Mocal vs Tilton oils cooler pumps, One better than the other? Options

[pcar916]

I'm adding a cooler and pump to my transmission. These two pumps are similar in specification and both companies have been around a long time.

Tilton: http://www.summitracing.com/parts/TIL-40-524/

Mocal: http://www.racerpartswholesale.com/product...ial_Cooler_Pump

I know several of you run Jabsco Water Puppy pumps, but I see no advantage to it over the Mocal or Tilton.

Anyone out there with experience as to whether one is more reliable than the other?

Where is the cooler itself usually mounted?

Did I read correctly that one could use the fill and drain plugs tapped for cooler lines for in and out?

This sounds like a step in the right direction, as i could install everything, and then install the internal spray bar later when I have the tranny out.

Cooling the oil without actually spraying it directly onto the gears still sounds like it would make a difference.

The very early racing 915's (a la 3,0 RSR) used an oil pump in the tailcone and a cooler in the left side rear fender scoop. I seem to recall the 2,8 RSR's (which did not have vented fenders) using a cooler in the left front fender, like the trombone coolers fitted on the right side for engine oil.

Then the later 915's (915/67) used in the Euro 3,2 Carreras have a gear-type oil pump (like a VW T-I) in the side cover to route oil through a finned serpentine tube mounted in the airstream alongside the transmission. It's relatively light weight and efficient and works "well enough" to keep temps under control. AFAIK the G50 cars don't have or need this.

I have a 915/67 I'll be using in my RSR clone/homage 911.

Things to remember tho - in the 911, the transmission is well forward of the engine and the exhaust, so even though the airflow isn;t optimal, it is at least relatively cool. And unfortunately, there isn't room in the case for the pump _and_ a flipped R&P for midengine use. You could think about using this approach for an inverted box, but then you have to deal with plumbing the inlet to the pump, which is no longer in a convenient place at the bottom of the oil pool.
