Favorite Race fuel

[tinman800]

Probably been discussed before but here goes.
What is your preference for race fuel brand. Seems like everyone has a favorite and one or two they hate.
I've run primarily Sunoco and haven't notice any big issues. Also have run Rocket brand race fuel, F&L, and VP.
Had a guy tell me the other day Sunoco was the worst he had ever tried.

On another note, at what boost level is it advisable to intercool the intake charge?

Av gas is my favorite race fuel until it won't support the boost levels any further. Then on too Sunoco 110. Or vp.
Played with Elf awhile back in the bikes. It was cool stuff. But in my opinion there is absolutely nothing wrong with properly stored vp or Sunoco.

On the inter cooling front it's more a matter of at what point charge temps begin to fluctuate enough to cause issues with tuning. At that point I switch to intercooling but it's different on every turbo package.

I run Trick with no issues.

For trail use. V p 98 L.
av gas

My race sleds. V c 14 thru 25 psi
Vp c 23 for 25 to 42 psi.

hard to get av. gas in new hampshire.
98 L is very very similar with more lead and better rvp.

Vp c23 here. So far very easy to start and tune up to 24 psi and ~ 700hp. As Gus said c14 works great I to the mid twenties. We want as much deto protection as possible in our application.
