well your first problem is that the car will not make it a year (or likely even to 10 psi the first time) without Water injection or the legendary Anti-Detonation Device.

hey zero, i got the anti detonation device in my car and i run 19 psi on 93 octane, no kaboom, and no detonation. dave and skip say that 93 octane is good up to 20 psi safely. ill try it next season. By the end of next year im gonna try 25 psi on 100+ octane gas.

I put 100 octane from the Rebel Gas Station by my house...Ive even put jet fuel diluted with low octane gas in my car...100 octane is the highest I know that you can get here at a gas station only Rebel has it. The gas cost $3.59 a gallon 16 gallons to fill up. I paid $64.00 to fill up my tank...that was a night to remember too.

Jet fuel eh? From where , what brand. JP-8?

The jet fuel produced by a refinery may be all straight-run or hydroprocessed product, or it may be a blend of straight-run, hydroprocessed, and/or hydrocracked product. Small amounts of heavy gasoline components also may be added. Straight-run kerosene from low-sulfur crude oil may meet all the jet fuel specification properties. But straight-run kerosene is normally upgraded by Merox treating, clay treating, or hydrotreating before it can be sold as jet fuel.

The refiner really has only limited control over the detailed composition of the final jet fuel. It is determined primarily by the composition of the crude oil feed, which is usually selected based on considerations of availability and cost. And the chemical reactions that occur in the conversion processes are not specific enough to allow for much tailoring of the products. Yet, despite these limitations, refineries daily turn out large volumes of products that meet all specification requirements.

Regular Jet fuel is quite thick. Alot like diesel fuel. It requires very high combustion pressures. JP-8 will infact damage you engine.

So what did you dun in your car Vegas84RX7

thats cool! You should consider water injection. You would get the best of both worlds. Think about it.... the A.D.D. does somethings that the WI does (allows you to run more boost than you normally could)...Both WI and the ADD would allow you to run higher boost on 87 octain,etc...While the ADD admitedly will allow you to run even more extreme boost than the WI will (although Rice racing runs in the area of 22 PSI on 93 octain with WI)...The water injection will do something the ADD could never do. Lower your intake temps, EGT's and Engine Temps. The perfect package is not WI or ADD, its both of them together. I firmly believe that.

sorry to hijack the thread. BAD ZERO, BAD ZERO

You're kidding, right?

Go ahead and test it out and let us know what happens
