Who goes to that much work to only change manifolds, and have data to back it up? I can only think of one person so far. I seriously doubt you will get clear additional feedback beyond dillehay's test results until we do more manifold specific testing.
I've spent all week trying to gather feedback to try and get a clear picture of what is going on. Some customers have fantastic results and some have just a good result but not really huge gains that they can feel, more lowered egts and better fuel mileage. Mikes truck managed to lose power yet others feel a huge improvement in throttle response. It seems to me that the VGT turbos have a big say in what is going on and also I have noticed that the guys having good results are not using wastegates. I'm going to rely more on feedback on non vgt trucks to gauge the effectiveness of the manifolds themselves. I'm also making some different designs this weekend to see if they change anything.

I wish the results had gone the other way. That being said , I think focusing on the non-vgt will put the emphasis on the minority in a huge way. I love your manifolds but in this case they just didn't work. I think if you and Tadd take the time together I think positive results will come. You have the ability to do anything , so I think with a bit of problem solving it will happen , as quality is not In question. Thanks for everything , hope we get a solution.

Not saying I would ignore that market. Just want a test which just evaluates the manifolds with a simple turbo. For that matter, is anyone running them with a big single?
I bet we are a couple of months from knowing anything.
i think leen is starting with the single crowd, to get the manifold more dialed into the motor, then will take that and apply to the vgt crowd.
thats what i got from his "simple turbo" comment.
start simple and get complex.
