I forget, which is better (for the engine) to cut, spark or fuel?
The MSD type rev limiters just cut spark, right? As I recall, that's a
no-no with nitrous?
I'm still mulling over the ideas in my head, but the basic plan I
have for my nitrous system is that the nitrous will only operate within
a certain window. Only at WOT, and only between 3000-5000rpm (or whatever).
That way, if you miss a shift, the nitrous will be shut off about 1300 RPM
before the Mopar rev limiter kicks in. So, if you do miss a shift on
the juice, it'll be shut off anyway at 5000, and then you've just got
a normally aspirated engine when the motor hits the limiter at 6300.
I think that should work? I'm planning on using either the Jacobs
Nitrous Mastermind or one of MSD's "rpm window" switches with plug-in
modules for this.
