More questions of course.The scenario : '93 power at engine is rated 138.5bhp std. Dynoed at DMT got 100WHP. Dynoed at Links got almost the same figure. Third gear of course. ( The same car had been dynoed at Speedworks and N1 as well but showed a bit higher figure - but undestandable because of their type of dyno with N1 giving out almost 8% higher and Speedworks about 5% higher.)Now let we try to calculate the power at the engine. -New Power at engine = Std power at engine / power at wheels x New power at wheels.-New Power at engine = 138.5 / 100WHP x 100WHP= 138.5.BHPNow the Questions:a) Is the formula used correct?b) If it is correct, it shows the power loss through the drive train plus the beltings for aircond/powersteering/waterpump ect is 27.8%. c) Is it true that regardless of 3rd or 4th gear used, if we took the above mentioned formula to calculate the power, it will give a consistant, repeatable and acceptable result?d) From my observations, Proton Motorsports tends to give a much lower power loss % thus giving at the engine power a very low figure. What formula it uses? e) Top tuners around the world ( I'm talking US, UK and Aus) tend to use 3rd gear to dyno cars (na and force induction), I observe that my method/formula of calculating WHP and EHP is similar to them. That is not the case with R3.f) From my observations again, the honda cars will tend to show a higher WHP compare to Mitsubishi car ( on the same dyno calculated using above formula). Is it safe to assume that Honda has a lower drive train power loss compare to Mitsu? Anyones that has a good answer to my questions is welcome to give their opinions. Thanks in advance.Cheers.</blockquote>
