what a safe mix of 93oct and 104 oct?
plan on going to the track (1/4)

 

You can add as much 104 to your car as you want. Its unleaded, it wont hurt your car.

 

Anything you want to do really...even strait 104. just so you know its not really going to help unless its tuned for it. I put race gas in and turned the boost to 25psi and went more than a 1/2 second slower and lost almost 5 mph. Basically dont waste your $ or only put in a gallon if you have a 1/4 tank.

This is for 91 + 100 oct but you get the picture.

 

^^^thanks, but is it worth it because im not going to turn my boost any

 

Thats weird you went slower on race fuel, I ran 12.3-12.4 on pump at 21psi, 3600 ft trapping 113.09, i bumped boost to 25.5, then ran 12.08 at 115.7-116.25 on race fuel with no tune, maybe you did not get true 100 octane which has happened to some members when they got it out of a pump and your car pulled a ton of timing or something?

 

Just adding race gas won't do anything, unless your tune is off, i.e. knocking. So no, its not worth it if your not turning up the boost. The point of adding race gas would be to turn your boost up.
