not sure what it is called

[zman98]

I was at the shop where i have the work done to my f-body and i was talking to one of the guys and he told me about some procedure they developed to help strenghing ring and pinions in your rear-end. It sounded like it was similar to sand blasting however it used charge particles that fill in little holes in the metal making it very smooth and very strong. Supposidly they tested this at the track with a 10-bolt and were running low 10's all day long without any problems. Has anyone heard of this or know what it is called?

i read about it in car craft i think. they did a test on a mustang 8.8. the gears were slightly stronger and they got a small boost in power, maybe a horse or two. i will try to dig up the article.

Case Hardening, using Nitrogen, Boron, or Carbon

Material Science Major

[ss~zoso~ss]

the introduction of these elements, changes the structure of the outtermost surface of the gears therefore making them stronger and more reliable

Damn material engineers haha. Mechanical here.

nice, i like it so far just a sophmore

Junior here, coop yet?

[ss~zoso~ss]

na, i'm only in my second semester sophmore credit wise

[ss~zoso~ss]

i'll be going active duty in the Air Force after College, so i'm not really worried about a job after college

MRR23 should know something about it. I believe he was testing some gears in his car but cant remember for sure. Shoot him a PM.

there's a couple of them out there. one that i did testing for, and what you are trying to describe, was www.mikronite.com it's not a coating or freezing. it's process that takes walnut shells with an abrasive compound and spin it in a centrifuge that puts 30-60g of force. the centrifuge spins in opposite directions.

i'm not running tens, yet. they used my car for sets of testing. first one was dyno, wear and temp testing on a set of 4.10 gears. compared unprocessed vs processed.

second test was comparing REM processed, REM cryo and REM processed and cryogenic vs the mikronite processed gears. all were the same brand 3.73 AAM gears. in this test, i swapped out 6 sets of gears in three months back in 2005. all had 500 miles.

some pics i took while i was doing the gear swaps on my car.

the guy they are refering to breaking gears after about 13-15 runs unprocessed has went 200 passes without breaking a gear last season.

mikronite has been around for years. they have been doing treating for the major race teams, as well as government contracts. to get a processing machine requires you and your company to pass background checks to no end. they fall under the national security blanket. the machine requires a ID swipe card for it to open/close. you have to keep stringent records of everytime you use the machine.

just before the PRI 2006 show, mikronite just finished the purchase of crane cams. so, you'll see a lot more of this stuff trickling into the performance automotive market.
