My results were ~110 psi on every face of both rotors. This was at 20,000 and 26,000 miles on the car.

I figured I'd throw this in the group buy thread so everyone has some sort of base line.

Edit: I was the tester for RX-8's.

Yep, give me a call when you get a chance. Haven't heard from you in a while.

I'll take a Blue LCD. You'll have the money within a couple days. Now, question...I have a long name, will Property of ; Paul Peitzmeier fit?

Seeing as how I've had an RX-7 stolen from me, I want this to be rather secure with me.

Hi Paul, your first and last name will fit just fine on the bottom line. :)

sweet tool. i should get mine checked before i put my turbo on.

TwistedRotors 04-30-2009 09:47 PM

Update: Well I've been soldering most of the day, and the fumes are really starting to get to me. LOL! I've also received the parts to build the cases and the sensors, unfortunately I only got 9 sensors. With the 4 I already had, that puts me at 13 units vs 14 that I originaly was going to be able to ship prior to the 15th. The company I'm ordering these from seems to be having a hard time keeping them in stock. They will have more in stock on the 15th, but I've contacted another supplier as well just in case. I'm not sure that they'll do business with little 'ol me, but we'll just have to see. All during development I was the only one ordering those sensors, now someone else obviously is.....perhaps someone here is building their own tester? :suspect:

fumes are bad, mmmkay :lol:

How long is the cable? That is, do you need someone else to crank the engine?

The cable is ~36 inches, when testing my FD I can place the tester between my raised hood and the windshield and see it while cranking. I'm not sure if that'll work since you RX-8 guys go through the wheel well. It shouldn't be a big deal if you can't see it, as the reading won't go away when you stop cranking. So you could crank your engine over, then get out and look at the tester. Texak just tested his car, maybe he will post and let us know where he set the tester.

I know...I'm really sorry. I'm working on a solution, but I don't want to say more until I'm sure it's going to work.

But presumably the last numbers are taken during the period the engine is running down, and so unreliable. This is one of the reasons why I asked you in your other thread about displaying a final average. Those averages would be the numbers you will write down, rather than the ones you derive mentally from the couple of hundred that flash by during the test.

The final face of compression is traditionaly low, however it is not necessarily shown. The screen is only updated on every other rotation and then only after it reads 3 compression pulses. Basically, you have a 1 in 6 chance that the final face of compression will read low and cause the screen to update. This can be seen in 1 of the 14 tests that Texak did on his car. His results are posted here: https://www.rx8club.com/series-i-tech-garage-22/results-tr-01-rotary-engine-compression-tester-172766/ . If it happens to someone else, just crank the engine over a few more times and look at the screen again.

Hi everyone, sorry for the lack of updates...but I've been busy!!! First 10 testers are out and 5 more should be done and out before Friday. Keep an eye on your email as I'm sending out a notice to you when your tester ships. I've got a pretty steady stream of parts coming in, but I'm still trying to get the hang of this whole inventory thing and keeping everything organized.

wankelbolt 05-13-2009 10:56 AM

czar 05-18-2009 07:04 PM

chickenwafer 05-19-2009 10:39 PM

I still dont have any injectors so my UIM is just sitting there. I dont really know if I can test compression with the throttle body and all disconnected. Will test as soon as I have the car back together.

Maybe I can get Kersh to come over and test compression on his engine
