I am hearing rumors that putting the F1000 gear in a F8 really wakes them up. I was told not to do this from D&D because that gear at 7850 rpm would run about 140mph(which ofcourse wouldn't happen). That gear is suppose to run 7200 rpm or so, but real world, real people answers is what I am looking for not some one trying to sell me $850 worth of junk that will make me go 1mph faster but take longer to get there ( sorry for the venting there). Has anyone done this? pm me if you want, thanks guys.
