Full race gt35r twin scroll

hi lads , u guys been testing them for a few weeks now, good early spool up but did u guys suffer high rev restrictions and powerloss the benefit it has low down it loses up in the high revs

did any of u guys change tae a bigger divided housing

any info will be appreciated, one of my friends a fellow trader fitted one on a customers evo and it got dyno'd today, any info will be appreciated

cheers

How good of a job does an engine dyno do of replicating real life load on the motor?

Is it safe to say that the spool #'s will be consistant to what they would be in the car?

best email norris designs my friend for the full info, it woz mapped on his dyno and run in , i tried getting mair info today he woz out mapping

same spec on an open scroll in his dyno makes over 50 bhp at high revs etc , i woz asking just in case any of u guys have fitted a bigger housing and whit kind of power it made etc, see its the first twin scroll gt35r tae be tested in the uk, i know u guys been running it for weeks now across the ocean and see if u guys suffered the same kind of probs on a stroker engine

cheers

What A/R housing is this on?

Boost is dropping pretty hard and going to a larger housing may be all it needs to come to life up top.

WOZ, MAIR?

Seriously?

You scotts are out of control, and horrific behind a keyboard.

Going from an open scroll to twin scroll you can count on being able to almost double A/R in terms of open to twin scroll changes and keep similar characteristics.

If your worried about top end power open up the exhaust side as much as you dare.

Ah, yes your car will not make anywhere near 350 ft lbs of tq at that RPM at 4-4500 maybe, if its spooling well. My 2.3 Cast (better for spool) manifold, .63 A/R hotisde single scroll 35R makes 350 ft lbs at 4800 rpm, 3k would be insane, that cannot be correct. Thats better than stock turbo territory i believe.

the boost plot shows 21psi @3K. There's got to be some kind of weird loading with an engine dyno?

holy spool batman..

dude, those graphs look amazing for a 35r. I really need to see some stuff to back this up done on this side of the pond. I'd give up some topend for that.
