So a while back I got some used gear sets from someone we knew. These were G-force gear sets for a T5. Well, the person who sold it to me also helped set it up and from what me and Bryant figured out he didn't set them up right. So the gears wore out real fast. He sent them back to G-force and look what they sent back :bananaman They sent us a complete new set WITH 5th gear set as well AND they REM polished them. I dunno what REM is but look how shiny the gears look.
The REM process is a finishing technique that lays down a thin metalic film on the parts and the placed in a vibratory polisher that removes the smalll raised portions on the parts. This leaves a finish that is smoother than the part could otherwise be. The softer metal helps to fill the pores and eliminated from the actual wear surfaces. when it is done after cryo-treatmentit makes a part that is harder and more resilient than the original part. Without the cryo-treatment the part has a nice finish but remains no stronger that the original part - it just has a better finish. It does have some worth-while advantages but strength is not one of them.
so paul are you saying the gears should be cryo'd before they were rem treated or can still be cryo'd?
Even without the cryo treatment the parts will be much more resistant to breakage due to the elimination of potential stress risers as breakage points. What kind of power are you looking to put through this thing?
probably in the 450-500 range. the block is stock so that's probably the most it will handle with a blower
I wouldn't presume to tell a businessman how to run his buisiness but I would want the gear train of any transmission that was going behind a 450 - 550 hp engine cryo-treated more than to have a nice finish put on it. I am odd that way... I want things strong more than I want good-looking. There is a lot of profit in selling good looking and good sounding parts though - as evidenced by many parts businesses.
As usual....Paul is only giving his opinion of REM treatment instead of actual facts. Here are the facts. The process is an isotropic surface finishing process that produces a non-linear, low Ra that improves wear properties and reduces friction. It is a chemical - mechanical process that sequentially removes the "peaks" of a ground, cut or honed finish while leaving the "valleys" unaffected. The end result is a dramatically improved surface finish with insignificant dimensional change of the part. The increase in component life is a result of a flatter contact surface, which distributes the loads over a larger area and inhibits the formation of stress risers. REM is more than just creating a nice, shiny part.
Here is a description of the process from Taylor Race engineering: "SOLUTION: REM(tm) ISOTROPIC FINISHING Although the result of the REM(tm) process is a beautiful finish, it is Important to realize that the system does not polish the part. The process involves two steps. The first, referred to as the refinement process involves a chemical interaction on the surface of the part. A soft, thin (one micron) film is formed on the surface of the part. The part interacts with the ceramic media in a special vibratory tub, this film is physically removed from the "peaks" of the processed part and the "valleys" are unaffected. The chemically induced film re-forms only at the peaks that are interacting with the vibratory media, and the process repeats itself. Over time, the peaks are removed, leaving only the valleys, producing the improved micro finish. The second step is referred to as the burnish process. After the required micro finish is achieved, a mild alkaline mixture is introduced. After a relatively short period a polished, chrome-like finish is produced. In addition to the polishing effects, this step effectively removes all traces of the film formation from the refinement process" And from Evans Performance: The REM (R) procedure is not a polishing process but rather a finishing process. REM (R) is a chemically accelerated process which involves two steps. The first step, referred to as the "Refinement Process", involves a chemical interaction on the surface of the part. A soft, thin (one micron) film is formed on the surface of the part. The part then interacts with the ceramic media in a special vibratory bowl. I believe I paraphrased the process in my post very well. An acid bath contains and deposits the material on the parts and then it is polished by a vibratory process that involves a ceramic media. I believe my post was more factual then opinion. Where did I go wrong?
Right here. Why not leave the higher tech racing answers to those with the actual experience so you don't have to "copy/paste" your in-depth knowledge into a post.
The process does not change the metal in the gears. The metal is not strengthened - just the finish on the metal is modified. The steel is not harder or more resilient - completely unchanged. It isn't stronger. That is a fact just like a polished spring is no stronger than the umpolished spring - it is more resistant to cracks but it is no stronger. If you don't like the facts then keep on ignoring them.
The metal is more resistant to cracking/fracturing from stress risers. Therefore, it is stronger. If you don't understand the technology then just keep on blabbering. You can't win this one, Mr. Retired Wrench-Slinger. I'll put my Mechanical Engineering degree against your internet search skills and self-promotion anyday.
