In-tank Methanol Tuning

[JgamB]

I spoke briefly with @Justin@Freektune; about in-tank methanol, and it appears it's an overlooked means of getting E85 performance by visiting Home Depot instead of trying to find a station with Corn.

There are some upsides to it:

No meth kit needed, so no plumbing, wiring, failsafes, nozzles, etc. to worry about. No additional tank to keep full or mount somewhere you might be uncomfortable with for safety.

2 Gallons of Meth will give you the knock protection of ~3 gallons of E85, so you can get that sweet spark advance and give up just a little bit less specific gravity (fuel overhead) with a higher gasoline concentration.

And of course the downsides:

It's being consumed all of the time, unlike a MAF/MAP based controller that is only using methanol when you demand it with your right foot.

It's comparatively expensive.

You aren't getting *extra* fueling like a meth kit can provide, but if you're not looking for 400hp or more it isn't going to matter.


Justin stated he's got a couple/few cars that have been running like this for quite some time, and used to do it himself for a couple of years. If you don't want to install a meth kit, and you can't get E85 readily but want more power, this could be a viable alternative. I'm just tossing it out there because it looks like a solid alternative to get some alcohol in your combustion chamber with minimal fuss and great results.
