~400bhp CSLs?

[breeze]

I got my geo done at Thorney a little over a month ago and whilst I was there I had a brief conversation about engine tuning with John Thorne. We talked about what could be done to up the power of a a CSL without changing the displacement and it got me thinking.

How many CSLs are out there with the manifold to back box, Schrick, management etc all done and what are they making?

I'm sure between Evolve/Simpson/Thorney and the like we must have a few cars kicking out some decent numbers...
