| I think your explanation of additional room for headwork clears up some of my apprehension. I don't believe you would intentionally misrepresent anything. I also don't think Jon said anything to that effect either, atleast on the forums. I do believe that it would have been valuable to test the flow capacity of the collector itself rather than add up the individual numbers. I also know that you did what you could and its very much appreciated by everyone concerned including Jon. That being said we still got valuable information. I think both designs are way ahead of the stock manifold and are an improvement by any measure. Further I do NOT think that equal flow thru all runners is a good thing on a log style manifold though because you are flowing #1 into #2 so the #2 has to do double duty of sorts and it needs to flow the most. What the ratio should be between #1, #2,#3 ? I can't say due to the large number of variables. I was not that disapointed by the #3 results. If you have any thoughts on this fire away - i'm interested in your opinion. I have tested EGT's on our test car at the #3 and #1 runners with the V1's and i'd say they were a lot closer than they are on the stock manifolds. What does that prove ? I don't know, except that the back cylinders are not running as hot as they used to. I think THATS a good thing. The V2 design is even better. We tried to address gating in the now still born V3. I do think that V4 will address all the issues from runnerlength, to gating, to collector design and to dp design :). In the end we are all working to design something better for our cars. After having actually got a set of MS manifolds in my hand for a customer i can say that they are a excellent design given the design constraints that he had to deal with. I also like jon's design also because it addresses several issues that affect the stock design. I think if he had made round ports vs oval ports closely matched to the stock heads he would have flowed better. ALTHOUGH personally i think following the contour of the head port is actually better for dynamic flow. Maybe we will test the round port idea in future. I have a set of junk heads that i will have my machineshop section out to see how much actual room we have to transition the head port shape. I would do this for the MS monifold powered car that i am building IF there is room. We have got heads to flow 275 cfm per runner with larger valves. I think it would be better if we could have manifolds that flow atleast that much per runner :) thanks Harry
