Is it more of a making sense money wise thing or a power thing? Believe use said Patrick's added 10-15 without a tune tweak.
If a money thing, why not charge a couple hundred for a tweaked tune that will work with the ie manifold?
How did you guys get that far into development(looked pretty far along) before knowing whether or not it was going to give any gains?
I'm not sure about Patrick. I assume you mean Patrick with the GLI at USP? I don't think he picked up any more power, but he also didn't have the same setup as you. It's more free flowing since the turbo was much larger. I do recall a ported head on his car being removed because it made less power, even with the freer flowing turbo setup.
With the manifold we only wanted to sell it if it made more power than stock, and or possibly if it had other added features / benefits that would make it worth while to sell. I can see that happening with some of the items like extra ports for injectors / water meth but I'm not sure if we'll have support for the injectors / meth. That may be one of those things where people are on their own which would be a break from what we typically do.
We tested the manifold and there simply weren't any gains with it. IIRC it was pretty hard to tell if a run was with it or without it. Since then we've hired new people, one person who has spent the past 20+ years working on improving flow on heads / manifolds and he went back into the project to see what he could gain. He was able to get quite a bit more on the flow bench, but we haven't tested the final product on the car to see if it will make any more gains or not. The bench doesn't always translate to real world gains. It may make more, but then again, it may not. This is similar to the way head porting doesn't always make more gains on every setup, even if it does flow better.
Essentially, the manifold has to be a restriction for it to make more power. Thus far, it's not looking like it is. Ultimately I'll need a little more data to know for sure.
