Yep, they get longer when they are worn out.I never even knew that was a thing.

The circle track guys happily throw away aluminum rods and valvetrain because it's cheaper to replace it than risk it and need a new engine.
I guess when you're in the business of destroying engines with fucktons of horsepower you probably don't have a lot of parts aging out.

IHRA?Motor makes somewhere in the neighborhood of 12,000hp running 98% nitro. Needless to say they don't run with the NHRA.
You don't. The clutch pack slips the entire length of the track and never fully locks up. I don't get it either.... Clutch is on a timer and run by air. When you let go of the button it starts the clutch timer and it progressively gets tighter..

I've always found this fact list interesting.
- One dragster's 500-inch Hemi makes more horsepower then the first 8 rows at Daytona.
- Under full throttle, a dragster engine consumes 1 1/2 gallons of nitro per second, the same rate of fuel consumption as a fully loaded 747 but with 4 times the energy volume.
- The supercharger takes more power to drive than a stock hemi makes.
- Even with nearly 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into nearly-solid form before ignition. Cylinders run on the verge of hydraulic lock.
- Dual magnetos apply 44 amps to each spark plug. This is the output of an arc welder in each cylinder.
- At stoichiometric (exact) 1.7:1 air/fuel mixture (for nitro), the flame front of nitromethane measures 7050 degrees F.
- Nitromethane burns yellow. The spectacular white flame seen above the stacks at night is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases.
- Spark plug electrodes are totally consumed during a pass. After 1/2 way, the engine is dieseling from compression-plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by cutting off its fuel flow.
- If spark momentarily fails early in the run, unburned nitro builds up in those cylinders and then explodes with a force that can blow cylinder heads off the block in pieces or blow the block in half.
- Dragsters twist the crank (torsionally) so far (20 degrees in the big end of the track) that sometimes cam lobes are ground offset from front to rear to re-phase the valve timing somewhere closer to synchronization with the pistons.
- To exceed 300mph in 4.5 seconds dragsters must accelerate at an average of over 4G's. But in reaching 200 mph well before 1/2 track, launch acceleration is closer to 8G's.
- If all the equipment is paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs $1000.00 per second.
- Dragsters reach over 300 miles per hour before you have read this sentence.

Thats gotta be about the coolest thing I've ever seen!! I'm just imagining the forces required to do thatGuy I work with runs a nitro funny car. They were racing in Ennis a couple weekends ago and the engine "sneezed" when they went to fire it up. Apparently one of the injectors was dripping into the cylinder and as the piston moved up in the bore it hydro locked that cylinder and then fired off causing this......
It split the rod straight down the middle!!!!
Mostly outlaw grudge races in fuel altered trim and once in a while they throw on a funny car body on it and run with the nostalgia guys.
They run the fuel altered called the "War Wagon" all over Texas and surrounding states. I guess it's a pretty famous car and team out here. They hold a bunch of track ET and MPH records around here.
This is what it normally does when the engine isn't splitting rods....
It's the gold car in the far lane in this video.
On board camera 1/8 mile run.

Good Morning!
Two co-workers have had that happen, one fixed it, the other one caught it just in time to trade it in and make it somebody else's problem.

When you crash so hard it rips the front axle out from under the rig and knocks the driver completely unconscious for a while. Put it together and got it on the podium 4 hours later.
2011 up superduty unit bearing on a 4 wheel steering buggy. Pulled the threads out of the retaining nut and the UB came apart.
The guts out of one of our ram assist steering boxes. The ram assist ram is a 2 1/2” double ended ram and still got enough force into it to explode the steering box
Tire rolled a rock up in between the tire and the shock. Separated the top cap from the shock body during a race. Didn’t stop till the race was over, totally murdered the coil over.

How did you pull the threads out of the retaining nut? Wedge the tire against a rock and have a battle of who is stronger?
Yes. My friends rig. Doing hard trail stuff, water in 42 krawlers. Got it in enough of a side bind to fail the unit bearing.

how much centrifugal force does it take to get a unbroke axle with a huge bend out of the axle tube. must have partial came out during the roll or something. way impressive for sure
May have come out mid roll and got the bent on its way out.

300M 40sp spidertrax stub shaft in a rock bouncer.
Interestingly the CTM ujoint made it almost unscathed.
Spindle was fucked and had to be cut.
Bumping this post up.
Friend broke another Spidertrax 40sp stub shaft. Very similar to this one, but no pics.
Current tally is about 1 stub per year. Parts take 2 to 3 months to show up.
Something will have to be done because this obviously ain't cutting it.

A LOT. This is the words from the photographer “I don’t think I’ve ever witnessed a car disassembled before my eyes”
Zoom in on these and look at the fluids blowing out of things as their being exploded
