raptor 660's are faster than predators and almost identical to tld predators, and if you pipe them both the raptor gets more of an increase

 

it just so happens that i just got back from the dunes, and the 2 guys i went with had a 660 and a outlaw. my 450r beat them every time until i was halfway through 5th gear. the outlaw came out only 1/2 a bike length in front and the 660 was pulling. all bikes are stock.

 

that 450r is a mean mother fuc..er

 

I'm pretty sure though that if the 450r was geared a bit higher (just a bit higher than the Raptor) then it would probably be able to beat the Raptor in a drag because of power:weight.
