Is there anywhere to find 0-60 and quarter mile performance of a supercharged 4.6?
Thanks in advance for your thoughts.

Hi BC, SeattleYates logged a gtech 0-60 time of 5.2s, details can be found here:

There aren't any recorded 1/4 mile times that I've heard of, so I'm going to bench race for a minute. Bear with me... feel free to correct if I'm off...
~4824 curb weight (spare tire, tool kit, everything)
~149.15lbs of curb weight is fuel (24.56 gallons of fuel @ ~6.073lbs/gal)
(Let's say we race when the reserve capacity is full, in other words, when the gas light comes on: ~2.5gal@~6.073lbs/gal is ~15.18lbs of fuel)
Subtract the difference in fuel weight (-~133.97lbs) and we're at ~4690.03lbs
Driver weight for this instance is ~190lbs
Race weight is ~4880.03lbs
(Peak) Power is ~451bhp
I would bet a few dollars that the time would be very near 13.5-13.6 @ 106-108 mph Maybe a tenth or two faster, given the Si-Trim impeller blade, more area under the power curve. That coupled with the performancegearing 4.44 front and rear differential gearsets would have us knocking on the 12-second door.
As far as expense justification, that depends on finances, which are none of my business.

disturbedk24, just wanted to clarify, is 01blacks4 your old username, or did you buy the Dinan X5-S3 from him/her? Good to hear that another found this thread!
