Underperformed on the dyno
I had my 2007 s4rs with full Termi exhaust (new ecu filter header) on a dyno this weekend and it reported 121 rwhp. I was expecting something in the high 120s but definitely not as low as 121.
This dyno test was a freebie put on by a local dealership so I didn't get a print out or to talk to the guy doing the testing. Other people had their bikes dyno tested as well and experiences similar results/feelings to mine.
Any ideas? Does this number seem on par?
BTW- after the dyno I noticed that there some black residue on the slip ons that I've never seen before. I do remember some black smoke coming out during the dyno for a second, but I saw this on about 10 of the other 25 bikes tested. Any thoughts or ideas are very much appreciated,Dyno's are not zero'd out across the board, each one is a bit different. It's a tool for measuring losses and gains, nothing more.
Pretty obvious by what you said that the dyno might read a tad lower than others. Nothing to worry about whatsoever.,,,
