I linked your store on the 2nd page.

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. .

You will be hard pressed to even find a quality pressure transducer for that amount. Pressure transducers with suitable parameters are not generally widely-available, as on the shelf items. Is it possible to find one? Yes, if you look long enough. Ours are built to our specifications and the unit cost is more than one hundred dollars even when purchased in volume.

Yes, you can build one of these things yourself, but we offer a complete PNP system along with a detailed user manual and a support mechanism.

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.

And that's one of the bigger problems...

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.

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.
