Yeah-you can't believe the ads,otherwise,for 7-800 hundred bucks would have a 500hp motor
Almost all tests are done on modified motors unless otherwise specified...
as in the previous posts,your biggest gains will be driving talent,gears and sticky tires...if you can drop that temp on the motor before running and stick a 1.90 sixty with the 410s you will have your goal...
remember-driving technique is everything..I know guys with SC'ers launching consistent 1.9-1.95 on street tires...practice..and until you compete-don't worry about the light or the guy next door-its your race.
