    Huh? I'm assuming you are talking thousands in regards to the RPM's. The D16Z6 motor redlines at 7, so that is probably why it falls off--you aren't creating any more power. If you are bringing your car to 9k, start looking for a new car now.

    or start looking for a new engine, if you've been revving to 9000 with a z6, because it wont last long with that abuse. There's a difference between hard driving and engine abuse/neglect.


    fuel pressure or dirty injectors could be at fault, but regardless the z6 engines top out their powerband around there s

    is it jerking or anything?

    the powerband of most engines tend to dropoff after they make peak power.. Some more steep than others. Look at some dyno charts of STOCK engines.

    that's why its called PEAK power. its not getting more powerful as you rev it higher, that's dependent on your cams and compression.

    The higher you rev an engine the more chance there is for the engine to mangle itself by having the pistons slam into the valves. The valvetrain gets overworked by unnecessary rpm and rpm that is higher than it was meant to handle. Hondas may be durable but at the same time they are as fragile as the next automakers engine.

    one more thing

    i assumed your engine was dohc.

    If is a sohc vtec engine, make sure your vtec switch is actuating, that may account for some droppoff.

    their redline is like 7200rpm

    D16Z6:
    125hp@6600
    106tq@5200

    The car stops making power at 6600 rpm's, There is no need to bring it over that.

    Single cam ZC's are more like the D16A6.

    Use Google. Get your answers from there.

    Maybe you will wreck this car, too, and then we won't have to answer the questions that you could answer by yourself.

    In how many of your posts did you mention you had a vtec ZC. Let me count--1. And at that, it wasn't until after all the other information I gave you.

    Give all the information if you want better answers. I linked you to reference stuff that was pertinent to the information given.

    You suck at life. Learn to do some research. A forum isn't designed to GIVE you the information, but to help you after you have found information on your own and still have problems.

    My answers are just fine. I don't give false information. The same GENERAL, PUBLIC INFORMATION that I have access to is available to you, too.

    You should turn emo and cut yourself til you die.

    Vtec ZC or not, you are going to blow your motor up if you keep rapping it out like that. But my answers aren't good, so I wouldn't expect you to listen to me. Just keep on trying to bring your motor to 9k...better yet, bring it to 10k. Maybe you will find the power up there.
