Do you know the approx. increase in torque (from 165nm) & did you feel an appreciable difference in performance. I am assuming it's your car that had the mods?
Just wondering whether it's worth spending that sort of money if there is not much improvement in performance....
dont get too excited. if auto then the gains will not be as close as if on a manual. the box just eats up the gains.
if auto, just dont waste your time and money trying to gain a few extra ponies. the auto box in these things are dinosaurs.
Awww...c'mon, I don't know whether you have dríven an NB auto but the box in these is not that bad. As I said earlier you only lose about half a second compared to a manual in a 0 to 100kph run according to performance figures.
Of course manuals are more fun & I take your point about the auto box soaking up a lot of the gains for this type of mod. That's more or less what I was trying to establish before I spent any big dollars.
Thanks for your input.
yes i have dríven one.
but you are only judging 0-100 times. so you are only judging the gearbox when the torque convertor is in lock up mode. outside of lock up mode, it's like any other auto gearbox, slipping, increasing heat and losing effiency, waiting on sensor feedback and thinking about gear changes etc. it's a dinosaur box from the 90s with 80s tech in it.
but if you only drive the car 0-100kph all the time, then knock yourself out. you theory is perfect. but take it to a mountain or have to accellerate and decellerate a number of times. then well i think everyone reading knows the answer.
you've also gotta look at whether the power gains will determine whether you need to start modifying the torque convertor. small torque increases wont need modifying, but if you really wanna up the power like numbers posted within this thread, then the torque convertor will need attention also. otherwise you'll just have more slip, more heat and even less effiency than before modifying then engine.
everyone in this thread is quoting power numbers from a manual car. in an auto you are only gonna see half what they will see. decide whether the dollars they spent to get those numbers are worth it when those numbers are half as good.
