Here we go guys R36 1/4 mile

Or is that the difference between a run on a hub dyno and a roller dyno?

Hub Dyno will always read higher - dunno if it would be as much as 40kW higher though...

It's not quite as simple as saying a hub dyno will always read more. There are pros and cons to both, but at the end of the day a properly calibrated hub dyno is also telling you KW at the wheels - the size of which is one of the parameters entered.

The reason I got mine done was for a benchmark and base line, not to compare with roller dynos though - and because going back later it is far more likely that they can reproduce the same result with less variables.

This is a useful page that discusses why hub dynos tend to read slightly higher. http://home.earthlink.net/~spchurch/id12.html As Pana says though, it shouldn't be 30KW higher...

yeah - ignore the "always" in my post then

Hey Guys. Went back today and pulled a 13.38s 1/4 mile - so the remap has clearly sped things up a bit.

Not a fair test though, I think there was a little more improvement to be had. My pre-remap 13.66 was done on Shell V-Power 99RON fuel - but this time it wasn't as there wasn't any available locally.

That and I have 12'500 miles of crap in the air-filter which isn't going to help things either!

Still, pretty happy

No lack of grip either. I suspect I could run with slightly higher than stock pressures to lower the rolling resistance without impacting on off-the-line grip.

Still 13.38 is nothing to sneeze at for a nearly stock car!

What MPH did you run with that time?

:-ppppppppp rub it in Rob.

Well done, that's a good time.

Hey Guys.

Have uploaded a video of this weekends run: http://www.youtube.com/watch?v=0w3Fz3AfRVs

I intend to go back soon with a Pipercross Panel filter and V-Power 99 in the tank. Maybe 2-3 psi more in the tyres too, as there where no traction issues. Also tempting is a DSG remap to up the launch control rpm once its available without posting the controller to HGP in Germany.

You never know, with a tail wind I might get a 12.99 one day - but I doubt it..!!
