Redline on the 24V Motor

Since I added the Smarty, Edge and straight piped the 4" exhaust I love to rev. the motor at home, smoke a bit and have some fun. I was wondering if the 24V motor will automatically de-fuel before exceeding the redline on RPMs? Or when we do the "snap test" for emmisions we are supposed to give it full throttle a few times. Can we hurt anything if we rev. the motor too high (in N of course)? Or does the rev. limiter prevent over reving the motor?

Just curious.

Thanks !

Tom

I understand the rev limiter will stop the RPM's but a stock 24v shouldn't rev any farther than 4000 RPM anyways. The only time you can override the rev limiter is coming down a hill with and allowing the RPM's to exceed the red line.

Thanks!!!

With that being said I need to get the valves done...I am at 122k now with no valve adjustment yet.

So I guess it's o.k. to rev. up to the redline sometime I guess?

Does WA State do emissions on diesels? TX and AZ don't.

Correct me if I am wrong, but won't a stock truck de-fuel and/or cut off when you hit 3200 rpm? I just had an experience last week where I got to about 3200 while in second gear and when I went to shift to 3rd and push the go pedal nothing happened. The truck had died. I pulled over, looked everything over, switched the fuel relay in the fuse block and turn the key back on and fired up. Hasn't missed a beat since. I have since switched the relays back to original position and still running fine. Do I have something else going on here? If so, I will start another post, but that is my experience.

It sounds like your experiencing what I've hear about, where the VP literally runs out of fuel because of your aggressive fuel box. At least that why guys think its happening since there's nothing else to point to, and it only happens to guys with those boxes. I've read some threads regarding but maybe you'll want see what you can find out.

Yes WA does emissions on diesels. I had to do it last year on my truck.
