Re: New E-Force Corvette Blower Kit From Edelbrock
The E-Force kits are nice, but a little pricey. Hopefully they will encourage blower lovers to rethink the intake manifolding of supercharged engines. Unlike E-Force, most blower installs (including Ford's factory stuff) leave a lot of free torque on the table because of grossly inadequate intake runner length.
And the E-Force kits may encourage a little dabbling in VW/Lancia-inspired twincharging . . . ..
Twincharging would work well with "on-demand" alcohol/E-85 auxillary fueling systems.

Also, it's too bad that the E-Force kits don't feature variable-length runners to further expand "torque efficiency."

Re: New E-Force Corvette Blower Kit From Edelbrock
All any forced induction air pump on an Otto-stroke-cycle engine really does is increase air density.
Repeated dyno testing has shown that more-dense air still behaves like air. Thus, resonance tuning of the intake manifold will still affect how much of the now-more-dense air is inducted at any given r.p.m. into the cylinder. For example, a test published by Richard Holdener found that merely changing from a stock "Terminator" Cobra box intake to a 2001 "All Motor" Cobra intake on a centrifugal supercharged 4.6 was worth a whopping 70+ lbs/ft of torque at certain points in the curve.
The E-Force's extra runner length simply helps the engine make use of virtually-free resonance frequency energy to aid in cylinder filling efficiency. It's the same thing the Ramchargers were doing in 1960, only with a Roots blower added in to increase air density. On a boost-limited, high-compression stock block engine, this is a safe way to increase in-cylinder charge density without adding more detonation-triggering extra heat.
Of course significant is in the eye of the beholder. To some, a 1-5% increase in torque at certain points in the curve isn't worth the extra complexity, cost, or other tradeoffs. To others, it's worth its weight in victories and bragging rights.
