It's running around 540bhp for this year, a little up on last year, but the main differences are in the rev band. It's running the same short stroke bottom end as I use in my own car which means 9000rpm upper limit. As it comes on boost at 3800rpm it gives a HUGE power band which is essential for hill climbing and sprints where the car normally competes.

Mike, we had to change to the K&N due to technical issues with the ITG. Normally I have the ITG filters made with an internal plastic mesh to keep the foam cylinder rigid, however due to lack of room this was left out of the foam which promptly resulted in the filter collapsing on boost! Hence for now we're running the K&N until we can find a better solution.

Chip, I have no clear photos inside the rear arches, but in essence we trimmed the outer skin to the inside radius of the extended arch and then extended the inner arch to meet with the trimmed outer skin. The arches are aluminium and then rivoted onto the trimmed arch. This gives room for 10 inch wheels and up to 260mm wide tyres. Incedentally we had these new alloy arches made 1 inch wider than normal Group 4 lotus arches to give us some extra room.

Jim, glad to hear you're doing fine, but you must be getting bored of your Bavarian tourer!
