DDK - Die Deutschen Klassiker

Final few snaps from my visit, all ready and waiting for an engine.....fuel and oil systems all complete, trombone oil cooler not strictly period correct, correct oil coolers for a t/r or r are like hens teeth and stupid money....

Thanks Tim, your help in sourcing parts and trying to keep as much of the build aligned with how these cars were originally has been greatly appreciated

All thanks to Tim B

looking good

Hi Mark,
Like the blue car you built previously, this looks brilliant.

Hope you enjoy it soon.

Kind regards
Gitesh

Engine in progress a couple of challenges resulting in a new set of cams and minor modification to the pistons. Dummy build complete, piston to valve clearance checked. So final build we'll on its way.

Looks great Mark, that car is very close to my ideal spec! Any more details on the engine going in?

It's not been plain sailing the engine build, but hopeful it's nearly there.

Will post a full spec for the engine when it's finished. We think it should push out around 190bh, which for a a very light swb car will be more than enough

Starting to look pretty

Engine is now finished, the plan is to get it dyno'd and set up before we put it in the car. I have summarised the engine below for those of you who are interested. The plan was always to build an engine based on what may have been done back in period for those racing their cars on a weekend. I hope to do a few track days, but it will mainly be used for weekend blasts and road trips
