rev limiter?

[b8er]

just curious if it would be possibe to build your own rev limiter, just thought it would be neat to have, dont really need it but whatever, i dont know much about the whole eletrical aspect of the ignition and what not, like i know the basics but just curiouis if it could be done and if so what you need for it to work and what you need to do, thanx for any info

Well for about $130 you could have a crane ignition system with a built in rev limiter. That seems to be a little more effective and time saving than building just a limiter.

[b8er]

yea iv knowen that i was just wondering if it was possibly and what had to be done, has anybody ever tried?

[ACCORD EX]

does anybody know the concept of rev limiter ?? does it cut off ignition or fuel or what ?

[Mike's89AccordLX]

I would assume ignition since mine is with the ignition system and is wired in with the distributor and ignition coil.

[HondaBoy]

it cuts out your ignition power at a certain set rpm. as far as i know my car doesnt have one. i've taken it way over the red line. not really that good to do. i saw those MSD ignition boxes that you can set the rev limit. those are probley about the same price as the crane one, but more available.

[Mike's89AccordLX]

MSD isn't as good as people assume. Go digital or go home I have a digital crane system and it's about 1/3 of the size of one of those big analog msd boxes.

[HondaBoy]

is the MSD box some type of mechanical system? i dont know what goes into it. how much smaller is this Crane box? post a pic. that'd be nice to see. not sure what one you have.

[Mike's89AccordLX]

I have the Crane Hi-6S Fireball digital ignition system. I don't have a pic of it but you can find it at summitracing here:

Click the fitment tab to see what the dimensions are of it.


MSD boxes:

(this one is somewhat comparable except that it isn't digital and you can't set the rev limiter the same as mine)

With the MSD ones you need those plugs or pills to set your rev limiter. With the crane one I have you just get a little flat head screw driver or a car key and turn 2 dials to set it. Very easy and the crane one has the ability to have optional accessories such as the timing advance/retard controler that you can install inside the car so you can adjust the timing from your seat

thanxs for that info mike but does anybody know how it actually works like how does it curt the spark and whatnot, is it even possible to build your own?

[shepherd79]

it is possible to build your rev limiter.
the way it works. when the engine gets to sertain RPM range, it will cut the spark.
on the other side, you can have or actual we have fuel cut off. when your reach red line, the fuel will stop flowing.

[b8er]

ok, now what would be needed to build your own, has anybody done this, what does it take to do?

[A20A1]

I believe it is more complex that just dropping spark... didn't MSD mention droping the spark in a certain sequence. so you don't just drop spark in one cylinder more than once per cycle. it alternates... or something.

I wish I knew how I could use the 4th gen distributor with carburetor... cause I found some nice upgrades for the 4g distributor.

[ACCORD EX]

i think cutting off the fuel is easier than playing with sparks !

Mike !

[Oldblueaccord]

The only downside to cutting fuel is its leaning out the motor since there's still spark but little or no fuel.

On FI models,fuel cut, I think its 7200RPM might be 7400 I havent checked lately.

[modu03]

why would you want a rev limiter anyway... there's already one on the accords... somewhere around 7500 is when mine kicks in. i felt the need to test it once. anyway, with a decent cam, you should get good power pretty close up to that cut off point.

so, why would you want to make a lower limiter?

[Mike's89AccordLX]

Um we don't have a rev limiter. A20A1 ran his automatic to 8k rpms on a video. Maybe your car just dies at 7500. Not sure why you feel the need to rev it that high anyways. The car runs best at like 5k or 5.5k. I have my limiter set at 6500 rpms.

[bobafett]

mike FI cars have a limiter from all that i have gathered ,but carbed accords dont. ive never hit mine, so i cant verify this...

[Mike's89AccordLX]

Oh yeah Mike and I are the lucky carbed guys.

[A20A1]

we have a fuel cut... but I disabled mine.

[Mike's89AccordLX]

Mind letting us know how to do that Mike? And this wouldn't put any accidents or fatalities responsible by you. Just thought I would throw out a disclaimer for ya

[b8er]

so your saying the accords come with a stock rev limiter? at 7500? just curious if it would be safe to take a stock engine that high? i got an 87 EX-i with like 262???km on it, would i ever wanna take it that high?

[Oldblueaccord]

I have an occasional brain fart and go from 4 to 3 instead of 5 so I test it out about once a year. I dont think our motors make power past 6k rpm so your just wasting time. Ill pull first gear to 7k and then shift thru 6200k drag racing once in a while. I prolly redline my car at least once every few days and its got about 253k miles on it. Honda makes good motors they can handle it.

if you engine has 262 km on it, it sounds like it is brand new engine. you need to break it in first for the first 1000km. after that you should change the oil and you are ready to take it up to redline. i wouldn't go past red line, because you will have a good chance of burning the headgasket. it happened to me. i blew the headgasket between cylinders 3 and 4. it was a straight shot. nothing got damaged, but it put my car down for about a week untill i got enough money to get it fixed.
so, don't take it past redline. the stock cam won't make power past 5500-5700 rpm anyway.

[b8er]

ok thanks for the info, ahaha my car has more then 262km on it, i got 262 thousand and some odd km ut thanxs for the info non the less
