We have other ideas on what to try if it doesn't make power, but hopefully this is all hypothetical and she does great . We can look into this but there really is a lot of thought and time that goes into producing parts similar to these. I'm not just talking Velox parts, I'm talking about a lot of aftermarket products out there. To do it right, it's more difficult then a lot of people think. We'll look into it though. |

Ferrari Type 049 Renault F1 [ame="https://www.youtube.com/watch?v=y2iBbwocYZw"]Renault F1 Engine - YouTube[/ame] All the V8 & V10 NA F1 cars used this style of FI. I'm sure @eric6 can attest that it is a better design, but he has already commented on why they chose to omit that option; and, their reasoning is very sound.

It sounds like you are virtually blowing air through the manifold and making sure each runner gets the same amount. What you should be doing is blocking off 3 runners where they would meet the head and then suck air through the one you are testing and measure the flow. Then repeat for the other three and compare. This is how physical static flow testing is done, CFD should probably be done the same way.

Sucking air though is not that inaccurate. It just needs to be done and analyzed properly. If the manifold can flow more air, maintain or increase velocity, and ensure each runner draws equally, all through static tests, we know it will be better for pure flow dynamically, too. But blowing air through can give you completely wrong data, even statically. Where the real problems of non-dynamic testing comes from is resonance and wave action stuff which create very timing critical pressure changes which can affect flow. Runner length and plenum volume is about controlling and optimization of wave action.

@Dimman, we definitely sucked the air through, no blowing.
I told myself I wasn't going to post anymore of the intake manifold until it was finished but I can't help myself. This is sexy... |

@NotEric6
I think your next project should be a highly transparent hood so people can see the intake as they walk by.
