Standard length on the drives and I have the SC lowers. The SCX are so much beefier than the Xr's they look like a cross between the NXT's and Konrads. ?I only have a few hours on them so far so my fingers are still crossed but I am cautiously optimistic based on what everyone else has told me.
I don't have a good pic of the drives, don't mind the duck!

If SCXs hold up I will likely go that route along with my imco sc lowers. Now I need to make some bucks so I can switch to a stagger set up. I can't imagine leaving 5 mph on the table

I'll take TomA's numbers any day over OL banter

All you have to do is come for a ride. Tom's boat is very fast and faster than most but a SV43 OL does run 118-120mph with stock Mercury or Ilmor power. Tom you'll have to come north for a run as I dont think we'll be in AC this year. Any #'s since the SCX install?

As for comparing boats, yes any of the newer sit down OL's w/ 700s will give a run and probably beat me. But for an 8 year old boat.... I am doing all right!
Dollar for dollar, there is nothing that touches a ZRC.As for the SCX, I am not in a hurry to test the top speed. I have noticed no difference in speed vs. rpm through the range of 3500-4500. I had the props redone over the winter by B-Blades and that is skewing it a little too and giving me better bottom end. They did an amazing job! I can run 35mph at 2500 rpm and hit 60mph at 3500. By 4500 I am doing 85. I was running a fast idle of 1200 and the props started to aerate and the boat wanted to jump on plane. So far I am very happy with everything!

I've never looked into the Z's design, but what is it about the hull/setup that makes it so efficient for a deep v?Anybody ran Ilmor's in them?
