For a twin scroll top mount manifold I assume it matters which exhaust ports are mated up. If so my question is which ports need to be mated is it (1&4 2&3) Is this correct? Are there other options? Any PICS?

Thanks

 

1&4 together 2&3 yes

 

 

So 1&4 2&3 is the only way to mate it up I take it. Is it the same for a divided manifold as well?

 

in my mind im pretty sure they are the same thing someone correct me if im wrong please

 

So basically a divided manifold could be used for an ordinary turbo as well as a twin scroll turbo? Is this correct....anybody?

 

yes it will be fine

 

Thanks for the info.

 

What's the difference between a twin scroll and a divided manifold?

 

almost all manifolds i seen are 1+4 , 2+3

 

twin scroll = turbocharger.
You can have either one separately, but its best to have them both.

 

OK so what about using a (non divided manifold) with a turbo such as the S366 or S366XL? Is that even possible? If so would it still proform up to its potential?

 

If you use a non-divided manny with a divided turbo you will not see the benefits of a divided setup, my friend did it with a 42R setup and said it will be fine and as soon as he got tuned he was complaining about how unresponsive the setup was, after I preached to him for months not to go that route.

Of course its possible, why wouldnt it work? Its a turbo sitting on a manifold.......

You pair whatever pistons that go up and down with each other, in our case its 1-4 & 2-3..... the whole purpose of a divided setup is to have a constant uninterrupted flow of exhaust gas over the turbine wheel, with an open collector all 4 ports just dump into a common area and then they are forced over the turbine wheel, which has not been an issue for decades, but when you are looking for every little bit of power and effeciency you can get... IMO a divided setup is the way to go.

please dont say twin scroll, nobody offers anything twin scroll for our cars to my knowledge even though some companies market their products as such. I am pretty sure their manifolds will work properly with twin scroll turbo's, but I am pretty sure there is no such thing as a twin scroll manifold unless someone has introduced a divided collector that can vary in size by rpm to match a twin scroll turbine housing.

 

Good info...Thanks. The reason I ask is because I thought I heard somewhere that an S366 can be used on either a divided or non divided manifold. I have a non dividrd manifold and wonder if I would be very disappointed if I used it instead? I could always sale my manifold and get a divided manifold I suppose. Anyone have a good suggestion on who to go with on buying a manifold for a good price?

 

Any divided turbo will work with a non-divided manifold and vice versa, its just pointless to do so. As long as your flanges match (T3 turbo-T3 manny/T4 turbo-T4manny) there is no issue....

Disappointed? What are your goals? Its not like your going to lose 100whp with the mismatch, its just less than ideal and your spool time/transient reponse will suffer.

If you want quality its not going to be cheap, full-race.com IMO makes the best divided stuff I have one and its built with amazing quality.

 

Thanks again. My power goal is 600-700 range, I have the built motor and fuel setup that should support this. As of now I have a SC61 .63 AR with a T3 top mount 3inch DP and I just think this turbo will struggle to meet those needs. Any more suggestions?

 

Order off the Taco Bell fresh menu. That stuff is good eatin!

 

i was under the impression that a divided setup is only good for a street car setup as it givers u better response & spool at lower end power. for a drag car that is not necessary, & the dividers actually take up room making your passages smaller.

i haven't actually tested that fact as far as power wise.

it would be nice to see a test of the exact same turbo with a non divided & divided housing test. would be very easy to do. unless it has been done

 

NO, a divided manifold with a twin scroll turbo makes better power at low and high RPM. This link explains why. I just want to know how much power and response I would be missing out on if I used a non divided manifold with a twin scroll turbo such as S366 or S372??

whats the difference between a divided and a twin scroll turbo?

 

a twin scroll turbo can vary its A/R size (in simple terms) to allow it to spool like a small turbine housing and then open up to run well in the high rpm range without choking the motor up. A divided is just a divided housing.

TS is very popular on low reving Diesel Engines.
