Re: [EVDL] Heads Up vs Bracket Racing, the 'WIN' Light, and a Gear Ratio Change
I suppose the times will tell, but I would think a little acceleration early
on is better than acceleration later on, because then you are travelling
most of the strip faster, more area under the meat of the curve, as long as
you've got the traction to use the added low end and your rotational mass
isn't making the additional gear pointless. The four link should help keep
the traction from being the limiting factor, and siamesed, no flywheel,
direct drive motors will have less rotational mass than bigger motor and
flywheel or torque converter setups. One good thing about the Ford 9", if
you set up a few pumpkins, they are relatively easy to swap, and the bone
yards are full of pumpkins (at least my favorite one is).
This reminds me of the jet vs. funny car matches they used to run. The
funny cars would accelerate much harder off the line and be half way down
the strip before the jets got moving fast enough to generate much thrust,
then the jets would come on and try to make up the lost time and catch them
at the end. The ET's weren't that much different, but the jets had a lot of
But what do I know, I've only been down the quarter maybe 10 times. My
successes were in autocross. I really want to build a twin motor electric
Lotus 7 and carry the flag in autocross.
