Hi Stephen (or is it Steve?),
I just don't buy that pipes alone are going to get you a 28% gain on a stock setup. Doing the math, that would add roughly 15hp. The specs call stock hp at 54 so this would have to result in 69hp! Just for pipes? So what happens if you then rejet and add some free breathing air filters? Would you get another 5-10% gain?
I would like to see a controlled test of stock and then add the pipes and re-test. I am always willing to admit when I am wrong.
My thoughts are that if you open up the exhaust and the intake, jet accordingly, you will get about a 20-25% gain OVERALL. Or about 64-67hp. I've also heard good things about the TBS needles.
I have K&Ns, 160 mains, and Epcos and she runs like a demon. I finally found a dyno here and I will be there next week. I will most assuredly post the results. I think I have her fairly close to as much as I can get without some major change.
I guess I will find out exactly how good a wrench I am
