port & polish your heads
« on: January 01, 2009, 06:52:54 AM »
Well Guys I have found a new way to port and polish your heads without removing them.Tell me what you think.

Quote
   Hey guys, I've got a 98 1.8T. I've had a k04 and chip for a while and wanted to get more performance. I was recommended to port and polish the intake and exhaust. We found out they used abrasive material to do it like gritty sand. So I got with my friend that tunes Hondas and we decided to try it ourselves. We got a bag of sandblasting sand and hooked up into the intake and started the car. We had to hold the gas so it would run. He wanted to let the engine suck in the sand through the intake so it would port it out and then push it out the ehxaust so it would port the exhaust manifold.
I was worried that it might cause problems but he figured it'd be OK as long as we didn't make boost and it get sucked in the turbo. After running the car and letting it suck in sand we got about half way through a 25 lb bag. The check engine light was on and the engine was bucking and kicking and sounding really weird. We stopped and hooked the car back up normal and took off the sand supply. We tried to start it again and it was really hard. Once started it couldn't idle and kept making weird noises. We took it out and drove it and it started to make scraping and knocking noises.
Help! Can anyone tell me what to do! My buddy only does Hondas so he doesn't know much about Audis

I find that glass beads work a little better than sand.  It really helps to modify the exhaust after a port and polish.  Check out this mod-  http://kalecoauto.com/index.php?main_page=product_info&cPath=3&products_id=10&zenid=be0cc03b66070491243addd691b9ac94

   Smokey Unick used to build some off the wall engines back in the day .   I read an article once where he pumped a mixture of water and sand through a set of heads to port them .  They were off the engine of course. 

   He also once built a small block chevy that ran backwards.  His theory was it would counter act the body roll of turning left .  A normal engine tries to lift the right rear tire and plant the left front increasing body roll.   His engine would plant the right rear tire and lift the right front .   It never really caught on , kinda like running sand through your motor to port and polish.....lol
