I like the guys thinking and willingness to try new things but that is just such a bad idea in so many ways. I'm waiting for his catastophic engine failure post coming up next week.

seriously dude . . .like an *** . . .I don't even know that much about mechanics, just what I've learned from you all (mostly DJ) and I know that this is a bad idea . . .although, I won't hate on the mans stuff, if it holds up . . .it holds up . . .remember, I also think welding the diff is a bad idea, but it works.

Yeah, I was reading through, then I reference-searched the books, and I learned a lot . . .then I re-read those links you sent me . . .the ones from Garrett . . .and then it clicked all at once . . .it seems that, from what I've read . . .a build up of carbon or any deposit on the fins would cause a disruption in it's overall rotation.
I didn't know that 150,000 rpms was an average rotation speed for those fins and that they each can weigh as little as 15 grams. So if you take it up to 20 grams (which is only adding 5 grams) you've produced a 33.33 percent increase in rotational mass on just ONE fin. At 10,000 RPMS that rotational mass increased up to 25times . . .so at 100,000 RPMS thats an increase of rotational mass by 250 times.
So 5 times 250 is what . . .1250 grams . . .that's 1.25 kilograms or 2.75 pounds of ADDITIONAL rotation weight on a 15 gram fin . . LOL!
I do love me some math . . . I'm no mechanic . . . but I am a scientist, LOL, and cars and science tend to go hand and hand.

omg rofl. The krispy kreme one made me lol.
EDIT i just realized you stole it from a Supra forum lol.
If you read the entire thread on the mazda forum you'll see the thread has spread like WILDFIRE.
