how much horsepower is needed in order to go 200 mph at a standard acceleration rate?

depends on many factors. The largest are Downforce and drag. With a very aerodynamic car, you could hit 200 with around 450 hp, possibly less, assuming you could keep the thing on the ground, and you had a long, long straight.
With a high drag vehicle, it could take 650 or more, depending on how un-aerodynamic it is.
and more than anything, downforce matters the most, because if you cant keep the car on the ground, its hard to go 200 mph.

That would depend on the acceleration rate. There are several street-legal production cars which can reach and pass the 200 MPH mark such as the McLaren F-1 and the Jaguar XJ-220, but their acceleration rates vary depending on weight, aerodynamics, gear ratios, horsepower, tires, etc...
I had the rare privilage of working with some McLarens a couple years ago and they really will do 220 MPH, but to pull that off requires active aerodynamics (movable spoiler and nose fans), carbon-fiber monocoque body, 650 HP V-12 BMW engine, and exotic suspension, brakes, transaxle and wheels. As the speed increases, the resistance to speed exponentially increases as well due to wind resistance. This makes maintaining a standard acceleration rate nearly impossible and you will feel the rate drop off noticeably after the car passes 130-150 MPH.
I hope that's what you were looking for...

Your question is impossible to answer. there is no standard acceleration rate...acceleration is a measurement of change in direction. and to reach a speed of 200mph is dependant on many variables other than engine HP (drag,mass.time) .

to many things to work out . Car weight, drag coefficient, gear ratios, down force, time allowed, areo dynamic lift, usable rpms, tire size and quality, cooling package on the car, type of wheel bearings and grease type, other cars on the road, road surface.

Depending on the cars areodynamics and gearing, anywhere between 550-700 hp

prolly like 300-400hp...depends on weight too..and torque and im sure other things
