I have recently aquired a VS commodore borg warner 8 3/4 inch limited slip diff for use in my TA22. Stock they run 3.08 ratio. I have access to the following ratios 3.45, 3.5, 3.7, 3.9 and 4.11. I was thinking a 3.7 ratio would suit my car (3TG, W55). Although this ratio (pintara) has a harmonic noise at about 86kph, not a problem, just a very closely matched crownwheel/pinion design. My mate who is modifying the diff reckons 3.45 would be the go.
How can I calculate the rpm that the car will do at 100kph (205/45/16 tyres)?
What ratios are other people using and why?
The car will be mostly used on the street, with occasional drag racing.
