Methanol kit

[Dogo]

?. I ran an alcohol kit years ago. Found it to be corrosive. Alky tank in trunk is a good idea. Also Alky does wash down cylinders making oil to break down. This is what I found. Am I right or wrong? Don't beat me up on this . I'm a old timer.

I can't imagine it any more corrosive than the alcohol in E85; which supposedly is not. Both remove oil better than gas does. I am using 2500 mile intervals, not sure if that helps or is even necessary but oil is so cheap.

You'll only have 1 reading, its broken out of the maf harness to then be read by the new sensor in the manifold. Higher temp comes from being in the manifold, closer to the engine with lack of air flow when TB is mostly closed.

Thanks for the info. Will let Rob at PBD know and get an updated tune

Methanol is MORE corrosive than Ethanol (can google this), however that is only if you are using the methanol against metals in liquid form, but it is being evaporated much more quicker than the water would be. In this case it would only provide cooling and a modest octane boost. There are studies that show pure water can have the same effect if you are worried about the methanol. Cylinder washdown would only occur if there is a lot of unburnt methanol pooled in the Cylinder.

Another dumb question

Why wouldn't a tune be required to run meth? I too have been researching adding it to my car but assumed I needed a revised tune. Thanks for all the info guys! Good thread

I am running mine only for cooling, on E85. My IATs were resulting in timing being pulled on the back half. No need to adjust tune for that, comes on at 8psi. Also getting ready for a bigger blower, which will make even more heat.

So the meth just cools the charge then? I need it for the cooling, my cars a track only car and my temps are high here in FL. I was thinking of adding an on off switch when I hit 2nd gear, nothing fancy.

you’re not adding a whole lot, mostly vaporizes and causes a temp drop. If the O2s catch a slightly richer mix than targeted it pulls back a little e85.

Ya. I just read about it. Seems like a no brainer.

Yep and don't need anything fancy, just use the progressive controller and have it come on at about 2/3 max boost and ramp to full boost. Very easy solution for an undersized IC for a few hot months out of the year.

I mounted everything in the trunk on Plexi glass and can remove it all with a couple nuts and disconnecting the lines when it is cool enough to not require it.

Thanks.
Pardon my ignorance but does this "transfer" the IAT sensor in the MAF to wherever I install it or is it a new IAT sensor completely meaning I'll have two IAT readings (IAT1 and IAT2)?
Right now on my Ngauge my IAT shows the expected value (5 above ambient or so) while my IAT2 shows as -40 which I assume means it's not functional/no IAT2 sensor

Also am I correct in assuming the elevated temp readings are from taking the readings closer to the engine block?


Do you know where I can find instructions for that?
I haven't got the faintest idea where to begin except I'll need a temperature sensor, some MAF connectors, and some wires

You can get a maf extension harness on Amazon or eBay for $10-$15 and follow this.

You don’t really need a tune. If you are using it for cooling then you definitely don’t need a tune. If you are using it for octane boost then you want a tune to take advantage of the extra octane otherwise you are just wasting your money. If you want cooling andoctane boost you can run a big nozzle far away from the throttle body or run two nozzles. One as far away from the throttle body and another closer. For octane you need to be sure that the w/m has not completely evaporated by the time it reaches the cylinders. For cooling you want it to completely evaporate before reaching the cylinders. You can increase 91 octane to 110 octane with the right nozzle/nozzles

The short term fuel trims will take care of the minimal increase in fueling. As long as you don't get too carried away and have to start removing fuel from the tune. I use my methanol system for octane enhancement, but don't go so far that fuel is removed from the tune. I just let my STFT's take care of the AFR. Probably over simplifying it, but it just works.

I would suggest devils own...

Are you PD supercharged? If so I would look into some spacers as well. so that the heat transfer to from the head is buffered.

A cooler intake charge is like having more octane (also can google this, tons of scholarly articles on intake temps and detonation suppression). If you're worried about fueling and having the O2 seeing that, as @Jackson1320 has stated just make sure it gets evaporated before it reaches the Cylinders: use less spray.
