Gearing for 4-link suspension
I would appreciate a little help understanding gearing and RPM change on a UMP modified.
We run a 4-link (clamped up) suspension on the LR, and spring-on-top Z-link on the RR.
We are running a 6.39 gear in a quick change rear end on a 5/16 medium-banked oval (those who are around West Central Indiana probably know where the only 5/16 oval is). At times, we turn as high as 8500RPM.
I was told that going up in gear (6.56) would actually LOWER the RPM.
Is this due to the taller gear getting up on the bar and driving the tire to the ground, putting more load on the engine?
Thanks in advance.
