I started with 50/50, and didn't see much benefit on my Radix. Most kits suggest you run 50/50 so it is not a flammable tank under the hood(from everything I have read). It is suggested that you mix it 50/50, and tune your vehicle 1.0 leaner than your desired AFR. Then you adjust nozzle size to bring the AFR back to where you want it. If you were going to run straight meth, I see nothing wrong with it other than the flammable liquid, and the premature seal problems. Don't forget that if you use a large nozzle, it is acting as a fuel, and if you run low, you chance leaning out your engine. I use an overflow tank for a coolant system with the supplied low coolant switch. I intended to run that to my valet mode on my efilive COS. If I run low, it won't rev past a desired RPM.

 

That's a great idea Gadgetized.

 

Another pure meth user here. For all the reasons already posted. I would also add that if you are using meth as part of your fueling, then I would pick a slightly richer target A/F ratio due to the stoich of meth. And good luck getting a nice transition in the tuning. It can be done but it's a pain in the ***, at least for me and my three nozzles....

 

100% meth here

 

Cool info. I used to run 50/50 but lately just run striaght meth...when my meth system works...

 

Alky-control!
Straight up meth
Using one M15 nozzle now and hoping to add the other M15 when I bolton the PT76. IAT's went from 130's to a steady 77 on a south Ga july afternoon. Can't beat that with a stick!

 

ive run -20* WWF (~30% methanol), ran 1 gallon mixed with 1 gallon of -20*WWF, and ran it straight..

Straight is easier to deal with

IATs dont drop as much but your running a higher OCT fuel so you can still play with the timing.
IATs dropped faster and lower with the -20*wwf.

now im running a Devils own 10, 14, and 7 nozzle 31GPH worth.

 

I have a 3qt tank in mine. I add 1 qt of wwf 20-30% meth content and then fill up the rest with 100% meth. It yields me around 75-80% meth and 20-25% H2O. Helps my pump a little and helps me keep an easy eye on the level.

 

yea straight meth is hard to see in the reserviors... gotta get around to putting my low level switch in..

 

Send that piece of **** system back to who-ever you bought it from.
