Drag race time from Flying H Drag Strip

[A-AY-RON]

Yep, CyberBeast Foundation on Cyberwheels and the Goodyear AT tires. The first pass I was able to do about 20 minutes after charging so the battery was still up to temp.. 2nd pass we had to wait because there was a crash on the track then a couple of gas cars dumped antifreeze and they had to dry the track so the battery cooled down. 3rd pass I preconditioned for 10-15 minutes . I ran the first pass with the tonneau open. 2 nd with it closed and 3rd with the tonneau and tailgate open. . 1st pass was a 10.969 ET @ 118.89 mph. 2nd pass was 10.963 ET@ 119.27 MPH. 3rd pass was 10.88 ET @ 118.88 MPH.
I’m trying to figure out now if there is a way to recalibrate the speedometer for 32” tall tires since that’s the tallest drag radial you can buy right now. Otherwise Im worried dropping to a smaller tire will give me a better launch, but without the speedo being corrected I’d hit the 130mph limiter before the end of the 1/4 and likely run the same time due to the limiter. 32” tall tire would read about 10mph on the truck speedo uncalibrated.. it’s $2k for drag radials so I don’t want to buy those until I’m sure I can get the speedo corrected.

I was just about to ask about this; hitting speed limiter too early, w/o calibration.

On my Blue FS beast I hit 137, I ran out of road on I-95 N in NC traffic. I wouldn’t worry about the speedo, but definitely the calibration. I think it will go as high as The car will go.. meaning well past 140. Somebody said there was a Reiff calibration for the tires. But I have yet to find it. I think when they put 22 or 24 is on there’s a setting. Definitely check with discount tire it’s worth a phone call.! Keep pushing the limits! The beast definitely have more in them!

I’ve always wondered what a complete reskin of a Cyberbeast where all of the stainless body panels where replaced with carbon fiber and how it would perform on the drag strip. ChatGPT indicates that it could shave off 600lbs and .35s off of a quarter mile.

I asked AI to calculate the G force of accelerating from 0 to 60 in 2.5 seconds and the calculation was 1.09 g force. Impressive as hell. No wonder passengers scream when I demonstrate the acceleration.
I wonder if AI could calculate times with accuracy replacing the SS with carbon fiber panels and Mickey Thompson racing tires?
Also with just the racing tires not changing the panels. If you post the results we'll see how accurate AI model is compared to actual results.

Cybertruck runs some consistent 10.9’s on the AT tires.

10.887 was the lowest time and 119.27 fastest mph.

Ordering some Micky Thompson ET Street Ss tires this week that are 2” shorter and see if it can drop a couple of tenths.

I hope you publish the results after your tire upgrades. Very impressive.

I can’t wait to to see your results Mickey Thompson ET Street SS tires! I’ve been waiting for someone to post some 0-60 and 1/4 Mile times with some sticky tires!

Last year when I ran mine 10.9 was my best, but I was running into the 113 mph limiter. Have yet to verify that has been lifted to 130 at least on mine.

TLDR: The choice of materials adds very little weight, it saves weight over a mild steel exoskeleton that would be much less damage resistant.

The Tesla haters have come up with ridiculous weights for the cold-rolled stainless steel panels. Using 47 sq. feet of doors at 1.8mm thick and 62 sq. feet for the remaining exterior panels, I come up with around 300 lbs. total weight of cold-rolled stainless steel panels. This doesn't include the weight of the brackets and bolts used to bolt it to the rest of the chassis. It doesn't include the weight of the inner door panels. I could be off by 20% in either direction as I only took rough measurements of irregular shaped panels.

Using a density of 2.95 lbs. per sq. ft. for the 1.8mm doors and 2.30 lbs. per sq. ft. for the 1.4mm bodywork, gives an outer door panel weight of 139 lbs. and the remaining panels weighing 143 lbs. or a total cold-rolled steel weight of 282 lbs. If I underestimated the square footage by 20%, that would be 338 lbs. total.

Using carbon fiber doors would require the addition of side crash intrusion protection bars in every door, adding perhaps 24 lbs. (6 lbs. per door). Keep in mind that carbon fiber is not very strong in compression, a huge net negative for the rear sail panels that stiffen the rear of the chassis around the bed area. It would mean much thicker carbon fiber would be needed there. Even if 150 lbs. of carbon fiber panels (in total) were sufficient for the necessary structural loads (doubtful), and reasonable strength in other areas to withstand common light bumps and impacts, that would be a total weight savings of only 188 lbs. (not counting the required addition of side impact anti-intrusion beams). Granted, this ignores the weights of the steel brackets, bolts and structural adhesive used to affix the stainless steel to the rest of the chassis, but a method would need to be devised to affix the carbon fiber sail panels to the chassis in a manner that could carry the same loads (unless one was willing to give up some chassis rigidity and nerf the 2500 cargo capacity).

