Has anybody done a back to back test with their ported 4 piston skunk2 ultra? Any gains? They look great just looking for some feedback.

I just had mine done but I couldn't give any back to back comparisons as I've changed a lot of my setup and the data wouldn't be accurate but their claiming really nice gains on boosted applications. They shape the ports to match the head your running too instead of it just being a universal opening IE if your running gsr head it's shaped the rubber opening to utilized the high port design.

I am running it on my build but have nothing to compare it to. 4 piston claims the port work is worth 8% gains over a box stock ultra series. I can't wait to dyno tune and hit the track.

Just to clarify, that is not across the board. We have had tests come back at 7-8% on large turbo applications. We have seen mixed results on all motor applications. Some have had significant gains. There have been some cases where the manifold was too big for the engine and it lost power in low and midrange rpm. For instance...put a 5.5L Ultra on a 1.8L 12.5:1 motor with small cams...its gonna die. For small B series engines, the ported Ultra Street fits much better.

If you guys want some real world feedback, watch the Speedfactory cars on their east coast swing this fall. They gained significantly in their back to back. Ramey also went from non ported to ported and gained mph. I'm sure those guys would be happy to talk about it at the track.
