What the best gasoline mix to use?

CSX 4039 You should have no problems getting way with just high test and a bottle or 2 of the octane booster. I have Aluminium motor, block and heads and 10.5 compression and run 91. If you are having problem with pinging, add a water injection kit from Snow. All you do is fill the tank with water and a bottle of windshield washer fluid. 50/50 mix. Works great for turbo and blower cars. You just run a little less timing in the motor. The motor runs cooler, and you only lose maybe 20HP inthe top end. Some people have said they have gotten up to 50HP more with running more timing. This will work on any motor. Just have to remember to fill the water tank. If you are at 11.0-1 you should be OK with a good carb and fuel system. Not letting the fuel get hot under the hood and on the way from the fuel cell to carb is important too. They sell hi temp hose covers to insulate your fuel lines and keep the temp down. Are you running a turnkey pan? The cool air from the outside of the car is better too. Try and seal the turnkeypan with form tape to the hood scoop. There is an issue with Aviation fuel. I believe it's a lubercate issue with either too much or too little. The other thing is you are not flying at 25,000 ft. If you are going to run in the 140mph range you will need a pilots license. Rick Lake Ps. Ennie is the one to ask about high compression motors and mixing gas everyday. He's been there and done that. He found out that in some cases less is more.

ron,

to answer you, yes octane supreme 130 is the product i use (religiously)
it is nothing more than a solution of suspended lead. this stuff works...period..

i see some of the other posts saying they add A COUPLE bottles of octane
booster. wow . to 16 gal i use 1\2 quart. so starting with 93 i end up
over 100. to address the pinging....detonation will only be heard as pinging
at the extreme of it..if you have a 10:1 motor or higher and you run pump
gas you are detonating....i have used racing fuel when i go to the track and i get the same results with the octane supreme. note the odor of your exhaust
when you run racing fuel......i get the same odor from my pump gas and the additive, not that this alone sells me but i equate this to having about the same blend. i have an 11:1 427 stroked to 468 stage 2 kc heads a 671 lift roller cam and 2 4 bbls i run 38 deg timing with an msd dist all my timing is in by 2000 rpm. i have trashed the plugs KC gave me with the motor ngk somethings i now run autolite racing plugs about 2 ranges cooler. with the additive you will need to read the plugs to see where your particular combo has its sweet spot....ok this is getting wordy

If you are "close" to detonation, this stuff really works. I posted the tech sheet also. My 418 ran just over 11:1 and needed it.

I recommend it.
