Hey guys, I've got a 2009 C63. I know it has 451hp but i've always 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 go over 5000rpm. 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 AMGs.

I think you have just damage your engine!! AMG is way lot different than Honda!!!

And I think your car is not drivable now!!!!

I think you accidentally read the instructions for porting and polishing the heads from a snow blower motor.

My dealer didn't tell me about the Sand Vaccum Option! Doesnt seem to be worth it.

Dude are you Serious?

Sure it was sand and not lines of the stuff you seem to be snorting?

Pull your dipstick and let us know what you find on it.

He's BSing all of you, I'm sure of it.

Hopefully you're just messing with us and this isn't true!

Did you remove your air filters to make this technique more 'effective?'

I just checked the dipstick and noticed a bit of sand on there.

*update*

I just added 3 liters of motoroil into the engine because my friend told me it would flush out the sand, its now spewing smoke everywhere

Did you really truly do this or is this a joke?

hahahahaha this has got to be a joke

Hey, I am the buddy with the Honda, a fit to be precise. I don't know why it fukted up his engine, I read it on the internet that will make the engine rev faster and flow better. Ken was so enthusiastic about it so we decide to try it out.

it's running really rough right now.

4matic

hahahaah this is the most stupid thing..

SebringSilver

Oh damn, I think he may be serious afterall.

WTF, Yooker?? Why the hell did you do this? Have you lost your marbles? You know that sand trick only works on Hondas and sometimes on BMWs, right???

*update*

I just came back from trying to flush out the sand by spraying water into the intake, i have my filters off so it would get the sand off, hopefully it helps

*update again*


the car just shut off and won't turn on now

SebringSilver

Wait, did you use distilled water or tap water?? I'm pretty sure the Honda guys used to use only distilled water for this.

4matic

HAHAHAHAHHAHAHAHAHHA

yooker

well i mixed some dishwasher and normal tap water and basically poured it into the intake through a bong contraption.

yooker posted in the age thread that his parents bought the car and he shares it with family.... unfortunately I don't think he's old enough to have developed that sort of "sense of humor." However he is likely young and gullible.

yooker I don't think anyone has an answer for you, because we have never forced our engines to breathe approx 12.5 lbs of sand..... ?!?!? That's why we think you're insane.

Where were you expecting the sand to go, as it travelled through your intake and "out the exhaust"?????

Craziest thing I've ever read on a car board.

SebringSilver

I don't think you're supposed to add any dishwasher solution, you nutcase. I'm not sure where you're getting your advice from, but he/she clearly knows nothing about how to remove sand from an engine.
