Alright i understand the engineering and air flow principles to a blow off valve, but i've been told that they're good by some people, and not necessary on our cars by others.<P>If anybody out there really knows (I haven't been on IM recently) please let me know, i'm interested to hear why our cars don't need one. I have a feeling it has to do with our internal bypass valve, but i'm not sure AT ALL.<P>Also, so many other tuned cars out there get aftermarket intercoolers, i understand that philosophy as well, but is it just too much money for too little gain, or is the stock intercooler just fine, only re route the piping/???????<P>Thanks, <P>

David,<BR>Go to the FAQ section of <A HREF="http://www.T5UK.com," TARGET=_blank>www.T5UK.com,</A> it gives full explanation of bypass and BOV's there plus which is best !<P>

So...is the car going to run lean or rich at the end? I'm not sure about the Suck-In-Valve aspect of it, but...if that's the way it is...wouldn't you think it would blow off more air than sucking at that 'instance?' <P>Hehee...I guess I'll go talk with few more 700hp turbocharged cars owners before I make any more comment. <IMG SRC="http://www.swedespeed.com/ubb/wink.gif">

overall the car will run slightly on the rich side. As power goes up to the 700bhp limit then a BOV is better in that it gets rid of the excess boost faster but I don't know of any Volvo getting anywhere near that figure.<BR>Each individual application has to be taken on its merrits and the recirc. valve on the Volvo is perfectly good and the only time I would consider replacing it is if it fails and I know Volvo UK do not sell this part seperately so a recon. Turbo would be required.<BR>Incidently I love the sound BOV's make and this can be considered a reason for fitting one!<P>

Further to the above it also depends on where the MAF is located in the intake system !!<P>This is just for Kai (who loves a good healthy discussion!)<BR>It must also be remembered that everyone has different ideas on tuning and this is how we make progress- it would be boring if we were all the same !<P>

Fraser,<P>I think that is your site, right? If it is, that's a great site, you have some really important under the FAQ's section. Good site!<P>
