Hey guys,
This is a strange combo, but have a hellcat tr6060 behind a 5.7l gen 3 hemi, running a 7675 turbo. Car weighs around 2750 with a 275/35/18 rear tire.
Gear ratio is
2.26
1.58
1.19
1.00
.770
.630
Was considering with weight if car and low end torque, going with a 3.55 rear. My tuner recommended a 3.73 or even 4.10. Car is a corner carver and just run machine. Sooner or later will make 1/2 mile to 1 mile airport runs but will probably need a rear gear change then.
I'm racking my head at the moment for a good gear ratio though. Thoughts?
