It depends On your Rev Limiter .. 6700 I think is the stock rev limiter ..with that being said 1.87 Gears 6700 RPM'S 7% Slip Is around 82 MPH ...Which a 225 Will Pull a 26 To the Limiter Quick.. At 7000 Rpms Will Be around 86 Mph..This is all an pretty goof relible estimate Not exact though .. Just My 2 Cents :very happy
