So I'm currently running 50% methanol and 50% distilled water. I know some have been more successful running a higher percentage of methanol. I recently went from the 80mm on the TVS down to the 75MM pulley. I was running about as much timing as you can on the 80MM. All other things being the same running the same timing with the 75MM I have 1-4 degrees max knock in 2-3 cells above 6800rpm.

I was able to pull some timing and have it run zero knock across the board but I'd really like to be able to run max timing like I was before with the added boost. I'm moving to a 67% methanol 33% water solution. I'm hoping this change will allow for the added timing.

 

What size nozzle are you using?

 

75/25 and above is what you will need.

 

I'm doing 2 parts pure meth to one part washer fluid. That puts me around 75%. But, I think I might go to 4 to 1 to bump it up more to like 90%. Is there a problem with running 100%??? IDK why I just don't do that.

 

good to know at least if anything im not using enough methanol then

 

100% may cause the alcohol to evap before it reaches the cyl.

90/10 is the best setup. If your worrying about your IATs, 75/25 is the lowest i would go.

 

im running 70/30 meth with 5gph nozzle... running a fair a mount of timing with it... dont know if going to a 7gph nozzle will allow more timing... idk how high people are putting their timing too tho...

 

Gotta admit, when i opened this thread, i was expecting a discussion about beer to occur....i've been sadly mislead.......

 

haha me too^^^^^

 

yep i was hoping for shiner

 

oh well, if we're talking about meth, I WAS gonna try to run a 50/50 of heet yellow and distilled water. but i could never get my damn kit wired up correctly.
