So I was looking at installing my methanol spray and this guy hook his up cheap style.

Basically hooked up a boost line to his tank to pressurize it. And I guess it pushes the water down. He uses a solinoid to open close the line that goes to the nozzle.

But it is interesting because he uses pressure to "pump" the water or meth instead of using a pump.

Anyone else does this?

Cheaper way but I wonder how well it works atomizing things.

 

It won't get enough pressure to atomize correctly spraying it pre-turbo.

 

How will it push out against the boost pressure anyways? If you put 15psi into a tank, then it goes out the lines to the nozzles trying to spray into the charge piping that has 15psi in it, how will it overcome the pressure? I for SURE wouldn't want to do it pre-turbo because the large droplets from such a low pressure system would eat the compressor alive.

 

I can't put the direct link cuz I'm not on a computer but here's the google link. 3rd video

And yea looks like a preturbo.

And I don't plan to iether I was just curious if anyone else does it this way.

 

will not be control able

 

That's how the Anderson Motorsports "Mr. Freeze" kit works. Or doesn't work... it's up for discussion.

 

Could the container that holds meth be pressurized by turbo ???
If container is up it ??

 

AFM Mr Freeze works that way, uses boost pressure to pressurize a container, then out it goes, via a nozzle straight on the center of the compressor wheel.

Install container lower so it does'nt gravity drain in turbo!

There is a check valve also i think so keep the motor from sucking when in vacuum.

As long as the Container doesn't expand under boost, it's ok.

Simple yet effective.

 

That sounds like a great way to eat a compressor wheel up.

 

Thats what everybody says but they dont supply pics to prove it.

My buddy has been running an anderson Mr.Freeze kit on his 306 SBF, YSI , 93 pump gas combo for bout 5 years now. Runs low 9s @150. We have talked about the possibility of the compressor wheel getting eroded. He says he has yet to see any problems.

I like the fact that there is no pump to fail. And the volume is variable with boost level. So if you come into low boost it wont cause a weird fuel curve by hitting the motor with the full volume. And you dont need a map sensor with a controller to get that variable volume.

 

Also a few water/meth kit makers also have the option to shoot before and after compressor, for better effiency they say.

 

i wished i took a picture on a caterpillar diesel water pump station , on a flood irrigation farm .
water was getting sucked into a turbo, was through a big ass aircleaner, the water leak was from a small hose running down the side of the pump station frame.
the compressor wheel was farked...
i just exchanged the turbo with caterpillar, and no repaired it, to get the engine going again, to irrigate the cotton crop

so yes, the liquid getting drawn into the compressor wheel wrecks shit.

 

Hi there,
I run two versions of this. Version 1 is on the race car 350sbc with 1000hp moroso. It has a tank with boost line running into the top and a nitrous solenoid at the bottom/feed end. The solenoid is opened by motec ecu at pre programmed boost and sprays pre turbo's via whirljet atomizing nozzles. We run water meth mix and have no turbo wheel damage to report.

Version 2 is on my 3TC street car recently dyno'd at 270rwhp. It has a similar setup to the race car except budget oriented i.e. gas system shutoff valve controlled by hobbs pressure switch and a donated snow performance atomizer nozzle. Since my streetcar runs on pump fuel not E85 I figure there may be less margin for error so I put the shutoff valve right close to the pre turbo nozzle and incorporated a non return check valve close to the tank to keep the system pressurized. This one too has yet to damage a turbo wheel.

I have tested both setups with the compressor at 15 to 25psi and the water meth mixture is quite well atomized i.e. no large droplets. To lean the system off a little in the top end over the torque peak if required a simple gas regulator can be put into the boost supply line to limit the total pressure supplied to a given psi figure.

Neither of these cars use any other form of intercooling.

Cheers,
Jason

 

How long have you been running it for? I figured with this I lt will damage over time if it actually does damage anything.

 

From what I understand large droplets can cause issues. If the mixture is atomized properly it does not.

However.

It may be that the diesel pump station had issues cuz it runs under boost and load for hours and hours on end. Ad the constant water going in the turbo and it speeds up the erosion process.

In our performance use we are feeding water/meth for short periods of time (11 sec or less) each time it used and may never come close to the constant load time of the pump station.

 

No erosion problems with my pre turbo injection setup with AIS nozzles. It doesn't even wear the marker paint on the fin I marked each compressor. The erosion argument is the same as running with no air cleaner. Short duration limited events won't usually cause an issue, but if you run an turbo diesel engine wide open for thousands of hours a year on a mining truck with no air cleaner it will erode the compressor and do worse to the rest of the engine.

 

Been running the water meth pre turbo for 2 years on the street 3TC toyota engine and only 2 months ago was given a spare atomizer nozzle from a local workshop. For almost 2 years I used a home made nozzle which was mostly just a liquid stream directed in the general direction of the turbo. I had no real care for the turbo as it was a junkyard nissan/garrett SR20 unit but there was no damage to the turbo wheel.

The race car has run the water meth pre turbo for a couple of years but it only runs for quarter mile at a time and few times a year! No damage as yet and we don't expect any for this kind of operation.

Jason

 

This idea is a very old one maybe 30-40 years plus. Remember reading about is 20 years ago in an old turbocharging book from the 70's. I have run many water injected cars with the sprayers into the compressor and the trick is to atomise first so the compressor dosn't cop the heavy droplets.
The pressurised tank idea can be a problem with the sharp boost rise on a low level of water in the tank when the water won't reach the engine in time to stop detination because it's trying to get up to pressure but you normally fit a solinoid to cut in at a higher boost point to let the water/methonol in.

 

How far is the nozzle from the compressor?
I have been reading up on this and seems like a lot of people are running it this way with no problem.(exept for one with bad placement)

I'm considering one preturbo to cool the blades and post turbo. But since my turbo has no pipe in the front or a filter just wire mesh i would have to spray directly into the compressor wheel. Just drill and tap the front of the housing. Will this cause a problem since my eBay gt45 has that anti surge looking design. And can I run this without a solenoid?

 

Water/meth injection was originally developed and used by the military on aircraft engines that where supercharged during WWII. 1940s

Kinda funny. They used Nitrous too.
