I also produced a 2nd billet angle gear. Been a crazy busy spring / summer.

This unit went to a friend who lives in The Netherlands for testing. He has a highly built 850 AWD that he auto crosses in the dirt with. He has had continual issues with the factory cast angle gear case exploding upon launch when running the car locked 4WD. He setup the case himself with some help from me and he did a fantastic job!
 
He was able to recently race the car. The case and drivetrain are holding up great so far! Looking forward to more racing.
 
He is also making use of the forced pinon lubrication system which consists of an external oil pump. For his type of racing this likely isn't necessary (its meant more for cars that highway drive) but we figured it wouldn't hurt to run it.
 
Specs:
1. For use with 96-00 P80 with 96-99 gear set.
2. 7075-T6 aluminum
3. ARP 8740 case bolts
4. Grade 12.9 flange to transmission studs
5. Crush sleeve eliminator
6. All factory seals + Timken bearings
7. Factory gear set
8. Factory collar sleeve
 
Improvements:
1. Reduced seal bore diameter for tighter fit with metal seals
2. Improved M6 bolt recesses
 

Damn, sweet stuff.

Lots more changes happened this past month.

I installed a clutch slipper which will allow me to dial in the launches and basically just hit the 2 step and then side step the clutch pedal. 99+ P80 clutch master cylinder which has a position sensor that I will use to control flat foot shift.

I added a flex fuel sensor and at the same time thought it would be a good idea to redo the fuel lines in black and switch from rubber to PTFE.

I also converted everything over to black silicone and all vac lines to -3AN and -4AN.

Lastly I built a new intake to practice my aluminum welding and make the bay a bit more presentable. It also fixed a bunch of rubbing issues with the intake.

Lastly I threw it on the dyno to clean up the tune a bit. It made some serious power @ 30 psi. 818awhp/595awtq.
