Thanks guys. Here's a new pic from yesterday. Just finishing up the runners before the wastegate design gets finalized:

It does not look like equal length based on pictures. Any information on the diameter of the pipe? I am curious to what the ID is where each bank combines into 1. Looks a littler on the restrictive side, but I could be way off.

I just find it funny.. that it wasn't until Team Vishnu started posting progress on their single turbo that HPF decided to all-of-a-sudden have progress after HOW many years... smh
If i wanted to upgrade to a single i'd probably go team vishnu's route when it's available. As i probably won't need to find gold laying on the side of a river in narnia under a starry night with a pixie fairy leading the way for me in order to purchase the kit -__- .

I think that is just the angle of the picture throwing you off. However, it might be the closest thing to equal length we've seen for this platform compared to other prototypes? Maybe....

But having a turbo header that avoids very uneven runner length keeps one cylinder from running other than the rest. Almost always, its the cylinder with the shortest runner length that runs extra hot. In the case of many log style manifolds, one cylinder has a super short runner of only a few inches. Which is undesirable due to this behavior. This is why we opted for a more labor intensive, but more optimal design, that keeps the min runner length reasonably long. And offers smooth, low angle merges at every transition point. This will result in good spool-up/turbo response compared to a conventional log style manifold. The ID of the main collector is approx the same diameter of the turbine housing inlet which is also desirable. -shiv |

That looks great. Why is it that you don't just use the N55 design for the single turbo option? Doesn't that manifold just bolt on?

For one, the runners are far to skinny to support big power. That alone took it out of the running.

But one thing is for sure. HPF will have the biggest power output and highest quality kit. HPF just does things correct. |
