Nitromethane is a slower burning fuel compared to pump gas, and only produces ~11MJ/kg compared to pump gas at ~43. It's advantage is that it can be a mono-propellant in that it doesn't require addition oxygen to burn, and by weight you can pump in 8 times more fuel. The pumps use fuel lines the size of conventional radiator water hoses.

An injected nitro car doesn't have gears - it's geared to spin ~6200 through the trap. The computer controls the ignition advance etc for any rpm during the run, which influences the hp being produced at a particular speed.

With you doing 200mph and the Rail doing a 4.5 second run you'll tie at the trap. There'll just be a slight difference in your speeds.
