Hate to hear you had a bad experience with it.

I thought i mixed it good enough........guess not! Lesson learned. LOL!
Actually with a roots blower you shouldn't need an power additive fuel....except for certain classes.

Well, the nitro-methane on-demand BOOST sounds risky for slug venting.

I'd use a vacuum switch that only applies nitro-methane while under load in "3rd gear", and perhaps reduce timing?

Vacuum switch probably good idea.
Timing not sure about.
Nitro may need more timing?

Forgot about this engine:

See Thru Engine



This is what you need to test your idea?
Maybe put a clear Pontiac head on and try it?
