Here's the scoop

1. 916 trans in the 908/1 and 2 starting in 1969

2. 910 trans in the 908/3 like the one Vic Elford ran on the 'Ring in 1970...

Notice in the 910 transaxle the R&P are in the rear of the car with the exhausts and inch or so below the inboard universal joints. Wow

Well, I was 1/3 right. Can't win 'em all. Well, actually you can, if you have a 908/3. Who's gonna beat you?

I need 'em when my girls bring home questionable boys. Vibration happens!

I'll bet they were trying to get rid of specific harmonics and that they wouldn't last long at that torque... or it was an experiment and they squished out quick! Hmm. I wonder if they'd get rid of the low-ROM vibs in my 993/914????? (IMG:style_emoticons/default/beerchug.gif)

Naw. the dual-mass clutch didn't last long did it?

But the 908/3 had much larger tires than it's predecessors. I'll bet they were trying to soften the R&P hammering fed back from the axles. Rubber technology was thin back then... (IMG:style_emoticons/default/smile.gif)

No idea, but I recall hearing that they could dogear changes trackside...so it must have been a custom unit.

Any idea what the bore and stroke were?

Um, dude, I can EASILY do gear changes on any 901 style in a 914 at track side. Just slide the stack out and get to work.

i can only think that it was an attemt to reduce the shock of down shifts on the ring gear which can cause chipping of the gear teeth on the ring and pinion. i see it on off road rigs from the effects of bouncing the tire and shocking the ring gear against the pinion.

yea you're right.... with the wimpy assed euro torque [less than 250ft lbs] those flexy rubbers should be ok.

good ol 'merican torque would send those into a nice oscillating death wobble!

really what use would those be? if those are stiff enough to with stand the torque, what benifit are they?

They worked pretty damn good on a 1200 HP 917 (Schrapnel-Knobben turned all the way up).
