may be totally wrong here but just a thought. would it not have an adverse effect by opening the butterflys too much and hence effectivly starting to close them again as they pass the 90 deg mark?
just a random thought thats all.
that occurred to me too, although wouldn't the butterflies have a stop built into them at 90 degrees? Otherwise cars would have to be calibrated to have the butterflies set wide open at the end of throttle pedal travel, and in these pre-fly-by-wire cars, cables stretch over time!
The butterflies can't open more then 90° in the inlet plenum. So no problem there, although the cable will strech and could snap in time...
So take the throttle stop out and put a long M6 bolt in with 2 nuts to tighten it up in the chassis instead. Works a treat
ok, so no problems really - there is flex in the throttle pedal itself; I'm guessing Nissan designed it that way as people would be kicking it form heel-and-toe, and generally flogging it.
I'm very progressive and gentle in my throttle inputs (you have to be at this power level!) so I'm not too worried. Worst comes to worst, my engine goes to idle and won't drive, and I end up replacing a cable.
