I dont think he is running many mods to the oil system at all especially considering he is running track spec tyres, not street tyres. Did you go to page 4 of the thread, here is what he says:

"I have the motorsport AOS, original Mantis deep sump, and 3rd radiator. 3 1/2 years and lots of tracks days in the top run group and no issues yet. I don't log the oil pressure any more since I eliminated the pressure dips with these mods and Mobil 5w50 oil. You still need a Motorsport AOS with the deep sump. I would recommend you add the 3rd radiator since it's relatively cheap and keeps both the coolant and oil temp down. IMHO the dual scavange pumps and accusump are not worth the cost. The engine oil cooler may be help if it's very hot and long races but i never saw oil temps over 220 if i remeber right even on 95 deg days."

Ok i was trying to contribute to the questions about the value of sumps, accumsump etc for trackdays. Personally for occasional track days i wouldnt worry but if it gives you sleepless nights then perhaps stick to the road!

Ive done trackdays in my 07 Cayman S inc nurburgring and have no mods at all and had no issues. you can search on planet 9 and guys there have done over 40 track days on the stock car with no issues. Obviously Im not pretending something couldnt happen but personally im not so worried on street tyres. Here is the thread I mentioned above which makes for interesting reading and is based on actual oil pressure readings on track. In conclusion, if i were a regular trackdayer I would buy a sump and i would use the one this guy is using:

I cannot see how this sump differs in any significant way from the Autofarm one.

I never said it did but at least you can see the guy has measurable benefits using the mantis

Fair comment but there's nothing to say that the Autofarm one wouldn't yeild similar results if tested and it's quite a bit cheaper.
