Polo or Velociti gearbox for quarter mile???

[SUM DP-GP]

hi guys

i have a question, the car in question is a 2L 8V turbo. which of these 2 boxes would be ideal for the quarter mile? @ the moment there is a 2Y box, think its the 2L 16V box. I was told now to think of putting either of these boxes, which is better from all 3???

in my opinion and experience the Velo box is best hands down! the versatility of the velo box is far superior to the more sluggish polo boxes (in my opinion ) although the gear ratio on the polo boxes are more suitable for a better top-end, it depends on what your finishing time and speed is at the moment! if you are at the 145km/h mark then i would say go for the velo box as it will be more suited to help deliver max power in that range, but the polo box will have a slight advantage if you are finishing in 155km/h + region. i have always enjoed the velo box and know of some rally polo's here in RSA that use it (obviously with different fdr's). how much torque are you pushing out ?
