I have the large t-stat controlled oil coolers and will be running in the Great Lakes. Glad you brought up the spring oilers they seem to be more commonly used. I should’ve considered the piston oilers but a little late. Short blocks assembled!

Did you ever see what Rookie was experimenting with and using. Pretty cheap and effective to achieve desired pressures etc. Little more sanitary than small gate valves I was going to rig.

we run the 2 stage water pumps -20 to the bell housing then 2 -16 to the x over then 2 -16 from intake to headers we restrict it at the exhaust pipe so header has full flow to try to stop hot spots.

the spring oilers are definitely worth running IMO.

Interesting, have you spoke with any of them or just what you speculated?
If you have spoke with them, oil, water, or intake air temps getting too high? All or one?
What do you reckon the water temps were those days? As in the water your were boating in.

Seems a properly tuned, fueled, and charge air cooled setup shouldn't be "held back".

not sure of lake temp probably low 80s. Yes did ask a few, mostly the replies were didn't want to push it that hard. So nothing concrete. One did say temps were getting high.
I agree if you get your setup right you should be able to maintain. Maybe with the merc. boats temps were close to putting them into safe mode? Not sure couldn't get a clear answer.

I do know a 700 with the stage 4 has heat problems. It was a very hot humid day that day also.
I remember reading that the 700sci heat exchanger maxes in the 950 range. If that was Dyno conditions, it’s probably lower in a boat on a hot day.

Im running 2 stage pumps also -20 from the transom feeding the pump, -16 to to the x over, -12 to the inter-cooler and out, -12 off the T-stat housing to the headers, Im dry to the tip so I cant restrict there so I figured the cooler dump would be the easiest.
