List of Engines
Stock engine stats, if you want to put your custom high compression boosted r6 pumping out 150 hp, make another table stuttgart
Guys we dont need to list every school that runs a yamaha r6 or other common engines, there are 500 teams who run the common engines. There's only one who runs a rotax, or a B&S, just cause the columns there, doesn't mean it needs to be filled.

Greater than Four Cylinder Engines
Although technically feasible, no OEM engines that are less than 710cc have more than 4 cylinders; so to have more than 4 cylinders would require either a custom crankshaft on a larger engine, or a completely custom engine block. Western Washington University built a custom V8 engine for their 2001 car, and are the only team to have had more than four cylinders.
