Just bought an S for the track

[Jake Raby]

yeah, the box uses the coolant to cool the oil, so keeping engine temps down will keep oil temps down.

And thats barley marginal on the street and isn't anywhere close to efficient on the track. Most engines die on the track from a loss of film strength as a result of thermal break down and viscosity loss. I was able to carry out a post-mortem on over 2 dozen of these this year alone and all of them had the same story and the same ending.

I am going to talk to HRG about adding an external oil cooler to my BSR - its hot as hell out here in the summer and early fall!
