TRC P100D runs 10.4!

[shokunin]

In TRC's latest video, you can see the front seats are gone and replaced with racing buckets. The interior trim that is visible in the video has been removed as well.

yep, pretty big weight reduction... a full weight with pano car recently went 10.6 @ 125 and the 60' wasn't that great...

Are there any tires for the 19 inch rims you would recommend for best 1/4 mile times?

There are no tires that will give you a better 1/4 mile time than those that come with the car. The car's acceleration is preprogrammed to match the characteristics of those tires. If you use tires that have less tack than those, your performance will be worse, but a tire with more tack will not make any difference. Anything you can do to reduce weight like lighter rims will help.

You could try drag radials from companies like M/T, Mickey Thompson, or Nitto but those will be more than terrible on the street. I don't believe anyone has tried drags on these cars. It's an expensive experiment that will likely not provide any discernable difference in 1/4 mile time except drag strip.

yea, the sling shot effect of a drag tire might help a little, but not worth it...

I Agree.

Drag radials won't help much anyway unless you can heat them up.

10.700s to 10.444s implies 5000 lbs to 4650 lbs.
Now, if he can get it down to 4080 lbs then 9.999s.

I just listened to trc's video on stripping their p100d. He said they have removed 360 lbs. That's pretty close to the 350 lbs I estimated.

Interesting. Weight has consequences. In this case roughly 140 pounds for a tenth. That's about the addl weight of a pano roof vs solid.

He had to go to stickier tires, too.

Did they remove the frunk liner?

The general rule of thumb in an ICE car has always been 100lbs per 1/10th of a second; interesting.

The ratio of 1/4 mile times cubed is equal to the ratio of the weights. t2 / t1 cubed = w2 / w1, so w2 = w1 * (t2 / t1)^3.
(10.444s / 10.7s)^3 * 5000 lbs = 0.93 * 5000 = 4650 lbs.

5000 - 4650 = 350 lbs difference for these times and weights.

Using this same formula, 10.7 to 10.6 would require about 138.9 lbs.
A 5000 lb car would have to loose 100 lbs to drop from 15.1 s to 15 s
