Ok.....I mixed my own W/M at 50 /50 and the Meth I got at the race shop [ I was told ] might damage the paint . Maybe I took him wrong and it was the 100% meth that might hurt the paint .

My tank leaked off and one the whole time I had it . It was installed correctly too .

 

I have a friend that is using the OEM windshield washer tank for over 2 years without a problem. I've had mine for 1 1/2 year and no leak what so ever. I like using the windshield washer tank coz it has its own fluid level sensor that light up on the dashboard and I dont need another tank that will take up space.

 

I use the alcohol injection systems trunk mount stage 1. It has a boost trigger, works really nicely, and comes plug and play out of the box. (just have to hook up power,ground,vaccum line, water line)

 

I am planning to install HFS-6 in next week. What size injector do you guys use and where did you guys put it? I have seem injector size calculator from evolutionm.net, but just wanna know what you guys are using. I am planning using 50/50


APS TT with DW 600cc (14psi)

 

I just kept increasing my nozzle size til I saw a 1 point drop in AFR between my meth and not meth maps. So use the calc, start there and go bigger until you see at least a 1 point drop with 50/50

 

str8dum1 thank you I now know where to start. Where did you put your injetors?
Some say rigth after intercooler and others say right before TB.

 

Put the nozzle right before the throttle body.

 

well more specifically you want it as far away from the TB but behind the MAF. give more time for atomization and dispersement of the spray.

 

I have always put meth nozzles close to the TB. It's not nitrous. I position meth nozzles about 3 inches from the TB. Nitrous nozzles on the other hand should be around 6 inches from TB. Water/Meth will evaporate before your TB if u position it to far. And you will not get results you are looking for.

 

So say I'm running 11.1-11.4 AFR on pump gas right now. I add the meth and when I see 10.1-10.4 I stop adding meth. Do I now pull fuel until it gets back to 11.1-11.4?

 

Well technically, your detonation threshold is higher so you could run even leaner. I would only do this if you have great faith in your fail safe. You may want to test that out fully before leaning out AFR or advancing timing too far.

 

You mean after the MAF, so the MAF doesn't get sprayed I presume. If you have a recirc BOV (JWT kits), keep in mind that you'd likely want to spray after that as well (or you'd dump W/M into the compressor intake between shifts).

 

Correct you will need to take away fuel. I always just ran a meth map. No big deal just make sure your tank is allways full. If not you will get some serious knock counts. And that depends on how aggressive your timing is. I can't wait till I get another meth setup. But will be running straight meth on two maps this go around.

 

I know this is off topic. But how do you guys think meth would act on a E85 fuel system setup. They say E85 burns cooler so you can add more timing. But I wonder what the combination of both would do. Any ideas.

 

yup, thats how you do it.

YOu can pull it back to around 12's and advance the timing 3-6*. You'd need a dyno to really help you there though.


so where does this evaporated meth/water go? Oh right, straight into the plenum. Its not an open system. YOu want it to evaporate. That what takes the heat away. Google enthalpy of vaporization if you want to learn more.

They are both alcohol fuels. It would be redundant.

 

This is a quote from a Snow Tech:

"The longer the fluid is present in the air intake tract the longer it has to pull heat from the air charge. This is great for reducing IATs but this limits how much fluid gets into the combustion chamber where it acts as a fuel and detonation suppresant. We generically recommend that the nozzle be placed before the throttle body or throttle plate that way it has some time to reduce IATs and still act as a fuel."

 

"In regards to the nozzle placement for cooling versus consumption as a fuel: We have a generic recommendation that the nozzle be placed before the throttle body. This usually provides a "happy medium" that allows for IAT reductions and increased detonation control. The closer you are to the combustion chamber the more the fluid acts as a fuel and the farther away from the combustion chamber the more the fluid acts as an intercooler. Data logging and tuning are normally the best way to determine optimal nozzle placement for your specific application.

In regards to nozzle selection: it is correct in that we base the injection quantity off of a percentage of primary fuel flow. Our nozzle selection guide (and any other guide) is exactly that: a guide. There is nothing absolute in the information we provide regarding nozzle selection because there are so many variable at play on different applications. We can get you close but final tuning is up to the end user."

 

anyone use the AEM kit? or comments on it? I have one sitting in my closet I have been meaning to install

 

frankie945, I don't know why SNOW would say that methanol gas won't act as a fuel. As far as I know either as a liquid or a gas, it will burn.

 

That was just a Quote for one of the snow tech's off the snow performance forums.

I would say just because the closer you put it into the combustion chamber the more it is going to act like a fuel. Because it is still in more of a liquid form. And of course would lead to pulling tons of fuel out of your cells, ems, whatever you have to make up the difference in AFR's.

The further away meaning way down the intake pipe or in the intercooler the spray, when under boost it is being sprayed faster and just misting through the intake pipe or pipes giving more of a cooling effect.
