A stock BMW 850CSi, S70B56 engine (not Mclaren S70/2) with an I.T.B. down draft intake system on the dyno at a shop called The Power Plant. This is a power run up to the rev limiter and then back down to cool off. You can see the engine jump a little as it reaches max rpm. Check out racingpowerplant.com
