bdoz Posted December 4, 2011 Report Share Posted December 4, 2011 Hello, just saw this in jegs email, has anybody used this unit yet. here is the link http://www.aemelectronics.com/dyno-s...hicle-dyno-73/ It looks very interesting,I might have to get one to try out.

Alex L. Posted December 5, 2011 Report Share Posted December 5, 2011 It's a very interesting concept. I'll be interested to see if they're actually any good. Quote Link to comment Share on other sites More sharing options...
ImUrOBGYN Posted December 5, 2011 Report Share Posted December 5, 2011 It's a very interesting concept. I'll be interested to see if they're actually any good. This. Read about these about a week ago. Been wondering how well they'd work. It'll only be a matter of time before those of us who can't afford to risk, find out.

DavidBaustert Posted December 5, 2011 Report Share Posted December 5, 2011 Its just a rotational strain gauge and a digital encoder wheel. It measures torque with the strain gauge and converts it to HP. I built one of these for a design project using labview and an industrial rotational strain gauge used on fracking pumps. Total cost was around $150. The head of the ME department wanted to use it for an engine dyno for the thermodynamics class here at UD. I designed and CNC'd a flange to go on their 350 crate motor we had set up in a jig already. Designed and programmed the controls for the engine as well as had sensors (coolant temp, RPM, EGT in every runner, and also a mass air meter as well as a flow meter for the fuel [to calculate BSFC to calculate HP and compare]). After all the work was completed at the end of my freshman year, the engine dyno was ready to operate, worked all summer, came back to school to find they had torn down the ME building and scrapped the dyno. Son's of bitches! Quote Link to comment Share on other sites More sharing options...
Mallard Posted December 5, 2011 Report Share Posted December 5, 2011 My former coworker build one as a design project in college probably 10 years ago. It was installed on his chevelle, but i don't know how durable it turned out to be. Quote Link to comment Share on other sites More sharing options...
DavidBaustert Posted December 5, 2011 Report Share Posted December 5, 2011 They can be durable if you design that in mind. We had alot of problems with noise in the signals so we had to end up doing an mean measurement of each signal at a sampling rate of 1kHz. Their pricing for these is actually very good if the rotational strain gauge is up to par. I remember calling the company about the fracking pump strain gauge and they told me it was 15k retail. I almost shit my pants. My adviser called them and they worked something out along the lines of a mutual donation. Quote Link to comment Share on other sites More sharing options...
thorne Posted December 6, 2011 Report Share Posted December 6, 2011 HArget just got back PRI and was telling me about this. I believe if we stay AEM marks car will be getting outfitted with a slew of new sensors because of the new AEM hotness Quote Link to comment Share on other sites More sharing options...
