How do you calculate first gear ratio?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).
Can I look up gear ratio by Vin?
While it may be possible to derive information about an auto’s gearbox ratio from its VIN, that depends largely on the information the manufacturer includes in the vehicle descriptor section (VDS) of the VIN.
How do I tell what gear ratio my Chevy VIN has?
Identify your GMC or Chevrolet rear end gear ratio by the RPO Codes, usually located on the placard labeled “Service Parts Identification” inside the drivers door panel or glove box.
Will 4.10 gears make my car faster?
Most late model Mustangs and many other sports cars come equipped with standard 3.55 gears in their rear differential, however by adding 4.10 gears they can effectively make their drag times faster and deliver more power to the wheels faster.
What’s the gear ratio of a first gear set?
The first gear set is 30 over 10 or 3 to 1. And that the ratio across the second gear set is 40 over 10 or 4 to 1. This information can be used to determine the ratio across the entire series of gears.
What’s the rear end gear ratio on a Fox?
Coupled with the factory rear end gear ranging from 2.73:1 to 3.27:1 depending on trim, the automatics are more get-up-and-go compared to the manual equipped cars. Even then, the manual equipped cars are leaving a lot of potential on the table with their high factory differential gear.
What’s the gear ratio for a 17 tooth clutch?
Notice that if you make an uneducated purchase and decide to go with a 17 tooth clutch bell and a 62 tooth spur gear you end up with the same gear ratio (3.6 and 3.6 is stock). So your truck’s performance is not going to change at all. It pays to do a little homework.
Why do I need to lower my gear ratio?
The 3.07:1 differential with the close-ratio gearbox raises second gear so much that the engine will be “bogging” coming out of the slowest turns—and you don’t want to downshift into first. This gives us another reason to lower the 3.07:1 differential ratio. (Remember that lowering the ratio produces a higher number.)
