Methanol injection

[Chris58]

While Ive been waiting on new pistons I've been working on installing methanol/water injection on the vtr.
Y'all will call me crazy for putting ot on a naturally aspirated engine.. but there seems to be alot of pros, even on a n/a engine

It will run cooler
Adds a couple hp and a little torque
Ability to run slightly more spark advance
Shiny insides
87 octane fuel with high compression

I figure it will pay for itself ($300). Premium gas in my neck of the woods is $1.30 - $1.40/litre while regular is $1.10. My calculations say around 80 fill ups should pay for it.

Ill post a few pics of what I have done so far tomorrow.

Anyone else do anything like this? What do you guys think?

Interesting project. Not sure how you plan to inject it but the stuff is highly corrosive to the fuel system...

[Chris58]

I put the air filter in the lid of my airbox to make room.. pretty sure i saw you did the same thing somewhere on here?? Then installed a injector over each velocity stack.
I will probably just inject water, and use washer fluid when it gets colder outside.
I was worried about the corrosion as well, so I googled it. Ive read it doesn't seem to cause problems going through carbs

you saw correctly, am on my 3rd edition of the filter-in-lid (actually, 3.2 as I just did another revision over the winter). works very well once you get it jetted...

[Chris58]

Nice! I just covered over the snorkel and cut a square in the lid that the filter fits in.. I can't understand what they were thinking with the oem design...seems the filter was awfully close the the stacks, but maybe its a bit quieter..

An interesting topic

I'd look forward to hearing how it all goes

Heres what I have so far. Thats a 1 gallon tank fit into the tail, I had to put the pump in the battery box, and a lithium battery fits under it. The injection pump is controlled by a adjustable vaccum switch and relay.

Interesting plumbing (cue Jamie) - can't wait to see dyno chart on what it churns out.
