Ya, I run 33" tires 5.83 gears, which bring me
lower than stock gears and tires. Add the weight
of the 2 door at 2500 Lbs plus me at 200 lbs and
150 HP engine with quite a bit more torque and
you have a monster of a ride, mind you I still will
have a challenge in the big dunes with the buggies,
but I don't have paddles either
So at 2700 Lbs I have about 18 lbs per HP, about the
same as a full size truck with 350-400 HP, and in a much
more capable package.
I expect to be getting about 200-210 HP from the new
engine and lower that to around 12-13 Lb per HP and
increase the dunability also

BTW 22" tires don't air down well, and the foot print,
is also a big factor, as well as tread pattern
