Running Straight Meth
My question goes out the those that have been running meth straight for 6k or more miles in there setups. Visited with one of my Viper buddies who is putting down a mere 960 rwhp and at 6k the rings were showing some wear. He was running good and had an oil leak so during the fix he decided to pull the pistons and that is when the builder found the issue and he was running straight meth like I have for 4k now. What do we see in the LSX setup? Will we see the same thing as my buddy in his viper does? He does rund a blower on his car like lots of us who are running the Meth?

flashpoint at 140 degree
Snow performance recommend at least 20% H2O mix from a safety standpoint.
I've been running 100% meth in my evo and ATI C5, no issue so far. I will go to the 80/20 mix as soon as the tuner can take me in for safety reason.

What safety reasons? I have seen people doing 80/20 or some derivative mixture and I see that as a bigger risk. Unless you tune the car on the fat side, you risk going lean if your mixture is off. Btw, I was probably the 2nd C5 on this board running meth. Been doing it for a good 18 or so months...and I have had no problems at all.

Bob, thanks for your response on this as I have my car running fat and bet there must have been an issue with the Viper's motor, looks like I will continue the straight running of the meth

This has nothing to do with AFR which I believe even if you're a bit off with your mix should not be affected by it. The % variance will be so small.

But if you are using alky/water to reduce IAT and add some safety, then a normal tune is going to be required. Water in this case has more latent heat do to phase change, so it cools better then meth alone, although without safety of additional octane. A mix in this case would have advantages and any hick-up with system will hopefully not grenade motor.
Just some thoughts,
Mike

I'm not a big fan of spraying alky on top of an already rich tune. I think that will eventually cause problems and is the reason that I tune for the spray and keep my fingers crossed that the pump never fails….

This is incorrect.... The flash point of methanol is 725 degrees F TLV/TWA (Threshold Limit Value/Time Weighted Average) 200 ppm .

I've been running Julios kit well before ECS started to carry it. I run straight meth!
I run the **** out of my car, and don't burn a drop of oil after almost a year and a half of drinking a sh!tload of Meth...

According to MSDS sheets, flashpoint is 52*F (11*C)
Boiling point is 148*F (65*C)
Auto-ignition temperature is 464* C

Why are we discussing flashpoint anyway... Flashpoint is a scientific term for the temperature at which a substance will ignite when exposed to an open flame... If you have a fire under your hood there is more to worry about than meth.

Disclaimer: I am not a chemist... But FWIW the flash point is the lowest temperature at which it could burn, not the temperature it will ignite when exposed to open flame. According to MSDS the flash point of methanol is 50 degrees F...
To that end, I think the autoignition temperature is more interesting than the flash point. The autoignition temperature of methanol is around 850 degrees F. A hot turbo or other really hot exhaust components could reach that temperature...

Also check out Wikipedia. I know, not the most perfect scientific sources but generally accurate.

IMHO the only physical danger of methanol in the engine bay is if the tank dislodges and somehow works its way down to the exhaust where a lot of it is ignited at once. Lots of guys have been running 100% methanol for a long time and I would bet you'd be hard pressed to find a catastrophic event tied to even just a moderate leak.
Now again, if the tank dislodged, or you had some other catastrophic event (rollover) then yes, the methanol could easily pose a danger.. but so would the gasoline in your tanks.

We seem to be getting off track for what I wanted to know and that is how are our engines holding up for those using straight meth, not the flash point, and I still would like to hear from more of the meth users that have lots of miles on there setup and how they are still performing

9,000 miles on my 2004 Vortech SC Z06 running straight meth during boost. Stock bottom end, 532 rwhp. 15,000 total miles on the vehicle. Installed the meth injection at 6,000 miles for added safety and peace of mind. No oil burning or any other issues.
