats what it looks like on the guage cluster.

[danegod]

so my gage cluster goes up to 8k and my motor stops reving at 6k. just cause it goes up that high, doesnt mean its spose to go that high. if i was to somehow bypass my rev limiter, and shoot up to 8,000 RPM, i would most likely blow my motor. the most i would probly be able to rev up to safely would be 7 grand. but im not even willing to rev that high. my brother has a F22 A1 in his car, and he dont go over 7,500 RPM. i think what you did was pretty stupid IMHO. i wouldnt never even try to get my motor reving that high unless i was VERY certain that it could do it.

[CSMsi311]

my boost gauge goes up to 20 psi. maybe i should boost 20 psi:rolleyes:

[Slava]

I'm not saying what I did was smart at the time I thought it could handel it but now I know that it wont handle it, and I know that I would never do it again no matter what I do to my engine.

[David]

im sorry, but your lying H22, you engine could not take that much abuse even with forged everything.

And since when have you known what you are talking about?

If thats the case..since I have no boost guage...I should be able to run as much boost as I want right?!? Hell..its already hitting 19.5psi...might as well go for 40! :)

well stu, i agree with him, him and i both have common sense lol

dum dum dum dum DUMB!!

[25vtec]

i dont know about you but i got a fully worked h23vtec or shall i say 25 vtec and im sure as hell never to go over 9000 rpm, dude its not meant to be unless you are a professional racer with tons of backing to get new motors, axles, clutches, flywheels...etc....question is, do have an aftermarket flywheel, an aftermarket clutch? and what modifications and fortifications have you done to be able to cruise to 10,000rpm in a 22?

[cherrybombcivic]

please let this thread die 25vtec.

[stu]

Yeah no shit, and all the other old posts you brought up.
