[QUOTE="2 Old 2 Rusty, post: 3256273, member: 42941"] [COLOR=Red][B][I]I'm no expert[/I][/B][/COLOR] but here's what I know; The answer to that question is both, yes & no. Yes, in the sense that some of them really does that. They have a lab looking place where they hook the engine up on a different type of dyno (I can't recall what they call it) & really only dyno the engine alone (removed from the car, minus the transmission & stuff). But here in M'sia I think only Proton has that machine, so I heard. No, in the sense that most dyno shops I've seen is probably done through a calculation through the dyno machine. Generally on older engines, is about 25% loss when the power gets thru to the wheels. Auto trans suffer more transmission loss; at about 30%. So I'm guessing that Scottwrx's figure should be somewhere around: 160 x 0.75 = 120 ps on wheel as shown in the bottom graph like he said. My BT AT is 112 ps on wheel; standard. So the calculation should be: 160 x 0.7 = 112 ps on wheel. [/QUOTE]
