I have the 4.57 r/p and the .77 4th gear and wish I'd gone to a little
taller 3rd as well. The new Boston Bob motor with cam and headwork has
about 1k on it now, so it isn't totally loose yet, but my observations
climgin a long semi-steep grade on I-430 South in Little rock confirms that
the old engine and stock tranny would lose about 8 mph(70 down to 62), This
newer tranny ratio and new motor lose 18 mph (down to 52 mph) and although I
don't have the Haltech FI settings perfect yet and the Bob motor is still
not totally broken in yet, the gearing is more likely to blame than the
engine at this point.
Yes, I turn a whopping 3400 rpm at a true 70 mph, but that translates to a
really low rpm at 50-60 mph and this engine doesn't have the torque to pull
it on any grade. Maybe that will change as the miles acrue.
I have on more than one ocasion been driving to work on a flat 50 mph limit
road and glanced at the tach turning 4500 rpm because I was still in 3rd
gear! The motor is that quiet and it's pretty strong up there too.
I'll keep playing ,but for all the bucks I have in this thing, a TDI may
have been a better choice. Still not disappointed, but not ecstatic yet
either.
