CWC's 9th rolling road day was held at the ever popular JDM Dyno at Kirkbride Airfield near Carlisle. 11 cars ran in total, and despite the snowy conditions plenty of others turned up to see what was on the rollers. As always there was a good mix of cars, but this time no rear wheel drives were brave enough to risk the wintry conditions and turn up for a run.

   In the cold conditions (-6 degrees at one point!) most engines ran well with the very dense air. Most people were happy with their power runs and a few were pleasantly surprised. A couple did go home wondering where some of their horses had wandered off to, but as ever Jonathan at JDM provided a few pointers that should help to tempt them back.

    The power runs shown below are flywheel horsepower, a 20% factor has been added to the wheel horsepower figures measured by the dyno to compensate for transmission losses. The actual transmission losses will vary by a few percent from car to car, but given that standard cars usually show standard power on the dyno, it's a pretty good approximation.
