Well, it was bound to happen.
I took the Viper to the track Saturday with the new setup. I wanted to see if the car would run a 10 second pass on the BFG drag radials and pump gas.
My first pass right out of the box was a 11.48 with a 1.85 short time. Knowing that they were going to piss and moan about running faster than an 11.50 without a cage and jacket, I decided to just make 1/8 mile passes and work on launching the car.
After about 8 burnouts and 8 1/8 mile passes, I was feeling more comfortable with launching the car. With 19 psi in the tires and leaving at 3000 rpms, I pulled a 1.57 60' on the drag radials, but aborted the run anyway. The car still bogged a tad out of the whole. I figured I'd leave a little harder next time.
The next pass, I left the tire pressure at 19 psi, but tried to leave at 3500. It spun a little, but I went ahead and stayed in it. The car went 11.09 @ 127 with a 1.70 60'. Ok, so 3500 rpms is too high for 19 psi.
Next pass, I took the tire pressure down to 17 psi and tried to leave at around 3200 rpms, figuring that should be somewhere in the middle of bogging and spinning. I pulled a 1.62 60' and the car went 11.02 @ 127. With less tire pressure, the tires bit harder and the car bogged. Ok, so with less tire pressure, 3200 rpms isn't high enough. I figured with 17 psi in the tires, I should be able to bump it back up to 3500 rpms.
For the final pass, I made sure to do a full on John Force burnout and get the drag radials good and hot. Staged the car, took the rpms up to about 3500-3600 and let it rip. The car hooked HARD and then SNAP! Busted the driver's side halfshaft, u-joint and end caps. That should have been one hell of a pass. Oh well. [******] happens.
The car definitely has a 10 second pass in it the way it sits on 92 octane and radials. I just didn't get to prove it this weekend.
I guess if you're not breaking something, you're either not making enough power or not trying hard enough.
So, who has some stock halfshafts/u-joints laying around?
