That's the intake that I run on my 540. Ken at Indy had told me that in my street/strip application that I would like the dual plane better than the single. Coming from wedges, honestly, I doubted him. So, I bought both Dominator flanged open and dual plane intakes and ran them back to back on the dyno during break-in. The Vanke dual plane gave up 11hp at the top while picking up nearly 30#lb of torque.

The engine peaks at 6,800 and made 685hp with a 1050.
