So many posts erased??? Anyway here's what I posted:
WOW many posts here. First of all the torque that comes from the formula HP/rpm is not constant...it changes while you move from 0 - max rpm. HP changes too so that's why you see 2 completely different diagrams on the dyno screen. And that torque is the torque in the crankshaft of the engine that it stansfered directly to the pinion wich is connected tigtly to the crankcshaft via the clutch (FOXY: I don't add clutch and tire friction coefficients cause then the thing becomes REALLY complicated and only Matlab can help you to make graphic representation of all the dynamic variables. Practicly when you reach top speed the tires don't slip at all and the clutch is also 100% engaged so we skip these coefficients cause practicly they affect the final result only by 4-5% maximum. Now, all the other frictions from bearings, gears and also the air resistance are compacted in the engine's max practical rpm.So when we say that max theoritical rpm is 40k I calculate using 37k cause engine doesn't roll free and never reaches the theoritical number when car runs.)
So Qe=Qp cause they are as "one part" and they spin with the same angular velocity. So If you divide it with the pinio gear's radius you get different force amount for different radius.
ziggy12345: If I remember well these are the specs that Sirio had officialy anounced (with dyno sheet included) for the Siro .21 lamberto collari edition that I used on my ex EVOLVA. Now it's sold so I no more have the sheet to post
. I had posted pics of it 1 year ago (maybe more) but it's somewhere in this forum for sure.
PS1) Foxy is right about the educational standard here in Greece. And I could easily add friction air resistance etc to these "simplified" equations. But it would be worthless cause noone can measure the values needed for the coeficients setting without proper instruments. And Foxy my friend I REALLY appreciate your words!
Thanks!
PS2) Today I'm leaving on easter holidays with no internet available (thank God I'll stay away from technology for a while!!! I need spiritual recharge!!! LOL) and I'll be back in 2 weeks froms today! So pm or mail me and If I get a chance I'll check my mails. Have a nice time here and keep up the good work!
CU ALL SOON!!! [8D]
