Do you have any specs you can share?

Sure:
Oettinger 74mm chro-mo crank with 55mm (1700) T4 rod size
Custom cast 98mm alu cylinders with special/experimental coating (should be even better then nikasil)
JE turbo spec pistons
Pauter cam, lots of duration and lift
Pauter light-weight-series rods
Pauter alu ratio rockers 1:1,48
TP dry-sump oil pump
TP 52gram T1 lifters
TP alu double tapered pushrods
TP billet cylinder heads 48x41 with Ti valves, Ti retainers and Ti valve keepers
CB650 valve springs
Compression ratio around 9:1 expected, but still to be determined/measured.
48mm throttle bodies from VWSpeedshop England
Ok-products manifolds
Horizontal cooling system from Orratech.de



Thats about it for now. Lots of work to be done still. Turbo system to be determined, but I have some ideas

Hello airspeed are you happy of the cooling system from orratech ? I m looking for one for my type 4. Orratech or riecther.

[Airspeed]

Orratech system not installed yet on my engine, so I have no personal experience...

Not sure what you mean exactly, but I do have an extra set of 4 Ti inlet valves still unmachined (but can be shortenend) and 8 unmachined Ti valves (in the box) but which you can't shorten as I understood it.

Is this what you mean?

[white lady]

Germandrag research 4 inlet Valves Ti and he wants to know if you have another set for him.

[germandrag]

Yes exactly, 48 or 50 mm
Merci white lady !
