you know that MPH is
rpm x tire
------------
gear ratio x 336
3000 x27=81000
3.05x336=1024.8 81000 div by 1024.8 = 79.3MPH that stock
3000x26 =78000
3.05x336 =1024.8 78000divby1024.8 = 76.11 MPH that what im running in the summer 1 inches shorter tires
3000 x27=81000
3.29 x336=1105.44 81000 div by 1105.44= 73.27 mph that what you be running at whit 27 inches tires in 3rd gear that 6 mph difference from stock
3000x25.5 =76500
3.05x336=1024 76500 div by 1024.8 = 74.8 mph so whit a 1inches and half shorter tires am almost the same that whit 3.29 gear
