25 years ago when I put a 3.0 SC engine in my 914, I understood the need for additional oil cooling, but I didn’t want to cut up my frunk, or run 26 feet of oil lines. My car was a street hot rod, and really didn’t plan on doing track events, so I didn’t need the maximum possible oil cooling.
My solution back then was to put a 25 row Mocal cooler with a fan sandwiched on it in front of the right rear wheel, on the opposite side of the car from the oil tank. This worked out well, and neither I or the current owner has seen oil temps out of range. I have another street hod rod in the works and since the right rear quarter panel was removed for rust repair, I decided to revisit this alternate oil cooler location. After measuring, mocking up, and some head scratching I figured a 34 row 234 matrix Mocal cooler would fit. Here’s what I’ve come up with. To test fit a Spal puller fan, I taped it to the cooler. Two holes drilled for the front bracket and one weld nut for the rear bracket. 3 M8 cap screws are more than enough to secure the cooler |

Curious what kind of air flow you will get in the fender? I have seen people put a duct in the rocker to force air into that area.

Curious what kind of air flow you will get in the fender? I have seen people put a duct in the rocker to force air into that area. It can't be any worse than the 911 front fender location. There's only a 1 inch x 6 inch opening under the bumper and the headlight bucket is so close to the top of the cooler that a fan will not fit in front of the top of the cooler. The one thing it does have going for it is that the entering cool air is separated from the exiting hot air with the shroud and foam gasket. Not sure in the 914 rear wheel well how the hot air exiting the cooler is kept from being sucked back in as cool air. Attached thumbnail(s) |
