Smashed Pinion Gear - R200 Diff

Broke the rear differential pinion gear at Oran Park recently and pulled it apart and replaced with a 4.08 ration crown and pinion


This is the new crown wheel




Old 3.69


Removing the sump plug you can see the large chunk picked up by the magnet



Dropping out the oil

Removing the diff cover, impact wrench makes light work of it.




Cover off and nice big chunk of metal at the bottom

Firewall Alternator Power Connector

This afternoon I was pretty happy with myself. After 2 weeks of doing nothing much aside from things to do with other then car i managed to get into the shed and watch the Wakefield 300 and then V8s whilst fiddling with the car. I managed to get the Alternator firewall connector drilled and pretty much fitted as well as changing the rear of the power panel. I had to do this as after deciding to go with the Tyco isolation switch I needed to change the wiring around a bit.

Trackday Troubles - Blown Intercooler Hose

-
Image
I was lucky enough to attend the Macquarie Racing trackday at Wakefield park, was a fantastic day. I had planned to shake down the car after the clutch install and with the previous overheating issues that I had experienced. The first session the temps were around 24deg with little to no wind, the car performed well with temps very stable after 8 laps at around 1:04 second mark. It was just me and two other cars out of the track, I came back in to check on things and the tyre pressures. The second session I wanted to continue to check the car and if all was OK I would duck out at lunch time and put on the 3 spare tyres I have had sitting around for about 5years, not the best to set times on but with the rears now without tread I needed to change them over. Unfortunately about the 3 rd lap in the intercooler hose blew, trying all of the shops in Goulburn I was not able to get a replacement 2in to 3in 90deg elbow silicone joiner.

When I got home and realized I could see that the car had moved back about 30 cm and onto where I had secured the splitter using the remaining strapping from the now loose tie down. Had I hit the brakes hard there was nothing stopping it from moving forward. I have been using the following method for some time which is, two tie downs off reinforced front tie down points on the car to custom eye bolts on the draw bar. One one strap across and through the rear diff cradle.  This method  has worked well up until now, with 11h trips to Phillip Island and having minimal issues, I think a mix of tiredness and not tightening the straps correctly have caused the issue. Time for a rethink. I have been looking online at a number of different options and methods and came across one that uses the existing 50mm wide tie downs and a short stra...
