You need e85 proof fuel lines don’t you?

I bet that isn’t a cheap fill up? My Rangie was £128 last fill up with diesel and that was not the super wow stuff. I get 30 to the gallon on 4.4 v8 twin turbo.

at the moment the clutch is fitted, recalculated the new position of the hydraulic center clutch bearing and made a strong frame so that I could already feel the pedal, and see what travel the clutch bearing makes before the plates are 'free'
With this there is no need to fit the gearbox which makes it alot easier to make adjustments

The nose piece from the gearbox also has some adjustments for the new position of the clutch bearing

Gearbox out

Old clutch/flywheel

Some adjustments on the milling machine for the gearbox nose piece

New clutch fitted

I mapped it on the 102 but kept it safe as high inlet and we was at the power he was happy with. Probably another 50hp in that’s package.

No I don't have any trouble with jumping out the gear. I also have the Oppliger short shift cradle fitted.
Have 2 Oppliger short ratio boxes and both of them still doing fine
