Default How to Port&Polish your heads without removing them

Found this on another forum, i may try it out this weekend.

Hey guys, please help with my mods gone wrong...

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.

Sounds like a great idea. You should try it Rob. Let me know how it works, and I will do my car. I think it might work better if you use beach sand though.

Park sand works ok for low end power, but beach sand is better high end revving power. But it also deppends on what brand of power band you are using. Come on Traction, this is easy stuff.

When you say beach sand, you need to be more specific. Are we talking coarse California sand? Muddy Mississippi sand? Pebbly East coast sand, or Super fine Panhandle Florida sugar sand? Or we can Get really exotic and go for some of the black volcanic Hawaii sand!

What ever you use, you should follow up with baking soda to give it a good polish!
