[s-cars] rear differential cooler

[Trevor Frank]

My buddy was running the 25hours our here and found that after 3 hours
the rear diff blew out, the motor was putting out about 2x what was
stock.  They put on a diff cooler and it lasted a bit longer, just one
data point.  I know summit has kits with electric pumps.  I have had
lot's of problems with my car but never the rear diff, I suspect that
with the rear torsen it might be a problem since I suspect ther is more
gears/more heat produced.  I would give the guy's at stasis a call or
Champion and ask them if they have ever run a rear diff cooler, it might
not be a problem with the 4wd cars since we have two differentials to
split the difference in torque gain?

Gabriel,

Are you talking about overweight dedicated track cars like the S6? I am
also
having my center torsen differential modified to send more torque to the

rear.

I know BMW track cars that routinely use coolers or larger casings to
cool 
their rear differentials.

I am just trying to get information from anyone who tracks their car
that 
might have made this modification. I didn't want to reinvent the wheel.

Regards,

Robert
