For those who have blow HG's, how many of you were running a programmer and what were you doing with your truck.

Programmers with advance timing,fuel, duration will raise presures more than 20% Water/Meth injection will.

Running a 20% water meth injection setup on a stock rig with very little modifications for towing should not be harmful to HG's at all. The problem is when people use water meth along with programmers (some stacked), twin turbo's or larger turbo's and various other mods and do other things like drag race and sled pull.

I think much of the problem with HG's is taken way out of context. If used as a stand alone or with minor mods, water meth should be a great tool for towing loads and keeping EGT's down. I know of a few guys, one running an 04 TCD and has put over 60k miles towing heavy using 20% water meth on the truck starting when it had less than 500miles on it. Never had a problem..

I think too many people use water meth for power in conjunction with other power devices in hopes to make large gains. My opinion is that it is what it states to be "a chemical intercooler" and should be used as such.

I plan to do a water meth setup also, but only after studs. Since i will be running stacked programmers and probally 100hp injectors. I would rather do head studs when i want to, rather than do a headgasket when i have to. A little preventative bombing goes a long ways.

BTW-- what kinda boost increases have people seen?

I LOVE my H2O/CH3OH system:



..... but I'm too scared to turn it on!

 

Many of us have been there. I started with straight water. Took me 6 months (and a lot of reassurance from Jim Fulmer) to work my way up to 50% racing Meth and feel comfortable with it!

According to Snow's, 3rd Gens get a lot more from it than we do. With your GVW and your stock turbo, I would think you'd really benefit!

Rowland, I'm at the point where I really need it - I can't go WOT too long with the Quad box turned up or the EGT needle winds right up to 1600*

Should the TIP rise when the H2O/CH3OH is activated? (because the methanol is combusting and some of the water is expanding into steam)

.... or should the TIP decline? (because of the methanol's charge-cooling effect, and the water's cooling of the combustion event)

I know the EGTs will go down, so that tells me the TIP "should" go down as well; but since I expect the intake boost pressure to rise as well - it almost seems to be a contradictory benefit.

Think this is a "quality of TIP" issue, like the "quality of boost" idea we discussed at Charlie's?

 

As long as you don't get detonation from the meth (my 2nd gen does not) I believe the TIP is directly proportionate to cyl. pressure/EGT's. Intake boost raised 2-3 psi for me, with a big single turbo. The potential for detonation is logical but does not seem to be actual... probably due to the H2O. Been told that Snow's 3rd Gen get 100 HP from 80% Meth mix.

I have never subscribed to the 'steam' theory as a problem because it is logical to me that steam formation only occurs as compression is decreasing... on the downstroke... and therefore after the fact. If anything...might aid cooling.

I do know that towing, or hauling heavy in the mountains, H2O/Meth is ALL beneficial....lowering EGT's, cylinder pressures, and I firmly believe... lower cyl. pressures/TIP.

What is strange is at WOT........ only thing I see is slower climb rate on the EGT's. Many others have said the same. If I stay into the throttle, the pyro will still climb to max levels, just at a slower rate. It's almost as if the H2O/Meth can't catch up. Back out of the throttle for a sec and than return to WOT, and the EGT's will level off and have a hard time continuing to climb????

With your TIP gauge, it will make an interesting test bed to see if we're right.

Has anyone put this on a 07 with a BDTD ?

 

the meth acts as extra fuel and the water and partly the meth lower the induction air temperture which raises the boost pressures because cold air is denser. Same theory in cold air kits. The horse power mainly comes from the meth and the cooling mainly from the water, although both help with the other one too

 

I plan on running Snow's stage 2 or a homebrew setup that I've mentioned previously on this site. The basic componentry of a water/meth system is very simple and cheap.

I'll start with pure water and slowly add increasing amounts of meth (blue juice washer fluid for me).

I'm not running a big fueling box, and I only see about 35psi from the stock turbo, hence I think water only could even be a bug help.

I know that a lot of the big pullers use TONS of straight water...

you have to use straight water if you run propane

 

Its not the water or meth that blow the head gasket. Its to much....Its nozzle placement and rate of injection. Remeber the intake design sucks, it was never designed to carry any type of fuel. I ve been using a stage 2 snow kit for a couple years at 60 psi on a stock bolts and stock 200k mile gasket. When I pull I run straight water, when empty a mix.

Im also doing another intake now to help the distribution problem and expect lower egts just with the intake, let alone with the kit on.

 

I'm gonna go out on a limb here and say that the METH wasn't the cause of the popped gasket when you're running 50-60psi on it!
