how much compression is too much?

I wish we could get Sunoco 110 at the pump around here, I have to drive 15 miles to the drag strip to get it.

RACE GAS | Racing Fuel Concentrate

Run this instead.

I have for over 5 years and thousands of miles on a big block, solid roller motor with 12:1 comp. I'm not easy on my car and I built it to drive so it gets it's fair share of abuse. When mixed, it's less expensive than Sunoco. Sunoco makes 106 octane (Sometimes) and Race-gas makes up to 107 octane (Consistently)

Race-Gas is more affordable? Looks like it!
Sunoco = $13.00/gallon ($65.00 for 5 gallon can)
Race-fuel = $8.00/gallon (6 ounces of RF ($5.63) mixed with 1 gallon of 93 octane pump fuel( $2.37/gal)) (A 32 oz can of Race-Fuel is $29.99)

It's awesome stuff and it works as advertised. I used to worry about how far I could drive my car, but now I can go cross country as I like.
If you don't believe me, feel free to call the guys at race-gas. They will talk your ear off and give you an education for free.

No I am not a paid spokesman, and no I do not get a discount for this review. :D

I've used it all from Sunoco to Av-gas and everything in between. This is the best stuff period. It always makes a consistent blend, and that's important.

Back to your regular program.......................
