				Dramatic price drops
			 
			
			
			Hey guys and gals, an increase in competition has forced us to make significant reductions in prices of our compression tester systems. Check out the new pricing. This may be your last chance to get one of these systems. If sales do not improve soon we will be shutting our doors for good.

			I hope business picks up for you. There are too few making products for our cars as it is. 
		
		
		
		
		
		
			It would figure that if I finally get enough money available to purchase one of these systems, they will no longer be available.

			Thanks for the good wishes!  
		
		
		
		
		
		
		
	Unfortunately, it is difficult to make a reasonable profit from rotary products because of the relatively small customer base of rotary-engine enthusiasts. And when competition comes into the picture, any businesses "piece of the pie" can be cut. Guess it's the way a free market economy works.  |

			I've wanted to buy one of these for myself, and for some time but not being a mechanic and only using my compression tester a few times, , this was never an economical purchase for me. . . Maybe one day, if these are still available but in my honest opinion, these are too expensive for the everyday hobbyist. I'm looking to spend no more than a hundred bucks. Making my own may be in my best interest. .

 FYI-Our first systems back in '06 used the hose in a similar arrangement to the re5 thread. However, we quickly went to our current system when we discovered that the internal volume of the hose affected the accuracy of the results. The duration of the compression pulse of the rotary is so short that the volume of the free space in front of the pressure transducer was not fully pressurized within the hose during the pulse.  |

 Most of the hardcore rotary guys are tinkerers with a little bit more mechanical inclination. Most of us aren't riceboys or buy our cars just to look good. MAP sensors are getting cheaper and cheaper every day... μP's are getting more prolific - check out any of the Ardruino stuff out there. Most have the skills to build their own systems. Then you got the cheap-asses who get away with a basic compression gauge... You're right - trying to make money off the rotary crowd is too small. Either you have a niche product that costs a LOT, or you *TRY* and make slim profits off of little stuffs. Until another TURBO rotary sports car comes out, the sales are limited. -Ted  |

			I've always used the best products out there and some of the shit on the 'market' is simply a reflection of the customer base, be that dog shit apex seals for $300 or nintendo game boy compression gauges powered by portable dildo  batteries ! 
		
		
		
		
		
		
		
	When my OG unit dies I would consider ones like this (if still around).. This is the one I currently use, been with me for 10+ years and its great! corrects to cranking speed and can log too if you need it, switch units on the fly and works on piston engines as well with long reach sensor to get inside twin cam heads. ![]()

			I bought one of the 4 rotor compatible models about a year ago and have yet to use it, but I wanted to have one that I could use on all the cars in the area, even if I don't have a shop.  I still need to get two more acquisition units to actually do a four rotor though.
