you know guys, maybe one of these days you'll convince me but then again you really don't have to either
Its just that you see all these claims for this product whether the unorthodox, 3SX, or some of the less known brands but where are the dyno numbers on our cars??
There was just an article in one of the magazines, they did a dyno test on some other car, I forget, with one of the underdrive pulleys and at 6000- 7000 rpm there was around a 7 HP gain. But this was an underdrive pulley and the increase was due to the slower turning accessories (underdrive), therefore less
parasitic losses. Unless your at the drag strip or AutoX, how often do you hit 6-7K rpm? Ok, some of you do on a daily bases and for those of you that do, ok you get 7 HP at 6k rpm. Then theres the rotating mass point, this is easy to understand, simple physics. Yep when you accelerate it will require less HP beause your about 4 lbs lighter, but in HP terms not very much.
If you really search the intenet for the topics of harmonics, they are brought up for every type of engine, auto, aircraft, boats, etc. True dragsters rebuilt the engine every race or at least after a couple races. I not ready to rebuild my engine that often. Look at it another way if your planning on making some real HP you will replace your pistons with something like JE's Now if you run 10 hp more then stock with JE's and your engine blows up, not a very good mod, right?? In my terms a good mod is a performance enhancer without negative side affects and certainly its not a performance decreaser.
Alright, alright I'll quit
