will adding water/meth to a untuned mini help?

 

IMHO, yes. Anything that reduces charge temps is a good thing... and water/meth does that. Water/meth can also prevent detonation, allowing the ECU to advance timing, making more power.

The only real benefit of tuning for water/meth is to account for the combustible fuel addition of the methanol - but really only an issue if you're spraying a high meth concentration and a lot of it... I spray only a little bit of low concentration, for cooling only.

Downside of tuning for meth is that then you're hooked - not safe to drive without meth if the car is tuned to expect it... you'd be running lean...

 

i don't knoe what IMHo means, but ok i think im going to get it what kit do you have.

 

IMHO = In My Humble Opinion

I have the Devil's Own kit.

Lot's of good reading in this tread, if you can make it through it - it goes off on a bunch of tangents, but has a lot of good info:

Here's my install:

While this is for a first-gen MINI, most of the concepts apply regardless. For a 2nd gen MCS, you may get best results spraying with a 1gph nozzle pre-turbo and with a 1gph or 2gph nozzle post-IC.

The kits are available through AutoXcooper.com

 

heres ones from atla, seems prity good for teh price

You realize thats for the nozzle only?

 

i think he does

 

To answer your question- I can think of a way to test it.
Go fill up with some nice unleaded race gas, like 100-105 octane, disconnect the battery and leave it for a while, hook it back up and drive the car. If it feels much faster than before, the ecu adapted to it and water meth will work great. Best way to test!

 

Is the addition of water/methanol to pump premium equivalent to running 100-105 octane gasoline as far as its anti-detonation properties go? Or did you just pick 100-105 in order to completely eliminate the possibility of the knock sensor activating during the test?

 

I've heard lots of folks say "it's like running race gas all the time" but I haven't seen the data to back that up... I suspect it also has a lot to do with the system you're running, how much you're spraying, methanol concentration, how the car's tuned, etc..

 

Yeah it effectively raises the octane of the fuel and cools IATs as a side effect. What I'm trying to figure out is if the ecu will compensate UP by adding timing, or just by taking it away when you hit the knock sensors. If it runs a decent amount more timing on race gas, then water meth would be great.

I've heard running 75/25 (water/meth) works great.

 

You don't need to disconnect the battery to test this. If you increase the octane of the fuel, or add the anti-knock property of water, the ECU will adapt right away. Just log the timing out of the OBD port running regular pump and whatever upgrade you go with. I haven't logged the GEN2, I hope to next week, but the GEN1 will increase timing all the way to the max programmed into the ECU if you get the injection and mix right no matter how hot outside( I've done it in 110 degree heat in CA). Otherwise, during heatsoak on the GEN1 you could be losing up to 10 degrees of timing, or more.

 

i went 100 percent meth last week and whoa big difference . good to know but expensive lol
.

 

 

you can buy a gallon of alcohol at a hardware store for like 8 bucks

 

You can run the blue windshield water fluid too.

Water injection came from what is known as ADI in the aircraft industry. It was used on wwII error aircrafts that had radial engines. They would use it on take off when they went to full take off power.

ADI stands for Anti-Detonation Injection and now over the pass few years it has become popular for boosted cars. YOu can run straight water if you want, that will still cool off the charge air and reduce the chance of you detonating. The meth setup is fuel so you get a cooling plus an added fuel to raise your anti-knock value.

Remember, water will cool down cylinder heat temps and prevent detonation but it does not raise the anti knock value (octane) of your fuel.

Some 101 info for you guys. I miss them airplanes.....

 

i ran the ww fluid but the pure meth is better.

 

That ww fluid is usually 30%. There's been a lot of resaerch and technology development since the WWII days.

 

I was not telling you which was best, i was saying use WW fluid if $ is an issue with meth. Also i was giving you info on how WI came about.

 

i know... not trying to be obnoxious just comes naturally
sry.

 

I run the 30-35% washer fluid and am happy with the results... and it's $1.70 per gallon pre-mixed at the Advance Auto at the end of my street.
