Race-gas
I called them yesterday and had a long and educating conversation with one of the owners named Mark. He said they are making good numbers on the dyno on 11:1 to 12:1 compression engines using just 4 ounces to a gallon. They dyno test this stuff and race with it so they have tons of experience and have gone through many blends before they landed on this one.
The mixing chart they show is not correct as they have been testing since they posted that.
The reason they invented it was due to inconsistencies of the octane in VP, Sunoco, etc race fuel. They were damaging their race engines so they said enough there has to be a better way.
No lead yet but not needed if you have hardened seats. Like the man earlier said. The bonus is being able to always have race gas available to you. I like to take my fat fish on long drives but always had to limit myself due to not being able nor wanting to carry 5 gallon cans of fuel in my car.
It only takes $3.75 (4 oz) worth of this to $3.50 (1 gal) worth of 91 octane to get 100+ octane fuel. That's $7.25/gallon which is cheaper than VP around here. Those are the words of their chemist not mine.
So I bought some and I will use my fatty as the test mule. I think what they have is what I have been looking for and I'm sure there are others here that will feel the same way.
As for the "build your engine to run on pump gas/ethanol" crowd....it's a little late for those wise words but thanks for the advise.....for the next engine that is.
