Not to sound like a newbie, but I'm trying to determine fact from fiction.......What is the highest rpm that I can shift my internally stock 1994 jdm h22 at?

 

I wouldn't go past 8000, and that's pretty liberal.

 

when you feel/hear the valves floating stop accelrating

 

8000? I've never heard it that high.... the two that I was debating over was 7200 and 7600...... I have mis-shifted and reved up to about 7800 once, but even then it didnt sound right.

 

you will start to float valves and/or detonate around there

I would go 7000 to be safe

 

yea id say right before or right after red line

 

well, on my stock accord tachometer i shift pretty dam close to 8.

we all know how they are off. according to my v-afc the highest rpm it sees is ~7600rpm... this is with me taking it as close to 8 on the tach as i can bare.

if I take it too far, I bang the rev limiter, which is at about 7800rpm according to the v-afc once again.

 

an Jdm H22a would be 7,200-7,400 RPM's

please if you don't own an H22 Accord don't respond cause your most likely spreading wrong info.

generally 7,400 according to a VAFC is where you want to be. How that relates to your stock tach, you need to find out. for racing you'll need to shift high enough in the rpm range to land in VTEC on the 1-2 shift. w/out lowering VTEC on a VAFC this may mean 7,500-7,600 rpm shifting.

 

well on my 98 prelude type SH its has the stock h22a4 and it redlines at 7400 and the rev limiter kicks it at 8000 and i take to 7900 daily. i think you should be fine taking it to 8000

 

i shift at 7800 and have teh fuel cut set at 8200
i would not go beyond that on stock vavle train, but honda did use dual valve springs on the h22a for a reason.

 

i shift at 7700 right before it cuts off at 7800. did shift once at 8200 and it didnt sound too nice, wont be doing that anymore.

 

all of you guys claiming to rev to 7800 or 8200 on a stock ECU with an untouched rev limit are incorrect

the factory, OEM tach is inaccurate

the fuel cut on the regular h22a1, a4 or jdm h22a is 7650 TOPS
there is no H22a, even the SIR s-spec that is capable of revving over 8000rpms, the fuel cut on that motor is 7900

the stock tach reads higher than it actually is, a few hundred RPMs

 

in my case i am running a hondata s100 p28
i know for a fact the fuel cut is at 8200 since i know the guy that tuned it and it made enough power to make ti worth going that high, plus i use a shift light set at 7800 as well as an automete tadch since my car was not equiped with a tach.

 

when my valves hits the piston

 

i dont own a h22 but my friend has one in his accord and he told me to shift at 7800 when he let me drive it soo? i dunno it didnt make any wierd sounds but damn it was fun i want one for mine now

 

i never shifted past about 7400...makes funny noises if i shifted anywhere beyond that...i never did find the rev limiter, though i was using an auto ecu in a 5 speed...
