explicitone - I was referring to his setup, not yours. Your PI lower intake has revisions that help it flow more air at higher rpm as compared to his NPI intake. So when you open upper intake up on a PI, the engine gets the extra air because the lower flows equally as well.
The NPI intake is really bad...it's worse internally than it looks. Tiny port cross-section really kills airflow at ~4500 rpm. So even if his upper can flow more, the lower is still a choking point. Anyone that has put a set of ported heads on with the stock NPI intake has learned that the HP curve goes flat at ~4200-4500rpm. The lower intake kills [/URL]

I see your point I misunderstood your post

I am just sick of people bashing mods that they dont have and have never used just because so and so said its no worth it so then they start spreading things they know nothing about
