My son has an FD with a normal street port...and we got 480 at 15psi. Water meth though.....but basically a stock FD fuel system pushed to the max
I think the flow of my turbo is a lot higher than yours...
I can run a chart at about 8psi...likely about the same flow as yours at 14 give or take

Reliability and don't really need the power. The 1/2 is a good compromise. It keeps the power band a bit lower and more torque down low and still flows enough up top....and the seals seem to stay healthy longer
Sons is a stock BW366...mine is a 366 with a billet compressor wheel that has been modified and a modified turbine
Might go IWG 9180 and give it a try...but hard to justify the extra 2K for the turbo really

Not going to even try comparing to your setup

I suppose you would be cleaning the ssv very often with a bridge on the secondaries.

You're back !!!! We missed ya !
I actually think it will make a big difference mid range and to a lesser degree at the top end . It works great on an REW turbo . Can't see why it wouldn't work just as well on a Renesis .
What do you know that might change my mind on that ?

Hybrid Greddy Boosted
It's so tight down there that you probably wouldn't get away with a single manifold design that would fit multiple brands/models of turbo. E.g. no way an EFR would fit on that manifold. You'd have to get a turbo that has very similar dimensions to the one that the manifold was built for.
I've heard from several sources that the main performance benefit of twin scroll is for engines with intake/exhaust port overlap, which isn't the case on an MSP unless a serious porting job has been done. So with a standard MSP, a single scroll will likely perform in a similar way to a twin scroll, with probably a little less spool and a little more top end. Brett, is this also your conclusion? If you're moving to a bridge port with some overlap, you may get better performance sticking with a twin scroll setup.
So if single and twin scroll setups on a standard MSP motor perform in a similar way, then the rx8performance manifold would perform at a similar level as Brett's current setup. When comparing these manifolds with a regular Greddy setup, the main improvement in performance comes from moving from a T25 to a T3 turbine housing. I found out first hand that changing from a 71mm wheel (e.g. GT3571) to a 76mm wheel (e.g. GTX3576) made minimal performance gains as on my Greddy setup. It's totally choked up from the T25 and iWG.

There really is no use in having a twin scroll turbine housing with the renesis. there can't be a true twin scroll setup. Having a twin scroll means separating exhaust pulses. Easy to do with older style 13b engines. The middle exhaust port is shared between both rotors on the renesis.

.
Agree re the bridgeport .... should get better spoolup plus better midrange due to the improved VE plus the twin scroll will work better .
That kit comes with a 6266 with a 0.83 turbine housing which in theory should spool about the same as my 3582 with a 1.01 , but mine spools quicker than either of the rx8perf. setups I've tuned.
