and I am not sure if this isnt for the Manual!Netherless,your 9.6 is way off!I know you have bigger wheels but theres still a big difference!
Could the 4.4 mufflers be slowing your car down?I am just trying to help because you sound disappointed and I am appreciative of your feedback.
The main reason why my exhaust project is taking longer than I wanted is because I need to open both mufflers(3.0D and 4.8)and study/change the internal piping to ensure that it isnt obstructive.Like you and a lot of us,we all want to have our exhausts exposed and our primary objective is not to gain power but not to LOOSE any!....
How do you compare the performance of you new X5 with the other one you had??....In theory a 184 bhp x5 "tuned" should have +/- the performance of a 218 bhp 2005 model.A 2005 "tuned" should really fly........THANKS for the feedback.  |
The 8.3 is for manual with 235 tyres. I have an auto box and 315 at the rear. Plus I think that the bmw tests are done with standard equiped cars. If you have a fully loaded X5, then I guess you're at least 100-150kg heavier. And it's also the best run they did. I raced a few X5's and and always stayed foot with them, so I think it's normal (prior to putting the acs module). I will ask my dealer tomorrow whether the 4.4i pipes are more restricitive on the diesel. I might schedule a run on a testbench to see what the situation is. Also, my car has now only 11K on the clocks (5 weeks of ownership) so it's quite new. Maybe it needs to loosen up a bit.
