Brainstorming Manifold Ideas

[guitaraholic]

After a bit of research, on manifolds, I've found that the stock manifold ported (honed) out is best for those who plan on using the stock T25/T28 setup. I am guessing that a LOG style is good for low end, and an equal length will give you a bit more top end, at the cost of some a slightly delayed spool. Here is what I am thinking. What if you...............


Use an equal length manifold and use a 2-3" tube (maybe longer) that separates the manifold from the turbo, this would allow time for the exhaust impulses to "merge" together and you don't get the side to side interference that is only overcome with a twin scroll. If it works as planned, you could get some awesome spool (like almost that of a twin scroll) without the cost, and you would get some awesome spool time and upper end with something like a gt2871r.

I've also am thinking about going with an external WG setup, because you don't get the back pressure at high RPM that causes you to loose boost near redline
