Twin Scroll turbo on open flange manifold

[OneJSupra]

The question is about the negative and positive affects of using a Turbo with a divided twin scroll exhaust housing with an undivided flange turbo manifold.

Nothing positive about it, unless you really HAVE TO HAVE that turbocharger on your car.

Positive is quicker spool and response if you have a t4 divided housing on a divided manifold.
