Can a 67 Extreme Roadrunner be improved enough to run with a Crapshooter or SGX?

Tim,
They sure can run with anything out there. Boat set up is everything.
Testing your: motor,pipes, and propellers should get you very close.
We have found that a little looser front sponson setting to be the way to
go with most of our boats. 4.1 degrees on the left and 4.3 degrees on the
right seems to work very well for our boats. Refine the turnfin and push
the sponsons out 2" more than stock and you should be running quite well
out of the pits. H-32's should get you there once you get your motor burning
all the Nitro. You may want to play with the ride height of the tub a little bit
and possibly run a touch wider rudder blade. Hope this helps you to get in
the race with your boat.
Have Fun Testing,

Thanks Mark, I am on Ralph's list for a boat to be built. Is there anything I should ask him to do? Also when you say widen the front stance by 2" do you mean overall or 2" on each side.Are you familiar with Randy Sampson's/ Propworks props? He did a 1662 for me that was awesome .
Thanks
Thanks
Tim,
Randy did some beautiful work. A 1662 should work well also.
The 2" is from the tub out to the inside of the sponson. We tried it
on a few boats recently and it made them much better in rough water.
(2" on each side) I would go with the G-10 sponsons and ask Ralph
about the tub height getting increased a little more.
Thanks For Reading,

Thanks again Mark , I think Ralph is already increasing the tub for more fuel capacity. Also if your interested I could send you the numbers from Randys props for the 1662 and 1655. They both seem to make about a 5-7 mph improvement.

The question you need to ask is can I purchase the same motor packages that are in the other boats???
The current 2011 Road Runner 67 boat is more that capable of running with ANY boat in its class. The motor/pipe/prop have proven to be the difference. Not all the fininsh work in each individual crapshooter or SGX that you see running is created Equal
