Safe compression ratio for N2O

[mikemustang289]

What would be the proper compression ratio for running a 75-100shot on a 302 staying with 91 octane. Is 9:1 ok?

I don't know what comp ratio would be good for N20, but I know that ~9 is ok for NO :smile:

Nitrous likes compression. I'd go 9.5-10:1 Hopefully more people will voice their opinion.

yes nitrous is the power adder that doesn't mind compression. run what you want just remember to take 2 degrees of timing out for every 50 hp shot of the juice.

You'll be fine. As stated, Nitrous doesn't care about compression.

umm..... what?

nitrous oxide is N2O... just so ya know.

91 octane .. is ok IF the timing and plug heat range is correct and the fuel pressure!! If it were me, and fuel is avaliable.. I would add a gallon to the tank to be safe(er) and run the piss out of it!! I feel being on the safe side is always better to make the second pass...??

Just me...........................
