I want to know, when picking the right race fuel (which I've never bought before), is this one of those times I should be following the labels exactly for my particular engine, or do I just buy the highest octane one they have for maximum performance?
Now, I have a fresh 440 +30 in a 73 Duster, somewhere between 9:1 and 9.5:1 comp, ported 902 heads, very nice flowing custom hooker exhaust, torker 2 intake, weiand 1" spacer, holley 850 double pumper, turbo action 3500 stall, 30in tall street slicks, 3.93 diff. It's making around 460hp in the higher rpm range, I dont know exactly where I've never dyno'd it, the power is just a guess but I know Im close...
I run pump gas. I want to see what happens with some leaded racing fuel, and sunoco is the brand I looked up and they sell it in Auburn supposedly so Im gonna go get some. According to their chart, their basic PURPLE 110 octane standard fuel would be what I should get, but I want to know, would it be a bad idea to try out the 116 octane RED maximal??
Im not totally clueless, I did read that the Maximal's description, it's for engines up to 17:1 compression and 10,000 rpm, but from lack of experience, I dont know the answer here, IS THIS ONE OF THOSE "BIGGER IS BETTER" SITUATIONS? Should I stick with the recommended fuel, or get the top level fuel?
