Very interested for my 2006 4.8is

Any speculation as to what sort of 0-60 times the supercharger would yield for the 4.8is? I'd be especially interested in a Group Buy>

Thanks

Bruce

How well does the transmission, transfer case, torque converter, etc handle the added power of a supercharger? It seems to me the stock transmission is rated for a certain input HP/torque. Are most people installing a SC without modifying any other part of the drivetrain?

There is no data available for that, as this is the first SC for a 4.8is. Member J.Belknap has a SC on his 4.6, and it has reportedly been very solid, but that is a different vehicle.

Any updates?

I continue to be interested in this for my 2006 4.8is. I plan to get in touch with Motor Works West to see if this is something they can do. I'd still like to get a sense as to the improvements in 0-60 that can be expected with the ESS SC. Will we be able to stay close to the almighty X5M?

Thanks.

Looking at some published specs, a 4.6is with an ESS supercharger will increase the stock hp and torque to 445hp/460tq... good for 5.2 seconds to 60mph... (almost identical 0-60 performance numbers produced by a stock 2003 E39 M5, which is very impressive for a 6000lb+ vehicle!)

On the other hand, the X5M produces 555hp and 501Nm torque... (good for a whopping 4.5 second leap to 60mph!)

Impressive specs, yes! ...but the short answer is still NO; you will get spanked by an X5M!

Unless you change Headers and change diff ratios there is also option for you to throw out cats and put straight pipes, but I don't know about inspections.

Probably just a little bit better than those 4.6 numbers posted (still about a second slower to 60). e53 only weighs about 250 lbs less than X5M, and ESS stage 2 makes 480 (vs. 555). Would love to do this if I had $9k to throw away. Come on Powerball!

Instead of upgrading the 4.8is with the ESS supercharger for 9k$, how much would a conversion to a whole different engine cost (perhaps the S70/2)?

Exponentially more. Entirely new powertrain, removing all the awd components, etc.
