Compression test?
Hello,
NOOOOOOOOOOBbbbb question....
Can a compression test be done on the RX-8? If so is it exactly like a compression test for a piston engine? If not how do they do it/how does it differ?
This sounds weird I know, I am confirming (or not confirming) what a dealership is telling me.
Thank you,
Brian

You dont exactly have to do it at a dealership, as long as the shop you go to has the right equipment its all good.
usually a compression test will cost just 1 hour of labor, but make sure u do it at a dealership who knows what they're doing, not just give you some numbers so you can walk away.

I sometimes will even use a standard compression guage with the valve removed and we also use the old 70s guage that plots a graph on paper.

Paul,
Thank you VERY much. That is EXACTLY what I was looking for.
My issue is I drove another same year/model/tranny/port engine car without mods. Mine (both I and the other person thought) seemed much "weaker" and slower (even at higher RPMs). So I take it to a local stealership who I have had work done at without an issue several times. They tell me they can NOT do a compression test, it does not work that way. So I call another dealer and talk to the service manager and head mechanic briefly. They were confused by the first dealers comments.
I have to pick my car up today so I can go out of town. However Monday I will take it to the "other" dealership and ask them to look into it.
I did take it to a local tuner shop and had a compression test done a few weeks back. They stated two cylinders were running around .75. They stated I might want to take it to a dealership to have it checked out. So I did and then I entered the twilight zone.
It sucks not knowing what to think . Hence my OP.
Thank you again,
Brian

Quick and easy test
This is the shade tree version of the compression test:
Remove the coil trigger wires (you don't want the engine to start or Taz you)
Remove the trailing plugs (the top ones)
Place a finger over a trailing plug hole to seal it.
Make sure you are not near any rotating parts.
Have a buddy crank the car.
You should hear even sounding noises, if you hear loud, soft, soft you should let the dealer check further.
Check both rotors.
Good luck, and be careful.

this is the least expensive "proper" rotary compression tool that I know of, assuming you already own a laptop computer:

In addition, at least one user is running the software on a Mac using the Parallels, Windows emulation program (http://www.parallels.com/).

Actually, you can run this system on any Windows computer--desktop or laptop--under Windows 2000, XP or Vista operating systems. And you can locate the computer up to 16 feet from the tester using a USB cable w/o supplemental power. With a powered USB hub, that distance can be increased significantly.
In addition, at least one user is running the software on a Mac using the Parallels, Windows emulation program (http://www.parallels.com/).
