Since this is no longer about the original topic..
I'll just say it's really simple: The vehicles need to be in the same ballpark as far as the power-to-weight ratio is concerned, for them to be close to equal. Assuming of course a competent rider and driver.
Youtube is filled with sketchy street races, filmed at night, while running past traffic. All those so-called "racers" are dumbasses.
If they really want to prove something, take it to a venue where the performance of the vehicle can truly be accurately measured. No boasting, no BS, no excuses.
