I read in Pete Lyons' Can-Am book that the Chaparrals were left-foot braking only, (a shield prevented RFB), there was no clutch pedal, and the 3rd pedal was used to adjust the wing and flap. Is this all correct?

Just a hint on setting the gear ratios for Chaparral; don’t spread the 3 gears out, but think of the torque convertor as first gear and then set the others as if they were 2nd, 3rd and 4th.  :)

Ah, so that is why I can not get off the line, no wheelspin possible :-(

That's not realistic!

It's also going to be a problem when I finish my new cockpit where the steering shaft prevents left foot braking  :lol:

The 2F had a pedal to operate the wing where a normal car would have a clutch pedal.  The wing was normally at the maximum down force angle and pressing the pedal would move it to the minimum drag angle.  The driver would press the pedal coming out of the corner so the car had minimum drag down the straight.  When he reached his braking point he would take his foot off the wing pedal and push the brake pedal.  The wing would then be at its maximum down force and drag angle when braking and cornering.

You can watch the wing in action in the CanAm series here:



Jim Hall in his Chaparral is featured all the way through this video, but you can see him flipping the wing at several instances, like at 2:30 for example.

:wave: Tommie.

here you are.A close look to the 2F pedals, thks to Auto Passion mag

All GPLers are kindly reminded to update  and order a dedicated pedals set when driving the 2F :2c: :2c: :2c: :2c: :P

Jim Hall on a very private interview said : "that car was called 2F because of the driver racing two foot pushed together "

  True
  
  False
  
  Don't know

  Please, you can all take your good fortune by filling the correct answer :confused:

  ... answer will be found in  the next Chap 's Mag  :yeah:

So my GT40 lap time is more than 3 secs off the pace. :(

I hate that place!

Remco, why GPLRA says that it calculates time of lap 4m 27.911s instead of what says 2m 40.747s. ?
Because you used 60Hz?
