I got these definitions online, from, Eric Fahlgren's, "TURBO GLOSSARY".

Boost Creep: Occurs when the wastegate/turbocharger combination is improperly sized and cannot dump enough exhaust gases. The symptom is rising boost as RPM's rise...To reduce this effect, either install a larger capacity wastegate or a turbine housing with a higher A/R ratio.

Boost Taper: A phomenon produced by flawed boost controllers, which causes boost to drop(or taper off) when it should remain steady.

 

Funny how when I threw my custom 02 dump up for sale it took months to sell and I practically gave it away! But how I miss being louder than a harley!!

 

Yeah, you can just use that flexable tubing. I used that to run the wastegate out my bumper on my Mirage. Works great

 

has anyone tried merging the dump tube into the down pipe further downstream? back to the cat/testpipe. quieter and less turbulent. i suppose packaging could be a problem.

 

Yeah, if I recall, Soon2BEVO says that merging is a b*tch plumbingwise.

 

found this.

looks like an improvement over stock. but what are the draw backs

 

That looks sweet. I wonder if you'll bolt to other aftermarket exhaust/testpipes/cats.

 

i just did it on my buschur manifold
i have the old buschur br500bb which uses a cheap internal gate.
so i just welded a tial 44mm on then and am running a open dump tube
works great for me. no boost creep no boot taper. but i am runing a 30r
