Again am I too young to know what movie this is?
5 to 10 pounds, depending on the speed you’re doing. Not to exceed 12-15.
Mr. MomAgain am I too young to know what movie this is?
Never seen it
its worth watch, pretty funny.
Or milkshake the oil.
more like 15, biggest thing is it will spike
I haven’t seen anything higher than 15 psi on our TCM 1200 at full tilt. Not totally sure where the gauge is reading this at though. But I figure the sea strainer can only handle so much as most have that lexan cap.
On our jet, our intercooler was not on the jet circuit, it was only pressure fed from a hull pickup so essentially only cooled at speed. I assume this was so the fuel didn’t puddle in the intake manifold at idle.
Haven't installed a water pressure gauge, yet, running out of dash space, but with the intercooler separate from the engine cooling water, running a -16 to the separate strainer, -12 to the intercooler and two -10 outs, I figure I gotta be OK?
Is your IC system still "pressure fed /via engine systems "? or "passive" (scoop)
Just a thought, are you asking about pressure in the intercooler circuit or the motor circuit?
That scoop can generate significant pressure and volume , may have to check pressure and regulate
My blower motors were on a separate system for the inter coolers with thru hull pickups. Teague said not to run them on the pump system because it can cause fuel to pool at idle . Ps. It was an I/O cat.
Good question, I was asking in general but should they be different?
Fuel to pool at idle? I wonder why..
It happens in the intercooler if it’s too cool . ( only at idle) A bit of heat at idle keeps the fuel suspended.
I’m changing the drive lower so no more water pickup. I planned to use the dual outlet Latham and plumb the intercooler to one outlet then the other side of the pump to the block and out to the oil cooler like it was set up originally. Currently I’m running a stock Mercury pump and see 10-12psi max. I’m not sure how much the Latham pump will make.
Interesting. So maybe plumb one side of the Latham to the oil cooler then through the intercooler then out the back? that way it’s pre heated a little?
I see, that makes sense. If that’s the case I might just ditch the dual outlet Latham and keep my mercury pump and just use two pickups. One for the motor and a second for the intercooler by itself.
Very nice
For the intercooler, if you have good hoses and fittings then don’t bother with a pressure regulator on it. On our TT BBC in our jet we ran as much water through it as we could from the hull pickup. The more water the better the cooling. Maybe it’s recommended to put a regulator on it these days (Water pick ups are better now) so you can if you want.
I wouldnt think so. My 500 with a whipple is pumped water through fuel cooler, oil cooler, p/s cooler then motor picked up through a thru hull. Intercooler is simple pressure fed through the pickup in the drive. Using a gen4 style hardin pump. Typical closed cooling systems will operate up to 15psi cooling system pressure. On my old big block I would 25psi at wot, never had any issues.
It is a carbureted setup
No fuel cooler then. I dont know if anyone really monitors water pressure through an intercooler circuit. In closed cooling systems, coolant caps are commonly 15psi and like I said before i ran up to 25 at wot. I think the weakest link would likely be the intake gasket between the head and intake manifold but a quality gasket installed correctly with proper fitting components should take 25psi. Adding a pressure relief valve can help regulate your water pressure but keep in mind the size of the fittings on the pressure relief. Depending on the volume of water you pick up vs the restriction on the outlet ( likely the holes in the tailpipe ) a pressure relief wont do a whole lot if it cant bleed off enough volume to reduce the overall water pressure. Really is something you'll have to monitor and make adjustments as necessary. You said you are changing the lower unit and cant use that as a pick up? What lower are you going to use?
Im swapping my sprtmastwr for an Imco Lower. I guess it’s not that I can’t use the Imco lowers water pickup. I can, it just seems like every Daytona I see with a similar setup uses a stand alone sea water pickup with sea strainer. I definitely want a sea strainer and a secondary fine sediment strainer to feed the intercooler. Bottom line I want the best possible setup.
Where’d you get that relief valve? Looks like it’s SS?
Came in the boat. Not sure. Asked Dave Connolly if he knew the origin and he wasn’t sure either
I like that, nice and clean
I hear ya. No strainer on my intercooler but I periodically back flush the intercooler, food for thought
Good josh will get you squared away
