Here is an interview with David Holdforth, alias "Dyno Dave" of Sydney Dyno Pty Ltd:
Paul: Can you tell me roughly how many bikes you have dyno tuned, since starting Sydney Dyno in 1999?
Dave: It is difficult to give an exact number, however it would easily exceed 2,000. Many of our dyno charts are available for viewing on our web site, www.sydneydyno.com.au (links to Dyno Charts page, ed).
Paul: How is the current tuning business landscape?
Dave: We are flat out at the moment, but that is not to say that we don't welcome new customers. Our current pipeline has included a Suzuki GSXR 750 (2001 model), a 2008 Suzuki Bandit and a 2009 Yamaha R1, just to mention a few. It is interesting to see the comparisons of the same model bikes from different years, such as the R2 and the GSXR's. We already have the following immediate bookings for a 2009 BMW HP2, a Ducati 749R, a 2003 Suzuki GSX750, a Triumph based Thruxton, another Yamaha R1 (2008) and Ducati Desmosedici fitted with Carbon Rims.
Paul: That's a pretty exciting list of machinery. Are these for private clients?
Dave: We do a lot of work for Magazines, as well as for the racing fraternity. Private customers are also well represented, of course. Both the BMW HP2 and the Ducati Desmosedici are for magazine articles.
Paul: You mentioned carbon rims on the Ducati. Can you tell me a bit more about this?
Dave: We are doing extensive testing on carbon rims and the effect of their lighter weight on power delivery and responsiveness in handling. This has been a major project for AMCN magazine (Australian Motor Cycle News LINK), and Sydney Dyno is providing dyno charts for the next issue's article. We are also involved with a couple of Ducati owners who have been trialing these carbon rims on the road and track. It seems that not only do they contribute more immediate power delivery but greatly enhance the directional responsiveness of the bikes, especially at higher track speeds. This makes sense, as the unsprung weight is significantly reduced at the most critical position: at the rims, which also means lower gyroscopic resistance when fast lean changes are called for.
Paul: Sydney Dyno has a long association with Power Commanders. What is the latest news in this area?
Dave: My involvement with Power Commanders goes back to 1999, when I brought the first models back from the USA to NSW. Sydney Dyno was founded soon after, and was equipped with a special dual drum Dynojet 250i/168 dyno. This allows us to tune racing karts, as well as motorcycles. The latest products from Power Commander include the new Series V USB devices and the Quick Shifter. We also have the latest Tuning Link setup, to allow computerised tuning at all load and rpm settings. We can even develop a different fuel map for the front and rear cylinders in V-twins, as they run at different temperature.
Paul: Are racing karts a special interest for you?
Dave: I have been involved with kart racing as well as motorcycles, for many years. I hold 3 different track lap records (still current) and 5 State Championship Titles so I have a special fondess for karts. However, over the pasr 10 years I have concentrated on something for which I have always had an affinity, an involvement at levels with motorbikes. Having ridden since the age of 14 and fallen off more bikes and tinkered with more bikes, than I choose to remember.
Paul: Thank you.

Carbon Rims
For the last week, I had the exciting project of testing the benefits of Carbon Rims on a Honda CB1000RR, for a magazine article.
This involved running power and torque tests with the steel versus carbon rims. The results surprised even me, and I shall post more once we have cleared the contents with the magazine (re copyright stuff, you know!).
