well i got a twin scroll 30r and im seeing 24psi at 3900 rpm. my logs show this.... i have big cams and a stock ecu as well. just my info.

 

Yea...I was wondering how they have the cyliners paired on the TS Manifold....didnt see twin gates in that setup

 

I be really interested in seeing the difference in spool up too as a big thing about the twinscrolls is turbo response...

 

Maybe you need a new recipe for your pudding

 

I have a standard 35r and see 24psi at 4500 in second gear. Your twin scroll isn't much better if at all.

 

in second lol... how about what everyone tunes and dyno's in ? 3rd or 4th ? and are you running meth ? are you stroked ?

 

also this test dose not say it used a twinscroll manifold. twin waste gates. so this test really means nothing in a real twin scroll vs reg setup.

changing just the hotsides was only a waste of the guy who did the swaps time. come on ams you should know better then that.

 

o yea. in my 2nd gear i see 24psi at 2100rpm. cant touch this. hahaha

 

+1

 

Bull****.

Scorke

 

Tim's Evolander has a properly designed twin scroll manifold with two wastegates on it. Look at the vacuum lines and you can see the T's in them for the two WGs.

Just getting rid of the restrictive divided housing gained power up top and spooled almost the same.

Think about this for a second. You can only push so much exhaust through an open T3 flange before it starts becoming a restriction. Now see how much exhaust you can push through a divided T3 flange.

When you are shooting for HP, the twin scroll has the disadvantage.

 

I'm still curious about turbo response time...you don't use a twinscroll to drag race, you use it for the track...

 

Please post some pics of the Twin Scroll maniold used.


Also what kinda difference would a .85 A/R have with a .68A/R?

I would also like to hear how Full Race feels about this.

 

what gear/load conditions?

 

Im pretty sure we spool just about the same or a little sooner on our open scroll 30R kits on a 2.0 in 4th gear.
