Dyno Time - Group C RS2000
Posted: Fri Apr 06, 2007 3:05 pmHere are a couple of videos of our dyno session last Sunday with the Group C RS2000. Basically this was a fresh engine, so we took about 45 mins to run it in before we started on the power runs. So with everything checked and set, we started with a couple of runs up to 7000rpm to ensure all was well and the air/fuel ratios were sitting correctly.
That all looked OK so it was onto another set of runs taking it up to around 8000rpm. The first two pulls were with a "slow" rev rise, while the last two are more full throttle runs.
After all that, max power arrives at about 7500rpm with a flat torque curve from about 3500 - 7000ish rpm. Very very happy with the result. Can't wait to get it out on the track.
Big thanks go to Danny for building the thing and making time on a Sunday to do the dyno work, Gary the other Dyno junkie, and Mark D without whose alternator the job would have been a lot harder than it was.
And Roger for hosting the vids - Thanks!
Oh, and make sure you have the sound turned up LOUD
