Is anyone running a closed loop cooling system on a larger HP engine? I've been thinking about doing my do diligence and installing a set; it looks like kits from reputable sources are mostly hovering around the 500-650hp range... OR, I welcome a comforting conversation about how great flushing/saltaway works on an all aluminum top end w/out brass inserts lol...

Give Marc at BAM a call. He did a lot of work with HP Closed Cooling on his stuff back in the day.

Thanks, will do Andrew. I got your PM and email. Very much appreciated.

Even though I'm a salt water cheerleader who doesn't believe that it instantly turns metal into pixie dust, I was shocked at the amount of corrosion that shows up in the thermostat housing in just a few hours of use (and I don't have stats and flush with salt away after every run and the boat stays on the lift at all times).

I hear that and its exactly why I'm paranoyed... I'd like to think it doesnt waist into nothingness in hours but some of the "stories" out there are a little troubling...

If you can get a hold of Dustin w/Whipple he may be able to help as well. I know their stage 3 and up 600sci and 700sci upgrades are near or above 1000hp and I think that's where they started running into issues with the Merc closed cooling.
