Works MB 40Fi F3D pylon race motor IX For sale

Works MB 40Fi F3D pylon race motor IX

This is one of the motors used by Robert Van Den Bosch at the 2005 world championships in France.

This motor is a works development motor with some very strange ports although it has been run since being serviced, it is far from run in.

This is indeed one of the prototypes made in 2004 – 2005. Profi only makes production series, we make the proto’s in this case to play with port angles always ourselves.

They were made in investment casting and the material is Mahle 124. They have our own honing and chroming. Some are a bit more tapered than the production series.

There were appr. 14 different types made in his period. The IX means that the rear transfer ports ate angled 12 degrees, and the front ports , next to the boost port at 17 degrees. After the experiments ( blind, the guys did not know what the codes meant) we found that the flatter angles , 10 and 1 degrees mad ethe engine easier to use, the steeper angles ( we went up to 25 degrees, like Aprilia had these days) were fast but not so easy to use.

My advice: just run it. Take care that the length of the exhaust manifold is appr. 2 mm shorter than the production engines, so the pipe needs a correction of 2 mm.

Ballenstedt 2013

I have received the bad news today that the 2013 Ballenstedt Europa cup meeting has been cancelled due to a lack of entries. I guess it’s a sign of these financial times and a very busy world champ meeting, let’s hope that next year will bring everyone back out for some great racing race.

Until then we have the BMFA Nats and Tours to look forward to.
