Guys, i'm running an AudiSRS Rolling Road day up at Dyno Demon on 28th March. We've currently got some interesting runners on the day: 4 K04'd S4's B5 RS4's - one with RS6 turbos 2 widebodied S4's.... one aiming for 450bhp, the other for 650+bhp!!!! If anyone is interested in running, it will be £35 a car and I'm taking payment up front. See here for more details: http://audisrs.com/ftopic3525-0-asc-0.php I ran one of these back in October at Dyno Demon and everyone agreed it was an excellent venue. Back on that date we ran a number of standard cars which came pretty much bang on their 'factory power', so the figures are reliable. It's a Dyno Dynamics machine they use and they give you two printouts showing BHP (crank and wheel), Torque, AFR anf Boost.
