Fun reading the
I don't believe the stock cooler is garbage because it works great on the street for short bursts of spirited driving (I've had with and without) but of course it's not up to track duty. If you treat the streets like a track, it's not going to cut it there, either. But multiple 3rd gear pulls to redline on a hot summer day, the benefit of the stock cooler will be apparent in short order.
Is the oil warm-up benefit of the stock cooler worth retaining with an aftermarket track-capable oil cooler?
Would an ideal dual-duty setup retain the stock cooler, and use a removable block-off-plate for the oil to air cooler for track days?
