hey i got a 98 prelude sh would it hurt my prelude if i go past the redline like at 7800 rpm cuz my redline is 7400 rpm and my rev limter is 8000 rpm? thanks

 

i wouldn't rev a stock H22 past 7400. They are already not meant to be revved high and on the stock valvetrain thats just asking for disaster. Besides your only losing power going past that 7400 mark on your stock cams.

 

thanks for a advice NCSTIdriver i appreciate it

 

I disagree. You might be loosing power but you'll fall into a more powerful section of the power band

 

Agreed. I had my redline raised to 8100, rarely took it there, usually stopped about 7800, but it did help me stay in VTEC when shifting from 1st to 2nd. The only problem I had was that stupid auto tensioner finally crapped out on me. Luckily, no bent valves.

 

If you sill have your rev limiter unmodified then, YES REV THAT SUCKER WAY INTO RED LINE. Your stock tack reads too high when accelerating fast, I know on my car the stock tack will read 8K+ but the true ECU signal of engine speed is still only 7200. If you shift around 8K then you will have no problem staying in VTEC. Don't believe your stock tack, if you shift at it's red line your actually shifting too soon, just rev it till you hit the limiter or about 8K on it.

 

revv it till the bitch shoot flames.....

oh wait, mines prolly the only one that does that

my h22a i had in my accord would shoot flames on the 1-2 shift

 

Shifting past redline only seems to be helpful during the 1-2 shift.

12 year old Vtec H22A. No rebuild ever done. 8,000 rpm daily.

These engines were meant to be punished IMHO.

lol. are you guys sure i wont *** anything up buy reving it to 8000 rpm i just bought the car and i dont to fu*k anything up cuz i got no money after buying the car

 

ok with all my clutch problems ive been having to work out (witch i have)

stock tach will be off 2 to 400 rpm easily....my vafc has recorder way to many 8500 rpm miss shifts ....it makes a horrid sound but i can honestly say its been a goo 10 or more time this has happened as well as a 3rd to 2nd while racing ...mabye im lucky ..mabye thats why my car only runs 15.0 lol but compression is still good and it starts great sooo i would say go ahead and take it up but like somone said its only good on the 1-2 shift

after that shift when the power falls off...you can feel it ....i end up shifting ant lik 7000 to 7200 somtimes.....and my motor is stock except for the basics

well first off it doesnt hurt it to go to 8k...if it did honda would have the militer at 7400, secondly, the motor can make good power above 7400 even with stock cams, mine dynoed with the max power being at 7550...and the advantage to going higher in the revs, is to land higher in the revs thus making more power, also the ECU has alot to do with where it makes power as well...in any event your fine to rev that high, and for the record ive hit 9100 a few times only cuz my rev limit is that high, never had it adjusted..and mines fine, also hit 8500 to 8700 on burnouts...never had a problem, 2 years now and still perfectly good compression the h22 valvetrain is stronger than some think....also if u dont rev out to 7800 to 8k your not going to run very good times, been proven

read my post on up there, 8K on the stock tack is not 8K! Rev that sucker up there, the car will NOT let your over rev it anyway. It has a rev limiter in it. You will know when you hit the rev limiter, and nothing bad will happen. I have hit that limmiter many times.

 

The guy I worked with and his old friend tried to kill a 92 civic DX's engine before the threw the B16 in... they had to bounce if off the rev-limiter for over an hour before it shut down. To kill it completely they fired it back up and fed the coolent hose into the intake, but it still took another 10 minutes before it shot a rod

I bounce it off the rev limiter all the time. The car has never even hiccupped. If I can do it to mine, you can do it to yours.

it has a lot to do with the extra heat that the turno produce and the added fuel... i'm running 780cc injectors, it dumps mad fuel, so flames happen

so does that mean if ur just running really rich with a turbo u can throw flames?
does the exhaust matter? i have no cat but do have a resinator, would it still shoot?
ive hear some people say u have to beat the **** out of ur car to get it hot enough for that to happen? i am boosted btw. j/w if mine can do it. (6psi) inline fuel pump, stock injectors, would i just need more fuel for it to happen?
