Diff ratio answer required
Need advice on what diff ratio I need for my new engine power.
I've been thinking 3.45.1
566 rwhp & 613 ftlb rwtq
Currently running 4.10.1 from my old setup
Running a 6sp T56
1st 2.66
2nd 1.78
3rd 1.30
4th 1.00
5th 0.84
6th 0.56
285-30x18 tyres

I know it's not a direct comparison, but I run 4.10's with a T56 and about 600 rwhp & rwtq on the 150 shot. Honestly I hate this gear with the nitrous, but it's perfect n/a.

Occassional drags, maybe 3 times a year
Generally street
I have just had my old LS1 516fwhp n/a taken out & this new engine in.
The cars gone in for a set of 3.73s this morning, I gave it a lung full in 2nd gear & something in the diff didn't like it.
Had to settle on what I thought would work best.
