What is more effective? Water/Air intercooler or water injection?

the water does not last that long on a "hot " truck. Had mine packed with ice and had most of it left after the pull. The intercooler was cold as heck after the pull major temp drop between end tanks, still working on a temp gauge thought.
 
Here is what i was told and my two cents. When i started building my 3.0 motor, i talked to Brad at scheid cause they sponsor my truck. I went into assuming i was going to run water injection. He told me the quit putting the kits on single charger trucks for 2 reasons, it takes away horsepower to trurn the pump, and they really dont flow enough air to justify the injection. Then i talked to him about air to water coolers, he said they run them on some trucks, but when they did dyno runs on the same motor with a air to air and air to water they only saw a 20hp increase with the air to water over air to air. He said he saves the money on ice and run an air to air and put money saved elsewhere. So there is what i was told and i am running a air to air with data logger. Now as far as controlling seperste cylinder temps, the water injection is the way to go. Im going to run this year with the air to air and if i see a big differsnce in cylinder temps i might go with the injection, but i just got done running my motor on the dyno and it seemed fine. Thata my .02 cents, sorry for writting a book.
 
For those who run air to water. Is there a certin boost level where your pump is powered. Or dose it run all the time? I would think cooler temps = spooling issues??
 
Water pumps should run all the time!

You may think it is a book but I like it and that is some good info!

Will you run say 2 huge fans across the intercooler to help dissipate the heat?

Well thanks Jim, i do think i am going to put a couple fans on the air to air as i do have 2 extras, so we will see how it works.

Ya, but if you want to be at the top, that 20hp could put you up there. Air to water is cheap horsepower if you ask me. After seein all the ITPA trucks alot of them seem to run pretty close together, and that 20 horse might set one of them apart.
 
20 hp on a 1200 hp is not as much as 20 hp on a 600.

So in a truck build, that you wanted to be one of the best. You wouldnt worry about that 20 HP??? Well I know who I dont want building me a motor Dan!!:kick:

True, but you could spend the $1000-$1500 elsewhere. Say roller lifters, better headwork.
 
My point exactly. And if i was going to build a motor for a guy i would do whatecer he wanted, but im pretty sure the extra 20 horse can be found elsewhere. Plus i dont thin the extra little hp would put you on top all the time either. But i guess we will find out, if im dead last all the time we might do something different!
 
Ya thats how Im going into this year. I hope it works well. But if it doesnt. I guess we will try something else haha!

LOL, ya it wouldnt be fun if you constantly have to be changing up something. I look at it like this, im running a high finnace class, i am doing everything i can to win, but if i dont this year, i will try something next year, im young, i dont need to be number one out of the gate, but i wouldnt mind it if i got on top a few times in the near future.:Cheer:

What is the reason for putting them on certain trucks? Im sure if these "CERTAIN" trucks can benifit from it, then everyone can? So what is a aftermarket air to air IC going to run u? If u have 1 then why not sell it, chip in a few bucks and u will have your air/water set-up. I dont care who ya are but 20HP is 20HP no it might not make u win by any means but if I can get that 20 u bet I will. What air/air unit did they use? What size charger were they testing with? Not saying they do cause it is none of my business but wouldent it be funny if they ran air/water set-ups on their trucks but told everyone else that u can do without??

I have run water injection and water to air - I am still runnin the water to air.

In my experience my truck didnt make any more power with the small single water injection, at least not seat of the pants feel anyways. Egts dropped marginally like around 50 degrees.

The water air intercooler with ice water made an additional 5 lbs of boost and egts dropped about a 100 degres

5lbs boost you can feel in the seat of the pants dyno.

What Water Injection System did you use for this test?
 
20 hp on a 1200 hp is not as much as 20 hp on a 600.

tell that to a superfarm tractor guy, they would laugh at you. evry little bit adds up 20hp there and 5 here and 10 there...... i would say that if they weren't worth having why aren't they allowed in the NTPA superfarm tractors
