[Supras] blowoff valve recommendation

[berniek at technicaldevelop.com]

For the last two weeks I've been getting my jollies by driving my '91 
with 550cc injectors, 57 trim turbo, Walbro, Lexus, 3" exhaust from 
turbo back, etc.  However, a disturbing boing-oing-oing sound has 
persisted from the air intake when closing the throttle under 15 PSI 
boost.  Spoke to James at Performance Techniques about this, and he says 
it is compressor surge, which I suspected.  From all I have read, using 
the Bosch Porsche right angle blowoff valve should have been sufficient, 
but it is not.  I get the sound even at low boost. 


So I'm looking for recommendations as to which BOV to use.  I would like 
to recirculate to the accordion hose, even if I need to cut a hole in it 
and use curved, clamped large washer-like pieces on the inside and 
outside to provide a large bung for the BOV discharge.


Any and all suggestions would be appreciated.  Thanks.


BernieK.  PS:  Arlene and others were right.  There is never enough 
power even if you can "walk" the tires in second gear.  Starting to 
wonder what to do next for more HP.
