I have a new BMW M3 (S65 V8 - TWS factory fill) with an intercooled supercharger system that increases power to 650hp. Durning extended hard use or track lapping the oil temps run 10C to 20C higher vs the stock engine oil temps.
According to other BITOG members the TWS is an amazing oil but it tends to shear to +/- a 50WT (~17cst @ 100C) in short order. My idea was to mix the TWS approx 50/50 with Motul 300V 20W60 to keep the viscosity up for high temp operation. The bearing loads must be very high with forced induction and over 200hp more than the stock engine produces so I want to give it some added protection for high RPM use when the oil temps are above 100C.
Thoughts?
