6-Port Power

240+ WHp is very good, What type of dyno is that on?

Did they run the stock Intake manifold?

Did you have the stock intake manifold on the 182 WHp engine?

I think I can break 200 WHp with a 6-port, but I would have to rev to about 8200-8500 rpm to do it. I can't get any torque out of them because of the terribly late intake port closing. To make power at 8500 rpm, the first thing I need to do is fix my ignition issue. Maybe next year I will get an E8. (It is amazing that this year is almost over).

The only way to get 200+ WHp that I can see is with a ported stock LIM and a custom UIM. I am thinking that I can cut the flange off an S4 6-port UIM and weld some short runners going to a custom plenum to that.

I see promise in the LIM design. I can't see how I could ever get enough air to make 240+ WHp through that terrible UIM (S4 is a little easier to port than S5, but still nearly impossible).

How does a dyno dynamics Dyno compare to a Mustang Dyno? The dyno right near my house is a Mustang, so that is where I would be getting the numbers.
