I was wondering how to eliminate the rev limiter on a 91 d15b2 dual port engine with out a mod chip

-thanks Oby

 

No, that is computer controlled, hence the chip to change the computer.

 

you have a rev limiter for a reason. usulay near max of what the engine can handle. why would you want to remove this? it will let you rev higher than your engine can handle and justblow it up. also if your stock reving does not mean faster. stock D serieswith 9,000 rpm is slower than D series with 6,000 rpm rev you run out of power

 

maybe he's trying to blow the engine..

 

i love these kind of guys. i whooped on a DC integra because he swore he could beat me just because he could rev his car to 9k. I kicked his *** by 3 cars and only revved to 6800. LMAO. He didnt quite understand that he wasnt making any power up there, but eh. i dont like street racing but i had to make an exception with this guy, found a backroad and spit all over his theory.

But go for it man, a dual point system is going to give you huge power up top man.

 

thanks for all of the feed back but I race my civic on a 1/3 mile dirt race track and the car hits the rev limiter a few seconds shorter than i want it to. All i need is 300-400 more rpm

You could just do an mpfi swap if your class would allow it extra HP and higher rev limit.

I'd try to contact drdisco69 for obd0 work.

You know you won't make power up there as stated. Dirt track racing that takes *****.

 

You could go for a bigger tire/wheel combo too. You'll effectively raise the final drive and still make power all the way.

 

why? can it even handle that high? it will float a valve

Head will take a few extra rpm like the 300-400 as asked for the OP.

Hes racing it so it'll not last for ever anyway. But the wear and tear from extra few rpm won't really greatly add to the shortness of the motors life span.
