Here is some amazing dragster information that you may find interesting:
* One Top Fuel dragster 500 cubic inch Hemi engine makes more
horsepower than the first 4 rows at the Daytona 500.
* Under full throttle, a dragster engine consumes 1½ gallons of
nitromethane per second; a fully loaded 747 consumes jet fuel at the same
rate with 25% less energy being produced.
* A stock Dodge Hemi V8 engine cannot produce enough power to drive the
dragster supercharger.
* 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 lock at full throttle.
* At the stoichiometric 1.7:1 air/fuel mixture for nitromethane the flame
front temperature 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 vapour by the searing exhaust gases.
* Dual magnetos supply 44 amps to each spark plug. This is the output of
an arc welder in each cylinder. Spark plug electrodes are totally consumed
during a pass. After ½ 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 the fuel flow.
* If spark momentarily fails early in the run, unburned nitro builds up
in the affected cylinders and then explodes with sufficient force to blow
cylinder heads off the block in pieces or split the block in half.
* In order to exceed 300 mph in 4.5 seconds dragsters must accelerate at
an average of over 4G's. In order to reach 200 mph well before half-track,
the launch acceleration approaches 8G's.
* Dragsters reach over 300 miles per hour before you have completed
reading this sentence.
* Top Fuel Engines turn approximately 540 revolutions from light to
light!
* Including the burnout the engine must only survive 900 revolutions
under load.
* The redline is actually quite high at 9500rpm.
* The Bottom Line; Assuming all the equipment is paid off, the crew
worked for free, and for once NOTHING BLOWS UP, each run costs an
estimated $1,000.00 per second. The current Top Fuel dragster elapsed time record
is 4.441 seconds for the quarter mile (10/05/03, Tony Schumacher). The top
speed record is 333.00 mph (533 km/h) as measured over the last 66' of the
run (09/28/03 Doug Kalitta).
Putting all of this into perspective:
You are driving the average $140,000 Lingenfelter "twin-turbo" powered
Corvette Z06. Over a mile up the road, a Top Fuel dragster is staged and
ready to launch down a quarter mile strip as you pass. You have the
advantage of a flying start. You run the 'Vette hard up through the gears
and blast across the starting line and past the dragster at an honest 200
mph. The 'tree' goes green for both of you at that moment. The dragster
launches and starts after you. You keep your foot down hard, but you hear
an incredibly brutal whine that sears your eardrums and within 3 seconds
the dragster catches and 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 not only caught you, but nearly blasted you off the road when he
passed you within a mere 1320 foot long race course.
That, sports fans, is acceleration.

and those are not the bilge blowers off ebay...
It is all about moving air!!!! Simply put , If you can create the most vacuume you can create the most boost on the other side of that vaccuume!!
Nickleinenon, that is the first time I have seen a 12psi job! They are getting closer
Gentlemen, what would an extra 12psi do for your rig?
(Outside the box!)
