another problem with using them on a non-boosted vehicle is that the passages are no longer trapered like they are stock. This might decrease velocity a little bit in a normally aspirated motor.
I did not bother to port the heads, maybe later. But it still made a pretty decent gain, granted I would get even more if I had port matched everything.

Also you are forcing the air past this ridge. Not pulling the air over it. Subtle but noticable difference in flow dynamics.

The cost for boring out the lower intake is $60. Installing bigger butterflies would be too much of a PITA so all he is doing is boring them out. I guess if you are interested you can email him at: hpdyno@aol.com

The stock one is still in one peice. I used an old SE manifold to gut incase it did not have positive results.
I'd like top keep it in one peice in case I want to return to stock.
Sorry

Do you think that the 'breathability' you gain from having no rods/butterfly's in the airstream is worth the low-end torque you are losing? The blower can't be generating near enough boost down low to compensate for their loss, and maybe it even makes it worse having the blower on it. Why don't you consider reboring the secondaries with bigger butterfly's so you can have the best of both worlds?

When I had my SE SC'ed and pinned secondaries, there was no loss down low at all...
