Default Crazy idea? use boost to inject meth?

Was just thinking. For a super uncomplicated added boost in cooling, why not get a sealed tank, at the top run a boost pressurized line from the turbo and then the outlet of the tank run to a nozzle pre turbo. yea it make not inject as much as a pump, but use a little bigger nozzle but only use this as a supplement to help cooling...not rely on it. would be super easy and cheap. dumb idea?

Well I think a typical meth injection pump runs around 300 psi and you'd only be getting 20-30 using the turbo so the atomization of the spray may suffer?

True. I didnít realize they used that much pressure especially when Iíve been considering doing it the homemade way using a washer pump. I didnít think a washer pump put out much pressure. Iím gonna experiment with nozzles this weekend on the bench and see how much flow and atomization I can get. I was only considering this for now as I figured something better than nothing until I can afford a real kit.

Did a little research on this myself: https://gbodyforum.com/threads/copo-....61336/page-44

Congratulations, you just invented a carburetor. Unfortunately, your design does not sound like it would work as good as you would like without additional one way check valves. While you do have a workable idea, I do not believe it will be as simple as you would like. Don't let it stop you from experimenting.

It's been done before, and was in threads I posted links with previously. Most important part is a low pressure atomising nozzle.

And no, as long as the water tank is lower than the nozzle so it cannot gravity drain no check valves are necessary

I would not be concerned about gravity drain, but rather using fluid from the air across the nozzle in the same manner as a paint gun or carburetor works.

Has been done quite successfully many times. As stevie mentioned, the key is to get a good atomizing nozzle that works at low pressures.

It's probably most atributed to a rotary guy who goes by "rice racing". By all accounts, he's a complete ******* of a bloke who sells over priced kits, but he does have some good info out there.

an old friend had a setup i thought it was called mr freeze, but it used boost to pressurize a tank that sprayed at the inlet of the centri blower. there was concern that the fluid hitting such a fast moving blade would eventually erode it.

zero concern with the correct nozzle.

Thats what ive been reading. no one has actually experienced blade erosion. I mean they hey ran draw through carb turbos for years with no issues. Myth? I think so. And even if it does, by the time that happens, it'll be time to replace or rebuild this china turbo anyways lol. Blade erosion is the least of my worries.

If you want to worry about blade erosion...run no filter or a turbo guard..then you;ll get blade erosion lol.

I did this a while back on one of my supercharged 3800ís. It worked but it was very inconsistent and overall not worth it. My $.02

Can you elaborate on what you did and how it was inconsistent? Iím curious.
