Not your typical gears...
Hey guys, just thought I'd show you something I've been working on in my free time. At work we have some polishers that are pretty awesome, we use them for cranks/rods/etc. Well a few of us have run other things through them since everything benefits from stress relief and lower friction as well as oil shed. I won't post any numbers since I don't have the sheets in hand, but the dyno gains I've seen from this are substantial so I decided to do my gears, let me know what you think!

They aren't the best pictures, but you get the idea. If anyone would be interested in this, shoot me a PM.

That looks very interesting. I remember you saying you had a little secret for your motor as to why you are pushing more horsepower, close to 400whp on lowered compression. Guess that's the secret! Lol

I can't tell you what we use, but I can promise you its not walnut. In the first picture that's just Styrofoam from the packaging they came in.
Gear wine IMO is caused by the installation, not the gear itself. That being said, these could allow for things to not have to be quite as perfect.

One last question, are you saying that the polished gears are makin big gains or the internals? I was under the impression you meant the internals but after reading the posts again I think you may be tlaking about the gears? I guess you can attribute some horsepower gains to oil shedding but nothing noticeable I would think... Could be wrong. Kinda like how knife edging a crank allows you to shed oil and rev higher.

I just changed to 4.10s. I have my 3.31's in a box outside. Any pointers on how to get the stench off of them? (they smell horrible, I cannot even bring them in the garage) My will make me sleep with them if I do....
