We recieved some parts for the new engine.


New crank


Con rods in titanium


Pistons that are much lighter than stock pistons

The parts will be used to make a 3.4 l conversion.


Special made headers might give some addtional power increase.

Finally we have also have two sets of airboxes one CSL airbox and one custom made. We will try both to see which gives us most power.

Once this have been tested out it might be available as a tuning package from Kelleners Sport.

Cheers,
/Johan

johan,

you are really going all out on this arent you?;)

Who company manufactured the rods and pistons? Also what CR are you going to run on those pistons? In addition the pistons seem to be coated, and chance you could tell me what coating might be on them?

As for the airboxes, who did the custom box as I know that the CSL and Delage airboxes are about equal in efficiency.

Very nice stuff!

This year we take one step further. :)

Pistons were special made for BMW Motorsport by Mahle. CR will be 12.5:1. Don't know what coating or material there made of but they're 309 g inc. bolt. AS for con rods, I don't remember but will check with Ralf Kelleners as soon as he is back from testing at Daytona.

The airbox is made by a German company, can't tell you the name right now.

Thanks! :)

Cheers,
/Johan

luvelyluvely!

Dunno if I'm the only one, but the internals of a high peformance engine are pieces of art to me. Screw paintings or statues, I can spend hours looking at this kind of stuff, and then enjoy them as they perform there art togheter as a finished engine.

If you could keep us updated with pics of the engine build, I'd be very gratefull!

Good luck with the build-up. Can't wait to see the car back in action.

Regards,

Gerrit
