Re: Rear gear question
Let’s not! Start another thread about meaningless DCR. Meanwhile this thread is about rear gear, more of which the OP needs.

So peak HP is @ 6700 RPM and he said he is crossing the strip @ 7100 RPM. So just how much rear gear would you like him to run? As I, and other have said he needs a 3 speed trans. Stan |

Re: Rear gear question
So...
Stupid me is going to throw this out there... Peak torque is at 5300... It makes plenty good torque for a 3.75" stroke... If it falls to 6200 at the gear change I'm going to say you're leaving some power on the table... I would think if you send dyno sheets to someone like Coan, they could dial you in... May find you can tighten it a bit? I think maybe play with the shift point... As in higher... 7200? maybe more... See where it slows down... More gear would help, as would a 3 speed... If it crosses 72+ it really doesn't matter if the motor doesn't self disassemble... (don't know the parts or build) I see things I might try if it were mine... Depends on your budget really, converters/transmissions aren't cheap these days... Any way just a few thoughts from a dumb ol' Texas boy... Maybe some of this helps... Maybe it don't... As they say... "Your mileage may vary" |
