I am in the process of getting my Aquamist up and running and I want to know what road racers are using. A 50/50 mix would give me some added cooling, but what is the norm for road racing?

 

I use 100% meth at NASA and SCCA

 

Depends on what kind of power you need. If you're ok on power, 50/50 will give you better cooling throughout the system and more reliable knock protection.

 

Aqmist will tell you water is best but in the USA the general opinion is 100% methanol is best.

 

I've tried 50/50, 60/40 80/20 (meth/water) and 100% meth. So far 100% meth and 80/20 seem about equal, but I think I can get more power out of 100% with a bit more time tuning. 100% is alot easier to mix.... I'm on 90 octane fuel up here in alaska. I'm sure on race fuel running more water would be best but I'd rather not spend the extra cash on race fuel.

My opinion and experience is that the lower octane your fuel, the more you will benefit from a higher methanol %
