On the site that I purchased my swap from it said that the redline was 7400rpm. TotalJdm says that it is 8200rpm. Other sites say 7600rpm. What is the redline for a 92-96 jdm h22? Sorry for the noob question.

 

Do you mean redline or rev limiter ?

 

Redline

I think redline is @ 7400 or even 7200. Now the rev limiter is a differnt story thats all that matter anyways

 

Ive just been revving to 7500-7600.

 

It's either 7200 or 7400. Either way if it's stock I'd keep it to 7200.

EXCELLENT reply!!

JDM redlines are 7400 rom too.

I rev to 7800 or 8200 depending which one of my ludes I drive. Stock bottom ends and one of them on N20 but what do I know

 

well whats done with them to require those extra revs, you cant say something like that without giving some details

And you can go ahead and give that advice if you'd like. Heck I regularly shift my stock head h22 @ 7600. Does that make it ok or safe or good for the motor?

Schmuck.

P.S. Are you using the stock tach when you shift @ 7800 or 8200? My stock tach is off 700rpm when it reads 8000.

 

Why are you f00's even bothering to shift that high? You do realize that 90% of H22's stop making power at around 7000-7200 rpms. All your doing is killing your 1/4 mile times shifting at 8200 unless your boosted or on the bottle which most of you probaly aren't. And don't tell me you shift that high cuz you fall out of vtec cuz if that's the case you should learn how to drive before you shift that high and blow your motor or miss a gear.

You guys get smarter each time. All motor, stock block, stock head.

 

hmmm looks like peak is @ 7550

Thanks for the dyno, I was wondering about that because I am about to put in a JDM h22

 

yeah but u have to go a lil above ur power band so u can drop back into it

great point. I shift at 8k on my stock tach, which is really 7400 for me. you're probably shifting lower than you think.

i shift when my stock tach reads about 7700 or around there, i try to look at my VAFC , because its much more accurate than the stock tach.. so ya, about 8 k on the stock tach, is about 74-7500 rpm..

You don't know what your talking about.

I shift at 8200-8300 on a stock internal H22 motor, see my sig and tell me it's slowing me down I wouldn't recommend this to anyone that is relying on there vehicle however if you want fast ET's you need to to keep the revs higher. I was struggling to dip in the 12's shifting at 7500.

I don't agree with you but I would like to hear your reasoning.

At 8000 RPM, you are essentially making the same power as you would at around 6400 rpm. The ONLY difference is that at 8000 you are increasing engine wear exponentially.

However, let's see what you have to say to back it up.

Think about it. When you only rev to 7K let's say for conversation and you grab 2nd and the rpms drop to 5K you don't have much power there. You would have more power if you rev to 8K and drop to 6K in second. It's all about momentum and keeping the car in the power band in the next gear. My ET's speak for themselves, don't you agree?

Well, now we agree on something!! We all know that the H22 makes peak tq at 5500 rpm. We all know that it makes peak hp at around 6800 rpm. When you shift where I say you should, you use more of the "power-making zone" of the motor. Between 5500 and 6800 rpm is where the motor is most efficient. When you shift where you say, you miss pretty much all of the "power-making zone". The motor is back into the the inefficient mode. You LOSE momentum by revving higher.

Here is an analogy for you. If you are riding a mountain bike, how do you shift through the gears?? Do you pedal until you realize you are no longer making power to shift into the next gear or do you pedal until you have to stand up and pedal as fast as you until you actually STOP making power?? You know....where you are standing there pedalling basically just spinning the crank and not going any faster. Do you understand what I am talking about??

You know what, I just thought about something. Has anyone ever went to the drag strip, shift to second where it drops back down around 5500 rpm to take advantage of the torque, then shift higher to take advantage of the hp power curve of third and fourth gear?

As for your ET, I can't say for sure. It all depends on your 60', temperature, as well as a few more factors during EACH run. Just like how dyno figures vary from day to day.

My dyno figues vary from day to day? Your a joke. Here is my post from several month ago. https://honda-tech.com/zerothread?id=1131655

Horsepower carries you down the track, not torque. I had my readline at 7500 for the first 10 runs or so and couldn't hit anything better than a 12.9 @105mph. After speaking with a few knowledgeable pros they all told me to rev higher, especially in 1st and 2nd. I did that and hit several 12.7's and 12.8's. All I care about is drag.....how much experience do you have at the 1320?

PS-I haven't forgotten about your shady *** selling practices either

I am a joke?? I am the one trying to have a civil discussion and you are the one getting upset.

It's spelled YOU'RE If you are going to attack a person, learn how to spell. HAHAHAHA

My shady practices?? Yeah, I am known to be shady around here. 42 Paypal points and a pretty impressive vouch thread. That's why I've only been here for over 2 years and actively give advice. Yup, that's shady.lol

Sounds like you are the joke. lol

its all good matt. some people like less power i guess.

basically andyd- would you rather, shift gears, and a)drop to 14xhp and 130 ft lbs, or b) revv a little higher and drop to 175hp with 150 ft lbs through each gear.

remember- a is for ***.
