I am beginning to think that unless you test two or more cars on the same day, on the same dyno, in the same conditions and with the same operator that comparing the figures is completely useless!



Generally true, but its the different makes of dyno that cause the problems.

Simplest thing is to only ever use Dyno Dynamics dynos, because generally they all read the same and will do all year round. (obviously i'm going to say that hehe)

Yes, you would say that

It isn't really as simple as that though, some operators will inflate the figures by entering high IT figures etc. I bet if I went to another Dyno Dynamics dyno it would produce slightly different results.

So is there a group thing happening at Surrey Rolling Road then?
If so, how much would it cost? Can we bring non-HSV cars too?

No m8, just biglump on the dyno, I am just along to watch.

I am sure that Charlie could fit you in if you wanted to go though

Brakes sorted this morning by LSV (Big thanks to Doug and his team, top bloke and the coffee ain't too bad either) so will be at SRR at 1.30ish tomorrow as planned.

The first trips of many I'm sure....
