Reply to "ZF oil cooler"

OK- fine. I based my comment on the fact that Larry Stock has the first trophy for a Pantera with a 150.00 average at the Silver State. He says the ZF in his red car gets too hot to touch at the finish line but he has no problem driving the car home from events with no ZF cooler or even a gauge- which he says is a distraction. I only put a sensor in our ZF to see what heat really builds up back there- the engine oil temp gauge was already mounted.

Haven't verified but I don't remember Jr Wilson running a ZF cooler on The Monster back in the day. And that steel body Pantera ran well over over 200 at the SS several times with no ZF troubles (but plenty of tire problems!) There are other Nor-Cal big-block owners that get along fine with no ZF cooler- Darryl Johnson's 545 inch Pantera ran well at several recent Standing Mile events.

Vintage enduros like Pat Hals runs (without a cooler) in Europe are another thing entirely. If I was going to run a ZF cooler on a dedicated enduro roadracer and it was legal, I think I'd investigate the water-to-oil Laminova take-apart type and avoid air ducting problems. I have a Laminova in our engine oil system- the same curiosity & equally unneeded- and it takes out 15 degrees F from 10 qts of 30-wt. Dennis Quella uses a Laminova on his Pantera roadracer's engine, but not- I don't think- on its ZF. Al Bloomberg's record holding C/Sports Bonneville pushbutton didn't use one, either. Stuff that's not there can't malfunction....
