I would like to thank Larry at Rotary Diagnostics Systems for his support of RCC! His contribution will go towards the continued promotion of this forum.

Check out his website www.RotaryDiagnostics.com and feel free to post questions for more information on his Rotary-engine Compression Tester Systems.

Thank you! :icon_tup:



Our Rotary-engine Compression Testers combine off-the-shelf hardware and software to create a reliable system that can be used to obtain accurate engine compression measurements from a rotary engine.

Group buy?........

whats the price on that bad boy...?

http://www.rotarydiagnostics.com/pricing%20combined.htm .......found it

Anyone have an experience using this product?

I have had one for 4 years...works well....It is much more complex than the Mazda tester to use the first time..but after you have done it it is quite easy

It also gives you more data than the Mazda tester...

$640 ... no thanks. And $225 for a software upgrade in sampling rate? Alrighty then Motec.

If the two rotor system was reasonably priced, I would have already purchased one.

You do not need the $640.00, 2-rotor system to acquire accurate compression readings on all compression faces of both rotors of a rotary engine. Our basic system allows you to test both rotors, just not simultaneously, and is priced at $355.00. Maximum sampling rate for that system is 240 samples per second which is more than adequate for determining accurate compression readings. Incidentally, the software upgrade is not required nor is it available for that system.

The other systems we offer are intended primarily for engine builders and rotary shops where a higher resolution sampling rate provides detailed analysis of the compression pulses and where the presentation format of the data to their customers may be critical. Of course, we sell those system to individuals as well.

There, now I feel better.:)

I appreciate your very professional response to my post which was in poor taste. My apologies. I guess I'm just a cheapskate.

No apology required, but thanks anyway.:)

LOL...try and buy a Mazda one....even the $640 price looks like a steal then ;)

Well ya know, that could be why Mazda Australia opted to adopt our basic system for 60 of their dealerships. Ya think?:)

Second this?

Third this?

Fourth this?

Thread revival.

Thanks Lance, I bought your basic tester back in 08 or somewhere around there. Lots of bleedy knuckles later I just performed the 50th compression test for yet another happy customer.

Over the years ive sampled quite a lot of charts, heres a select few for your promotional viewing pleasure.


First one is a 20B front chamber releasing its carbon grip on an Apex seal.

Second is a 12A race engine coming out of a one year hibernation (slow starter)

Third is a well build one rotor NSU Spider

Nextmonth im off to the Danish RX club track meeting, where your brilliant tester once again will be on duty.
BTW is there an easier way to send the chart to my customers than "print screen & ms-paint" :-)

Good to hear you are putting the tester to good use. 50--Wow. You purchased the tester in June 2009, BTW.:)

"BTW is there an easier way to send the chart to my customers than "print screen & ms-paint"

Yes, you can email them the ".WDQ" file and have them download and install the WinDaq Waveform Browser software. No charge for that. (http://www.dataq.com/support/upgrades/playback/). Click on the download for the basic version 2.91 at the far left of the page.

Keep in mind, however, they can modify the display settings in the browser so you may get calls asking about some weird display they have configured, accidently or otherwise.

PS: Would you email me the 3 images you posted? They may help me diagnose a customers problem in the future. Thanks!
