DynoSim

K, I have a dynoSim 2000, desktop dyno. I generaly use .050 lift figures for the cam and dual plane standard flow on the induction menu. For the 400, when using the edl performer manifold, should I use the standard flow or high flow manifold model? Does anyone know what would give the most accurate result? Same with the cam specs, what gives a more real world reading, adv duration or .050?

well I'm assuming, the high flow would be like an edl performer RPM with spacers, and the standard flow being the normal edl performer manifold for the 400. I just don't know how accurate this is tho.

I doubt it is accurate at all. Have you looked at the head flow info? I had to manually enter the flow info as their head choices were way off.

oh, yeah. every detail it allows me to fill out. Head flow to comp calc. I have heard that they are fairly accurate if all the right info is added. I even cross reference with a DCR calc, to run different deck heights, piston relief and chamber volumes. Just to make sure it would actually run on pump gas, with what parts combo's etc.

That's my point - the calc's are accurate but the flow rates of items in their database aren't. So you have to manually enter them.

yeah, I do that for EVERYTHING. Also, as an example my early72 400 heads have 75.6cc chambers. D1AE-A1C. As for head flow numbers, I've entered 4V, 2V, 2V Powerheads ported, TFS powerports etc etc etc. Since I'm stuck with fairly basic manifold induction choices(not being able to model intakes on this dyno program) is why I ask if anybody knew from real life exp, if these came close to actual dyno'd engine combos. That's all. I did read the instructions too. I'm funny that way.
