This was posted to our rally group, I thought it contained some useful advice, so I'm posting it here for all members.

Disclaimer: Whilst I advocate polishing & porting, I can't really advocate this method!

"Hey guys, I've got a 98 WRX. I 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.

After running the car and letting it suck in sand we got about half

way through a 25 kg 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 Subaru

NO NO NO! yor supposed to use metal shavings!

I honestly hope this is a goof. although, I guess you can never be too sure :stupid:

I agree with St.stephen.I must assume this is a joke.If not and you let your friend do this---as they say if dumb was gasoline ,you wouldn't want to smoke around him!!!

Please note the disclaimer. What he SHOULD have done is add a thickning solution to the sand. Thus he would have extrude honed the ports. Much more effective!

Actually I think the disclaimer was to (hopefully) point out to people that it was a joke, but you never know these days........

It is after all, in Funnybone isn't it?.....

Maybe someone should have mentioned using glass bead, so it would just roll out the exhaust pipe easier..... :devious:

Ah, 2Many, you've lost you're marbles!

ROFL ROFL

I never had any marbles to play with when I was growing up...

So how could I lose them?

If you increased the revs, would the pistons erode enough so that you'd have flat-tops, or would you just get lower compression so you could run higher boost? ROFL

Meanwhile...if that is true, it just confirms my opinion of most WRX drivers aged 18-25!!:classic:

That is pretty much the dumbest thing i have ever heard. (Provided that was a true story). If so, I like how his buddy claims to "tune" hondas. It seems like these days, if you are between the ages of 16 and 22, you are classifed a "tuner" if you can install a cold air intake or pay somebody to put a 5 in. pipe on your muffler.

Same crap different car http://forums.audiworld.com/a4/msgs/1567770.phtml

I think it's a joke to see how fast it spreads...
