Hi Mike,
Glad to have you back. Yes, I'm running a custom Fluidyne oil/water exchanger, but it augments the oil/air exchanger, not replaced it. If it was 25% larger, it might handle all of the heat load of the oil, but I haven't tested that theory yet. I'm sure you realize that the water radiator has to be large enough to handle the extra btu's, mine apparently was. If you want more detail, let me know and I'll send you pictures.

Well, it's not as beautiful as it once was. Had to add some ugly bumps for exhaust clearance. Finally threw in the towel on a clean oil cooler install and added a second scoop and stock RX7 cooler below the rad inlet.

Can I attach pictures here?

At the moment it appears during full power ground runs that I have excess cooling capacity, both oil and water. Never been over 180 on either. Which brings me to thinking (again) about oil/water heat exchangers. Has anyone successfully implemented one? If so what are you using? I may eventually be able to get rid of that second scoop.

Mike

I was on this list years ago when it first started up. Job change and other issues slowed progress on my project and I unsubscribed.

Hey, Mike's Back :-)

Good to hear from you again. Can't wait until all the new folks see that beautiful cowl :-)

Cheers,
