I saw a twin turbo 3000GT VR4 that had nothing stock about it this past weekend. I notice there was a BOV on the upper innercooler piping on backwards.. when I asked him what that was for he said that it was because his custom built turbos make boost at idle so that would relieve the extra air pressure.. Is this possible?!

All engines run in vaccuum at idle.

NO

like someone else said

engines run on vacum, and with TB closed theres not enough space for any kinda boost to be built and flow...

i say BSSSSSSSSSSSSSSSSSSSSS

excellent.. that's what i thought but he knew seemed very educated on FI stuff and his car was NUTS. thanks for the input!

maybe you mean making boost off the LINE...but it sure isn't happening on idle..

Id like to see any car try and maintain an idle with 5psi of load.

He probly meant the turbos were spinning at idle, which would move some air, in turn creating some "boost" so to say. I dont think he meant there was positive pressure in the intake manifold while his car was idle...

spike

but would a bov be necessary to bleed off the extra air produced? I can't see how this is possible.

vortech centrifugal (sp?) relieves boost at idle, well at least that's what the bypass valve is doing during idle.
