Bump, interesting as was going to go bigger with my ct sc.

Great thread, anymore info/dynos with bigger exhausts on screen setups?

Last few posts are na so not relevant.

Thanks

 

But the 70RR sounds sooooo good! J's needs to make a 75RR !!!!

 

anyone compared the greddy SE exhaust and the Comptech exhuast with supercharged set up? Which would be more ideal?

 

 

Hmm, i dont think anyone will be able to tell you for sure if you'll gain power going up to a 3" system. Your setup now should be pretty free flowing. I'm on a full 3" straight pipe no resonator setup running 515whp turbo but one major complaint i have about my setup is the terrible resonance at around 3500rpm. It's so bad it makes any loose change in my car rattle like crazy. I can feel the vibration through the seat, steering wheel...not real sure how to address it. Could be the solid rubber motor mounts....could be that i dont have any resonators....could be unequal manifold runner lengths....i donno.
I guess what I'm trying to say is that if your setup sounds good and doesn't have any issues with vibration leave it the way it is. You might run into other issues trying to chase that 10whp.

 

Wow u need a resonator Andy. My hks comes with a resonator. I'm thinking about adding another resonator but don't know which location

 

I'm turbo at 508 with a invidia q300 catback. I also have a 3" exhaust cutout at the end of a 3" downpipe. When I was having it tuned there was no power to be gained by opening the cutout. The only thing it did was get the turbo to spool 500rpm sooner.
