Heat Exchanger for 454

[Bigblock]

HI
Does anybody here run water water heat exchangers to keep there engines cool?
I am interested in the setups peps have and places to purchase them.
Any help would be much appreciated.

Cheers

Well, here's one source for heat exchangers, I ride on the biggest radiator (lake/river)for free so I just use it!..:D

Thanks River Racer
In Oz, with the drought having a firm hold on our dams and river systems there is a lot of weed and mud that can be sucked through our engines and cause all sorts of problems. The dams are not a big prob but the rivers are not good at all.

Those exchangers you linked me to are a bit to commercial looking for me.
Any info on hooking them up and peoples opinions on the best way to run them would be good.

Well, still gotta be careful though the motor won't have a problem, but you still have to feed the heat exchanger and you can end up plugging up the exchanger with garbage and be in the same situation as if you didn't have one. Myself I'd save a bunch of money and just use a sea strainer, it captures all the garbage just check it often and keep it clean!..

Sea strainer.
I will google it and see what i get.

Thanks

Seems to me the "easiest" way would be to install a strainer... and flush the motor & drive when you bring it out.
If there is a worry of mud building in the bottom of the block... just install a "back-wash" connection to the lower block area using the drain points... either side. Just make sure if you are running wet headers... install some way to close those off... valve works best before the T-Valve. Getting mud built up in the header injectors can be a real pain in the butt to take out and clean... :)

Ok strainer will be the way to go. $400 is better than a $1200 exchanger
I can still run my hot water out the side.

I got one of these from Rex Marine

Those are oil coolers not strainers!..:D

Run the water through the strainer before the pump and it'll keep all the garbage out, just remember to check it often if you run in dirty water a lot!..:D

Hi there Bigblock, just got onto this thread! Try the ski race guys down your way, they run all sorts of things... I am going to run one the dan olsen oil coolers and warm the COLD water from the river before it goes into the engine. That way I am taking some heat out of the oil (heat is oil's worst enemy) and pre warming the water going into the block so there are no cold spots in the engine.
What size big block and in what boat? Just being nosey!
Cheers:D

[raysoninoz]

oops just read the title of this thread! :o Disregard the first part of my Q!!!:rolleyes:

(heat is oil's worst enemy)

Only after a certain temp, it's gotta be at least 185-210 to do it's job!..;) But you're right, always run the water through the cooler first that way it takes the chill out before it goes into the motor!..

Thank you for adding that bit about the oil :o, but I wonder why the need for a heat exchanger unless the cooling system is a closed/sealed system and the engine is running unusually hot. :confused:
Most heat problems in vdrive boats are from either lack of water going through the motor or water moving through the motor too fast that it (the water) cannot do its job ie remove heat.
Bigblock, what are you doing with your boat? River rodding, ski racing???

Hi Raysoninoz

Just recreational sking and some drag racing
I would like it for 2 reasons.
1st is to keep my cooling system nice and clean.
2nd is to have a better control of my water temps.(sealed unit)

I have some mates who run drag only (1k Hp) but also want to take them up the lake for a flog. They are very interested in the exchangers for temp control.

Cheers

Sorry but a sea strainer won't help control your water temp!
As for drag racing a lot of guys have trouble getting enough heat into the engine before a run. Some run billet heads - no water at all. Some fill the block with coolant, heat it up and get temp into the block, make the pass, then drain the coolant. I took the povety pack option and just restricted the amount of water entering the engine, and kept an eye on the gauge.;) After all it's only 1/4 mile...

Well, since the lake/river is the biggest radiator you could get you won't have trouble keeping it cool from flow, it's different in a car with a radiator and no thermostat, the water don't stay in the radiator long enough to get cool so it eventually over heats!.... Myself, the only reason to run a heat exchanger is if you run in salt water all the time, I'd just use a sea strainer for dirty water!..
