Just a guess that a -1 would be fine I would think a -2 would be hard to get on plane.

Yes you can change the lower part of the bravo drive -1 inch or -2 it will help give you more speed.

Get a minus 2. You can always space back to standard. It's not cheap, but less costly then two lowers.

There is no tried and true answer to your question. Props make a huge difference on the mix as well. Start methodically with a prop that works, then move onto fine tuning up or down with the drive. Time and money is all it takes to go fast. Ask me how I know!

Good luck,
Dave

I have a XR/-1 right now, friend is selling a -2 lower. I will just have to try and find out. According to Formula, the 1998 271 Fastech has a 18" X dimension
