I've got a gigantic titan worth of BHP strapped to this car and parts fitted and I'm having a couple issues dialing in the gear ratios. Fidgeting without knowing what I'm doing helped me drop from 204MPH to 154MPH and I'm down to learn gear ratios for different situations. At the moment, I just want to learn the math behind gear ratios and how I can get the most speed out of this stupidly powerful monster.

Feel free to post your monsters and setups and let's get a compiled thread of ridiculously powerful cars tuned to a DRIVABLE standard!
 
Ive got an absolute monster of an R33 Skyline GT-R Vspec for ya.

Racing Soft tires front and back
Racing Brakes
Normal brake Controller
Racing Suspension
Medium Stabilizers front and back
Tuned Cpu
Spec 4 turbo
Full race Drive Train, muffler, and intercooler.

Pumping out 941HP and 260MPH on the oval.
When going around any other track its like tokyo drift in the corners.
For the actual tuning part i didnt touch the suspension or aero, just the gearbox.
Ratios are as follows.
1st: 2.831
2nd: 1.697
3rd: 1.212
4th: 0.919
5th: 0.632
Final: 3.537
I have no idea on the actual science with gear ratios, transmissions were never my strong point in the shop. But i spent about a week fine tuning this car, and ripped through most of the game with this set up. It takes a little getting used to driving, but once you do nothing can keep up with it.
