I am not saying you can ignore towing, but If you don't tow much, would a 3.64 make even more sense ?
Depends on your driving mix.

I'm sure that towing played a role in the gear choices, especially 1st/2nd. You'll trash the clutch if the gears are too tall.

Personally, I like short, tightly spaced gears as long as I can get a decent highway gear. The X5 is actually geared fairly similarly to my E30 M3 with S54 swap.

Acceleration is not the only factor involved here. Cruising is as well. And the type of acceleration that I am discussing, is not wide open to redline all the time situations.

There was no need to discuss superchargers and detonation. This is a diff thread. That is why I didnít bring it up. I posted a video of a noisy E53 because, the op suggested I ride shotgun with him for an extended period of time to hear his M54 sounding off. I think the op is more concerned with the sound his M54 is making versus his gearing .

The taller gearing will give you better mileage at a constant and consistent highway speed. But, I donít leave my driveway in 5th gear. Thatís is why other situations are being factored in, hence the argument when not in top gear. So at the end of the day it certainly will make a difference.

If youíre constantly on the open road at highway speeds, with zero traffic, just cruising and you donít mind the loss of acceleration, then change the ratio. But if youíve driving in town, on the highway, traffic, stop and go, etc. fuel economy may take a hit.

The loss of acceleration and fuel efficiency in my opinion does not make sense. The manual 5 speed gearing is perfect for the E53. It gets the tanks ass in gear, literally. LoL..

Yep, me too. Now only if my E53 had your 8000 rpm redline.

Well the op needs to decide whether it is all worth it to try and quiet his buzzing M54. Some sound deadening maybe?

Iíll be sticking with my gearing. Thatís my plan.

I will note that new engine mounts might accomplish more of what OP wants than changing the gearing. The engine is a lot quieter when the mounts aren't collapsed. And if they haven't been changed, they ARE collapsed.
