Idea...may be dumb
Ok so Im thinking....everyone says that boosted manual cars dont perform as well as automatic boosted cars because you lose boost through your blow off valve while shifting and you have to get it going again.....so in my case with an STS setup....
My thoughts, and Im sure someone has thought of this already, are to pipe your blowoff valve into the exhaust that feeds the turbos so that they tend to stay boosted or at least spinning more than if you vented it to the atmosphere. Seems to me that would just recirculate the boost pressure until the throttle blade opens and....well I think most will get the picture.
Anyone ever done this on an STS?

I've read about this on other Turbo forums!
It's very similar to the INTERNAL wastegate, it is plumbed right back into the exhaust - try a GOOGLE search and see what comes up
Thanks,Matt

Wouldn't exhaust pressure be greater than boost pressure(for most people)? If so then wouldn't you end up pushing exhaust into your intake instead of intake into your exhaust.
Just a thought it's, late and I had a couple of drinks.

My car.....oh my car.....well it does have a little stroker 402, hardened diff, built mn6, dte brace, pfadt motor mounts, cnc'd heads, roller rockers, hardened pushrods, ported fast 90, ls7 tb, twin disk clutch and aluminum flywheel......and yes its been since last September since this thing was dropped off but things have gone crazy and it wont hold a tune or something of that nature....been told by another person that the pcm grounds may be jacked up. So to answer your question about how my car is doing....I dunno.
