Mike, even before the spintron, there was the "optron". Which I believe was a machine general motors used to study valvetrain motion.

There are alot of false claims on the web about spintron experience from many. I think you should buy one for the shop!

An engine block used for spintron testing of componentry has "windows" cut out of it so lasers and harmonic probes can be set up to measure the dynamics of the assembly.

It's not like a dyno where you take a complete engine in for "testing".

OK, then a SIM is for pressure and rotation testing or break in. but it never fires.

I just googled it. The spin it to 750rpms and pressure test and check for noises. Pretty minimal compare to Spintron or Dyno for that matter.

SIM test examples. Mercruiser reman engines use to be label SIM tested. Actually Mercruiser reman is not done by them at all, it is all done by an Auto remaner in MO. SIM testing has been around a long time. Spintron started in 1993.

Joe, maybe you, Mike or Dan know Bill from Ateco. He is in your area. I think he has a spin tron. Have any of you guys used him in the past?
