I got 1 PSIG more boost, and 35 hp on the bottom end, below 2500 rpm. at the top I got 7 hp overall but the bottom end really carries the car faster off the line and it makes a big difference. The restriction in a single filter and 3" pipe was 30" of water at WOT or the 1 psig.

I've been trying to tell forum members the advantages of a 3" dual intake for some time. Glad you discovered it.

Now, just imagine if you had two huge, less restrictive air-filters and took advantage of ram-air the intake openings provide and your tubes weren't so darn hot.

If you enjoy the added HP at the bottom end now, wait tell you get that 185mm installed.... you'll get 10-15 more HP at the bottom and 20-25 more at the top.

Then a tune.

Enjoy....
