Right guy's, I have today been in touch with John at Janspeed to try and arrange a car club outing at Janspeed for a 'Dyno Day'. Further information can be found here http://www.janspeed.com/carclubs.php
Basically, they require a minimum of 10 cars and would be £30 for two runs on Rolling Road. Regarding payment, they have said easiest method would be for driver's to pay cash otherwise an alternative method would need to be required to collect payment i.e. deposits etc. Having never planned a club event before on forum, better judgement would need be discussed.
I have provisionally arranged this to take place on Saturday 08 October 2011 in the hope that this would attract more people to take part. Times would be from 9am to around 1pm (subject to total numbers)
