I had trouble when I first started using it with the shrink-wrap sleeve around the sensor slipping. I couldn't even get the sensor hand-tight, so I had to cut the sleeve off. Now it works fine and looks shiny.

Random Q: Would this tester work on a piston engine?

He hasn't been on since September 3 last year. I wouldn't count on getting an answer. You might try contacting him through twistedrotors.com.

I did. http://foxed.ca/foxed/index.php?page=rotarycalc

I checked it against a few of the other converters floating around. Mine seems pretty much the same as the others, aside from me taking the engine correction value into consideration.

Is this still available, or has the group buy closed out?

Well, this unit works well.

Just a little too well, if the stark truth isn't what you wanna see.

Installed a new blower on my '04 GT with only 15K miles on the motor.

Won't start. Tries, but won't catch and run. Truly epic flood symptoms.

After performing deflooding procedures, oh, about a zillion times (OK, only about a hundred), I hook up the tester, which worked perfectly.

Both rotors, all face values in the 50's. (That's "fifties", as in "5-OH", or "Fiddy")

Apex seals are obviously hibernating deep, deep in the rotors, and I don't think they'll be coming out in the spring. Long story, but I think the previous owner somehow managed to carbonize the motor (see: carbonite/star wars/impenetrable encasement system/jabbathehut)

But hey, at least I know what the problem is

Put some tranny oil through the spark plug holes to build compression and try again.

Has anyone been able to contact the inventor? twistedrotors.com is still up; but attempts to order through the website fail (both blue and green show as out of stock as soon as you try to order either one), and all of the emails and PMs I've tried sending also go without any response. I even tried contacting the inventor through the inventor's youtube account. I'm not expecting the group buy price; but I still want to order one because I am pretty sure my compression is fading fast; but I want to be sure.

The group buy closed a while back. You might try contacting him in the 7 forum. He said he spend a lot of online time there. The tool works great........

Thanks. Been trying that, so far no luck, I keep hoping that eventually it'll soak around the springs and seal and let them release.

Keep trying; I do know this guy is busier than a Mazda Mechanic de-flooding RX8's. The unit is very nice, I feel very lucky to have gotten one.

Do you manually turn the engine to put a teaspoon of oil in each rotor face?

Have you considered you have a blown engine?

Wird, yeah, did that. I bought this car with 14.5 k miles last summer; put about 1000 miles on it, ran well, got normal mileage, no starting problems at all. Had a Cobb Accessport on it, uninstalled that, car ran fine, no problems. Put the blower on, suddenly it won't start. Been over the blower installation, can't find any problem. Have fuel, fuel pressure, hot battery, new plugs, new coils.

I can't understand why it won't start; the startup map for the Pettit blower is pretty much the same as the stock map. Right now the only thing I can put my finger on is the abysmally low compression readings.

Blown engine, maybe, but I just checked, it didn't have a smile on it's face or any lipstick on the exhaust...

By blower, do you mean the pettit supercharger? Maybe you have a vacuum leak somewhere, did you plug the map sensor back in?
