Along with a bigger engine.looks like someone mounted a cooler near the rear grill with a fan
Possibly off one of the 4-cyl FWD Chrysler products that used VW engines? I'm just guessing because that unit is the one most commonly used by VW on engines from the same era as the Chryslers.it is a chrysler cooler
Pete, it would certainly work. But I have to say that on a street driven car, with lots of start-up/shut-down cycles, stop/go traffic conditions, climate fluctuations, etc, the delay in getting the oil to circulate through the longish lines (to the front of the car) might be more of an issue than on a racer where it is allowed plenty of warm-up and driven at constant high RPM's for occasional durations. Perhaps if some sort of anti-drainback valve was added to keep the cooler and lines full of oil at all times, then it would avoid the delay in building oil pressure. Or even one of the oil thermostat units mounted near the block, so the oil isn't sent through the path to the cooler until after engine warm-up (and therefore after full oil pressure has been achieved in the engine). Maybe I'm just too conservative, but I hate seeing the lag in oil pressure with normal engine start-up, let alone any system that might delay it longer. Again, for a street car anyway. Otherwise the front mounted cooler location is ideal in terms of air flow and heat exchange.I ran a front cooler on my X1/9 race car.

I don't disagree with anything you stated at all. However keep in mind that "start up" is where something like 90% of engine wear happens. And for a street car start ups happen a LOT more frequently than for a race car. I have similar concerns with the engine's water cooling system - those long lines for the pump to overcome.That is only a concern at startup.
Absolutely! I've often considered some sort of "automatic" arrangement for something like the Accusump, suitable for regular street use. It isn't difficult to plumb, but I'm not certain how it would work in real world applications. Sure would be great though.It's a thing of beauty to see 40 psi of oil pressure before you hit the start button.

I was thinking in terms of when it's used on a street car. I'm not sure how well they maintain the holding pressure over time, or what other concerns there might be compared to a race car. Very different scenario to just jump in and crank a street car several times every day, without going over all the systems and verifying things before starting like I do on race engines. Plus I was thinking you might have the manual valve type - that's what I had on my race car. The electric solenoid type is more what I meant as automatic, like you describe. But the other concerns are the things that might keep me from doing it for street use.Not sure what you mean
I’ve run 5 seasons on my race car with those mounts on my radiator fan with zero problems. Admittedly the fan only runs in the pits or waiting on the grid. So curious as to why?Whatever you do, do NOT use these attachments to mount any electric fan on any cooler/radiator:

I suppose it is mostly personal preference, but to me the idea of putting a object through the soft aluminum fins is asking for failure eventually. Especially when they support a fair amount of weight that's pulling against the core. Furthermore if the fan housing is resting directly against the core as a result of this type mounting, there may not be enough of a air gap to allow optimal flow across the rad. Look up the recommended specs for how far a fan should be away from the rad; it's actually different for a cooling radiator vs a AC condenser, etc.So curious as to why?
