canedkydd Member 56 Member For: 3y 11m 2d Gender: Male Location: Wellington New Zealand Posted 21/05/20 09:16 AM Share Posted 21/05/20 09:16 AM I see some pretty impressive numbers posted. question I have is what ratio diff gears are you running ? and why ? I have run many v8 cars down the strip and understand the advantage of say a 4.11 ratio diff but I am new to turbo cars and the boost and torque curves they produce. any advise greatly appreciated.

I've done a 1.99 60ft, launching in second gear on the road in my fat arsed territory, so a sedan should have no worries going quicker on the strip. So yerp, ya need more power.

If I can hit 1.99 60ft I will be stocked as that will mean I will deff dip into the 12's Link to comment Share on other sites More sharing options...
