I would like to people to post their experiences with T4 twin scroll turbo setups on the Evo x. Both good and bad please explain.

some chad guy at CBRD (decent shop) uses open scroll for less back pressure

"And another point- our 7163 is OPEN scroll- not twin- which inherently tends to have less back pressure and lend to better peak power- so that lends to the balance in spool versus power output also. "

Maybe this help maybe it doesn't, good luck finding the right setup for you!

I'm leaning more toward twin scroll based on street driven characteristics. Im looking for more info on 1.6-1.15 A/r turbine housing I think this will give the same top end as a undivided t3 .82 A/r but faster spool. I could be wrong. turbo im using is a t4 divided pte dbb 6262

its usually a matter of housing selections versus turbo size/power output-

its hard to get the perfect combo for a twinscroll to work properly

what type of power output are you looking for?

Right now I'm wanting anywhere from 550-600AWHP. I also have Kelford 214Cs waiting to be installed. eventually I will shooting for 800AWHP and with a efr 9180. in the mean time the 6262 will be installed.

For a turbo that big.. I'd definitely go with twin scroll.

This was low timing and knock free as verified with the initial start of the Q16 tune. Because of a miscommunication the WG had been plumbed side port only so I stopped as soon as I was starting fight boost drop. However here is the initial Q16 dyno session on a 35psi spike dropping to 30.8psi.



Hopefully these help!

Thanks,

Michael

How is 800whp a high expectation with a built engine and a 9180.. I would say its pretty easy to reach and has been done plenty of times.
