Ater i had several transmisson proplems. i realized that i need a stronger one. i decided to build a custom gearbox. so i can decide for ratios. what would you chose if you build one?
here is some ratios ......................Standart...................fensport.............custom 1 st gear......3.38 - 57 Km/h.............3.58....................? 2 nd gear.....1.91 - 100 Km/h...........2.045..................? 3 rd gear.....1.26 - 150 Km/h............1.33...................? 4 th gear.....0.92 - 210 Km/h............0.97...................? 5 th gear.....0.73 - 239 Km/h............0.73...................? Final drive 4.285............................3.933...................? can any one tell me what is relationship between final drive and gear ratios. if gear ratio x final drive ratio is equal, speed is same. those are thinks that i am planning to have. *seq. Shifter *new input and output shafts, staright cut gears, dog clutches, hubs, forks *final drive (pinion and crown), front & rear *front lsd (not sure about front lsd, fensport is using stock one) This post has been edited by tufy: Mar 8, 2007 - 6:34 AM --------------------  |

If you mapped it at that boost... and it is NECESSARY to do that if you don't want an explosion of your engine  , you should even know those numbers !-------------------- Wolf_Tm (Parma;Italy) [Silat-Kali]
