Patch Posted September 1, 2011 Posted September 1, 2011 I am on a few other forums and came a cross this, somebody here may be able to help. 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. link. http://www.audiforums.com/forum/off-topic-5/hey-guys-please-help-my-mods-gone-wrong-80267/ Quote

peter t Posted September 1, 2011 Posted September 1, 2011 Why not throw a kilo of sugar in the fuel tank, that should make it run sweet. Quote
Mr Camouflage Posted September 1, 2011 Posted September 1, 2011 You might want to take the oil cap off and stick a sock in there: http://forum.e46fanatics.com/showthread.php?t=311931 And while your at it convert the engine to Direct Exhaust Injection: http://forums.finalgear.com/general-automotive/id-like-to-introduce-you-to-dei-direct-exhaust-injection-22931/ Quote

Patch Posted September 1, 2011 Author Posted September 1, 2011 The site I got the link from reckoned it was real, now if you had of meet my step son you could believe it, He was 32 when he pulled up at home with the front brakes smoking and locked on, I had a quick look and the oil in the master cylinder was red, I said very easy fix just go to a wrecker and buy all new brake parts and flush all the lines, between cones him and his mate decided oil is oil. Last week a friend of mine lent her ute to a neighbor and he was unsure what to put in it for fuel, so he pulled into a garage and asked the mechanic, he looked under the bonnet and said it is petrol, they did 200ks with petrol in a diesel motor , luckily nothing was damaged,so yes these people are amongst us.

waxhead Posted September 5, 2011 Posted September 5, 2011 The theory is good the result is not so good. The issue is you were not porting for the right rpm. If you wanted to make peak power at 5500 then you should have held the engine at that rpm. This way the weight of the air/sand would be pushing on the right places. To low and the sand falls out of suspension and just ports the bottom of the port. You may want to look at grinding on the base circle of the cam to increase the lift as well. You need to use the flkapper discs. Using the hard discs is just rough and you will not a preicsion engine build like you are after Quote

You could even do it at the jet ski race events. Pull onto the beach and through a handfull of sand in the inlet while revving it. Dry sand of course, only an idiot would use wet sand for porting!
