Point taken.

I guess it depends on the lube and other variables.
But bottom like, they appear to last longer for me..

It should help life but becarefull on the lube side you need the lube in the meshing of the gears and with alot of EP addiv. so gear mesh does not pust the lube out it needs to stay on the teeth.

The way I understand it is the more carbon you add, the stronger the steel. Low carbon steel gives us stamped steel fenders and panels. Medium carbon steel gives us blocks, cranks, rods and gears. High carbon steel gives us springs and fuel injection parts.

What cryo treating does for us is it transforms brittle austenite into a much tougher material called martensite. A downside to this is the fact that we could end up with what I guess I will call "unstructured martensite" for lack of a better term.

To help illustrate my point, an extreme example would be like pulling all the carbon out of a high carbon steel spring with five coils and putting it back in at the first, second and third bottom coils. By definition it is still a coil spring made with high carbon steel, but the way the carbon is structured makes the top portion of the spring vulnerable.

The beauty of REM ISF finish is that, unlike the very smooth surface left by Mikronite, Rem leaves the "valley" in the polishing, (much like a very fine cylinder hone). This valley is just enough to hold a film of lube on the part. There's a substantial reduction in friction. Combined with cryo (done properly), you get a great part.

Nicely explained Jim, thanks. Jim

I was not in a position to do back-to-back tests with the "Finished" surface treatment, but others I know have had positive responses. It would stand to reason that a highly polished surface would at least have less resistance moving through oil over OEM machined and coated surfaces. A smoother surface would also tend to reduce friction. I wouldn't be wasting my time on it if I didn't think it was beneficial.

no Mikronite, no cryogenic, no EP additive...631 passes to date on my out of the box Richmond Pro gears, 60 footing low 20's to high teens with a best of 1.17 at 3144 lbs. with nothing more than 1 quart of Mobil 1 gear lube.

Just saying.

That's super .....Don't fix it if it ain't broke. Now, how about the guys that can't buy Pro Gears?, or better yet, what if we picked up "your" 60' to 1.15 and your 660 by .03, as has happened ....well.... lets just say a lot. We have chassis dyno tests on several different combos ...back to back to back to back....with 5hp to 11hp to the rear tires. It's not braggin' if you can back it up...(laughing). Also, tell "every" Fuel (nitro) Car that they can no longer run cryo'd (Byrant or Winfield) cranks,or "every" Pro Stock that Cryo'd and Rem finished gear sets are now illegal and see what their response is. One more thing, just for the fun of it, call Timken Bearing Co. and tell them their engineer's cyclic tests on Cryo'd and Rem'd bearings is bullsh!t. JB

No pic?

Thanks for the good info Jim. Will definitely be sending you some stuff

Be carefull of what you ask for.

1. I agree and I won't.

2. it is bragging and just a claim until you are prepared to put your $ and name on the line

Guarantee me that I'll run .05 quicker in 60 foot or I get a full refund and I'm ready NOW to take you up on that offer

3. This isn't nitroracer.com nor is it prostockracer.com

All I'm saying is that most stock/super stock/bracket racer's would agree that 631 passes on an out of the box gear set lubed with nothing more than 1 quart of off the shelf Mobil 1 in a 3144 lb. car running 1 teens in 60 foot speaks volumes as to durability and the need for exotic metal treatements.
