Don't you mean how NOT to port and polish a cylinder head?

it was faked, btw

What a dork. Everyone knows that you shouldn't use sand to do this.

I just smashed up an old concrete path into 5mm bits and dropped them slowly into the intake (filter out of course) while on a dyno. After 3 minutes, the increase of power was 36 RWHP. Next week I'm going to try using 12 gauge shotgun shot, I've read that it's the easy way to "peen" the intake, just like golf ball dimples.

Sand.....sheesh!!!!!

Wow, I can't believe that thread is still making the rounds .

bullshat

I like the "sock in the BMW engine" post better. At least its believable, unlike that one.
