Thanks for the replys.

I def. want to retune for the meth, but would like to be able to add the kit and use it slightly without needing a retune till i can get it up to TJ.

Like i said i just dont want to ever have to worry about a malfunction having an adverse affect on my engine if a problem would ever arise.

Basically i want max effort tune with blower only but thought the meth would help the IAT's to keep me from suffering from pulled timing due to heat soak or high ambient temps.




Does any one have any data on how much ET drop meth adds??

 

Running 100% meth, I typically see no less than a 30° drop, given enough time in boost. Have seen 45° drops though.

 

since where on the subject how long does meth last, lets say if i use the windshield washer tank, on average?

 

Depends on your driving style. I probably drive a bit more aggressive than most and go through a tank every 3-4 weeks or so. This last weekend between driving the **** out of it for 2 nights in a row and several looong dyno pulls, it went through about a gallon.

Interested for exactly the same reasons as TimZ. Right now we have 95° temps with humidity of 80% where I live, and it actually feels like 112° says the weather channel. 100°-110° temps are not unusual either.

 

Great info , Thanks bro, 30* definitleyw arrants getting meth IMO !

Didnt know it lasted that long either LOL.

Cool deal bud, sounds like you need meth too.

 

you can't run meth and not tune...think of Meth as GAS. It's a fuel supplement ok? Your adding fuel you need to add air. Since you can't add air you need to decrease the amount of fuel given by the injectors.

Even turned down low you are still adding fuel.
Meth does not really lower IAT's as much as allow increased timing by way of raising the average octane of burned combined fuels (gasoline and meth).

I can make 5 gallons last 3 years...I have actually only burned about 3 gallons in the last 2 years by the way my controller is setup to not come on until 5psi.

Believe me, I was concerned by the added complexity of a meth system and consequences of a failure but it's a risk you take when you want the most from your systems, ehh? It's a risk just putting a blower on an otherwise good engine

 

I have heard good things about alky control kits. I am leaning that way at some point. I figure ill have it start at 3-4 psi and come on full at like 7-8. For the amount i drive it the meth should last forever.

 

Do most run 100% methanol in there alky control kits?

 

Also what afr are you meth guys shooting for? Meth has a lower stoich so i would guess high 10's to 11 if only spraying one 15 nozzle
