Well...Pat finally broke his T-case. After over 600 passes pushing almost 800hp it finally broke. Certainly is a testament as to how tough the stock T-case is though.


Quote and log from Pat:

I "cleaned up" certain data out of this, but is the "exploding Tcase" datalog.

It blew up at 22:36, watch the speed jump as the tires spin. 4650 RPM shifting.

Launched at 3200 RPM, 30 PSIG boost:

That sucks, atleast they got a chance to show that guy with the LMM up a couple of weeks ago.

 

Yessir

 

He had a huge jump in mph when his t-case went, and then when his wheel spin stopped his speed droped 10mph

crazy stuff. good thing it was just the t-case.Ive been readin up on that on pats site

too bad the LB7 is still better
