Official Richard Holdener who wants to buy an intake manifold list

Since it never made any less power than the stock manifold, I don't understand why someone wouldn't be interested in having these gains. If it is a money issue-I fully understand, but since gains came as low as 2500 rpm, that is pretty usable. Even the extra torque at 3500 rpm and 4000 rpm (6-8 lbs ft.) are usable in every day driving.

I believe WolfWings was referring to the fact that the "midrange manifold" prototype showed higher low- and mid-range gains than the latest model. Judging from the above dyno graph, I'm thinking the gains at 2500RPM and 3500RPM should be barely noticeable under normal driving conditions, and that the really juicy stuff should kick in at 4K+ RPM, which is a territory that a lot of "point A to point B" folks don't usually tread under.

Again, I still consider this a worthwhile purchase, but I think more gains at the low- and mid-range would've been even better for people that spend most of their time in the street (i.e. between red lights, traffic, etc).
