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).

In for longer, easier to see vids.

First of all id like to thank the moderators for reopening the thread and i want to clear out all these roll races take place in a closed highway.

Anyway Here we go again sorry for the short vids but some ppl hate losing and decide to let go, Not my fault :shakes head:

The same nismo on race fuel and high boost vs 2010 camaro with bolts,cam upgrade and 75 shot of juice, The race ended because the camaro mishifted and didn't want to try again sadly because he was filmed.

and vs gallardo superlagera, Deal was gallardo takes the jump by a car length and decided suddenly to stop i guess because he was shocked:ughdance: and didn't want to try again as well:eekdance:

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?

damn thats a sick Nismo and set up... i feel like there arent many people running the greddy kits here, or atleast dont have the build threads like the other brands do.

Greddy kits r very expensive compared to others.

I have the tank in the trunk, 50% meth is for sure safer but on a stock block running sometimes high boost you cant risk a small missfire or knock so you have to accept the danger of pure meth, So i run 100% and its doing fine till now of course i dont run high boost all the time because its tuned on 100% meth and ms109 fuel, its usually on 11 to 12psi on 93 pump and 100%meth, I am sure its not going to last but so far the stock block is strong as hell .

The last vid is a 40th anniv 370z not the nismo in the first couple of vids i posted, The 40th anniv 370z is equipped with gtm stage 1 on 10psi no meth or anything pushing 480whp on a mustang dyno which is 500+on a dyno jet, a c6 is easy to kill with this set up no need for the white nismo which pushes approx 550 to 600whp :tiphat:

This is the Go pro angle from the vette (pushing approx 430whp on a mustang dyno) against the 40th anniv 370z with a gtm stage 1 kit (470whp to 480whp on a mustang dyno), Runs are from 100km and 70km, The cars in the middle are cars with professional drivers and video shooters who are recording the race in the mid section and the end.

Noted, 470hp is a lot on a Z:happydance:

makes me proud to have a 370...... even if its not boosted. :P

dodging a few cars in that last vid, eh?

470 whp to 600whp will make any Z owner more proud even is more than enough on the streets , I am sure i am not the strongest but it does the job just fine for a daily driver :tiphat:

Those videos really put it into perspective what 450 - 600hp will do for the Z.
