Re: Driveability of high compression cars
 

Jack, Why don't you mix it with 93 octane. You don't need 110 octane. Its not a race car is it?

I have tried various additives etc. with marginal success. Most of them help slightly, and in a pinch you can add some and get to where you are going, driving carefully. If you want to tune and time a hi-compression car correctly, you have to buy race fuel. The engine will run stronger and cooler, not to mention the grin on your face will be bigger. Buy a 55 gal. drum and use all summer.

Mix Turbo Blue or any other race fuel 110-112 with 93 and just keep your foot out of it or listen to your engine when you do put your foot in it..

Where do you guys get your race fuel? Do you drive the car to the track periodically or is there another way to get it?

I don't know about every track but most tracks here in Arizona won't let you fuel directly into a street car. have to purchase fuel in a gas can then you can do what you want with it.. sounds like the feds to me but can't vouch for any other tracks.. https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Farm and home right up the road from me. They carry VP. 5.00 a gallon. Alot of the S/G guys use it.

I buy Torco race fuel (110 octane) in 55 gal. drums from a supplier in town. You can do a dealer search on various fuel sites to find someone near you. Best bet is ask around at local cruises, shoews etc. You're bound tyo find people buying race fuel. Try mixing in different ratios until you have eliminated detonation.

Since 1997 we've put about 28K miles on our L78 Chevelle. It works fine on 91-93 octane gas. You have to get the advance curve set up right with no more than 34 degrees total. We have a 10.25-1 455 in our '72 Lemans Sport and it works fine too on the same gas. Running slightly rich helps as does a colder thermostat. Block off the heat cross over in the intake as well. It's the little stuff that makes things work. Stock engines can be as much as a point blow what is advertised. If you have a blueprinted engine that is a true 11-1, things could be a little more difficult.

Just buy the additive. It works good! If you got that much detontation something else may be wrong. https://www.yenko.net/ubbthreads/imag...ins/3gears.gif
