yeah, i did... i got a gearset, and i tested the 3.0 with all the gears, the 12:1 being the most reliable, but it's so mother-torquey that it spins out far too often... it is about on par with a 2.6 geared with speed (teal) gears... except the 2.6 accelerates much slower...
im gonna lube up the 8.25:1 gears and see if the 3.0 wants to use them...
thx for the tip arceeguy!
