Isn't meth lower octane than race fuel? I haven't really seen them used together.

I believe it's a tad lower than high octane race fuels, but the benefit of cooling the intake charge so much outweighs the small loss in octane.

Anecdote: My friend has a Mazdaspeed3 with a trunk meth setup, and under full boost and load, his intake temps, measured at the manifold, are around 70-75 degrees F. And this is in South Florida during the past summer.

Hi guys this is the dyno chart i have which was tuned on 100 octane pump gas and meth, both on low and high boost, I dont have the actual dyno chart for the setup as is because When it came here since we don't have 100octane pump gas in the station, We are running MS103 for high boost and meth and 93 and meth for low boost, We only had to do small adjustment to the tune. its making some where in the 500 to 550 on low boost (10-12psi) and 600-650 on high boost ( 13-15psi).

Nice numbers - not sure how long the stock block will handle it as you know.

I used to run big boost on my last car - and ran Methanol on a race tune for a while.

For us - we found that 50/50 water meth actually brought the IATs down better than straight meth and then no fire hazard. Something to think about if you're going to keep pushing the meth.

Had my meth set up in the trunk - where do you have yours rigged?
