Dyno at the Ace Cafe Pictures
There was a good turn out at the Ace Cafe. Most of the VFRs got there before the HD crowd and corralled in one corner of the car park near the Dynojet mobile dynamometer.
Thankfully, the ancient William in attendance seemed completely un-perturbed by the loud exhausts!
With some trepidation, I allowed my P&J to be taken into the the machine. Gulp!
Front wheel clamped securely and the engine up to normal running temperature the test was begun.
Thankfully there were no problems and the power and fueling printout was produced. This showed 108BHP which is about a 10% power increase over the published figures for a stock bike. A very nice set curves were produced. Gone are the bumps and troughs that are common in a stock setup and the power curve hardly dips at all before hitting the rev limiter. The technician was well impressed and asked for the name of the firm who set it up for me. I told him that it was a PDQ map made for an identical bike and setup.
Also (as one might expect) there is no dip or step in the curve at 7krpm as is present with the V-Tech. The V-Techs were producing around 105BHP in a stock setup. Most of the non-V-Tech bikes had K&N filters fitted and aftermarket exhaust systems and were averaging 106BHP. One owner of a ZZR1100 was upset that his beast only produced 107BHP on a very bumpy curve. :-( Loads of torque though!
It was good to see borne out what I had found empirically. The PowerCommander is certainly a worth while addition as is the K&N filter and a good aftermarket exhaust system. You may argue that 10% more power is not necessary on a VFR, and I'd agree. It's all about how that power is produced and how rideable the bike is as a result of your efforts.
Safe and sound after the trauma. Poor baby!
