Yup! Lower intake air temps mean more timing and more dense intake charge. For example, on an 80 degree day, no matter how efficient your IC is, even if it was a magical 100% efficient core, it would only lower the charge temp to 80 degrees. With meth, I can be on a boosting on a 95 degree day, and have 60 degree intake temps. Its wonderful.

As for the other benefits, you have more octane, cooler temps, and other properties of the meth injection that all help prevent knock. This saves your motor and again, allows you to run more timing.

Finally, the meth injection acts like a steam cleaner, keeping your motor clean. Its awesome

 

you saw 100hp/80tq gain?

 

thats nothing surprising....

it depends how aggressive the tune is and how much is being injected

 

What's the exact octane rating on Meth? Trying to decide E85 or 50/50 Meth/water.

 

i state this every time i see a post like this. if you dont have the cash on the side to rebuild your motor, dont do it....friend blew two evo motors, go 2 tunes race gas/pump.

 

There are many types of alcohols. Methanol is one of those types...

This may be controversial, but I'll throw it out there. 93oct. with 50/50 mix ~ 105oct.
This is a figure that I've heard of... I can't prove it.

 

meth is like 123 RON

but thats 100%, no mixture

 

if the evo is your daily drive, you gotta be crazy to even think about running meth on your car. It takes the Enjoyment out of it. I ran it for a month and it was the worse experience i had ever done to my evo.


Good luck

 

Yeah, I ran 100% methanol and got approximately 100hp/80tq. Thing is I use a *LOT* of meth. Granted I just have you bolt-ons and making this much HP...... its scary to thing what I can do with a bigger turbo.

Injen Intake System, Greddy TI-C Exhaust, Hallman MBC and a Buschur IC.

Those are really the only things I have besides the meth kit.

Aquamist is damn good. They don't play games. With just basic bolt-ons!

Now, imagine if you had a fully built engine with a HTA35R...... WITH METH! BWAHAHAHAHAHAHAHAHAA!!!!!!!

*cough cough* Sorry, got carried away there...... But make sure you got it tuned and installed right. And once you start using it, be prepared to maintain the upkeep and maintenence.

You take care of the car, the car with take care of you. I've had no problems at all.

Meth is only as good as the quality of the kit that you get. That Snow Performance stuff.... no sir.... Meth is a drug, would you get the real Viagra, or would you get the Viagra knock off made in some hoopte unknown location? I would think that something as important as Viagra...... I would get the real thing!

 

Which kit were you using? Care to explain why you hated it so much?

 

If you have it nearby, I suggest E85 is much safer than a meth. I gained 76whp and 132 trq when I went to E85. No need for any fail-safes or any additional non-OEM equipment.

 

failsafes are great but not even close to protecting your motor. failsafes will protect you if your meth runs out before you hit high boost. But if your already in high boost and your meth runs out. Right AT THAT INSTANT your in high load/high rpm and your a/f ratios will be lean because of no meth. its impossible to instantly drop boost from 30psi to wastegate. Sure it drops fast, say like 0.25 seconds. But that is enough time to blew your motor easily!!!!!!!!!
same thing with map changing ROM mods. It dont magically instantly change maps. it does take tenths of a second for this to happen, more than anough time for engine damage to occure.
another thing as already mentioned. Cylinder wash, i totally agree with this and makes perfect sense to me I dont care how many people have used meth for years. Just because their motor is still working dont mean they are not decreasing the life of it. Kinda same thing for guys who only change their oil every 10,000 miles. Sure your motor is still running, but i bet your decreasing the life of it by not changing it every 3,000.
Meth injection was used way back in World War 2 during emergency take offs and evasive action. ask yourself this question, why didn't the us government use it 100% of the time insteasd of just during emergencies?
ANSWER im sure is because it would decrease the life of the plane and make it not dependable during combate.

 

wow alot of good reading in here.... personally don't run it....know a few people on stock blocks seems to be safe...

 

Why? I assume you messed up, and then blamed the kit you got or something?

 

wow, i guess i'm really the epidome of your post then. last time i changed my oil was 10k miles ago. i run 30psi daily driving my evo with meth and a 35r turbo. stock motor, stock head gasket, stock studs. i had to add a half quart of oil 1000 miles ago, and will be doing new oil/filter when i get my car back from paint. oh, and i have 70,000 miles on my car, 10-12k with 500whp, and 60,000 miles with 320+whp.


as for your WW2 reference, thats silly. why would ANYONE run meth injection all the time? when you are just cruising around you don't need meth. thats why the systems triggers at a certain boost level. same thing for the fighter planes, they only triggered their water injection systems when they needed the power boost. otherwise they would have to carry around a giant tank full of water in addition to the gas.
