Forced Induction, 87 Octane, and Octane Booster

For some stupid reason, the one track that is open in Korea track does not sell fuel and there is has no premium fuel within 1 hour.

I already carry 2 5 gal cans to the track and start with a full tank. The drive there is very hilly so I use 1/2 tank to get there and then a little more to get back (traffic).

Is using octane booster a viable option to get home? My car is already fully packed with gear, not sure that I can fit another 5 gallon gas can in my car.

The real problem is the mountains. I try to stay out of boost but it is almost impossible on the hills and all of the d1ckhead drivers here...me being one of them

Octane booster is a product i wont trust.

You'd be better of mixing 50/50 gas/ethanol to get a higher octane(though you should keep an eye on exaust temps as ethanol can lean out the engine abit if not monitored)

Thanks. What ratio of gas to toluene should I use?

Although the real answer should be the TRACK gets some FOCKING FUEL! Makes too much sense I guess.

I'd do about 1.5 to 2 gallons for every 8 gallons of 87

The octane can be closely approximated by: %Toulene * 114 + %Gas * 87 = % Octane

so a 30% toulene, 70% 87 octane mix would look like:

.3 * 114 + .7 * 87 = 95.1 octane

and for 30% xylene:

.3 * 117 + .7 * 87 = 96 octane

30% is the max you want to mix for toulene/xylene

Actually, I just need to get the octane up to 93. So I guess I can use a 1:4 mix of toulene to 87 octane.

With all this mixing, I guess it would be easier and cheaper to just suck it up and bring 3 5g cans of 93 with me. Dang, my car is turning into the first BMW fueler.

In my area outside of Montreal we have very limited access to premium fuel. In the remote areas drug racing is very popular but there is no good fuel. VP racing fuel is very popular.

What I used to do when I needed premium fuel was using MS109 VP racing fuel instead of the octan booster. I mixed it with 87 oct (70% 87oct and 30% 109 oct) and the result was always perfect. I had really good experience with fuel mixing. However it is very expensive but worth when you really race and need good times.

This is just an HPDE for fun. No access to racing fuel here...are at least none that I know of.

I really wanted to avoid bringing a 3rd fuel jug but I would end up needing another jug of toulene...I'll just bring another 5 gal jug.

This why I'm a fan of water/meth injection , in the off chance premium isn't available you have some extra protection

But here in Korea, I think Meth might be hard to find.

This or Torco Accelorator, are the only real octane boosters that actually raise gasoline octane.
