Wanna see $100k in damage???
 

This engine was in a top fuel dragster of a friend of a friend. It kinda went boom at 600'. The total cost involved in completely replacing the engine was just under $100k.

Take care,

:eek: whoa dude thats crazy. :eek:

damn, that is pretty crazy. i wish i had a motor like that, but i wouldn't want to blow mine up becuase i couldn't afford to replace it.

I couldn't afford to replace the head gaskets on that thing.;)

Hey Chris, What are some of the more specifics on that baby. What block base is that, piston and rod info... I I assume its totally aftermarket DUH.. but what are some of the more specifics? Cubic Inches, Stoke.

Wow!! OMG that looks painful!!! :eek:

The basic costs are:

TXF block $8000.00
Heads $8,000.00 - $10,000.00
Crank $3,500.00 - $5,000.00
Blower $5,000.00
Injector (Hat) $5,000.00
Rods and Pistons $5,000.00

Thats just for the big stuff..

Some interesting Top Fuel dragster facts:

* 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 then 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 of it's 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.

that better not be the 429 your going to stick in my gt is it?:mad: , just kidding :D :D :p

:eek: wow :eek:

That's some pretty cool and amazing info about topfuel

Ah, put some JB weld on it. It'll be ready for another pass. :D :D

Dan.

Well I was thinking Liquid Steel but im sure JB would do just as good.
Bradley

Hey man, I swear by duct tape! OK Maybe duct tape AND JB weld.... :)

Cant forget wires ties ( zip ties ) Man if this combo wont fix it nothing will.

But whats the new thing im hearing bout? Something called "Welding" sounds like a farce to me...I mean c'mon, metal fusion.. Sheesh


Bradley

Chris, you make it sound faster then it really is. lol j/k that is freaking crazy!! I think I crapped myself just reading those stats. :rolleyes: :eek: :D

§am.

That is some interesting stuff man. I knew their fuel was pretty flamable and they changed plugs every run.

Burning h2 though, that's a whole different story. You think we could fit one of those in my car?

Is that the same motor that came stock in the cogsworth vega?

And doesn't the motor only make something like 600 revolutions during a 4.5 second run? 8000rpm/60*4.5 I think it is fewer than that because the average RPM is higher.

Those motors are amazing, and the crazy SOBs that drive them are...well...CRAZY.

What is this "WELDING" you're talking about!?

You could always use Elmer's Glue, just make sure you don't eat it ;)

NO!!!

Silly girl.

The Cosworth Option was an additional $260.

:D
