Don't forget about Ed Klepeis of Tech Welding.  He should be able to make one from an existing heat exchanger.  Basically, the Fluidyne oil/water exchanger is just a heat exchanger wrapped in a metal canister.

Al,

 

I have the dual core E54-329 sitting between two 400ci radiators. No idea how it will work yet.

Who makes the water/oil cooler system I've heard about, and does it work???

Thanks again.

 

I recently installed a MoCal Laminova 43-330 oil/water heat exchanger as a backup to my oil/air cooler.  It works as advertised; and will handle roughly ¼ - 1/3 of the heat load for the 20B. That was all I needed to keep my oil temps below max during climb on a hot day.

 

Setrab still makes a couple of units of lower capacity TOC-150 and TOC-200, but the larger TOC-300 is currently out of production.

 

Fluidyne no longer makes oil/water units, but some still show up now and then on e-bay.

 

C&R racing will make a higher capacity unit for you – at a price.

 

Al
