Compression Ratio and N20

Okay here is what i want to know.....how does compression play into the use of N20?

I am planning on building a 2.2OHV Cavalier engine for my cavy. I was planning on running a 10:1 ratio. And a 100 shot. It will have JE forged pistons/Rings, Eagle H-beam rods, and i was wondering you think i'll need a forged crank?? or will the stock one hold????

So would a 10:1 ratio work with that 100 shot? and am i going to have to run racing ruel. Because i don't want to just have to re-tard timing and lose my compression either.

So will it work??

10:1 compression and nitrous is fine. Just make sure you're getting enough fuel to support the nitrous. 2-4 degrees of spark retard probably wouldn't hurt. I'd be more worried about a stock Cavalier crank handling any kind of decent horsepower.

Is the Cavalier head iron or aluminum?

I'm pretty sure it's aluminum.

I say up the compression. But thats just a evil guy that likes to push boundarys talking.
