Hello! For all 928 owners, please help me with something here.
I am close in getting a 928 but friends and family tells me that is not worth getting a 928 because is a V8 engine and it will swallow gas like crazy and parts are highly expensive. They got that idea because I have a 2005 Dodge Durango and naturally is a V8 engine and I spend a lot of money in fuel for that SUV. My theory is that the Porsche is a light car compared to the Durango and it wont spend as much gas compared to the Durango. They say that is not true so I want to hear it from the 928 owners how is the fuel economy of the 928???
Does it really swallow a lot of gas?
Can I use it for daily basis or only as a weekend car?
Is it true that if I install a supercharger will increase fuel economy?

More so than my 912, 914 or 931... but its a very good engine my old 928S would get about 18 mpg on the highway
Can I use it for daily basis or only as a weekend car? If you are not going to far, yea use it daily drive it, have fun with it!
Is it true that if I install a supercharger will increase fuel economy? YES, you are sucking in more fuel, and unless you want a speed thing, I wouldn''t do it. If you do go with 928 Motorsports for the parts.
And parts of the 928 can be a bit on the high side, but Mark over at 928 International can get what you need for it.

15 mpg is average.
Supercharger will not increase fuel economy. If anything it will reduce it. Also, at 5000 - 10000 just for the equipment, well, that''''s a lot of gas, even if it did increase the fuel economy.
"Although roots superchargers have significant parasitic load and do dramatically decrease fuel economy, centrifugal superchargers will yield approximately the same fuel economy as normally aspirated engines, under normal throttle conditions. When racing, however, fuel enconomy will decrease given the supercharged engine''s ability to consume additional fuel and produce additional horsepower." -
