Removing thermostat - pro's and con's

for track i would just get a baffled sump & oil cooler.
Low opening thermostat, not sure how much benefit it would make for track as your therostat will be opened pretty quickly anyway

I think it's likely to be a bad idea on an EFI engine, unless you knew for sure that the engine was running at a high enough temp to be outside of the cold running open loop map.

If you run cold (relatively), and as a result run rich, then aprt from the loss of performance likely the excess fuel gets deposited as a liquid on the bores and washes off the lubricating oil film causing accelerated wear (bores, rings, pistons), as well as getting into the oil and degrading it much more quickly.

generally only boosted applications i'd recommend one
