I went to the track last night. I only got to run once. I had a shitty launch and wasnt used to the high reving all the way yet. I pulled a 15.5. at 88 mph in my 4dr. I was wondering if you guys shift into 4 or let 3rd gear ride out till end. I think are 3rd gear goes to about 92 mph. I was hoping to get 15 flats. I realized after the slow time i was shifting at 7000 in every gear. Next time im gonna hit 7500 every gear.

 

Do u have american spec or jspec swap? I have jspec and run mine safely to 8k, rev limiter is at 8250. Ive had no complications with my motor from running this high, and it keeps me up in VTEC even between shifts. I have the swap in a coupe, and when i last ran i was on 17s with swap, factory JDM LSD, intake, header and exhaust, and ran a 14.60. Depending what ur setup is 15 flat should come no sweat

 

You should up to almost 8000 rpms. Let it run all the way through third if you can.

 

you can ride 3rd gear out to like mid 90s mph, so unless your way into the 14s, u should beable to just ride 3rd gear through the trap. And shift as close to fuel cut as you can w/o hitting it of course. And lastly fuel cut is at 7700rpm on the P13 ecus, but keep in mind your stock tach is pretty off so it can vary what the tach displays.

i wouldn't do this if i were you...the h22 is notorious for a shitty oil pump and at that high of rpm's, it could go kabooom real fast...

Not true. It is not designed to rev that high. It makes it's peak HP at 6800rpms so it is not supposed to rev much higher. No reason to since it isn't making anymore power.

 

you quoted the wrong thread

Actually, I did not. You said that the oil pump is shitty in the h22. It is not. I have never heard this in all my years of Honda tuning. If you are saying that the oil pump fails when you rev the motor over 8K on a regular basis...then yes, I agree with you...if that is how you define "shitty oil pump". But I do not define something as shitty when you do not use it the way it was designed to be used.

Again, the H22 was NOT designed to rev much higher than 7500rpms. People expect much more out of the motor and that is why the parts fail. Drive the H22 the way it was designed...and you will not have any problems.

S2000 and Type R motors can rev higher. That does not mean all Honda motors can be driven that way.

I am not busting your chops. Just clarifying. I don't like to see the spread of misinformation. If you can prove me wrong...with a legitimate source that would be great. I am not saying I am all knowing. I am here to learn too.

 

I have found many cases over the years of the h22 oil pump going out, one recently...here's a link:

read the entire thread...as you can see, it is common knowledge by many people that the h22 oil pump is prone to failure...

 

ok kool thanks for all the replys. Im just gonna be safe and keep my rev limiter the same. Im gonna rev to 7500 next time and hold 3rd then i should be able to hit 15 flats

 

It's entirely poss my Tach is off, im going on info given to me by the guy who swapped me, who is Honda certified, after he did it he told me i could safely go to 8k by my tach, which if it is off would explain the discrepancy, and to avoid hittin rev limiter, which in my case kicks at about 8200 on my tach. The motor has run like clockwork for over a year now, so I'm gonna stick with what I'm doin

 

yes the accord tach is off...my datalogger reading off the ecu was at 7400 when my dash tach was at 8100....

 

my stock tach was within 50 rpm (fifty) and the speedometer was off 1 mph at 125 mph.......they aren't all off as bad as people think.....

 

there aren't 50 rpm incriments...????

 

sure aren't........what's half of 100? 50...halfway between two marks, but it doesn't matter.......it showed 7452 and my tach showed 7500rpm

 

Also remember fellas the Hs eries crappy bore/stroke ratios, couple of H22.s have gone kaboom cause of that or lack of oil feeding.

 

back to the topic he asked....I ran a 14.5@95 when my 4-door h22 accord was all motor, its an usdm motor shifting at 7,500rpms...get some pratice, u can do better!

 

yea i think i should be able to hit 15.0 with my best drving.
