You don't need 100 Electric HP to get a 2,000 lb vehicle to 70 or 80 MPH. My car only has one 19 HP motor and its 3400 lbs and I can get up to 70 or 80 MPH. Unless you weren't trying to build something efficient and wanted a the extra HP. Do you happen to have more details of this build that you could share instead of people shooting into the dark? But from the details you have given us, it sounds like an ETek motor is what you are looking for.
