| I run 15/50 but that's with a slightly different engine to yours. At a guess, you'll get to 160 MPH down park straight on the 748SP as long as get Charlies 2 right. Use that speed and suit gearing to hit a couple hunderd RPM below the redline. Also turn up the idle to about 2500 RPM. No reason why you can't hit 1:45ish with that. |
