Divided vs undivided
Does a divided manifold coupled with a divided turbine housing make a difference? this is for an Inline 6 motor I notice divided housings come with bigger a/r's
with a gt35 would a divided mani with divided housing .70 a/r turbine, spool faster or slower than a non divided gt35 manifold and turbo with a .58 a/r? and would transient response be any different?

Re: Divided vs undivided
It would make a difference if you have a manifold made for a divided turbo. and on a 6 cylinder i would use a bigger a/r than that like a 1.00 or so

It makes a difference, reported faster spool and more topend granted you dont go colossal on the A/R. It pairs the exhaust pulses down low for faster spool and allows better breathing up top.
I didnt do the math, but I am pretty sure a .58 AR undivided is acutally bigger or close to it than a .70 divided but I could be wrong.

Re: Divided vs undivided
You dont' want an divided .70ar on a gt35r. Pretty much the only available divided housing for a gt35r is a t4 1.06ar divided. It seems big but we are running one on our Mitsubishi Evolution X and see 20psi by 4250rpms. I think with the better tuning options availabe for the honda market you would see it even soon on a 2.0L.
