Looking for advise.

[493 Mike]

I have 2 rev limiters on my 540 engine, fuel and ignition. Should I use one or the other, both, or both staggered (different limits)? Thanks for your time.

I exclusively use an ignition rev limiter on all our race cars.

Low side is for staging the car on the trans brake

Ah, I meant 2 ign limiters.
Not sure why to use the fuel limiter

Last thing I'd want to limit with an active ignition system is fuel. Lean ain't good....

 

[GTX JOHN]

I run 3 steps: one for Brake/one for burn out/one for high side.

Ignition.......

If you want to run both, I'd make sure to kill the ignition BEFORE the fuel shut off.

Kill the fire before the petrol.
