anyone have an open dump on the rb20?

[PorkChopExpress]

going to be doing some upgrading and thought of doing an open dump, mostly out of lazyness .but bet it sounds like garbage. any input?

oh and carl H, if you read this can u mail me. my ecu refuses to follow my programing so i was thinkin of buying a tune off you and loading it into nistune. see if that works.

open dump???explain??

[PorkChopExpress]

oops, i guess that can be vague, just routing the exhaust from the wastegate to the ground instead of back into the exhaust system.

sound on, v8 awesome ----------v6 great----------I4 should get that exhaust leak fixed.----------I6 overstrung I4.

I have it on my RB25, its loud, but not retarded annoying or anything...i'll see if I can find a vid of me "cruising" and let you hear it.

youtube is full with screamer pipe RBs

I have one, and it sounds amazing, and does its job of well of preventing boost creep. Im considering routing it out of my origin fender

rb 20 with 44mm tial wastegate on mine....oo mannn does it sound better then anything i cud evwer imagen

[DRFERO]

well venting the internal wastegate to atmosphere wil give u no better performance.no better boost control..it wont help with boost creep...itl sound a bit ugly and quite too...the real way to go is external wastegate.then u get better boost control and no boost creep and it sounds s*** loads better than an internal screamer

oh and my rb20det runs a 38mm tial wastegate with a screamer pipe about as long as the computer mouse (very loud)

i hate external waste gates that are vented to atmosphere.cool for about 2 weeks then you begin to hate life.my buddy had an amperformance elbow on his car with external screamer, sounded awesome but got annoying after a while since the stock turbo spools so quickly and navigating trafic made life somewhat miserable.on my hks manifold recircing the wg not only made the car nice and quiet but also fixed the horrible boost spike issues that i was having.poor manifold design there.
