MONTE CARLO "COPO" Monte Carlo SS - Turbosaurus Build (Swinging Dick Racing's c*ck got bent... she bounced a little too high & hard, & came down awkwardly)

[motorheadmike]

One of the side bar projects I have toying with is a low-buck methanol injection system. The $500+ systema are nice - but they are engineered to make somebody else money... and that goes against the general nature of this build.

So I've tossed around a few known options: pre-turbo with a washer pump(s), or a supplemental fuel system using a dedicated alcohol-safe pump that injects post-turbo. I have both of these on hand.

In my intrawebz travels today I learned about waste oil nozzles (which are about $20 on Amazon or ebay) - the problem is they are not tunable. Then I found this video:

Seems easy enough, right? However, it would be a self-tuning system that would adjust its flow rate as the pressure rises. Except one problem - she ain't no diesel running 100psi of boost - and therefore the atomization would suffer at 14.7psi/2 bar. So how could I compensate? Pressurize the fuel source (fuel pump on a Hobbs switch) and apply boost pressure to the air side to compensate for pressure at the nozzle tip (same as a rising rate fuel pressure regulator)?

Not sure yet - it just seems like a fun concept to fart around with.

Color me impressed, you crafty mfer!

Actually used something very similar on some large diesel burners. It's easy to tune with a needle valve before the nozzle on the atomizer. We needed 80 or so psi of air to atomize diesel at around 50gph, you might not need that for something light like meth. I know where to get very effective nozzles but they aren't cheap.

Here's what I have found that works for HVLP: http://www.delavaninc.com/siphon.htm

Pretty sure I could map this out to go from 5 to 20psi and estimate the flow rate - and a 7" lift height is well within reason in an underhood application.

Essentially, this could be designed around a closed pressurized system by adding positive manifold pressure (boost) to both the fuel tank and obviously the air supply. And to prevent the post-sex dick dribbles: use a solenoid on a Hobbs switch set to ~5 psi to ensure a nominal flow rate is present at activation for the air supply.

Only catch I see is putting a solenoid in-line on the fuel feed to prevent unwanted fuel siphoning with manifold vacuum. Same deal as above.

After that it just adds fuel as the pressure rises.

That's a really cool idea man. I hope you try it just to get proof of concept because I think you are right, paying way too much for an under engineered system. I think you would be just as far ahead to put a cheap flex fuel pump in a 2 gallon fuel cell and tune a nozzle orifice for delivery. Still under the price point of an aftermarket setup and you probably have half the stuff to do it.

LOL - I do indeed. I've got a FF pump and a pair of 83pph injectors on the shelf just waiting for me to do something with them. Like buying these: https://www.efihardware.com/product...-Mount-Screw-In-to-suit-12-34-and-Full-Height

Very cool idea. I hope you can make it work. It reminds me of the old nitrous systems for the Turbo Buicks.

How environmentally conscious of you. 😉

MTO is an evil b*tch.

And with that in mind may I present to you: EMISSIONS!

A fully closed PCV system... and a retro-fitted purge valve. This was so painfully boring to do. But, all the check valves are in the right places to prevent pressurizing the crankcase... and use the turbo as a vacuum pump.
