Hi guys, just found your great mod for us oldies who where around during the Group C days.

Thought I might just pop this bit of info here for you regarding the Group C A9X.

Homologated Gear Ratios. No race teams used the standard M21 gearbox, the stronger Borg Warner T10 was made as a 'dealer fitted' option for homologulation purposes.

Borg Warner T10 ratios:
2.43
1.61
1.23
1.00

After 1977:
2.64
1.61
1.23
1.00

Diff ratios:
2.60
2.78
3.08
3.36
3.55
3.90
4.44

Also, your 6500rpm rev limit is too low, Brock used 6800 during qualifying in 1979.

Should also be noted, the race version of the A9X used the already homologated L34 engine option from the LH L34, produced about 380hp. The road going version only used a standard L31 5.0L.
