Why 2nd into 3rd isn't smooth ?
W
@RDS: very nice and the 2nd and 3rd gears are pretty weird. Must be the traction control stuff taming the engine.

@RDS: Well, what do you think?? It is losing traction and overpowering the rollers. Too much power for the roller dynos. Dynos are not meant to be ripping through gears in a very high horsepower car. They are supposed to be to measure power in a single gear (mostly 4th or 5th depending on which one has the overall ratio of 1:1)

That's a re-upload of an old vid. Here's another LFA dyno video that doesn't seem to have the same issue when shifting from 2nd to 3rd gear. http://www.youtube.com/watch?v=M1sX6AW_QCc

@Mister Two: It still is losing traction in 2nd and 3rd gear on the roller, but since the audio is not very clear it seems as if it was smooth. However, it is still clear that LFA is too powerful to blast like that on roller dynos.

@Joshd: Considering it topped out 4th gear at 9300 - 9500 rpm (or thereabouts) and knowing the gear ratios of where 4th gear ends, close to 170 - 175 mph.

Actually the presenter said 180 mph so there you go.

@RollaXRS: Well ... that explained the non-smooth-like gear change on 2nd to 3rd , it's seems like down a lot on power after shifting . Because of that , I prefer dyno the car by using the dyno that plug onto shaft / wheel lug .

Yeah, remember LFA's transmission does not let off the gas pedal after every shift. It keeps the throttle bodies (all 10 individual throttle bodies) open and slams the clutch in and out (just like powershifting in manual).

I got the feeling, that he jump over third gear, ie. "double" change straight from gear two to gear four (I´m no expert, what comes to cars technical side, so that maybe not even possible with that kind of gearbox (like it is, when using manual gearbox), that LFE has.

LFE???? Of course meaning LFA :-)
