i would say it depends on if you have a stock or modded engine
i have basically stock but big exhaust and extrators so i would have lost a little bottm end and gain top end so the diff helped bottom end heaps as now its got the power to actually spin my new 235 18's my old 1/4 time was 16.1 @91 so top end was pretty fast for that slow time so my take off was very slow but now i can feel its so much quicker but haven't had the chance to test it yet but it kept up with a BA xr6t which was supprising but if i could guess i would say very low 15sec quater...so about 1 whole second quicker i will post up my next run when it happens |

if you know your sitting on 2000 rpm at 100km/hr, then the easy way is...
2000/3.45x3.7=2144 2000/3.45x3.9=2260 2000/3.45x4.1=2376 so lets just say you will be sitting on 2400 with a 4.11 ratio

Does anyone happen to have the ratios of a BTR 4 speed auto? Googling and car forums doesn't seem to turn up much.

Pretty sure they are all the same. That was from the FPV site, in the heritage bit.

My car seems to have lost a bit of power now, it cant chirp the tyres, even stalled up what could cause this problem.
