Extra BHP on the facelifted LT

[simon]

Recently bought an 05 LT with supposedly 15 more BHP than the old model.
The acceleration being (slightly) better doesn't mean much to me, however, get to 80-90 mph and roll on the throttle...BIG difference! You can feel every one of those extra ponies. Love it.

My 2002 has had the same/better performance since 2002 when I installed a Rhine West Performance Chip and fitted the Remus Header/Exhaust system!http://www.bmwlt.com/forums/images/icons/icon10.gif

Recently bought an 05 LT with supposedly 15 more BHP than the old model.I can't ever think of any instance when more HP and more torque is a bad thing. ;) Congrats Simon. :)

Does the LT lose some of it's power in the mountains like other bikes that don't have fuel injection? ......... :confused:

The air is thinner so the computer compensates for the different A/F mixture, thus the power decreases. But the advantage is that your mileage increases drastically. I enjoyed 57mpg on my LT when touring Colorado. :)

Thanks........I got about 5 mpg more than usual........ :)

The only difference between EFI and carborated engines in this regard is that the EFI will lean out the mixture and the engine will still run smooth (likely accounting for the increase in mileage), where as, an uncalibrated carborated engine will spit gas out the tail pipe as it chokes and coughs when the mixture is too rich.

All normally aspirated internal combustion engines that is!

Ah yes the Lure of Turbo Charging, Urr Super Charging, Urrr Turbo Super Charging, Urrrr Turbo Normalizing, Urrrr

O you get the drift!!!! That Dang Manifold Pressure will get you every time!!

That's funny! My Harley dealer told me the Harley had a carb in it because it "ran better in the mountains" :rotf:
