Welcome to the PF.

What is the context of your question? What vehicle is this small engine in? What speed is the vehicle moving? Is this just a paper calculation, a simulation, or do you intend to build it for a school project?
 
To calculate the power required to drive up a hill at a certain speed, calculate the vehicle's vertical speed (speed*grade), and then multiply by the vehicle's mass and G. The engine's dispplacement and cooling are not relevant in this problem.

[tex]V_{h}=V_{tot}*Grade[/tex]

[tex]P_{req}=M*g*V_{h}[/tex]
 
thnx for ur response.this is basically a school project and we have to build a three wheeler car, 2 wheels at the front and one at the rear and it is to be driven at 30kmph.thnx a lot once again.
