That sounds about like what I can afford! Now in the event that I hit the lottery and can fill my bottle up and wanted to spray 175-250 shot what would you run? C12?

Thank you Gents!

The digital 6 would take care of the retard but should I still start at 36 with the better fuel? So for all the questions just trying to talk my self out of a $1200 dyno session.

You also want to make sure you have enough ring gap to tolerate the temperature and expansion so the ends of the rings don't touch.  You are also looking at building a real nitrous motor and not just a stout NA deal.  Rings and pistons need to be selected accordingly.

I would be running much better fuel for the nitrous side. JMO, I run c12 for both my motor and nitrous side if I had it my way, it would be c 16 for the nitrous R side, but it's off one fuel tank.  pull 10 degrees for a 28 20 jet set up. Also flowing 6 and a half pounds of fuel pressure. NGK -8 gapped at 24

Digital 6 will work just fine for a 200 shot. You really want to pull 2 degrees for every 50 hp shot of nitrous untill you get the tune good.

Awesome thanks for the info Gentlemen, the motor should be good to go as far as being bottle fed. Just need to dust off my memory as the last time I played with nitrous was about 15 years ago. That was the end of my license for some time..😜
