SteveR Posted June 9, 2008 Share Posted June 9, 2008 I've got a vid somewhere of the first of the recent set of Cosworth F1 V8s on a dyno. They rev it to 20k and it gets very red. Here we go Quote Link to comment Share on other sites More sharing options...

TLicense Posted June 9, 2008 Share Posted June 9, 2008 I saw the aftermath of a Mugen Honda MF-301HE that saw 24000rpm. In 2000 we had an issue with the gearbox rotary pot that relayed back to the ECU what gear it was in. We had a choice of two, the year before we used the larger one, but in an attempt to save weight, in 2000 we went for the smaller version. The problem was the smaller one would every now and then kind of "schiz out" and send spurious signals to back to the ECU. Because we had designed the gearbox casing to accept the smaller pot, we couldn't fit the larger one so had to carry the fault all season. In the Austrian GP, Frentzen was accelerating out of one of the corners, and was had just put the car into 5th, when the pot freaked out and told the ECU it was in 6th. The ECU was clever enough to know that it should have been in 5th, so downshifted just as he about to pull for the next gear. The RPM's peaked at a little over 24000RPM. (This was when the redline on most cars was about 16000RPM.) The net result was everything inside the engine grew by about 0.5mm and the pistons met the valves = Engine destroyed. There wasn't one part in the engine that could be re-used. Probably the best part of half a million quid gone up in smoke, for the sake of £20 rotary potentiometer!

SteveR Posted June 15, 2008 Share Posted June 15, 2008 In the first video, what's that behind the dyno; the open tray with a pipe leaking water all over the floor? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 15, 2008 Author Share Posted June 15, 2008 Probably the overflow from the air to water i/c most dynos use these days. Quote Link to comment Share on other sites More sharing options...