One downside to this relatively small savings in weight would be that the carbon fiber would require UV protection in the form of some kind of paint. The Cybertruck would go from being the toughest, most damage resistant truck on the market, to the most fragile truck ever built. Your quarter-mile time would improve in a manner that could only be detected by accurate timing instruments. Bullets would go right through the truck. When off-roading in mud and brush, the carbon fiber and paint (or protective clearcoats) would take a real beating. Door dings would be a thing again. Crash safety would need to be re-engineered to not suffer. Time spent maintaining the exterior would skyrocket. All for an imperceptible increase in 1/4 mile times and a miniscule increase in efficiency. You might even save $100 per vehicle, if painting costs didn't totally wipe out any savings (much like carbon fiber, that stainless is not cheap to buy or work with).

Elon created a real thing here, a truck that doesn't just claim to be tough. The extra-hard stainless steel comes at a higher dollar cost, but given that a truck like this could easily last 20 years or more, it could easily save money in the long-term. It doesn't come with a big weight penalty because the materials engineers at Tesla worked hard on the metal specifications, and they way they further harden it as it comes off the roll in their factory, to reduce the metal thickness from 3mm down to 1.4-1.8mm, while still essentially meeting their original design goals (except for cost). It's a material well-suited to it's application of building a tough truck.

For comparison, let's look at the lightweight aluminum bodied F-150 Lightning Platinum with 300 miles of EPA range:

It has no tonneau weight (as opposed to the included motorized hard tonneau that vanishes from sight when it's not needed). That alone probably adds 200 lbs. of non-structural weight to the Cybertruck. But the Ford is still heavier:

curb weight of 6,893 lbs. (vs. 6,669 lbs.)
the range is less at 300 miles with All-Season radials (vs. 320 with All-Terrain 35" tires)
and the payload capacity is only 1,800 pounds (vs. 2,500)

Faster, stronger, tougher, more agile, and more efficient. More bed volume, more features (like four wheel steering and fully adjustable suspension with up to 16" of ground clearance and active dampers), etc, etc, etc. All of these things add weight, yet the Cybertruck is still stronger and lighter. This advantage is due to better engineering and using the right materials for the design requirements.

Carbon fiber for a pickup truck?

That's all well and good, but I think he was just talking about get down strip faster, not truck capability. There is good reason why race cars use CF.

It would be a huge undertaking to replace all the stainless with cabon fiber, including engineering analysis, all to save, what, a hundred lbs.? It would have a barely measurable effect on 1/4 mile times.

Would be better off to buy lighter wheels and tires, take out the bed liner and motorized tonneau cover, remove rear seats, passenger seat, subwoofer and floor mats.

All stainless steel panels were removed on Shaquille Oneill’s Cyberbeast last year and replaced with carbon fiber

Replace n Rebuild
Most drag strip ICE rebuild their entire engine and trans 4-5 times a year.
The Faster 2s
Funny cars do engine swaps every run.
Tesla throttles the CT from the factory!
and
On the Tesla Plaid S even if you buy Upgraded Breaks and Upgraded Suspension Tesla factory still throttles back the Plaid S.
Tesla EV there is just too much Power to be allowed on the road or track.

Question?
Did you bleach your tires?
and
Were they slicks or road tires?

Didn’t bleach. I used to run ICE cars at the strip a d bleach was negligible on street tires. This is a new track and well prepped. I was just running the factory Goodyear AT’s for this trip. You can’t have good data without a good baseline. I’m still trying to find out if I can get the truck Speedo recalibrated for a 32” tire since that’s the tallest drag radial available from Micky Thompson at the moment. No use in buying drag radials if it pushes me into the top soles limiter sooner on the truck. I do have some Falken Wildpeak AT4’ in 32” tall I may try first before the drag radials. I would hate to spend $2k only to run slower

Don't be so gullible, it's a carbon fiber (look) wrap job, with carbon fiber fender flares. The stainless steel is still there. It probably added weight, not removed it.

Your AI is pretty spot on. See my g force meter during a 2.54 0-60 in the Beast:

Hey,
The fact that you can calculate g force at all is more impressive to me than AI doing it. But AI sure helps me keep up. I think my IQ increased 40 points since I started using it 3 years ago.

I think we should all put an asterisk next to our our IQ to disclose that we are using “performance enhancing drugs”

That’s the great thing about AI doing math and physics type stuff. There’s no opinions on X bogging it down with contradictory data while it tries to come up with the truth. Theres just a formula with a set of rules to follow. A good AI should always get the correct answer.
