[Fot] Gt6 differential failure

[Keith Files]

Hi Jason,

It was me discussing diff coolers.

I have the photographs of my installation now and will be sending them to the guys who wanted to see them. I will copy you too if you wish.

Best regards,

Keith

>> thanks, Jason - yes, I was banging through the gears, and there's now a steep 150' +/- DROP at this track, downhill turn, where I was in second gear at 7,000 RPM, first accelerating, then letting it slow me down as I approached the sharp right to the uphill climb.  I'm sure that did not do the diff any good.
