Water for intercooler
 

Procharger M3SC with 504 intercooler. 540BBC shooting for 850 hp. IMCO shorty drive with low water pick up. Should I use the IMCO water for the motor and separate source for the intercooler?

Thanks for responses

Russ,
I use a transom pickup through a strainer, with a blow off valve. No cold water through it at idle, but when running it does the cooling. I have a larger intercooler and I was concerned that it might be too cold at an idle. At an idle is see 100* or more, at speed and 10 psi, I see 78* AIT.
Hope that helps.

Yes
Thanks

I use the std one for the engine they way procharger sets it up works fine for us...

Mr. Gadgets if Im understanding correctly you use use a pressure dump but rather than dumping overboard it dumps through the intercooler? no pumps?

I have a transom pickup, plumbed into a strainer. The strainer is then plumbed through the intercooler and it dumps over board. The strainer has a blow off valve that dumps over board as well, just incase I get a pressure spike.

Procharger's are the only setup that I do feed water to all the time. There are a few reasons for that. First, they use an aluminum core. I was always afraid to shock the cooler with cold water after heat soaking at idle. I don't worry about Whipple's cupro-nickel cores, but the aluminum Procharger cores worry me. The other reason is that the intercooler is mounted a ways away from the intake. I just don't think that you will have an issue with cooling the intake charge to much. Not to mention, the fuel isn't in the air charge when it passes through the intercooler, so you don't have to worry about it coming out of suspension. With a Whipple, you have the fuel being introduced in the throttle body. The fuel is going through a very efficient intercooler, which is right on top of the intake. If you cool it to much, you can bring the fuel out of suspension.In that case, I will force feed the intercooler with a transom mounted pickup so that it only gets water once the boat is on plane.

In your case, I would feed the intercooler from the crossover just like Procharger does it. I would monitor the intake air temps to be sure that they don't get to high. If they do, you may have to come back and add a pickup. However, I would only add it if it's necessary.

What are you guys running for IAT temp gauges?

I just monitor it on my laptop as I'm tuning. I don't think I have ever seen anyone with an IAT gauge in the dash. That's not to say that you couldn't add one though.

My buddy just bought these, I might pick up a couple too and mount them on the dash...

My name is I See Dead People ass hole!
Also I have that gauge for sale "used once" so its a good deal lol

I wouldn't want to admit who your buddy is either . :whistle:

You guys know I was joking right . Now back to the regularly scheduled thread .

lol , I know you were kidding, but it is true. :angry-smiley-038:

I kinda disagree, depends where you boat, I'm in Michigan and the water temp could be 75 one day then 55 the next. This was really a problem when I was carbed. . I would actually get puddles of water in the box from condensation....carbs would start rusting (throttle blades, anything made of steel). I went to transom pickups helped a lot with idle.

Thanks for comments, at least most. Ha. Cooler the better regarding the intercooler especially under high load. Correct?

I did something similar in my old boat years back. I had a vacuum/pressure switch that would close at 6 inchs of vacuum and stay closed thru the pressure of the supercharger. when closed it triggered a solenoid that allowed water to flow thru the intercooler and would go open again at 6 inchs for no water at idle worked for me at the time.

My buddy uses a relief valve too feed his intercooler. At idle, there is no pressure, so the valve is closed. Once on plane, the psi increases past his set 5psi, and water flows to the intercooler. His engine water psi is still good with this setup. Around 20psi of psi at the engine.

You are right, There is no "one size fits all" setup.I was speaking more in general terms. Also, I was referring more to an efi setup, like a 502 Mag or 500 EFI. They are certainly application specific.
