More out of curiosity but anyone know if a reasonably priced compression tester for rotary engines is avalible? Only one Ive ever heard of is the $2k one from Mazda.

 

go to twistedrotors.com

 

there's also www.rotarydiagnostics.com

 

He got busy and stopped making them with no ETA on when he'll resume. Kinda sad, I got a chance to rent one and liked it a lot.

 

Twisted Rotors was cool but as mentioned not available at the moment. I've heard several people speak highly of the product from: http://www.rotarydiagnostics.com/

 

honestly, i used a regular compression tester. all i did was take the "valve core" out of the tester and performed a compression test. as long as you have someone crank it as you watch it "pulse" but thats just me. no need to buy a 2k compression tester

 

WOW I really need to look around before posting... I JUST asked this question like two minutes ago...

I feel like a tool (no pun intended)

 

I have the one from Rotary Diagnostics Systems, great tool.

 

can i borrow it?lol..... i think a reg. comp tester will do like dude said

 

what is psi reading i'm i looking for ,with a regular comp tester?

 

^ Any regular piston compression tester will work, I don't know their PSI range 0-160 maybe? You won't get high number with a bounce test anyways, unless you keep the valve in and measure the overall number which is not very useful.

If you are local sure

 

I got my Mazda Compression Tester tool for a really good price, 2K? hell no



MY precious ...

 

it will bounce with each "power pulse" as long as they all read the same about 6 times, your ok. but only pull one plug for each rotor...i was an idiot and pulled both the first time
