Guys..what do you think.If I hold second gear to 6500 rpm in second gear,then what speed will achieve? I have 4:11 diff ratio.

The calc is a bit off. I have done 3rd gear at 97mph crossing the line.i estimate rpm at 5200 in third.
Dazzler.No worries mate.I need a limiter of 7700 rpm to achieve the same.

depends on tyre height,not just printed measurements, but wear also, if auto you will also have to factor some slippage front the convertor

just a note. All convertors have a percentage of slippage, which is why late model convertors have lock up clutches, but these clutches are normally only applied at light throttle.

Can we change 3rd gear in the auto gearbox for a more aggresive response?
I think 3rd gear ratio in the box is not that toey.

The ratios are easy - straight from the book. Accurate tyre revolutions is tricky. The way I do it for greatest accuracy is to place the car on a level concrete drive and mark the bottom of one tyre with chalk and also the concrete at this point. Then drive forward exactly one wheel revolution and make another mark on the concrete - note the distance between the two marks eg 1850mm which is 1.85m. Divide 1000 by 1.85 and the answer is how many revs your wheels do per km. Then you can use this formula to calculate ... km/h per 1000 rpm = 60,000/wheel revs per km/diff ratio/gear ratio An example ... Given a diff of 4.1:1 (your diff); gear ratio of 1.45:1 (2rd gear auto but not necessarily yours); 510 wheel revs per km. In the formula you have ... km/h per 1000 rpm = 60,000/510/4.1/1.45 which becomes 117.65/4.1/1.45 which becomes 28.69/1.45 which finally equates to 19.79. So at 6500 rpm the car will be doing 19.79x6.5 which is 128.63km/h Hope this helps. |

Heheh its tempting but the wagon still has street duties everyday..maybe when it becomes a full drag car.

A mate of mine had 4.11s in his AU and the speed limiter kicked in at about 129!
If you want fast 1/4 mile times with 4.11s use all gears!

That dam 3rd gear is too lazy!! these cars would be heaps faster down the 1/4 with a different ratio 3rd gear. 1:1 is just wrong for the job. No wonder the six speed auto boxes are thrashing us. Having a more aggressive ratio there is flogging us!! We need to be able to use the first 2 gears instead.

Hey Stav I see you want to achieve 160km/h in second ...
To do that you can work back through the formula to find what diff ratio you need. Say your car's wheels do actually turn 510 times per km ... then here's how your formula works for you:- Given you want to do 160km/h at 6500 rpm. The 160/6.5 = 24.62. This is how many km/h per 1000 rpm that you have to achieve with your gearing. So in the formula:- 24.62 = 60,000/510/1.45/diff ratio 24.62 = 117.65/1.45/diff ratio 24.62 = 81.14/diff ratio OR diff ratio = 81.14/24.62 diff ratio = 3.29 |

On the other hand if you want to turn the car into a drag only monstor then you will want to go for 160km/h in third gear ... LOL
24.62 = 60,000/510/1.00/diff ratio ... calculates out to a required diff ratio of 4.78. |
