VP Racing Fuel any one ever tried it?

[kim]

Recently I've been think buying a 5 gallon drum of VP Racing Fuel Street Blaze 103. It suppose to be for Turbo cars it street legal for some states in the US.

Is this fuel okay to use? any harm to the car? Let me know if you guys have used this before.

Thanks

Don't bother. Go down to your local Sherwin Williams. Buy 5 gallons of toluene. Mix it with 10 Gallons of 91 octane pump gas. That will get you to 98 octane. If you're dead set on 103 octane then mix it with only 5 gallons of 91 octane. I personally think that 98 is going to be more than enough for you.

The reason that Toluene is a bettero solution than the racing fuel is that the racing fuel is probabally an oxygenated fuel. Toluene is an un-oxygenated petroleum distillate with an octane rating of 114. It has a higher density of "potential energy" than the VP Racing fuel, or regualar pump gas. This means, that if you compare a cubic centimeter of Toluene to a cubic centimeter or 87/89/91 octane pump gas, the toluene will release more energy when combusted. The same holds true for the VP Racing fuel you are looking at. The only drawback to the Toluene is that it has a very high specific heat. That means that it will absorb a great amount of energy before it will combust. So you can't just run straight Toluene in your gas tank as you would never get the car to start. It WOULD be OK, to run it in a fuel cell and maybe have a tank switch that would convert to the fuel cell once the car was up to NOT.

as a side note though, if you do choose to use toluene, be very careful as it is a pretty serious carcinogen

so no huffing the fumes!!! :p

Also make sure to add some marvel mystery oil to the tank as the toluene will remove some of the lubricating properties of the gas.

I have a 76 gas station with 100 unleaded and a Sunoco with GT plus 104 unleaded and 112 leaded right down the road from me It's nice living in a town noted for car racing!

Used VP 110 and Trick 110 in the past, both did the job. I'd get a drum with a couple people, that can be quite a bit of coin and fuel for one person. Don't rule out methanol/water injection

Quoting Corky Bell, author of 'Maximum Boost', "Water injection is just a bandaid fix for something that should have been done right the first time."

Anyone actually try the toluene mix in their car? I kind of want to do this but dont want to f up my motor or anything.

It won't hurt other than make the exhaust smell really weird

I tried to see if it would help when my KA was pinging since it only had 87 octane in it but it was no good, the motor was dying.. assuming it was ping..

have yet to tear it down mostly because I lack an impact gun sufficient to break free the overtorque (by previous owners?) flywheel bolts..

Great book, I just happen to disagree on that portion.

Consider this, Octane is the resistance to knock. That's all octane is. I doubt you are making enough power to see the limits of 91-93 octane (if tuned properly). If you are adding higher octane to fix a knock issue ( then 91-93), you are adding a band-aid to it.

Why do you disagree? I am curious.

[biosehnsucht]

Exactly. In a perfect world, in which detonation was never an issue, we would run 0 octane for the most performance.

'Poor' tuning or engine design leads to needing more octane for the same power, however depending on what is leading to the octane requirement it is often more realistic money-wise (as that is the sole consideration of engine tuning, as money > infinity so does skill, tuning, etc as you can hire other people to do it) to add octane / fuel vs fix whatever tuning or problem there is.

sometimes its not something easy to fix (for example the way the combustion chambers are designed on a motor might give realistic limits to what can be done with 'normal' octane as far as how much boost etc can be handled) ...

Sehn, I couldn't have said it better myself....

It just comes down to wording - I see it as an alternative, not a bandaid. The points him and many others present are valid, but injection can produce results (or mask flaws, whichever way you look at it). In some instances I find it to be a perfectly viable option
