Water/Methanol vs. Race Gas...What\'s the Difference?

Guys,

Doing a little research before my ROE S/C install and to run 10PSI, I was told it would be a good idea to add the H20/**** kit. What is the difference between that vs. running race gas? Both allow you to increase boost and advance timing. I can readily get 110 octane here. I was thinking just have a few different cards, one for 93 octance, one for a race gas mix (100 octane), a track card, etc. What are the drawbacks and benefits of H20/**** vs. race gas? TIA.

I personally think that the **** kit is more convinient. My buddy down the street has a 700 hp Supra. He HAS to run race gas all the time to have that power. That gets expensive. The Race gas is consumed when the car runs. My **** is only consumed under boost. I can drive around town for months under vacume on pump gas but when I punch it, the **** comes on.

cost is the big difference.

Good point, thank you!

The other factor, is that initial tuning of the Water/**** is tricky. But once tuned in it is pretty reliable. I had my tuner use the windshield water bottle, and that is pretty convienent, but it empties out pretty quick if you are out driving hard. I'm also not sure of having the Methanol water mix so close to the hot engine compartment, but so far so good. I have not run it in the dead heat of summer yet. I will check to see if it evaporates just from normal driving this summer. It beats taking up trunk space though. I still throw in a gallon of 110 to my tank to make sure the car never detonates. But is costs around $10/gallon at race shops here. So it is definitely better for cost reasons. If you are going to track your car, use the 110 gas and card for that, because you will run out of water/**** while you are on course, and that is not good.

If you use the large W/M tank supplied by Roe, you will not run out of W/M mix before you run out of gas. I'm running through two tanks of gas for every fill of W/M.

A benefit of **** is your off boost throttle response will be much better on normal gas.

A really high octane fuel will make the car feel a little sluggish until things get really boosted, unless you roll a whole bunch of timing back in.
