FWIW
I was just looking at the Banks ad in issue 35 for their brake. I'm not sure I can swallow the hype. If this brake adds "15 or more hp" because the butterfly is 8" downstream then my 4" downpipe and remote 4" BD brake must add about 50hp.
Are they saying that waste gate flow restriction on the butterfly can caues power loss? Are they saying that the swirling exhaust gas stops swirling after traveling an additional 8" down the pipe? Looks like it, according to their cool drawings. Wow, I didn't know there was enough boundry layer drag in the pipe to stop the swirl in 8".
My thinking is that Banks is doing a really good job of marketing a questionable theory. I am sure impressed with their adds. Big, high quality, expensive and lots of them. Top quality materials and lots of extra do-dads in their packaging too. Prices are nice and high to provide fat margins. I wonder who pays for all that? Could it be the customer paying a higher price for a product that does the same thing as less expensive competing items.
JMO
Banks! Impressively run business, not so impressive products.
