Yo,
i have a stock JDM h22a i bought stage 2 cams for it and supertech valve springs but i dont have the compression to make the cams wake up in my mid range like my stock ones did, so i rev it higher to make the power back.

My question is will i be safe reving my car to 7800-8000rpm's?

Because im worried about spining a bearing and cracking a sleeve, should i be worried about this?

 

revving that high is never a good idea, i don't think. i never go above 6000 just to be safe.

Nope

Stock bottom H22 have been pushed a good bit farther than 8000rpm. Rev as far as powerband dictates...

6000 rpms? lol seriously? thats not even close to redline. honda put redline at 7400 for a reason its safe to that point. trust honda

 

lol I take my car deep into the 7000's, I don't know where exactly. The real question is, where's the best point for me to shift? I land in Vtec everytime at that point.

I shift at 8400 with stock valvetrain. I plan on going to 9k with my new valvetrain and wont have problems..

 

I take my h23 vtec motor to 8k everyday all day no issues

 

what h23 do you have?

 

the accord euro r its a h23a vtec. comes vtec stock

HA! What a waste of a VTEC engine. I saw a post by Blake once that said that 8000 rpm on the tach is actually only 7700 rpm. I know that the higher the rpms go on the tach, the more distortion there is in the reading, so it makes sense. You can go past redline. That's why there is a fuel cut-off. You don't want to hit that too often though.

 

my jdm h22 smacks the rev limiter at 8200, is completely stock and gets taken there on a normal basis-

if you have an h22, ive read many times that you dont make power past around 8k so thats useless, someone correct me if im wrong.

 

lets see....he's got upgraded valvetrain and cams....so you're corrected. he CAN make power after 8k. a stock h22, on the other hand, cannot

lets see....your a d-bag cause he was talkin about the person he quoted, who has a stock valvetrain, and not the OP.

It's actually more like 7 grand for stock H22s, the only benefit to reving higher with stock valvetrain is landing in teh V-ATTACK

EDIT: Also, none of you guys are really reving past 7400 unless you moved up the fuel cut with some sort of engine management. JDM, USDM, BLAHDM, it doesn't matter, the H22's fuel cut is 7400, regardless of what that little lying son of a bitch tach is trying to tell you.

 

ah okay. gotchya

 

my ecu is chipped so no speed limited and moved the rev-

 

rabble rabble rabble

 

I wouldnt waste take the rpm that high unless you have some type of EMS, also taking the rpm higher does help sometimes depending on the gear you're in and also it is helpful through corners and such.
