Just an observation and not disputing anyone or trying to be contrary. But I just went through several pages of Dyno results and I found it very interesting. I have had some mild builds using the same cams, air cleaner and same or similar mufflers as some of those listed. And I had the bikes tuned by a well respected tuner. What is different is that some of those Dyno sheets show a 15 hp and 15 lb ft gain over what I got on basically the same build. And I am talking about very mild builds. That is one hell of a difference even given the difference between Dyno's. Must be a lot of really happy Dyno's out there.

I don't know how true it is, but I've heard that you can get widely different results due to weather conditions alone, and from dyno to dyno.

 

just had some work done on my 2003, http://jprecision.com/twin-cam/ the stage IIB heads and redshift cams, dyno tune with direct link.

 

My current build has been ran on three different dynos all numbers are corrected. It went 116/116 when tuned, 110/109 on another dyno at a local shop having a shoot out and 121/122 at a rally shoot out. Same bike with no changes, three different sets of numbers. The highest set of numbers was in 95 degree heat and high humidity, the middle set was in winter...should be the other way around.
I take dyno numbers with a grain of salt but the curves are useful. I always like to see a good tabletop torque curve.

 

I have to Agree with the both of you (FLS103 and Martin10). There are definitely some "Happy" Dyno's out there. It's hard to really put trust in some of them. I will say though one of the few bikes I've heard and know a little about is Target64's 107 build.
He has a post out there somewhere that will satisfy some...
I have to say that I truly believe that his numbers are real, I also have to say that the builder who helped to bring it to life is also for real. Hopefully some of you guys out there can tell the difference and not get Taken... I should have left my 83" W8 build alone.

 

There are happy and heart breaker dyno's. When I had a hot rod shop we had a heart breaker Superflo which was a load control dyno and the bomb for tuning for driveability etc. But it didn't have a big happy peak number. Down the road they had a Dynojet that would spit out 750rwhp when ours showed 680. He got lots of business but when the lights dropped and the BS stopped, seemed like our 800hp cars always outran his 900hp cars lol.

 

The truth will always last longer than the lies.........
