What is the difference in the process of Mirconite and REM Polishing tranny and ring/ pinion gears?
Which is better?
Which will reduce more drag and free up more HP?
Also what is your thought about Cryo?
Pro and con’s for all?

I believe that micronite is an abrasive slurry, whereas REM is a chemical process. I have some experience with both, and for what I've seen and heard they seem to achieve the same result.
I heard the hype about Micronite while on the power tour. They claimed a typical GM 10-bolt ring and gear micronited freed up an additional 15hp and 15 tq. If that's true, that's a damn good hp/$ mod considering the cost is around $300 I beleive + install costs.
this could be very wrong, VERY, plz correct me if i am wrong
i believe that mikronite is a finishing process used to reduce temps, when i called and spoke with amber and joe@t56rebuilds.com, they said they would recommend that kind of thing for road racers and autocrossers that are gonna be in the high rpms alot. not sure on a power increase or a strength increase, i would have to dig deeper into the subject.
cryo is a process that actually strengthens the gears in the transmission by freezing them to like 300 below zero and then heating them back up i believe. I believe that this process straightens out the molecules in the gear itself and makes for a stronger unit.
hope this helps. this is all transmission information, not ring/pinion/rear end knowledge here.

Thanks, I am looking for tranny info now.

I do beleive that Microniting using walnut shells at high pressure to polish the ring and pinion to the point that they are so smooth and polished that they actually look chromed. This supposedly reduces the frictional losses.
Sounds great in theory, but I don't have any personal experience with it.
HRP World specifically, is known as one of the best in the business and has better pricing than most due to their volume of work. Here is the direct PDF for their services dealing with REM specifically REM finishing.
Sounds like a great idea for people going to 9" or 12 bolts. You could gain back a little of the hp lost to larger gears, and the increased drag associated with them.
Which one is better? At first glance REM sounds better.
Does anyone know of a shop that does Mirconite and or REM?
I beleive it was Crane Cams that has exclusive rights to the micronite process..(done with walnut shells) ..they had a very nice slick paper hand out on the Power Tour that made some large claimes..as with all advertising I am skeptical to say the least.. ..their claimes would be good if only half of it were true...I don't have any positive or negitive feedback on the process except for what the guy on the tour was telling me and their printed info sheet.. if it was in fact 100 % true it would be a good mod to do to parts for longivity and less friction..

REM looks like electropolishing. May be somewhat differnet, but it was a chemical polishing process that would have a similar effect. Wher I had seen it dones was a tube bundle for a heat exchanger. The bundle had to be food grade, so the entire bundle tubes and welds were electropolished which was the only way to reach every part of the bundle.
We have been utilizing micro-polishing, cryogenics and dry-film lubricants in our high performance differentials for over 3 years now with outstanding results and each certainly has it's place in specific applications. All of these metallurgical treatments are nothing new and is/has been used in the aerospace industry for decades now, with it only starting to trickle down to the HP automotive industry as commonplace within the last 10-15 years or so. When performed properly, it's quite effective.
Have you done an A-B test of the treated/cryo'd/DFL diff to see what if any measureable gains you saw? If so, what were they?
Micro-polishing: We've measured a direct drop in mean differential lubricant temperature of 12* to 16* using MP finishes compared to standard, as machined finishes utilizing a thermocouple temperature probe inserted in the sump of a C5 Corvette differential case. Great for high-heat environments like road racing and auto-crossing.
DFL: We've set up some drag racing only differentials with this and one that is competing in Speedweek at the Bonneville Salt Flats this year to reduce parasitic drag at elevated ring gear RPM. Combine this treatment with MP and one can effectively run the differential purposefully low on lubricant to reduce internal windage AND reduce drag by being able to run very light differential oils to further reduce parasitic drag w/out burning up the ring gear from excessive friction due to lack of lubrication.
Old racers trick we used to use back in the day...ran 0w "sewing machine" oil in our racing differentials when we competed in Stock Eliminator in NHRA to pick up a few hundreths in very competitive classes. Basically as long as the gears got just barely "wet" to stay lubed, all was good...
Cryogenics: We were the first to pro-actively use cryogenics in the C5 and C6 Corvette platform about 3 years ago to promote long-term gear life when used in a wide range of applications-including racing. Quite effective on the relatively soft (promotes quiet gear operation) C5/C6 ring & pinon sets and our warranty claims were cut in less than half the moment we began using cryogenics as standard in ALL of our differential gear sets regardless of build stage. We've never changed those policies/methods to this very day.
Mirconite vs REM Polishing and Cryo? 
..their claimes would be good if only half of it were true...I don't have any positive or negitive feedback on the process except for what the guy on the tour was telling me and their printed info sheet.. if it was in fact 100 % true it would be a good mod to do to parts for longivity and less friction..
