    Heat Exchanger...???

    I forgot which thread it was under, but last year in the early stages of the first few conversions, didn't someone experiment with a Heat Exchanger to replace the 4TEC rideplate? What ever happened to it? Did it work/not work?

    Just wondering....

    I know Mark had first done that with his vigilante ski. I think it did work, but he got rid of it becasue it weighed a good 30-40 lbs. I am sure he will chime in soone enought though.

    Thats what I remember reading, weight was an issue.....But what if it wasn't? Just a thought? Would it migrate people to run modded plates on RXP's?

    I used a alfa lava (HVAC) heat exchanger on the RXPL convesion back in may 05.. but quickly replaced it with the open loop kit i designed..

    the heat exchanger worked good BUT it weight like 40lbs full and took up alot of space in the allready tight hull.. and there not exactly cheap.. i think i paid like 400. for the plate exchager i bought..

    openloop is simple, easy, and works... just my opinion...
    but if you still got your mind set on a closed loop system then look into HVAC type exchangers...

    I used a water/oil cooler. I forget the name, but it didn't matter since they stopped making them anyway.

    The biggest downfall, to me, is not so much the weight, but the fact that if the open loop water side of the cooler gets stopped up, then your engine will overheat. This is virtually impossible with Dan's open loop cooling system. It's simple and effective, and most importantly, works.

    What if you could have a heat exchanger that was small and compact, weighed around 10-15 pounds, mount ANYWHERE, and did a better job than the ride plate ever could?

    I'd sell it, and use open loop cooling.

    I don't have one, but considering the effectiveness of a ride plate mod that requires open loop, trying to keep closed-loop is a challenge...
