I was wondering if anyone would have an idea of an air/fuel mixture for nitrous....

My compression is going to be anywhere from 11.0-11.5 with a 100 to 150 shot of nitrous...

any info would help out a lot...

 

I would go to the dyno for a baseline tune up for the motor only. Let say your motor runs good somewhere in the 12.1 to 12.5 range. Then do the nitrous tune at the track. Get your nitrous tune happy in the the 900 to 1000 bottle pressure range. keep your bottle pressure consistant and play with fuel jets. All nitrous cars run great in the 1/8 the tune up happens on the big end of the track.
My crx is 2000lbs runs 13.5 0n the motor and 11.60 @ 116 on an 80 shot. I know that nitrous tune was about as good as it gets.Goodluck

 

Whenever we're working with tuning that much nitrous I always tune a little richer than with standard FI setups. 10.5-11.0:1 is my norm, but the big thing to watch is your timing. Read your plugs between pulls when you start tuning your power curve!
