Does anybody know what type of metal the piping is between the throttle body and the turbo..??? I am looking into a blowoff valve for my car, and i need to know so i can buy the correct one. I was told it could either be steal or aluminium or possibly composite... For the 2001 t5 model<P>Thanks<BR>SPencer

It is plastic and it isn't really nessecary to install a BOV because there is a recirculating BOV in the compressor housing already.<BR>The car doesn't really respond well to two BOV's........<BR>I tried on my S60, I bought a second pipe from the IC to the TB and installed a special plastic T piece.<BR>I used an adjustable Blitz BOV but it had to be set almost completely closed to get the thing working 99% and that 1% left really bugged me on higher speed/RPM.<BR>The throttle became VERY sensitive.<BR>If you want to disable the standard recirc. valve you would have to take it out of the turbo and block it to make it 100% effective.<P> <IMG SRC="http://home.wxs.nl/~dijkstra/images/bov.jpg"> <P>Edit: If you want the sound you could opt for an open air filter (cone?) but you would have to remove the airbox.<BR>This is a picture of one but the MAF was disconnected at that moment.<BR>I checked inlet temp's and without any shielding it didn't run any higher in temp's compared to and airbox except for a small moment when the car had run idle for a while.<BR>You could fabricate a shield on the left side of the filter.<P> <IMG SRC="http://home.wxs.nl/~dijkstra/images/green.jpg"> <BR><p>[This message has been edited by Johann (edited 07-20-2002).]

I was really looking for the psssss sound that you get from a BOV when you shift gears... Thing is with the intake, I was looking for a spot that had cold air coming in, but i really couldnt figure out a good place. The only option would be through the bottom driver side fog light, thats if i take it out, only downside would be a lot of piping which could screw with the responce.... so... ne ideas?<P>~Spencer<P>

That's one long-a$$ air cone! Are you using it? If yes, does it really complement the upgrades you have done to your S60? Meaning, does it contribute to better response and does it help in providing more power? Is your idle even or rough?<P>Thanks,<P>Yannis<P>

How do you take out the in-turbo bypass valve? Any special tools needed? Also, what do you mean by blocking off, Johann? I am looking into doing something like this also.

Then again a lot of people out there are just doing things without doing much research on them.

Just be glad that there are still people like you and Charles Linden who take pictures of these things to inform people before they jump in and start doing silly mods.

Kai,<BR>Man, siu boon, how do you know I got a scooby? Mark told you? <IMG SRC="http://www.swedespeed.com/ubb/biggrin.gif"> Well, I asked Johann if he could make me one is because since he got one that works already, I don't have to go around and ask people if they want to do it.<BR>Johann,<BR>I am thinking about putting a 100% atmosphere valve on the car, so I will need that spot of the turbo completely sealed.
