What to do on super chiller
 

I'm having a 540 or 572 built for my 26 eliminator Daytona. We pulled the old engine out and it originally had some good parts but I'm not gonna cut corners like they did (long story) . What I need to know is what to do with chiller . Should it be ran on separate pump or off engine?.. Or is there a big sea pump that can push the heck out of water. I have one pump now and it feeds everything including the b-max outdrive too I think .

Just use a separate transom mounted pickup that force feeds the intercooler. It doesn't have to be hooked up to a pump. It works on water pressure alone. Works great. That's how we do every one.

is there a better pick up? I always thought those things scrubbed a bunch of speed.

come over and look at mine,when the bottom got blueprinted they added tunnels for the water to flow through.the pickup is not hanging in the water.

Like Mike said, if you do a lead-in in the bottom, the pickup doesn't actually hang down below the bottom.

Here are a few pics of one that I did recently. These were for an intercooler pickup.
Eddie

Wow that is really bad ass!
Mike I will have to check yours out, I`m assuming Nabbers can do that no problem

yes,he did mine.they do really nice work,i had them do a transom for a boat i was working on and it came out much stronger than origional.they also do nice paint work.

Nabbers did the lead-ins for Louie's Donzi. He also blueprinted the bottom. He does some excellent work.

Good to know..
What about utilizing my current pick ups and taping the chillers off the existing strainers?

Excellant question, looking forward to the answer on this one.

You will have to be sure the fitting in the strainer going to the intercooler is below the water level in the strainer so the pump doesn't suck air at idle. You can do that as long as you have a sufficient amount of water volume feeding the strainer. I've done it in the past and the only issue that I had was that there was some water that flowed through the intercooler at idle. I guess there was a small amount of pressure in the strainer at idle so it forced some water through the cooler. I wasn't crazy about that so I just add a separate pickup.

Cool thx. Also is there a better belt driven pump for more pressure and movement of water. This is a roots blower so I don't want any heat problems at all. Also this might be a dumb question but what about two oil coolers instead of one since the oil gets hot as heck in a boat especially a blown engine.

I like the tunnel idea and we can do that at my shop. I do that fiberglass for a living and paint boats, working on a 44 mti right now that got hit by a sign. I own fibertek marine on grand lake.

There is no need to go to a 2 stage pump unless you have a pickup larger than 1 1/4". It won't flow any more water. The Hardin pump is a nice piece. The water passages in and out of the pump are larger and smoother for better flow. I'm sure one of their pumps will flow more water than a Merc pump with a plastic housing.

Negative on the 2 coolers. One larger cooler will be more than enough. How much power? If it's less than 1000 hp, an oil cooler with a bundle length of 3" x 18"-20" should do fine. That's not the overall length, but the length of the bundle of tubes inside the cooler. You will need an oil thermostat or you will have problems making enough oil temp.

Ok I have all that . I believe it's a little bigger also. So good news I guess. I used to drag race with the I.h.r.a. And learned a lot from those guys but this boat stuff is a little confusing. I bought a callies magnum Xl. And want to protect it the best I can if you get my drift. Expensive but the crank is nice enough to hang on the wall.

Thank you for the info Eddie , very informative as always!
Btw , got any whipple intercooler cores laying around you wanna get rid of cheap ??? :drool1:
I`m starting a new intercooler charity...its for the CHILDERN.. mine wanna go fast!! :santa:

I had a few of them but I recently sold them. You are about a month to late. I can certainly get you a new one less than anyone else. However, I will keep my eyes out for a used one for you.
Eddie

Eddie, Icdedpeepees picked up some Lee intercoolers, with leaking cores. Whipple makes a core for them don't they?

I sent Eddie a PM Mild Thunderer with that info :bunnydance:

All I got for you is if you ever go in salt warter.... every time you stop or go slow. All of the water runs back out of the cooler and it will be dry , (saltwater damage happens to do the most damage in the first moment is is dryed off.. Probably what those coolers you have need cores). you might be able to check valve it. But check valves can leak and cause some what a restiction. If you run carbs, seperate pick ups are your only choice. IBut if you have fuel injection you can run off the pumps and save bastardizing the hull of your boat. . .. Merry Happy Holiday's !! :D

It's a pretty small hole on the front of the drive to feed both
You'd have to put a check valve in line so the pump didn't draw air from the IC

Eddie-Did you just grind it out and spray on gel-coat? Or, did you add glass back then gel?

you would be suprised Rob. I have the same base Mootors as you, but sportmaster drives .. 10-12 psi .. 8-10n at cruising. Id have to look for a check valve but i donth't think so ..Chad

Here is my pickups. Does taking in water from here cost top end. how much speed are we talking? Thanx for the info. Much appreciated

You'd only need a check valve if you grabbed IC water ahead of the pump and dumped IC water above the water line.
The Sportmaster has some nice PU's. My IMCO SC's only had one hole.
I still question feeding the engine and IC through them. Not only the PU holes but also through the transom assy hole. What's it, about 5/8"?
Trying to feed 1.25" engine hoses and -10 IC hoses with the transom restriction is something to ponder. I know it works, but I still ponder.
Other ponderings;
How does a 3/8" line hanging off a rudder cool a P/S boat?
Why do I need 1.25" through hull PU's to feed the 1" ball valves to feed the 1.25" strainers and raw water pumps? esp when it all came through the 1/4" hole I the drive bullet before?
If I installed a 600 gallon auxiliary fuel tank, how long would it take me to go from SF to LA?

pressure and volume.Kinda like a Prostcock hood scoop. Notice they are huge w a small hole.. Less area to crab air and cause drag.. Presurze a large hose for volume with a smaller intake for drag. hope that helps

I totally get the pressurization. Why run 1.25" through hulls if 1/4" was fine before?

I found a local place to rebuild (take out the entire middle section that leaks and just reuse the ends) for $1000. They say couple more hundo and they can make a brand new core.. I`m dying to find out what it comes out looking like cause CP wants $2400 for a replacement core.:rolleyes: Its basically a radiator so i`m not sure what magic you get at that price..
Oh wait I just remembered .. ITS FOR A BOAT! :angry-smiley-038:

People say B.O.A.T. Bust. out. another. thousand. However . This is a wrong statement in our world.

In our world it is ...Bust. Out. Another. Tenthousand .. right ? :D
