ROTFLMAO :D

Surely a wind up? ;)

You've already got one!

@Harrymonk, usual stuff, potential for damaging the maf, causes overfuel momentarily which will give you pops and bangs out the back when you lift off as the ecu will be measuring the air flow going in and putting in the correct fuelling, of course since the air will be vented before going through the recirc and back it'll go rich.

no good reason to fit one other than for the sound, then you run the risks.

Loads of people have no problem at all with them, a handful of people have attributed failures to them. So basically your call ;0

You know you want that turbosmart one you saw on the black motor at Japshow!

BTW, you had any luck sorting out the videos of my runs at the pod?

As said previously, turbo cars have some sort of dumpvalve already fitted as standard. I understand that the one on my WRX MY01 bugeye is a recirculating type, which is best for performance. The other sort (venting type dumpvalve?) is less good from a performance point of view but good if you want the woosh noise. You can get various types of venting ones, some of which you can adjust to change the woosh volume. Hope this helps - but do feel free to wade and crush me with your "whats all this @$***&$£* pmarch!!"
