Michael, The short answer is yes, you can probably get equal power but be aware that batteries weigh more than gas so chassis weight might go up and then you need more power for the same performance.
An electric motor is a different beast from an ICE motor. They are often hard to compare because you must consider the whole package. If you can get a torque curve for the electric motor that will help give you an idea. The curve will change for different voltages. The curves are usually the ideal from a steady voltage but batterie voltage sags under load. Gear boxes waste power but are essential for an ICE motor. Was the gas motor rated at the flywheel or wheel? Using a more powerful electric motor and no gear box might give you the performance and improve efficiency. Also consider the flexibility of multiple motors. The friction in a differential wastes power. Two motors side by side gives an electrically control diff with no friction loss. 4 wheel drive offers even more scope for innovation ( torque vectoring ) but gets complicated. Sometime simple wins. Did you see that an electric won overall in a recent Formula Student event? http://www.racecar-engineering.com/news/eth-zurich-males-history-at-formula-student/ Cliff www.ProEV.com > On Nov 8, 2013, at 6:26 AM, MichaelNot <[email protected]> wrote: > > Good afternoon, > > I am currently doing a project at university looking into the feasibility of > turning the current petrol formula student racecar into an EV.
