BP4W was an 83.5mm bottom end, stock BP4W head/cams, ABSURDflow manifold/DP, GT2871R 52-trim 0.86a/r, VICS manifold.
VVT was an 84mm bottom end, stock BP6D head/cams, same turbo setup, Blox B18 Honda IM.
Three runs on 100 octane, one run on E85.

Blew up my built BP4W, replaced it with a built BP6D but my first dyno session was without VVT. This was way back in 2010 when MS didn't do VVT and I had to figure out how to make my AEM Series 1 box do it (with Jason and Julian's help).
Good guess. I would attribute about 0% of the low-end bump to the Blox. You can actually see the small dip at 4500rpm where the Blox doesn't work as well as the OEM VICS manifold did. This was before the days of Squaretop popularity so I didn't have one of those to test. The Blox did me no favors on the bottom end, but the VVT more than made up for it.
How much of the low end bump, if any, would you attribute to the Blox? (not familiar with it, though I'd guess its short runners are better for upper revs anyway)

What can I say, I have learned to live by the mt.net bible. Will you all allow one noob question? (It's more of a poll) Research says the VICS manifold out-performs the VTCS manifold even with VTCS deleted. But is it worth paying for a complete VICS manifold and ditching the VTCS manifold I already have? Or is it just a "yeah I definitely felt a difference bro" modification? And is $100 a steal for a complete VICS manifold?
Thanks
