Dyno Dynamics rollers in the south?
Anyone recomend anyone who is likely to have a short notice slot available for doing a few power runs and a couple of mapping tweaks on a car next friday?
(we'll do the tweaks, just need the rollers and operator not any mapping services)
Further south and more central the better as the car is based in portsmouth.
We've tried JKM already.

Will ask Rob if he is allowed to stay over at my place, as we're heading off to woodbridge the next day anyway so that would be a good place to go if he was able to stay over, but bit of a pain if he has to go up and back in the day to be there to babysit etc.

Bet you see 180mph if charge temps are ok. I got a pretty good look at the cooler at the weekend
Looks manly enough

We've not had charge temps over 20 degrees yet when on the move, so that shoudl be ok hopefully.
Dont think 180 is realistic though with around 400bhp, Yum was a LOT more than that when he did his 178mph
Im seeing Rod on wednesday probably, so he'll be able to give me chapter and verse on what sort of power yields what sort of speeds so we can make a final tyre choice to set the gearing.
Currently we're planning on gearing it for 175mph at 7000rpm, which is a bit higher speed than we expect to get to but that is geared past peak power anyway I suspect.

Hi Chip
Just checked the drag figures on the web with 400horses you are looking at 177.2mph (8% less drag than a Sapphire), if you are geared correctly. Can I suggest 174/175 at peak Power because experience says it will pull past that once it gets going. You are 20 horses or so short of 180.
