Quote, originally posted by Don R » Reason why ABD has made satisfactory results is do to its short, wide and stuby runner design. I'd like to point out that it's overall performance would not be as expected.
Trq in the mid-range would suffer and fuel atomization would be less than opitmal as a result from low port velocity and turbulent flow.
So what we need now is for people who have purchased these manifolds to run a few before and after dynos for comparison.
As far as the length goes Don if your willing? I read slappy saying that if all you wanted was great flow you would just bolt a plenum to the head? this would equal great flow with no velocity. Now, for my application I believe I could use some sorter runners to help horsepower from 5K-8K and also change the torque band upward.
What would be an ideal length for the runners based on the powerband goals? My home brewing logic says bust out the saz-all and cut 2 inchs out of the middle welder back up and let'r eat, but i thought I'd ask before I turn a decent success into a complete failure.
