Winter must be on racers minds!
We've been getting a LOT of requests thru Messenger, for upcoming Fall track dyno tuning. I have yet to firm dates, but tentatively looking at coming back to WI at the end of October, or beginning of November.
At JDI, we utilize the latest retrofit DynoJet Track Dyno upgrades from Troy at Xtreme Dyno LLC with their heavy 400 # drum, bearings, and software. In addition for 2-strokes, if you have -4AN Male fittings TIG welded into your pipe center sections, we can also monitor individual pipe back pressure too.
JDI put multiple teams in the winners circle last year, at some of the premier Midwest snow drag events. These sleds came straight off our track dyno.
We have spent the last 2-seasons carefully studying data, and power management on various snow surface conditions. This allows me to mimic the setup we are looking for on the dyno, so we have real world results in the field. We are not interested in chasing "big horsepower numbers", with unrealistic clutching setups. Instead, we'd rather achieve the most usable track horsepower we can in the field, for consistent repeat runs, and 60' power management. This allows our customers to make minor fine tuning changes at the track if needed, based on the changing surface.
We look forward to seeing some of our repeat customers and friends, along with some new faces this season!
