ok so my buddy asked me this and got me thinking. what would happen if you tried to run an undivided turbo with a divided manifold? I'm not really sure what would be the effects of this...
Good question. I run the FP exhaust manifold which has probably the best merging of runners to minimize exhaust pulse interference. Technically the runners are nearly completely divided up to the collector. Functionally its similar to an EVO 8-9 exhaust manifold. There are gains in power doing it, but without the divided turbine housing, your not getting the spool gains necessary to upsize the turbine housing A/R for even more flow.
who's going to be a test dummy. sounds like an interesting idea.
The divided manifold is called a twin scroll manifold specifically made for a twin scroll turbo. IMO it'd be a waste of money if you were going to use this on a single scroll turbo. The back pressure from the cylinder that's in its exhaust stroke would still interfere with the cylinder that JUST finished its exhaust stroke.
