Went to a local dyno day today. Mixed bag of cars, but who got the highest power of the day?
Spoke to Garry the dyno operator and he said the dyno reads very accurately and no more than 4bhp on a car like mine.
A chap had his stage 4 Focus RS on the dyno expecting 400bhp and made 367.7bhp and 373.7lbft!
Mine made more!
Dastek dyno
My result.....
