What type of setback are most of you XR-01 owners running say with 300plus HP, for pure drag race, not lake runner.
How bout propshaft height?
Thanks, Russ

keep it close. 3-4 inches. spread your weight around, not just all at the back. the shorter the distance the lower you can go. start 1/4 below and work your way up. The nice thing about that boat is if it's to low it will tilt to port. To high you'll have tons of steering torque and it will "drag" the bow at sub-light speeds.

Set Back
THey come from the factory with a 6-8 plate, with that said we tried it at 6 them moved it to 8, i didn't like the way the boat handled at 8" so I moved it back to 6". I was running about 1/4" above with a 300.

Thanks Randy and Rick. !

RB,
The quickest 2001 around here is running with his engine bolted smooth to the transom---how much offset is that? He's no slouch either at 8.5 sec, rope start. This boat had all kinds of plates on it for it's first two years and the closer we got the better it ran/handled. Of course other, trial and error, stuff needs to be done when moving the offset.

Rick,
I once tried to figure that out. They run a flying start so if your good your hauling the mail at the start when the timer goes. I suppose it's like the old clock start circle races.

I run both KDBA and SLDBA which is a 125' start, Jim Dunns hydro runs high 8's so I can only imagine how tough it would be to drive an Ally that fast. Jim runs mid to high 120's when he runs 9.00s. To run 8.5's you have to run over 130 I would guess, just never seen it at the rope races. Jon Wrights Tinker Toy on TONS of spray has run low 8s in the 1/4. THe guys running 1/4 masters on spray run hi 8s.

the plate gives you a little more positive trim, but it also takes away from the negative trim. you need it or wedges when using the short trim ram since they don't have quite enough range.
the 33c cable is for my trim limit switch. it lets me trim to the exact same place every pass. trim computers are to inaccurate and never seem to trim to the same place twice. this way you can set the run time long and let the limit switch stop it or not run a computer at all. my right button is 24 up and limited and my left button is 12 without a limit

That's a nice limiter idea.... I'm interested in that as well..!
The drag hull I'm getting has some sort of 10" plate on it now, but the guy had a 4 cyl OMC using it for roundy races. I'll probably opt for the Bobs manual plate with the 5" setback with 6 degree wedge.
Got some info for the trim limiter cable and switch?

Rick,
You are right the boat is 100% white and the previous owner (the one we worked setup with) was Dwayne Meeks. Don't know the new owner.

I thought it might be Dwaynes boat, I saw it run low 7s at SITC a couple years ago but that equates to hvery high 8s low 9s in the 1/4, 8.5 is awsome, I'd sure like to see it.
