Glen?
Who speaks my name?

I'm no master of anything...especially ABFs!
I also have no idea on putting taller gearing on an ABF as I thought the standard 'box was awful enough (tall geared), so I was only interested in shortening the gearing.
I think my current VW Motorsport 6 speed semi-straight cut 'box does 18.5MPH/1000RPM in 6th, using a 4.2FD. As for taller ratiod' ABF 'boxes...no idea. The way I'd do it is to fit a VR6 FD to the ABF ratios...but that involves a gearbox re-build.
