im sick as hell

[newmexicoviper]

Now this is just an idea for you to think about.

I ran methanol injection on one car I had that ran up to 40 pounds of boost at times. I had an adjustable pressure sensor in the intake manifold that triggered the pump motor to inject the methanol that was set to 10 PSI. Very simple and it never failed.

Sometimes simplier is better.

Ill go back to what uncle sam taught me KISS, Keep It Simple Stupid!

sean , thats close but to be totally accurate, I PAID FOR THE SYSTEM ON OCT 30th , but it was not delivered and installed until about 3 days before thanksgiving.And the truck ran up to about 115, I didnt see any smoke, it just started skipping, when we stopped, we saw meth pouring out of the filter. idling in the yard, is when the yellow engine light came on.IO tried to retrieve the code the same way i have done on other trucks, by turning the key on and off several times but nothing came up after several attempts.when i called you sean, you had me check the vacumn hose while you were on the phone,we discussed drying what we could out, and letting it sit for a few hours. you told me that it was hard to believe that much could have went into the motor.and i called you when we tried the system on woodys truck. but any way, you said to let you know about writing your claim, by the way sean, i pulled the engine out this afternoon, i will take it down in the morning. anyone know what scrap aluminum is going for?

Hi Mark,
Ok, it’s probably best if I leave out the MPH part and just say it started skipping.
I do still find it hard to believe that so much water from the WM system went into the engine that it hydro locked and blew apart.
The nozzle for the WM flows 7 GPH at 140 PSI in a very fine atomized mist. You said that there was a lot of water running out of the filter, which is good in that it means that at least that amount wasn’t going into the engine. That all makes good sense as the throttle body would be pretty well closed most of the time. Any condensed mist that got past the throttle body would then have to go through the screws of the supercharger and down that air flow path (back to front). There’s less than 0.005†clearance between the rotors and Supercharger has an internal compression of 1.4 bar. Any water would be pretty much vaporized during that process, especially when you take into account the heat inside the blower and intake manifold. Add to that the RPM of the engine and it would be pretty unlikely that there would actually be water so condensed that it had time to run past a valve and partially fill a cylinder.
I think that the incident with Prof and TNViper, especially where Prof’s ran the system until the tank ran dry, but still didn’t hydro lock the motor adds a little validity to my statement that I’m surprised that much water went into the engine.
Keeping in mind that the motor blew up after you talked to me and ran it later, the only valid reason I can suggest to be water related is that perhaps over the course of the time the engine sat there, the water vapor inside condensed. However, that doesn’t make a lot of sense either since the motor was hot.
Could your head gasket have been leaking? Tator’s Dodge in NY had to put a new motor in a Ram SRT-10 because the head gasket failed and took out the motor.
Look at the head gaskets very carefully as you disassemble the engine.
Also, I assume you saw what I said about my VEC supplier statement. They will not help me to help you unless they can verify there’s a fault in that box which causes the PWM output circuit to come on and stay on.
Since you’re asking me to trust that all this is due to something that came from my shop, I need you to trust me and send that box so I can have it checked out.
Regards,
Sean

I have a "light" on my pillar that illuminates when the meth pump activates...I might add a beeper or buzzer just to make sure it gets my attention..

I mentioned this before and will do it again as a reminder. When you are driving your truck, whether it be on the highway, road course, drag strip, whatever, that little light is not gonna be on your mind. You'll be so focused on traffic, other cars drag or road racing that it could be on or off and likely you wont notice. Even if its on or buzzing or whatever, that isnt a 100% guarantee that your meth injection is running properly. Its just telling you the pump is on.

I had a VEC program that disabled the meth injection for road race applications. The last thing I need to worry/think about when road racing is constantly checking the pillar (and taking my eyes of the road and traffic around me) to see if the light is on.

My answer to "should I still run the Roe supercharger without the meth"...yes you should. The supercharger had nothing to do with the meth injection pump. After reading Roe's response to the amount of water, it does make sense. That nozzle is very small and would take a huge amount of water (the nozzle shoots a mist) to do the damage as described. Mist and water just dont jive to me as being the same, kind of like drizzle and rain. Its takes a lot of drizzle to measure .01 in a rain gage where a little rain can do the same in a shorter period of time.

Maybe something else is going on and hopefully the tear down of the motor will tell the story. Be sure to takes lots of pictures as you tear down the motor so you have a chronology of how things looked as you first unveil them in the tear down process, kind of like peeling an onion. As you peel away layers of the motor (intake, heads, etc) take pics of what you see and pass them along to Roe so they can see the same thing.

Good luck!!

FYI. My tune has the Methanol pump working at 93% of its capacity at 5800 RPM.

im out on the meth without a doubt

I'd check and see if you nozzle came off. You might have then been pumping a water stream into the throttle body instead of a mist. That's the only way I could see a higher volume of water getting in.:dontknow:
