998 uses 89 teeth and 21mm wide, so wonders if pullies are smaller or the positon on 1098 is different ?

1098 uses same pulleys

So next step is to see if I can move position of tensioning roller over 2mm

Had 1mm turned off static and tension roller

No updates for a while as got a 14 day ban for speeding so cant get down to chris CJS Racing South West - Ducati cylinder heads tuning gas flow specialist

**fastphil** · 17 Sep 08, 11:44 PM

Latest update is Chris had some spare idle and tension pulleys so on his advice had a 1mm M/C'd off the diameters by
Bema Engineering Ltd

and kept the curved profile , which now enables standard 998 belts to be used.
Chris is now working on getting correct compression ratio

I have some F07 cases here that appear to have the same plug in them as the lambda take offs in the headers? Not sure if the threads the the same tho. Might be worth a try.

Yes the internals have been beefed up and straightened along with 5 new motors so that different types of testings can be done at well over the industry standard. Just waiting for the stainless steel top to make it look tidy around the control panel and bleed plunger.
