This is some great info!  more please! Has there been any headway as far as 
bypass/blowoff valve installation on UrQs, etc?  Martin?  I know Neuspeed 
offers a nice bypass valve (by HKS, I think).  I'm still smitten with the 
"BB-V-V-V-V-T-T-T!!!!" sound...
                                                Thanks,
                                                Tucker
