Hi Guys

1. What are the dangers of this Water/meth kit? ( I would mostly want it for cooling egts but I also want a safe performance gain)

2. How fast does the small tank go empty?

3. Would their be a way to mount the big tank on the frame?

4. What kind of performance gains can I expect while running it in a safe manner?

thanks,
Andrew

No danger if you run water only. The danger increases with the % of meth you run. Yes, you can mount any tank you want that will fit on the frame. How fast you use water depends on what size nozzles you install, how many of them you install and at what pressure you run the water pump.

The benefit will be reduced EGTs. For towing heavy keep tuning the water until it just starts to quench the fire, then dial it back just a bit so it doesn't affect flame front propagation and you will have as much EGT reduction as you'll get with water alone.

40% meth gets me 40-50 hp on the dyno, that all I will run with my rods. I have a 8 gal tank in the tool box and it lasts me about 500-600 miles...

cooling mist seems to be a nice kit. i will be putting on a kit very soon and plan to do a write up, but i dont think it will be cooling mist kit, more like the hypermax kit. i plan to use it for cooling only.

andrew- do you plan on spraying it all the time? i guess it depends on your goals. do you want it boost activated?

Hey Mikey

What made you decide on a hypermax kit?

I would probably being spraying it most of the time. Yes I was thinking about boost activated or maybe the daul controller so when towing I can set it for egts. I was thinking having it engage at 8lbs. How does that sound? When Should it be turned off?

Would their be any danger running it most of the time with enough meth to make 40-50hp?

thanks,
Andrew

Mike make damn sure you also put a pressure switch inline with the EGT sensor for the on/off. I have seen his kit keep spraying after you get off the pedal with high EGT's. Send a PM to pwersnorter, and he can fill you in on the # of times he has hydrolocked his motor with it after a pull.

Andrew, that is what I am going to be running.

weird...zane runs that kit every pass..no problems as of yet and i think it has like 100 passes on it... if i dont go hmax i will go to the egt activated cooling mist kit .

p.s. mark you may make more power but you will never be faster.

Mike, for drag racing you will be okay, the motor still has RPM at the end of the track, when used in pulling, you come off the throttle and go damn nere to an idle real fast. That I why I suggest the pressure switch. Forgot you are draggin mostly.

My sig does not say ANYTHING that is not true. JK little bro.:poke: I do have less HP and I am slower.

Mine is set to come on first stage at 8 psi and second stage at 13... I run water most of the time but 40% meth for events... Mine is on about 90% of the time unless I am pulling and dont want to eat up my water for no reason... I would run a boost only kit, if your not making 8 psi then you should not have high EGT's...

Every one of the Boost/EGT kits I have seen never work right...

Running 100% water does more than just cool egts. It moves more air :eek:

With a truck running serious boost pressure, you can expect some also serious increases in intake airflow when the water kicks on and a power increase on water only because of the intake air cooling.

Anytime you cool the intake air post-turbo you have to then draw in more air to the compressor inlet to maintain the same manifold pressure you had before you sprayed the water into the less dense intake air charge.

Nobody ever looks at it like that. But intercoolers and water injection Move more air. A non intercooled non water-injected system moves MUCH less air than the same system with a cooler and water injection.

Cooling the intake air charge increases the volume flow through the engine. The higher the boost, the more pronounced it will be because of the higher intake air temps for the water/intercooler to reduce and the subsequent change in intake air density to follow.

ive heard that before charles. i'd love to see some data comparisons of boost pressure and hp. it would be interesting.

It's the exact same reason that you can take a stock turbo off of a truck screaming at 40lbs of boost, toss on an H2E at 30 lbs of boost and make so much more power.

If two manifolds are both at 50psig and one is at 500 degrees and one is at 120 degrees, the one at 120 has a whole lot more air mass than the one at 500 degrees. The ambient air is at a given density, or mass per cubic foot. So the only way to get more air mass into the manifold is to have compressed more cubic feet of ambient air into that manifold.

That's how you move more air at the same pressure. Density is the name of the game. You can either squeeze it (boost) or cool it (temperature) but either way, you're just making it more dense. More O2 for a given space to burn.

When I see pulling trucks with compound turbos and no form of cooling whatsoever (no water, no cooler) I just shake my head.

To put it into perspective, you would need to run on the order of 140lbs of non-intercooled boost to reach the same airflow as around 80lbs of boost that was well cooled with water and a water:air cooler. Which would the engine rather get?

:D

I have 0 added HP on the dyno at my power level with just water... Dockboy say he saw about 10-15 IIRC at his 550-600hp level, very small...

But I agree, cooler is better...

Any problems running water/meth with nitrous? I plan on running a water kit sooner or later, but not sure how the meth would work with nitrous.

I have heard several people doing it... Dockboy was running both, but I dont know if he ran them at the same time... I cant see why, in a built motor, it would be an issue... Might need a better tuner then the one you have listed... LOL J/K

I mostly want a kit for egt's just using water while towing, but if figure if it's on there when I'm on the way to the track.....

Man, water is like Nos I guess, once you start you cant stop... I go thru 5 gallons of meth a week... DAMN, That sounds bad...

this is why trucks run better at Baytown (sea level), then in Bandimere (5000 Plus) . Cramming more oxygen with the same set up, Rite?
