rev limiter help...again?

THRILLSEEKER · 07-22-2002, 10:34 AM

I installed my rev limiters last week and I am having some problems with them.

My engines normally run 5200 rpms@WOT after I put the 5000rpm chips in my rev limiters I can only get 4500rpms @WOT
Anybody have any ideas of what might be wrong?

I'm assuming they're MSD's. I've had some bleed problems where they start to mis-fire before the actual RPM setting.

Try a couple different 5000 chips. If that doesn't work, put some 5400's in it

Yes they are MSD on Thunderbolt 4 ignitions, I tried the 5800 chips and they only give me another hundred RPMS. I called tech support at MSD and they are stumped. I know that they are hooked up right, This kind of pisses me off because I paid a few hundred bucks for theese things and they dont even work right

You got me wondering why your rev limiter has chips in it. The one recommended to me from MSD for the t bolt 4 ignition system is part # 5468 and is adjusted with a control knob not chips. Do I have the wrong one ?

Hey Bo...what model is yours,also does it work like it should? I may have the wrong ones

I just got it and haven't installed it yet. I think i'm going to do a little more research on it first. Look on MSD"s web site. The one I bought is # 5468 and was recommended by their tech line. Let me know how you make out. Thanks.

Bo I tried all different chips I had from 5000rpms to 8000rpms and the dam things would still only give me 4500 Ime going to talk to a few more people and if I cant get them to work Ime going to send them back and try something else.
