With only 92 octane I personally wouldn't spray on a 12.5:1 motor. Not on a 13:1 motor.

i could prolly go to 75 shot dry easily as long as its dry..wet dont like the idea of gas in my throttdle body and intake can result in fire...i need some comments guys!

11.0:1 is the highest CR I go with when running nitrous. Another thing you need to look at is how the Jun 3's will work in relation to the nitrous. As you know, with boost you are essentially blowing it out of the exhaust which leads me to believe you will do the same with the nitrous.

personally, I would not deal with the problems of unequal distribution of nitrous/fuel from using wet/dry shot on a motor that I spent good money on.

When it comes to having a reliable nitrous setup, I think dp is the only way to fly. Of course with dp, you can only go as low as an 80 shot.

When i hear 12.5:1 cr w/ jun 3's and nitrous i think the same thing. The 100 octane will help out a bit, but to be safe you need to pull a good amount of timing.

I think you have a little more homework to do as far as nitrous goes... A dirct port will provide 1 jet into each runner combining both fuel and nitrous giving the same amounts of fuel/nitrous per cylinder.

get rid of the dry nitrous kit. use a direct port kit, especially if you want to run high compression. run the high octane gas. pull out more timing than you need, just remember to start safe on the safe side. you can add timing back in gradually when you are tuning the nitrous. if you run jun 3's your going to need to tune them for nitrous and compromise some of the all motor power, you have to tune out the overlap caused by the high duration cams so you don't spray the nitrous out the exhaust and waist it.

i don't think high compression and nitrous is a bad idea, just as long as you know what you are getting into. start Conservative and make sure its tuned.

im not saying dont use the jun 3's. you need to use adjustable cam gears and adjust the cam overlap to take advantage of the nitrous.
