UrS4 2.2T Avant project

[Thuppu]

Recieved a nice little package from Finjector today. Two flowmatched EV14 injector kits. 2300cc for the UrS4 and 580cc for the 80 B4. + some other small things, water/oil temp sensor, connectors and spare viton O-rings. Got a really great "sponsor" offer from them.

Main lever has push/pull hooks which rotate the shaft with 2 discs that act as cams to position the 2 rocker arms that will cable or rod actuate the selector?

Yes, just like that. This version has two different hook arm, one for push and another for pull.

Just finished design of a more simpple arm that has both push and pull hooks, so the total height of the box can easily be 10-20mm lower. Also the final design of the box will be smaller and slimmer. But this proto is good to test the disc and actuator movement, so the shifts work on the trans properly.

Interesting, do you have any pictures of the mechanism?

Yes please!!!!

[Thuppu]

Nick, yes your right. It can be a problem with the synchro gears. For dog gear it's just the better the faster the change is. But as I still will have synchros in 3-6 there can be some difficulties with too fast shifts.

i like your shifter thomas but i think you have no longer a good feeling in the gearshifter when you are shifthing the gears and there is something wrong

[Thuppu]

Interesting, do you have any pictures of the mechanism?

No, not yet. I propably have to modify the switch plates some, to get the gear change work properly. Have to get the cable links first...

Nice ! Are you gonna build neutral gear release lever? I mean lever that you pull and push shiftstick to shift neutral no matter what gear is in. It could be useful but not necessary

Propably not, it would make it more complex and I like to keep it simpple. Should work like an motorbike gerabox. Only thing could be a lock for the reverse gear, so you don't try to grind it on on the move.

Recieved some more parts for the transmission today...

[Thuppu]

Supercharged down low torque, horse head size turbo, and now aided gearing... I guess bad 1/4 mile times is then caused by the driver, haha.

Yes, it's 1-2 gears with custom ratios. 1st is 2.80 and 2nd 1.82. Dog engagement should give slight faster shift than syncro. Also shaft is thicker with chevy spline.

Slightly? If you get it perfect I turns into a f***** rocket
