Alternatives to Procharger intercooler
 

I have 350 mags in my boat with procharger set-ups on each engine. I have a small leak in each intercooler so I have to replace them. The issue I'm having is that procharger intercoolers when used in salt (I leave mine in a weekend at a time) will supposedly rust out in a year and they cost $1250 each to replace. I was wondering if anyone has run the prochargers at a lower (3.5 psi) without intercoolers? Alternatively has anyone used and alternate intercooling method that will withstand salt water running longer term? Is anyone running air to air? I really like the way the boat performs with the chargers and the fuel efficiency they provide with a lots of power on tap. I'm not interested in building 383's or other performance small blocks as I really like the idea of being able to replace an engine fairly inexpensively should one fail. Thank you for any info you might have.

What about a water/meth injection setup? I run one on my turbocharged LS with no intercooler and it works great.

I was wondering if that might work. At what pressure would you kick it in? What size nozzle would be appropriate? I would think a large tank would be needed.

call snow performance,they can help you with the proper setup.

Your going to need a large tank for that as a boat is under load all the time unlike a car that doesn't have to be in boost at all cruising. Do a search for killer chiller setups.

is there a way to flush them when you get back to dock after running?

Agreed. I have this system on my cobra and love it. Make sure you spring the few extra bucks per system and do the variable boost referencing. It adjusts the volume per the boost level. This will save you a lot of juice. You can buy the boost juice from snow or just buy methanol and mix at a 49/51 (non flammable mix) with distilled water. 49% or less meth with 51% or more water. Build or purchase yourself a good size tank and hook up the low level warning light. Sensor will come with the kits

I have my setup turn on at 3 psi. I'm running dual 10 gph nozzles with an 80mm turbo at 15 psi. Depending on your power level and boost, I'd maybe start with a single 10 gph. There is a calculator out there on Devil's Own's site.

Depending on how hard you're running for how long, I'd think that a 3 gallon tank would be plenty for a day on the water. I always run -20* windshield washer fluid which has about 30% meth 70% water.

Any alternative intercooler thoughts? Water meth is a good solution but I don't particularly like the thought of having more fluid tanks to keep full. Water meth can also effect the engine tuning too. Has anyone tried air to air intercoolers on a boat before? What about a replacement intercooler from an aftermarket supplier like Frozen boost?

Give Dustin a call at www.whipplesuperchargers.com. All of their intercoolers are made of cupronickel and salt has little to no effect on them. They replace or sit under most manifolds.

Meth is the answer, it will make your motors so happy and last longer!! Talk to Rodney there he rocks!!!!! :-) :-) They have some new tanks not on web page yet they are Awsome and have all the right baffling in them for a boat :-)

Air to Air would work if you could get the air to it. Don't know if R-Tech is still around, they were making intercoolers for that application.

I'm familiar with the Procharger intercoolers.
I could make up a core unit of finned cupronickel tubing that would fit inside of the housing. From the outside it would "be" a Procharger intercooler, but all of the water passages would be corrosion resistant cupronickel. The housing of course would still be aluminum but would only see hot air - not water.

The finned cupronickel tubes could be stacked and staged to allow the coldest water on the "exit" end of the airflow and the warmed water to exit on the entry end of the unit - this would spread the cooling delta all the way thru the core.

I haven't done one of these, but I would say I could do so for no more than the cost of a standard replacement unit.

That sounds really interesting. I sent you a pm.

I have one of these setups on my Grand National, and run it with straight Methanol. You will be able to turn up the boost if you so choose to do so and still have a huge safety margin. Methanol is cheap and you don't use a lot of it either.
Their system is totally programmable, and only come on when you need it.

got a friend that ran one of thease in his zx for a few yrs..worked gr8..http://www.frozenboost.com/index.php...0a99242d95ac1b

They look good, thanks for the link, Fixx!

Fixx,
Was he running one of their intercoolers in salt water? My boat goes in for three days then comes out and gets flushed. The frozen boost stuff is inexpensive but I worry about longevity.

salt and aluminum are not going to be good no matter who makes them...

noi fresh water..im suprised your having trouble,,trailers seem to last in salt water..you may want to rig up a flushing t in the sostem to flush the cooler when sitting..i think the problem come from the boat sitting and when the water drains out on the cooler the salt in the water plugs up your cooler and then starts to rot it out..call frozen boost and see what other options they have..you may be able to run the cooler through a ice/water tank but dont know how long the ice / water will last in the heat..http://www.frozenboost.com/product_i...0a99242d95ac1b

im thinking a on board liquid nitrogen tank cooling the water for the intercooler might work.

Btw
 

you want the intercooler that reads 150 psi,,,these coolers are alot thicker so they wont rot out as fast and may last alot longer..i have a ? do you have a pressure relief valve? you may have too much water pressure and may be blowing holes in the coolers

Check out Rtech,

When installed on a boat in exchange of the stock intercooler they were getting more HP. When I put one on my boat with a m4 procharger the FAST ecm & O2 sensors required 15% more fuel, due to the cooler intake charge and increased air flow. Do not know how much HP increase I got but with using 15% more fuel had to be a pretty good increases with only changing the intercooler.

Find tomcat here on the forum or his company R Tech. Hopefully he's still in business, he's got all the intercooler stuff figured out.

I'm getting quotes on finned cupronickel tubing. It's a straightforward job of cutting open the Procharger coolers and fabbing up a CuNi zigzag cooler circuit in them. The finned tubing is expensive, and the box to tube seal is tricky but otherwise no magic.

Frozen Boost type 22. Done.
