Project Fredybender V2.1 : NA with an attitude for the track by fredybender

4 minute(s) of a 234 minute read

Opened up the dog box, as I wanted to change 5th & 6th gear (both too long IMO) because the tracks I visit, never have 240km/h stretches...

I had a friend help me out, and he had a couple of spares for that box.

As we opened up his boxes, he just remembered, that he had a 4.64 FD
I had a 4.16 FD in my box on the VWMS LSD

So, We ended up by leaving the 5th & 6th, and changing the FD to 4.64 Changed the ring gear, and output shaft

This coupled with my tire sizes, and 7000RPM shift point should yeild a 208Km/h top speed, which is just about right, for the longest straights, in the tracks I go to. I can stretch my redline to 7200, which will bring it up a few more km/h...

I will be going to Tremblant on the 11th of september, and I still have a bunch of stuff to do on the car; The keyway broke in my exhast cam, so I need to change the sprocket, and exhaust cam (already here, thanks to Collin at TT) I also need to change my seat belts, for some Schroth pull up type (also here) double check some wiring etc...

Just a few pics of the dog box
BTW the pink stuff is Red Line HD heavy gear oil (gears were not yet washed...)

First, a little video from end of june at Shannonville Motorsport Park (posted in another thread, but thought I would put it here too)

Didn't have time to edit...
From 0:40- 2:45 pits
2:45 - 4:25 Warm up
4:25 passing a 16V turbo Rabbit
7:35 Catching up to Z06
9:20 passing Z06

A lot of hours lately on the car:
I finally ended up by finishing putting back together the dog box, and changing the final drive ( The ring gear was so big, that I had to machine the inside of the housing to clear the OD of the gear Standard procedure recommended by quaife, when fitting a 4.64 or a 5.09 FD)

I also changed the exhaust cam and pulley (broken keyway) and timed the cams with a dial indicator as suggested by Schrick (intake valve on #1 cylinder has to be opened 0.098" at intake TDC) I am within 0.001" of that tolerance

I changed to Schroth clip on harnesses, and pull-up adjustement, with proper 3" shoulder belts.

Changed to Brembo slotted rotors and Carbo-Tech XP-20 race compound pads.

Lots of stuff done too much to enumerate in details...

On to pics
