Hi I have a hi compression gsr 12.3:1 so I need to run 100oct or better. So has any one every ran race gas concentrate. Does it cause any detonation or anything and I was wounder if the racegas concentrate can be poured directly in the tank after filling up or do you need to mix it in a gas can first then pore it in

 

Good stuff, actually. you mix out with your fuel based upon a ratio (pre- calculated on a chart given). best to use 6 gallon cans to mix in as opposed ti pouring directly into the fuel tank

 

Oh cool thanks alot. I saw it on jegs.com but it says it only raises 4oct points is that true or can it make 100oct

 

4 points from the highest pump fuel you're using. if you want higher, you might need to contact VP fuels

 

Can't run E85 intstead??

 

Bah. inconsistent unless using a flex fuel sensor. I never use the stuff.

 

Not really a big deal since 50% ethanol gives 90% of the air-charge cooling that 98% ethanol does. It also enriches with a lower % mixture, so a lower ethanol mix somewhat fixes itself.

If you look at the tests Evo guys have posted, they get zero knock on their high-boost E85 tunes when they switch to E70.

 

Did that years ago (Former Evolution Owner). Still glad I don't use it. BTUs are too low.
