H22a accord with a chipped p28, What's the redline

[NAiL05]

That does seem kinda low. At 4000RPM im around 100mph. I dunno id have to check on what im reading at 70mph but you could have an f22 tranny. If you have an LSD tranny look through the axle holes and you should be able to see all the way through. They should make LSD for the F22 Trannies. And no the ECU wouldnt effect the tranny unless it was auto. DO you have any check engine lights if you still dont feel or hear VTEC kick in since 6200 with no indication of VTEC is a lil high?

Well, I had just went to test it out, Vtec kick in at 5900. Try it 2nd and 3rd gear, both kicked at 5900, although it feels a bit slow from 5000 even when vtec kick in at 5900, i doesn't pull hard. I really haven't try it pass 6500, stop around 6400 since I'm not sure when to shift, maybe I'll try it at the stock redline(7200) to see if it pull faster beyond 6500. I also had tested my cousin's 92 integra ls vtec. He have a stock p72, I can feel vtec kick in at 4500 and it also pull alot harder once it hit 5500. There's no check engine light on my.

If i remember stock the VTEC on the prelude is suppose to kick in around 5600-5900 which is around where your at. As i mentioned i have a chippped P28 with a skunk2 chip. My VTEC is suppose to engage at 4500 and my rev limiter as mentioned was 9500. Whenever my VTEC kicks in since im still using stock tach it reads 5000 which tells me my tach is off or the chip lied to me. Since one of my buddies chipped it i know its suppose to engage at 4500. Well I would have to say in your case just shift up to 7200-7400 and see what happens.

umm VTEC on the H22 is supposed to kick in at 5200 rpm. thats what ive read! u say ur supposed to have YOUR VTEC engage at 4500 rpm but ur tach reads 5000 when u hear it? Id say then its kicking in at 5000 and ur so called chipped ecu isnt really chipped. unless ur tach isnt properly working ie. jumpy/stickin tach?? are you sure ur rev limiter is at 9500k? cuz umm thats insanely high and ridiculous! u should rev ur H up to 7800 and see if u hit the rev limiter......

A stock h22 doesnt make any additional power after about 7500 rpms, so all you are doing by revving any higher is making noise and decreasing your engine life.

*someone had a dyno sheet of this... dont feel like looking for it though.

Bingo. My JDM H22a stopped making power at about 7400 and started going back down around 7600. I, personally, shift @7200RPM by the stock CB7 tac, which is off at that range, it's proabbly closer to 7000 real RPMS. I wouldn't shift higher than 7500RPM (CB7 tac) or 7200 RPM (real), there's just no need. You'll end up spinning a rod bearing if you rev higher.

[rant]I never quite understood the rev as high as you can mentallity, I mean, I like higher revs personally, but...I dont go beyond factory limits...[/rant]

Thats what i do tempest also. Also SMs stock tachs are not always ACCURATE. This is why I only hang around the normal redline of the h22a. If the chip was advertised as engaging at 4500RPM and 9500 RPM Rev limiter then thats what im going to believe for now unless i can get some big ass tach from my friend and install it in my car temporarily to find out. I have taken the car all the way up to 8K once on the CB7 Tach to experiment and no im not going to "rev as high as i can" when i know the tolerances of my own motor.

[blazen_accord]

STock JDM H22 is rated 200@6800rpm, so with the factory tach is off by 100-200rpm higher. Shift at ~7200 rpm and you are in a safe zone redline if you want to be safe and engine lasting, any less rpm and you make less horse power and more and you risk throwing a rod. my vtec I hear kick in at 5800rpm and bounced my rev limiter at @7700rpm then again I have an Auto LSD

but a stock tach cant be off THAT much at the 4500-5000 range......definately not off 500 rpm in that range! so umm if its supposed to kick in at 4500 and you hear/feel it at 5000 then thats most likely when its engaging....thats all i was saying! tachs get inaccurate at later RPMs esp ours since our stock engines werent meant to rev in that range to begin with....

Damn Tom (Blazen.. it IS Tom, right? It's been a while man!), you just appear out of nowhere! I haven't seen you around here in a while! Nice to see you're still running strong with the H! Next meet we have down there, I expect to see you!

Anyway, you hit VTEC at 5800? Is that normal? I hit around 5200...

But I totally agree. With a stock H22 (stock internals and cams) 7200-7400 is safest. Shift so you hit the next gear JUST in VTEC and you should be fine. If you're running stock internals, stock cams, and tired stock valvesprings, you don't want to rev any higher than stock! If you upgrade your cams and springs, you could probably go to 8000 safely. Beyond that, be careful with your internals. That's still a 10 year old motor!

[h22sparkle]

damn yo deev is on the money and did you say meet where at???

[deevergote]

Nothing yet... but Tom was at the first CB7tuner meet I ever went to in MD... back when he had his kickass turbo motor (that sadly blew up shortly after). I haven't seen him since!

We need to get something going though... I have a cool idea brewing for some fun meets this year.

Whaz zup Dee , Yeah it's Tom it been a while I stop by here and there, I have to rely on my car to get to work so have not done much to it lately, still have my old turbo kit sitting in the basement Been neglecting the cb7 until some bastard broke in and jack all my electronic/gauges and stereo and subs so knock on wood get a dame alarm people..and install it not wait 1 year later like me so back to the cb7 scene now.

Like I say I "hear" my vtec kick in at 5800rpm oem tach, so it must have have engage at 5500rpm and with oem inaccurate by +-200rpm it dead on stock engagment point at 5200-5300rpm. I have a chiped P13 auto ECU so my rev and speed limiter is way up there if I am bold enough to rev past 8K,
WE really need a local meet going Dee I miss the one this last weekend due to install the AEM big rotor kit, man what a diff that thing stop like a truck and it still has stock caliber with SS line sorry ops for the jacked post..
