Dyno time with the Caterham 420R - how much power does it make??

After living with the Caterham 420R for a year I decided it was time to see if I could get a few minor engine issues sorted out. It's always struggled to start from cold, and I've never been happy with the throttle response and some aspects of drivability. And of course, I was curious what power my standard engine would produce. So it was on the dyno at Northampton Motorsport for some expert fettling, with a bit of a surprising result.
