Went down to Hidden Valley for a Motorkhana on Sunday. Got some video, and I can feel another compilation coming on. More on that when I get it done.

One of the V8 Commodores was testing in the afternoon on the track proper. I managed to work in with him (thanks Rick!) and do a pair of 5 lap 'Tests'. There was no timing, and my GPS was flat so we had to go back to the stopwatch. I ran a couple of hard laps in the 1:25 zone. The radiator ran a nice constant 95 deg and dropped to 90 rapidly after getting off the pace. The oil temp still ran too hot between 110-120 deg and didn't move much on the cool down lap.

I am stumped. The only way forward from here is either a larger cooler core (I have a 10 row) or have another look at the ducting. I am wondering if the air is not getting out the back of the core for some reason. Maybe I'll try running some ducting from the cooler out to the side of the wheel arch with the aim of using the low pressure on the side of the car to 'suck' air through the cooler.

The other option is a small fan to draw air through. Or some sort of water spray...

I'll spend some brain cells and see if I can knock something up before going to a larger cooler.
