Finally got around to posting my dyno sheet.

S4 TII, 3" Racing Beat turbo back, Rtek 1.5, Blitz BOV, 8mm Accel spark wires, Walbro 255, stock intake w/ K&N air filter. Slightly ported wastegate, still creeps. About 9-11 psi.

 

looks like you let off early, should have taken that sucka to 7500. anywho, those are good numbers on a mustang dyno. how do you like that RB exhaust? sound pretty good?

 

I wasn't "driving". He asked how high I wanted the RPMs, I said redline, not past (About 6500.) Kind of playing it safe I guess. I couldn't even watch him push it that high/hard.
I love the exhaust. Sounds great. Nice tone, not too loud, flows great.

 

looks about right for an s4 TII

 

im still debating a turbo back, a muffler costs $203 from RB and you have to buy 2 thats $406 right there and the turbo back is $595, but then you have to either buy a FCD or an Rtek with the turbo back. and im still debating what to do. how much porting did you do on the WG anyway?

 

Almost to the edge of the stock flapper. Still creeps. I'm going to port it bigger soon. When I get a chance.

 

how loud would you say the turbo back is on a scale of 1-10, at idle, and at WOT, 1-being silent 10- being obnoxiously loud

 

Idle I would say 2, a little louder than stock. WOT... around 7 maybe. I don't fear being pulled over for loud exhaust.

Not like my S4 N/A, damn thing sounds like bees in a can.
