Why get a different pump? Without the extra air of a turbo, the stock pump should be more than capable of giving it all the fuel it can handle.
I really want to see how much I can wring out of my N/A vanagon. Turbo for me means a lot more than just slapping a spinner on there and I just can't afford all of the upgrades needed to do it well. So I'm upgrading the breathing on the n/a while I save up for a performance diesel IP.I already got a dual downpipe exhaust for it and changed to an external cone air filter. Now I'm looking at the intake manifold.Calculations for optimal runner length for each intake tract (placing 2nd 3rd and 4th harmonics into the 2000-4800 rpm range) comes out to 33 inches! do you think it would work to use braided stainless hoses instead of hard tubing for this app? If I did, I could run them up into the D pillar, terminate into a box with velocity stacks and have a nice big cone filter there for them. I know it sounds goofy, but do you think it would work, or make a difference?IIRC 2nd harmonic +10%, 3rd harmonic +7%, 4th harmonic +4%I know this is no VNT build, but thanks for looking.

16 1/2 inches sounds about right. probably really close to the same length of the runners on the stock manifold.
I'm pretty sure they dropped the max rpm and max hp on the diesel vanagon specifically to increase low-end torque. The max HP rating was dropped from 52HP to 48hp in the vanagon. I imagine that part of that was specifically resizing the runner lengths for lower rpm torque.

So your saying they dropped the 1.6 to 48hp? I bet they were good drag racers haha, 0-60......hopefully!!!!
