Actually... if this does come through (here's hoping!) I'd like to take the airbox off of someone else's 8 and observe the way the throttle plate behaves. That'd help me a hell of a lot in my diagnoses and repair of my issue.
I have a bluetooth OBD scanner to log some data, as well. It'd be really sweet to have some data to compare to.

- Coils
- Wires
- Trans fluid
- Diff fluid
- Brake pads (all)
- Brake fluid
- That stupid flimsy bracket that holds the little nub on the ignition key hole for comfort access
Also, 10:30 start time works for me! Where is the shop? Let's get a location posted up. Let's also plan for an early-ish dinner afterwards.
Also also, thanks loyal8! This is awesome!

"I love it when a plan comes together" (from the "A" Team). I will be there at 10:30a . Let's just post up the address so no one gets lost. Thanks again to all, especially loyal8.
Just spoke to Dave (compression tester guy) He is in for the 12th. He is keeping me posted on time. Who is interested in getting there car tested? $40 per car (dealer charge $150+)
Ill leave it to Loyal8 to post the address to the shop.

Never done trans or diff fluid. The rest I have done and is pretty easy (depending on pesky bolts!)
gwilliams6 is in for a compression test for $40.
Hey everyone this is Dave with the compression tester. I met some of you at the delaware riverfront this past spring. I had the grey turbo RX7. Sorry I couldnt make it out this past weekend but between weddings, family parties and disney Ive been unavailable.
Here is the compression tester I purchased, Model ReCT . I've used it on my car so far and I am looking to do a few extra tests of other cars to offset the purchase cost. If it will entice you guys I am willing to do a follow up test a year from now for free. Right now I really need to recoup that $400 though

one question for Dave. Have you done a compression test yet on a RX8 ? Looking through the links to instructions for your tester, I don't see instructions for the RX8 Renesis engine. Maybe I am just missing something.
I have not done a RX8 yet. I can email him to verify it works on an rx8 if that would ease your mind, otherwise I dont see why it wouldnt work. The housings are nearly identical to older 13b housings, you guys just dont have the right exhaust port
I downloaded the instructions for the tester you have. I read it extensively and it looks like the key data for an RX8 is
"The workshop manual for the RX-8 states the “standard” compression as 120 PSI at 250 RPM,
and the minimum as 98.6 PSI at 250 RPM. Standard difference in chambers should be within
21.8 PSI, and difference between rotors within 14.5 PSI."
There seems to be a fair amount of calculating involved to get the reading for the cranking rpm . Important to have at or near 250rpm during test, or normalize it for the cranking rpm and for sealevel. The software on your computer hooked up to the tester has to be set up and reading the data does require some time.
I am saying all this can be done for sure, but even the instructions say this tester does not give the direct result readouts like expensive dealer compression testers. It is still worth the try, but it may be a more time consuming effort, so we should take those folks who really need it more in the time we have the shop. What do you folks think ?

In the instructions he includes the formula to figure out the cranking RPM. It only takes a minute, and once the math is done for the first car, you substitute 2-3 numbers, plop them in and you get your cranking RPM.
Gwilliams6, so far it looks like it will be 4 of us looking for compression tests. Myself, yourself, Iamfodi, and Enaris. We should be able to get this done in the 4-5 hours we have as a group.
