broke the car on the first of the month on a test and tune, finally tore into it today, here's the snapshot: stock 3.73's, (has the upgraded diff stock ,2011 brembo 3.73 package). I've beefed up the rear end with a che axle brace and the FRPP rearend girdle with bearing supports. I put the race tune in from john lund and was hoping to click off a low 10 second run that day. I was running MT ET drag 28x10S 15's doing 5k RPM launches. I got more than I thought I would out of the rear end. the only thing I hadn't upgraded was the diff and the transmission. everything else is beefed up in the drive line. 1pc ds, and a McLeod RXT clutch.
happened at the line on launch. first run I launched at 4500 rpm and she bogged a little, so the next/last run I launched at 5000 rpm and side stepped the clutch and gave it gas at the same time. front end lifted and crunch, crunch, crunch, that's all she wrote.
I'd like to believe the diff cover kept the diff in the rear and prevented more damage from happening.
here's the results:
notice the weight reduction mod to the pinion gear:
spider gears and carrier:
other side of the carrier and spider gears:
the valley of the dead spider gears:
only good thing about this is the axles are still good.
