[QUOTE="Robert M, post: 16384808, member: 9628"] No, nothing to back up my claims, no dyno numbers, my car has never been on a dyno and I will probably never get it to one. BUT, that being said, if Rick at Kenne Bell says that boost is restriction and I assume restriction is going to reduce performance, then reducing the restriction must increase performance? I lost 1.5 to 2 lbs. of boost (restriction) by going to the 3". <<<Now, that being said, I am now working a deal to replace my Shelby installed 2.8 KB with a 3.2LC, which will then add back boost and additional HP.......I guess with the 3" I can now afford to add back some boost and HP while still staying on plain old 93 octane fuel. I am told that "if" I choose to reuse my 2.8 Super Snake pulley on that 3.2LC, I will be in the 19psi range and need to think about a fuel booster (Torco, etc.) with my 93 octane street fuel. ...................and I don't look at anyone as being "That guy", this mod stuff can cost a lot of money, and no one wants to throw money away for no gain. I am assuming the engine spinning up quicker means that it is more free, which usually means better performance, and my car does perform better from a drivers seat experience. R [/QUOTE]
