A Stihl BR 600 produces 712 cfm -1012 cfm at a speed of 201mph. That would work and a Supercharger/turbo.

this thread reminded me that i had this saved. check it out

> Under full throttle, a dragster engine consumes 1-1/2 gallons of nitro
> methane 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's supercharger. With 3,000 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 (stoichiometry: methodology and technology by which
> quantities of reactants and products in chemical reactions are determined)
> 1.7:1 air/fuel mixture of nitro methane, the flame front temperature
> measures 7,050 deg F. 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.

> Dual magnetos supply 44 amps to each spark plug. This is essentially the
> output of an arc welder in each cylinder. Spark plug electrodes are totally
> consumed during a pass. After halfway, the engine is dieseling from
> compression, plus the glow of exhaust valves at 1,400 deg 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 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

> The redline is actually quite high at 9,500 rpm.

> Assuming all the equipment is paid off, the crew worked for free, and for

> The current top fuel dragster elapsed time record is 4.441 seconds for the

> You are driving the average $140,000 Lingenfelter 'twin-turbo' powered

> The dragster launches and starts after you. You keep your foot down hard,

> Think about it; from a standing start, the dragster had spotted you 200 mph
