I don't know. It's something that we can't seem to effectively measure.

 

I will make a couple different extensions then and log each one.

 

This is incorrect. We do not incorporate a DNP manifold in our kits. ONE customer brought a manifold by for us to build him a kit utilizing the DNP T4 TS manifold they produce. With that said, we mentioned in that thread that we were impressed with the construction and flow characteristics of the manifold. It worked very well and incorporated only ONE gate. We build our own manifolds that also incorporate One gate. We haven't found any quicker response from utilizing one or two forms of gate.
What we have found however is that some setups require two gates for better boost control and space for proper gate entry and exhaust.

 

The first kit you guys put together did, for testing.

 

When "true" twinscroll design is mentioned, does that mean that on an inline four cylinder engine, the manifold has no common collector and that there are two divorced, pairs of runners turbine housing exclusively, while the remaining two runners feed exhaust gases into the other half of the housing?

 

Yes, exactly.
