What do aftermarket Superchargers do to mileage?
If the new SL55 has such bad mileage (11mpg) because of the supercharger eating a lot of fuel, I was just wondering what Kleemann and others do to your mileage when you add their superchargers.

Technically, with the supercharger you shouldn't have to press the gas as much in order to reach the speeds you normally drive at, so you would get better gas mileage. Realistically, when I get my supercharger, I doubt that I'll be doing anything but flooring it!

What about supercharger longevity?? I mean how long is the life expectancy on these superchargers?? Does it last forever or what part can fail on these s/c??
P.S. Vic check your PM and your other e-mail.

Oops
Jam: Kleemann products are built very well. Their kits come with a 1 yr warranty. I answered your email concerning engine life already, but basically an additional 3% strain is placed on the engine, which is not much. However, your driving habits and climate need to be considered as well.

SC Milage
One of the primary reasons the MBZ SC engines get such poor milage is their static compression ratio. MBZ lowers to 9.0:1 in order to run "high" (1 bar, 14.7 psi) boost. The intercooler MBZ uses is not that efficeint, reducing CR is a saftey net the choose to use.
Leaving the CR at 10.0:1 is much better for the efficeincy of the engine. Controlling discharge temps is the key to running higher CR's. With a very good intercooler you can safely run "high" boost on "high" CR engines.
Gas milage is directly proportional to the amount you use the SC. Constantly flooring the pedal will result in poor MPG, melted tires and a large smile on your face. A rule of thumb is about a 1-3 mpg reduction in city driving, highway driving remains the same. This is once the giggle factor has faded- when the SC is new, you find yourself always mashing the pedal.
Kompressors should last as long as the engine. KLEEMANN Kompressors are fed filtered engine oil for lubrication. You change the SC oil when you change the engine oil. The manufacturer of the SC claims 10,000 hours at full load. Thats 416.66 DAYS at full boost/max speed with no rest periods. The SC is under full load maybe 10% of the time you drive (average). If you drove 24 hrs a day its would take 4166.66 days (11 years) before you meet the MTBF criteria. Certainly this is an over simplified, unplausable scenario.
Properly maintained, the SC should go 100,000 miles with no problem.
