If I plan to squeeze Nos, will my CR matter? Does it need to be low CR like 9.6:1 or high as 11:1? Is there an ideal CR to go with or it doesn't matter? Also, what about the tranny? Will long gears differ from shorter gears with Nos applications? Thanks guys.

 

Compression ratio matters. If you're building your motor, I honestly don't know how high you'd want to go. Probably no more than 10:1 for a street car/daily driver if you want to be safe.

Gearing...short gears are always better.
