As One More Time said, with that heavy car, and body design, hes running into a lot of factors that will slow the car down.
To do what you are thinking, would require dumping about 1000 lbs, and having an aerodynamic body.
Example are Pro Stock drag cars. These have very slippery bodies and are very light weight, pushing well over 2000 HP from thier engines.
IF you give a brick enough horsepower, you can make it fly.
1 lb ft of torque is 1 lb ft of torque, and it doesnt matter what kind of fuel or power plant you are using to produce it. The amount of work output is still the same.
