Dynamometer torque converter

So knowing how much the converter slips is a no brainer.. Torque converters transfer a consistant amount of power when propelling a vehicle at the track. So why can't that same power that the wheels see be measured accurately?

Perhaps slipping stall converters reveal the apparent shortcomings of how dynos measure power.. In other words, use a chassis dyno to get a baseline power number, then make a change and see if power increases or decreases. They are best used for tuning, not an accurate HP number. I think if you hold to the same theory as me it really makes all this hubbub about TQ converters and accuracy a mute point.

You just need measurement consistency run-to-run, who cares about the actual number? Steve - Never used a hub dyno but the concept certainly has merit. Is the Dynopack a water brake, Eddy current, or??? Any pics? When I wrote my dyno article I researched them a bit but was unable to find anyone with hands on experience.

Evidently I've never lived close to a facility that used this device so I can't track one down. I would certainly be willing to run the Buzz Bomb on one if it was available. One other benefit of the chassis dyno is opportunity to get full power cycle pulls without going a mph or whatever as this is also how you can test cooling system integrity, identify leaks that only show up under pressure and generally see how the drive line behaves.

This is particularly useful in these days where many parts of the country have fewer tracks and opportunities for on track testing. There is no substitute for on track testing as that is what we are preparing for usually, but I like having a safe baseline tune and knowing that I'm not going to dump something under the tires at the top end of the track.

Oh and yes I have a medium stall converter in the car, , and everything came out just fine at Westech a week ago. Their Superflow does adjust for car weight, tire size, gear ratio, estimated stall speed and driveline efficiency etc. I wouldn't recommend doing to a dyno just to find "a horsepower number" but instead, use it as an opportunity to make sure your tune is correct at as many possible RPM and load points.

As Bill points out, it's very handy to have a stationary car, hooked to as much datalogging of vital signs as possible, that you can run up to any MPH and load that you choose Now, as Eric points out, comparison pulls are vital to find out what parts and tune-up parameters put the most power to the wheel. Casey Currie. Josh Blyler and Rusty Blyler. Casey Gilbert. Follow Us. KOH is coming up quick!!!! What a crazy busy 10 days it will be with customers on the lakebed!!!

Happy to see this beauty out at SEMA. We appreciate he opportunity to help out. Excited to finally have this at sema Thanks to all the partners that made this happen wd40 tradronfeldt.

Kept this under wraps for too long. Check out kylelucas25 at LS fest with slickmist ready to rip!! What a way to start off champoffroad season. A few of our customers brought home some hardware this weekend. Congratulations to brockheger for bringing out the broom this weekend and taking top spot on the podium both days.

Hell of a race by kleiman42 with an epic drag race off the final corner on the last lap in his Pro2 securing the second place spot on the podium whoneeds4shocks. This would be a weekend that a component supplier to race teams dreams of The teams we are contracted to supply are no joke Our hats are off to the teams that choose our product and support over other suppliers.

They go the extra mile to get the job done and we are appreciative of the opportunity they gave us to be involved in their programs.

I will let you guess. Our transaxle dynamometers are built with advanced motor and drive technology and utilize AC dynamometers to achieve superior response times as compared to those that utilize DC dynamometers—this results in much shorter test cycle times. An added benefit of AC dynamometer technology is the ability to electrically lock and unlock the output dynamometer during the testing sequence, allowing torque converter oil to be circulated and cooled between data sample cycles.

Additionally, our transaxle dynamometers allow for precise control of torque, RPM, temperature and pressure, which means exceptional test repeatability and test data accuracy. Our transaxle dynamometers can perform transmission efficiency and durability tests, performance and durability tests of gear shifting unit and synchronizer, performance and durability tests of axle gear set, and differential gear and differential case tests.
