Hi,

I would like to know if somebody runs a big single turbo with the high performance RB turboback? I'm talking about a FC. Does that thing flow enough?

Thanks!

 

oh god yeah. just the exhaust alone will eliminate backflow and lt u boodst right upto 10psi, with a 60hp gain! the sound on it PERFECT aswell.
worked great with S4,S5 ans hybrid TO4 turbo

 

If you do get a free-flowing exhaust, you're going to want a FCD as well.

 

Ok, but I'm putting a full T4, not just an hybrid. And I don't need a fcd, I'm running a standalone.

 

Standalone...that'll do!

 

I am running T66 half bridge with the RB turbo back. Keeps the noise down. I will post again this week after tuning.

What I did was build an adapter from turbine to the RB piece. I would not do this again, as it's a PITA to seal it right and the stock flange is not full 3". I plan on having a 4" downpipe fabbed up instead.

 

it would be possible to to build a custom downpipe with wastegate flange and lead it back to the rest of the RB system. i've seen that done before, but it was a borla system instead.

 

I will probably make a custom downpipe with a vband flange to the RB presilencer.

nik let me know cause I my turbo is similar to yours. But it's not a half-bridge, it's on a ported 13b-re.

 

haha, I was wondering exactly this myself, I'm going to build my own though..

 

Yea the problem is that I have received the RB last friday and it's not the same size as they say on their website. Suite to my email to them, they have modified the text.

 

what isn't the right size?, cuz RB has a habbit of sending N/A cat backs with TII downpipe and prescilencer.

 

I measured the downpipe outlet and the Y pipe inlet.
