dont forget most all dynojet dynos are run under acceleration tests and not load testing. This is simply a matter of this dyno graph showing a bike on a acceleromter pretty much...
none the less I believe rims will let you release more hp but this is just another way to sell wheels, people love hp numbers....
thanks for the graph!
yep....pretty much what I was getting from both posts.....nice thread though just was trying to get into a little more perspective of what it means. ccasion1Remember HP is a calculated number. The lighter BST's showed a higher HP number because of less work required to rotate the wheel at said RPM. But to say it makes more power is a bit inaccurate. The engine still makes the same HP and Torque as stock. Just the numbers are skewed a bit due to the type of dyno and reduction in rotating mass.
I do somewhat agree with you, but if you did this same test on a load cell dyno you wouldnt see any difference because its not measuring how fast you can spin a durm your measrung how much torque can be placed on a torque arm.Same RPM's, idle to 14K, just got there faster, NO INCREASE IN RPM as you state. Thus more work was performed. 6 more HP to the road. You cant change physics anymore than I.
hey now, leave my alien friends alone! :lol:From what I can find, (admittedly mostly on the internet) most scientists agree that the laws of pyhsics, as we know it, would apply across the Universe. Thus, any aliens looking to come here would be bound by the unfortunate fact that light speed isn't possible as we know physics. Since we know there are no known habitable exo-planets, and probably not any in our part of the Galaxy, I would say it is a safe bet, there are no aliens on their way here as the void is to great to breach.
Maybe we need to find a way to increase the RPM's (as you state the case is) instead of how fast we get to the same RPM, but you duh, well you know.
they crashed in the desert because of all the radioactivity threw their systems off from all the nuclear bomb testing :thumbsup:If Aliens had the technology to cross the great distances, why then with this great technology do they always seem to crash land when they get here? I mean we can loand our spaceships pretty routine. If Aliens have this massive increase in knowledge over our own, and what it would take to cross the great voids, I doubt they would crash land everytime they get here.
NO, I dont care the thread has gone to shit,
You are absolutly correct but once again we are comparing apples and oranges. I know if I put lighter wheels on my rate of acceleration would be greater due to a decrease in load thus yes mechanical HP is increased. I do not need a dyno to tell me that. But I guess the dyno numbers do put those gains into some sort of perspective. As far as dyno numbers go I care only to know what gains were made from the engine itself and as its not very cost effective to remove an engine to place on an engine dyno my only option is a load wheel dyno. But that is my opinion.If you lighten the internals on an engine itself, does the same engine with lighter internals make more power? Anything connected to the crank that decreases load will yield higher numbers.
If you put identical engines in two different chassis weighing differently that would be a measure of acceleration between the 2 engines. But effectively changing the load on engines moving parts changes its output. Hence HP at the crank and HP at the wheel.
By reducing torque load on a engine you increase mechanical horse power.
