I might "have to" run the 150 or 175 shot on my motor this friday .. i usually run it on 94 pump gas .. i made 480 rwhp on 94 octane and 100 shot .. if that doesnt get me in the 10s imma have to up my shot .. just wondering how much race gas and what octane should i mix with say 1/2 or 1/4 of 94 octane ?!

is 103 unleaded good enough or should i go all out and put C16 in there ?!

 

I ran mine with 175 shot, 11:1 compression, and about 96 octane (101+91)/2. No detonation at that level. So I guess that's what my recommendation would be.

Good luck on the 10's...

I add 5 gals of Sunoco 104 unleaded when I go to the track. Tank might have about 2 gals of 93 in it + the 5 gals of 104. 150-175 shot NX with no timing removed. No probs so far.
