Using turbo pressure to inject methanol

[Charlie Daubitz]

I was watching Jay Leno and he was showing a 62 or so Olds that had a turbo stock. The factory tapped off the turbo boost to a container with what could be methanol to use the turbo pressure to inject fluid into the inlet through a fixed jet. It made me wonder if it could be used on the Maverick. It just injected when under boost, no pump. Looked super simple and fool proof.

Nothing is foolproof to a sufficiently talented fool.

I am not a turbo expert, yet. But my guess is that it would confuse the computer and you would need a specially tweaked tune for it to behave well, if it worked.

Plenty of kits on the market it's nothing new. https://prometh.com/collections/forced-induction-water-methanol-injection-kits

They ALL use a pump, this one didn't.

Sure it's possible. You would have to play around a lot with nozzle sizes for injector and pill sizes for restrictors. You might still draw fluid under vaccum. Which could be an issue. Get it wrong and you could be looking at hydrolock.

You would also have to inject pre-turbo. There is no ability to do it post turbo really since there would be little to no pressure differential. This is why pumps are used. Pre-turbo injection will increase wear on the compressor wheel, although it will be slow.

IMO there's too much work with a secondary fueling system, which is what methanol will provide more fuel.

Hence when I was into making power, I relied on primary fueling and ethanol. Easy peazy, and with direct injection, it's super hard to knock on even low concentrations of ethanol ~30% +

Works very well when I've used it with my Foxbody Mustang wouldn't see why wouldn't work with the Maverick possibly would definitely need a tune

No pump simple install an inexpensive

I’ve run a water/injection in turbocharged vehicles before. If you use a solenoid instead of a check valve you won’t draw fluid under vacuum like you would with a check valve failure as the solenoid fails closed.

Also if you run a 80/20 or 70/30 water/meth mix (distilled water/methanol with no additives like glycol or detergents) windshield washer fluid with a proper sized nozzle you won’t need a tune.

You would gain cylinder cooling and valve cleaning.

Now if you start run to big of a nozzle or higher methanol content you could effect you air fuel ratio and would definitely need a tune.

I'm ordering as soon as the ordering is open and as soon as I get mine if I get a EcoBoost I'll be definitely looking into running meth injection I just can't decide on hybrid or EcoBoost especially now with the price of gas

Theres a guy on the net who ordered the Ecoboost AWD 4K tow pack, and opened up the intake, and exhaust, then put a tune on it, and it runs I think I remember 13.8 in the quarter and will blow the doors off a stock Subaru WRX. Also he states if he is light on the pedal just driving it, it returns between 39-41 mpg highway.

I wonder how the water injection will help with efficiency and MPG. I mean if you can modify it to get better mileage than a hybrid on the highway, and great performance when you need it, then it's a no brainer. I am planning on doing just that. If the injection setup can bump my mileage another 1 to 2 mpg then why not.

I'm wondering what it would do with a manual throttle body and a cable pedal.

Require extensive programming to get there without throwing itself into limp mode or shutting down. The PCM self-tests the electronic throttle actuation for responsiveness to commanded movements.
