Hi Jim,
taa for getting back to me. You have answered a very important question for
me. I had been wondering if indeed the SB-3 may actually be a bit too wild
now, as I do need the car driveable at lower revs, to get to and from
events. However, lack of power at town speeds will gladly be sacrificed for
power in race/hillclimb situations. I need it to be producing good torque at
3500 and will prob rev it to around 6500. From what you say the SB-3 should
be fine.
taa again
Greg
