Rear gear question
3400#
440”. 1.80 1st gear 4.10 rear 28? tire. Car isn”t performing to expectations. Only running low tens @ 133. 1.45 60? Think it needs a lower gear? |

Re: Rear gear question
Well, that would depend on your finish-line RPM. Just looking at your dyno numbers and not knowing much else, I would probably gear it to hit the FL at 7000/7200. But that's a Stocker guy talking. That would to me be conservative. Not knowing what's in your stuff.

Re: Rear gear question
Can’t read the graph. At what RPM, does it make peak HP and peak torque. What does your converter flash to and fall back on the gear change and what RPM are you shifting at?

Re: Rear gear question
Peak HP, 6700
Peak TQ, 5300 1.80 1st, it's gotta be a PG.

Re: Rear gear question
For optimum ET, If it was mine, it would have a converter that flashes to 5800, I’d be shifting at 7200 and gear it so it’s crossing the stripe at 7700. I would also get a 30” tire under it if you can not go wider.

Re: Rear gear question
If you don’t have a data recorder get one or at least a playback tach so you have real data. That said, definitely needs more gear

Rarely does more gear hurt! Depends on what your wallet can stand.
