So if your annalysis is correct, then why does it matter if you run water on the dyno, if it doesn't directly make HP only indirectly. I'm sure that if you run a motor up to 1800+ degrees for just a short dyno run it wouldn't hurt would it? I've always thought it would take high temps for an extended amount of time to harm an engine. But maybe I'm wrong.
So what I'm trying to say is that if a truck can make a certain amount of HP with water on a dyno it could also make the same amount without it. It would just have less than acceptable EGT's. So is water really considered an additive? Doesn't it server the same purpose as an air to water intercooler, or something to that effect?
Just wondering, not trying to ruffle any feathers.

SEOHPowerstroke and muddin_dude 06:
I wanted to get on here and explain to you guys the situation with my water system along with power gains, EGT's etc.
As "muddin_dude 06" pointed out, right now I am running a Scheid Water Injection System that utilizes nozzles which go directly into the cylinder head, much like a nitrous system would be plumbed up on a gas drag car.
At present I have five (5) nozzles. Previous to this, I had a Snow Water System with two (2) of their 625ml nozzles going into the air horn. After Scheid rebuilt my engine last year, we found out on their engine dyno that there was no way the Snow System would provide enough pressure OR water to keep my engine cool. Thus, I changed over to what I have now and am very, very happy with it.
I DO NOT run anything in my water tank other than straight distilled water and an additive by "NAPA" (Number 13) which is a lubricant and an anti-rust preventative so my cylinder head will not develop inside rust. This was witnessed by Lloyd Mills among others at our recent Durham Dyno Event if anyone here doubts that. I CANNOT run methanol because of the "mechanical or fixed timing" on the Cummins 5.9 12 valve engine with the P-7100 Pump! I know because I tried, and with the methanol and high timing I run I had "detonation" at high RPM like you would not believe!! You can however, run methanol in the "variable timing" Dodge CTD 24 valve or even the Dodge CTD CR Trucks with no problems, but in my 96' Dodge CTD 12 valve with the P-7100 Pump, I do not recommend it!
With all that being said, I have made numerous dyno runs WITH and WITHOUT the water on and I see NO DIFFERENCE in my power with the water on or off. There is alot of "controversy" about water injection with many saying that the water is a "power adder" because it keeps the engine cooler much in the way you described above SEOHPowerstroke! As you also said, while I "make the same amount of power with or without the water, my EGTS WITHOUT the water are literally "off the charts!":hehe: I know that when I had the Snow Water System and tried the water/methanol, I did see a power gain of around 50 H.P. with the water/methanol ON! But as I said above, with JUST distilled water and my additive I see NO H.P. Gains!
I am amazed that the high power CR trucks can run like they do without using any water injection. I know that Tim Barber had a Snow System on his blue 2006, but don't know if he will run it on his new 2004 project truck.
I hope that this has helped you guys to understand it a little better! I didn't mean to "hijack" this great thread on the "Highest H.P. CR Truck" but I wanted to clarify the water issue since it was brought up and my name came up.
Lastly, I was at "Fall Brawl" and finally got to meet and see Lloyd Mills run his truck! What a great guy he is and what a damn powerful truck he has! Lloyd, congratulations again on all your great numbers! You and Tim Barber are the best and I look forward to seeing you guys at some events this upcoming season! :rockwoot:
Take care guys!
