• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

My stock transmission finally broke, and I didn't even get a 10 second slip

First pass - All Motor. 3.0" pulley, C16, ~19* timing. The car went 12.9 at 104mph with a 1.8 60ft. Best ET it's ever done on the motor, and probably the worst trap speed. You can definitely tell the motor is getting worse for making power. It's all hole shot.

Next was spraying a 125 shot. The car cut a 1.7 60ft and went 12.3 at around 110mph. Got a large amount of knock, as I think there may have still been some 87 octane in the line.

Next run, I pulled timing back. Also on a 125 shot, it cut a 1.7 60ft and went 11.8 at 114mph. The car felt great on this pass. Trap speed is still 2mph less than it was in Tulsa a year ago.

Last run, I went for a 175 shot. Spun hard out of the hole, gripped, and then snapped what I'm assuming is the input shaft. I may have had too much air pressure in the tires, so it could have been my own fault.

Anyways, the car went 11.8 3 times over the past year, along with a WHOLE bunch of low 12 second passes. Plus a few nights of street racing during the summer. I can't really ask much more out a stock internal, 168K mile 4T65E. Although, if my 2nd stage would have actually worked like it was supposed to, I may have gotten pretty close to that 10 second timeslip.


Also, just want to say a HUGE thanks to Paul at PRJ Performance. This car would not be even close to as quick as it was without his help. Also, I'd like to thank Steve at ZZP for his help on my car.
 


I've been preparing for this day for quite a while, so I've got a lot of parts sitting on the shelf for a transmission that I can be a little more confident in.
