Plumbing Intercoolers?

[P-Money]

Before I start drilling holes in the boat, I just wanted to get some opinions. What are the advantages/disadvantages of the following options when to comes to plumbing an intercooler for a v-drive application:
#1: Force feed the intercooler with a pick-up off the cav plate to a Sea Strainer, then to the intercooler and finally dump out both sides of the intercooler back to the river (ie: force fed seperate system).
#2: Water pick-up to a pump (neovane in my case), then to the intercooler, then dump from the intercooler into the motor, and then out of the motor back into the river (ie: this system would NOT be seperate and would be pump fed). With this option I've heard keeping an eye on water temp will clue you in to when the core is becoming plugged.
What do you prefer/recommend, #1 or #2? Any opinion or experiences would be greatly appreciated.

P-Money,
I would go with option #1. I use that on my 502 w/Whipplecharged w/intercooler.
I use -10 lines on both inlet and outlet.
The inlet is a dedicated pickup on the bottom of the hull. I dump the water out a -10 fitting on the transom. A pickup on the cav plates would be the same deal.

I hooked mine up the way PFM recommends, separate water pick-up to a sea strainer then to the front of the chiller ( -12 hose ) Pressure regulator set at a max of 30 pounds. One -10 hose for the exit at the back.

I use -10 everywhere. pick up in the bottom of the sponson toward the rear on tunnels or on the transom in "V" hulls. pickup to sea strainer with relief valve - to intercooler - to oil cooler then -10 transom dump.
lets oil get up to temp and does not intercool at idle.

All good advice. Don't run water through at idle. When the fuel passes through the inner cooler (at idle) it will slow down, allowing the particles to join. This will create puddles and uneven fuel distribution.

[P-Money]

Thanks for the advice everyone. I was leaning towards Option #1, but just wanted to make sure before I moved forward. Thanks again.

P. go -16 pick up to strainer to pump -12 min, better to go -16 reduce down to -12 at intercooler, then to -10s into motor then out exhaust or boat. A quality intercooler will have a -12 in and -10s out and no pressure reg, don't need one. I have tested my intercooler cores to 235 psi, no leaks. Going into the motor will let you know when the intercooler starts to plug up, cuz the motor will start to run warm, better then waiting till your motor starts detonating and kills it self little by little. One other way to go is to put a psi guage on the inlet side, and check psi at 1000-5000 rpm range and check guage every so offten. Set one up like this, works well....John

Well I guess that would depend on the intercooler design.
The Whipple ranks up there with the best. An intercooler that is "in manifold" has "O" ring seals for the water fittings.

o'ring seals for water fittings. A lot better than NPT. thats why i designed mine like that.

J540, Do you make a core for the Super Chiller ?

[P-Money]

J540 has his own housing and core. I just got one. From what I've seen with my own eyes and heard from others, his product is superior to a Superchiller.

[Infomaniac]

That's great. Let see some specs. and pics.

[P-Money]

You'll have to get all the specifics from J540, but here's what I can tell you. The core is somewhat similar to a Richard Lee, but is 2 rows wider. It has -12AN inlet and four -10AN dumps (that way you can plumb it a variety of ways). The housing is a little taller than a Superchiller. When I got it I held it up to the light and you can't see hardly anything shining through. Superdave 013 discussed the cores a lot in a topic entitled "I'm cooler than you" Not sure if you remember that one, but its gone now (lost during the update of the website). Nothing against Superchillers, but as with everything, there is always something bigger and better out there. I've heard things about Superchillers and pressure that make me nervous. Here are a few pics:

As soon as i get new pushrods for my motor,i hope to get over to dyno in next 1-2 weeks , then can give you some #s. have one guy that ran 148 deg. water into the intercooler 5psi.boost 14/71 93oct. 112HP gain, verse no water going through it. want more info call me.

J540- I was thinking of taking 3 of your intercoolers and stacking them all together-Will this help. You BIIIAAATCH...
On a serios side his intercoolers look bitchin and he is in the process of fabricating a billet intercooler and also a sheetmetal manifold that incorperates a billet intercooler built into the manifold. That will be a bitchin setup. His cores are similar to a lee unit but has a bit more height and has an extra two rows of fins. His coolers have alot of design built into them. Like putting a radius on the top of the intercooler to give access to a few more rows of fins-which would equal more cooling and less restriction. If anyone need a cooler give John a call. He can give anyone a unreal price since he does not yet have all the huge overhead, Yet. KELLY

The best thing about John's coolers is they come with a FREE belt AND pulley if you want to increase the boost. He will come to your house and help you install it too!:D :D

[Infomaniac]

Put me down for 4 of them. :D
I will PM you directions to Oklahoma.

Just filled up the Excursion with diesel,, where's those directions,but just to let you know i charge 50$ more for out of state delivery.:D :D

With the size of the scoop on your hatch you can get 6 min, under that thing:yuk: .and dont for get the ( cupronickel ) intercooler core coming out soon.

Not gone, I just bumped it and another old one.
Search doesn't work, you just gotta find em. Blower section isn't that big so it was easy.
