I'm using pipe max software to help me calculate my header dimensions for a 4" stroked LS2, with hand ported LS3 heads with a cam some where around 236/240 on 112 +1. But Pipe Max requires an estimate of VE to make the calculation. The exhaust will basically be running open collectors, and I'm presuming the ~15 degrees of overlap at 0.050" should be enough to get me over 100% VE. There are quite a few combos out there similar to mine putting down close to 500 whp. That's got to be 575-600 at the crank. Presuming a max rpm of 7000-7200 that's ~110% VE correct?

I'm posting this in the PCM section because I figure a lot of you guys tune your fuel by VE, and I'm wondering what your highest VE cells are?

Thank a ton!

My engine in sig below was right around 102% VE. I'd imagine you'll need more.

depends on your intake, and if it is a restriction. I would guess 98 - 99 actual.
