Default Does my F seem slower than others?

So I watched different videos of other IS-F's ripping from 0-60 and 0-100 on camera and decided to try to make one of my own.

I noticed that on youtube, other IS-F's are ripping through 1-3rd gear like nothing, after making my video and comparing it to others it seems like my F goes through 1st and 2nd at a slower rate.

For example, here is my 0-97mph run. Pay attention to 1st and 2nd gear, it seems to pull slower..

Compared to Steve Meade's stock 2011 IS-F.

His car rips through 1st and 2nd so fast compared to mine. I'm starting to wonder if something is up with my car, Lexus did do a valve adjustment on my car for a "ticking" noise and I'm scared some incompetent tech might have screwed something up..

I always felt my IS-F didn't feel THAT quick from 0-70, after 70mph it pulls like crazy... lots of top end.

not very scientific but seems like the timing of your 0-60 in youtube time matches up about the same as his 'timer'


seems the same-ish to me.

Are you sure you're mashing the kickdown switch hard enough?

Elevation and outside temp will affect engine power. Traction will affect acceleration.
Maybe try again with VSC turned off and see if it gets any quicker. Or get some heat in the tires, and find the best pavement available.

Would the kickdown switch even make a difference in a zero start acceleration run?

I thought the kickdown switch was there to call upon a downshift in auto mode, well that's what it did in my 335i.

The kickdown switch has a very stiff spring in it from the factory. Lots of guys in the early days were not pressing the accelerator to the floor, only to where they contacted the kickdown switch.

youtube as well as phones compress video so that could be the reason.

Looks the same to me. Prob the video recording
yours is smooth and clear, his is shaky and blurry make it seem faster.

It will be interesting to see if the above is true.. we can try it out this summer. Both cars have similar mods, so it should be a good test.

From judging the video, your 0-60 was about 4 secs. Seems fine to me.
