I'd be interested in the thoughts and theories from other board members regarding the tested quarter mile times for the E55. In some of the initial automotive press testing (MY'99), 13.4/13.5 seconds at 105-107mph seemed consistent. In later comparison tests (MY'00)with, for example, the XJR, the E55 turned in 13.9 seconds at 103mph. Up to a 1/2 second disparity is generally regarded as significant for the 1/4 mile. Any theories on the difference? Could it be the '99 model year v. the 2000MY? Thanks.

Also, elevation is another variable.

E55 performance discrepancies

I purchased a 99 E55 and ran my own tests at a drag strip and 13.625 @ 104 mph was my best. The temperature and humidity had a substantial effect.
This year I took delivery of a 2002 model and achieved a 13.467 @ 104.3 mph. Given the high ambient temperatures(90+) when I made these runs I believe they could easily have been a tenth or two quicker in cooler weather.
Now if you really want performance, call RENNtech @ 561-845-7888 and ask for Bob Brady or Hartmut Feyhl.
My E55 is now upgraded to 500+ HP and runs in the 12.2 second quarter mile at 116 mph on street tires and in 90+ degree weather. These guys know how to get it done.

going faster

Hello Bob,
Temperature and humidity can make a huge difference in performance, 11 degrees f. = 1 hp does not sound like much. but factor in under hood temps and all of a sudden things change alot. If going faster is a priority you may want to check out www.kleemannusa.com. Thier supercharger will take an E-55 to 562 hp!!!!! Thats what I call a case of corruption via power

renntech upgrade

How much was your renntech upgrade (round $)? How much time did the upgrade take and what were the logistics?

Thanks,
Alan

Supercharger Reliability Concerns

Supercharging is definately a no nonsense way to achieve a bigtime increase in performance for an already outstanding car, the E55.

Several posts though, suggest that while the superchargers themselves are very reliable, the other peripheral drive line components in the E55 may not be up to the additional HP produced by the charger.

Curious to see what others have to say, based on experience.
