<DIV>About 1979, when I was racing Drag Boats, in Oklahoma City I was pitted next to a top fueler. Their engine was removed from the boat and completely torn down between passes; the custom ground billet crank was changed for a new one after every 12 runs, but detail inspected after each run. (A complete race usually meant anywhere from 6 to 8 passes, sometimes more.) There were separate crewmembers for the Blower, injectors, heads, magnetos, fuel, etc. at least 10 people. Looked like a ballet when the boat went on the trailer. I remember the crew chief asking the owner "do you want to win the next heat badly enough to waste 2 pistons?" The owner said, without hesitation, "Sure." When they tore down the engine after the next pass, sure enough, 2 pistons were history. Like they say: Nitro eats bank accounts. At that time, before the price went up, nitro was costing $1300 per drum. Several drums per
race.</DIV>
<DIV>Hope I don't get into too much trouble for being off-subject.</DIV>

<DIV>And best of all a top fuel dragster runs on Nitromethane, just like REAL model airplane engines do! LOL</DIV>

<DIV>I love high performance stuff and very few things are higher performance than a top fuel dragster. This puts it into perspective:</DIV>
<DIV> </DIV>
<DIV><SPAN style="FONT-FAMILY: 'Times New Roman', 'serif'; FONT-SIZE: 12pt"><STRONG>Acceleration explained.</STRONG></SPAN><SPAN style="FONT-FAMILY: 'Times New Roman', 'serif'; FONT-SIZE: 12pt"> <BR> <BR> <BR></SPAN><B><SPAN style="FONT-FAMILY: 'Arial', 'sans-serif'; FONT-SIZE: 10pt">* One Top Fuel dragster outfitted with a 500 cubic-inch replica Dodge (actually Keith Black, etc) Hemi engine makes more horsepower (8,000 HP) than the first 4 rows at NASCAR's Daytona 500. <BR><BR>* Under full throttle, a dragster engine will consume 11.2 gallons of nitro methane per second; a fully loaded Boeing 747 consumes jet fuel at the same rate but with 25% less energy being produced. <BR><BR>* A stock Dodge Hemi V8 engine cannot produce enough power to merely drive the dragster's supercharger. <BR><BR>* With 3000 CFM of air being rammed in by the supercharger on overdrive, the fuel mixture is compressed into a near-solid form before ignition. Cylinders
run on the verge of hydraulic lockup at full throttle.</SPAN></B><SPAN style="FONT-FAMILY: 'Times New Roman', 'serif'; FONT-SIZE: 12pt"> <BR></SPAN><B><SPAN style="FONT-FAMILY: 'Arial', 'sans-serif'; FONT-SIZE: 10pt"><BR>* At the stoichio metric 1.7:1 air/fuel mixture for nitro methane the flame front temperature measures 7050 degrees F. <BR><BR>* Nitro methane 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. <BR><BR>* Dual magnetos supply 44 amps to each spark plug. Which is typically the output of an electric arc welder in each cylinder. <BR><BR>* Spark plug electrodes are totally consumed during a pass. After 1/2 way thru the run, the engine is 'dieseling' from compression and the glow of the exhaust valves at 1400 degrees F. The engine can only be shut down by cutting the fuel flow. <BR><BR>* If spark momentarily fails early
in the run, unburned nitro builds up in the affected cylinders and then explodes with enough sufficient force to blow the cylinder heads off the block in pieces or split the block in half !! <BR><BR>* Dragsters reach over 300 MPH +... before you have completed reading this sentence. <BR><BR>* In order to exceed 300 MPH in 4.5 seconds, a dragster must accelerate an average of over 4 G's. In order to reach 200 MPH well before reaching half-track, at launch the acceleration approaches 8 G's. <BR><BR>* Top Fuel engines turn approximately 540 revolutions from light to light! <BR><BR>* Including the burnout, the engine must only survive 900 revolutions under load. <BR><BR>* The redline is actually quite high at 9500 RPM. <BR><BR>* THE BOTTOM LINE: Assuming all the equipment is paid for, the pit crew is working for free, & NOTHING BLOWS UP, each run will cost an estimated $1,000 per second. <BR><BR>0 to 100 MPH in .8 seconds (the first 60 feet of t he run)
<BR>0 to 200 MPH in 2.2 seconds (the first 350 feet of the run) <BR>6 g-forces at the starting line (nothing accelerates faster on land) <BR>6 negative g-forces upon deployment of twin 'chutes at 300 MPH</SPAN></B><SPAN style="FONT-FAMILY: 'Times New Roman', 'serif'; FONT-SIZE: 12pt"> <BR></SPAN><B><SPAN style="FONT-FAMILY: 'Arial', 'sans-serif'; FONT-SIZE: 10pt"><BR>An NHRA Top Fuel Dragster accelerates quicker than any other land vehicle on earth . . quicker than a jet fighter plane . . . quicker than the space shuttle....or snapping your fingers !! <BR><BR>The current Top Fuel dragster elapsed time record is 4.420 seconds for the quarter-mile (2004, Doug Kalitta). The top speed record is 337.58 MPH as measured over the last 66' of the run (2005, Tony Schumacher). <BR><BR>Let's now put this all into perspective: <BR><BR>Imagine this...........You are driving a new $140,000 Lingenfelter twin-turbo powered Corvette Z-06. Over a mile up the road,
a Top Fuel dragster is staged & ready to 'launch' down a quarter-mile s trip as you pass. You have the advantage of a flying start. You run the 'Vette hard, on up through the gears and blast across the starting line & pass the dragster at an honest 200 MPH.... The 'tree' goes green for both of you at that exact moment.</SPAN></B><SPAN style="FONT-FAMILY: 'Times New Roman', 'serif'; FONT-SIZE: 12pt"> <BR></SPAN><B><SPAN style="FONT-FAMILY: 'Arial', 'sans-serif'; FONT-SIZE: 10pt"><BR>The dragster departs & starts after you. You keep your foot buried hard to the floor, and suddenly you hear an incredibly brutally screaming whine that seares and pummels your eardrums & within a mere 3 seconds the dragster effortlessly catches & passes you. He beats you to the finish line, a quarter-mile away from where you just passed him. Think about it - from a standing start, the dragster had spotted you 200 MPH.....and it not only caught,
but nearly blasted you off the planet when he passed you within a mere 1320 foot long race !!!! <BR><BR>That, my friends.....is acceleration.</SPAN></B><SPAN style="FONT-FAMILY: 'Times New Roman', 'serif'; FONT-SIZE: 12pt"> </SPAN></DIV></TD></TR></TBODY></TABLE></DIV><BR>-----Inline Attachment Follows-----<BR><BR>
