If it is that slow it is either worn out or way, way overdue for a major tune and service. FYI a two ton car with a 4ltr engine is never going to win a drag race. The only way to combat that is with a lower diff ratio which will louse up your gas mileage. The other way is to trade up to a 760 - factory fast.

100% agree.

If you want a really fast 7 you'll have to do an LX7 swap or something like that (2JZ, RB26). A superchager is only gonna put you at 400ish(10.5lbs per HP). To make a 4200lb car really move you need upwards of 600hp. This will give you a HP to weight ratio of 7lbs per HP(anything below 10 your really starting to cook). I had a car in Japan that was 7 something lbs per HP and it ran 11.65 @ 118 in the 1/4 all day long. I also had a superchaged 540i before and I was not impressed. Superchaged 7. Cool fator is up there but it would be like putting a 200 shot of NOS on a 1974 Ford LTD station wagon, whats the point.

My 740 has 95K miles and runs very strong. If i turn the DSC off I can sit there and white smoke an intersection until i have no tires left. If I want to pass someone. No problem. barrier my foot and before I know it im doing 100mph+. The car does move pretty good for its weight, but you trying to piss on a forest fire. If you want something that you can make really fast for really cheap try a 1994 (best year to get) Mitsubishi Eclipse GSX. You can have a high 11 to low 12 second car for about $5000, if you have the skills. You'll spend more then triple that trying to get a 740 into high 12's low 13's.

Not trying to rain on your parade, more power to you. I would love to see a full interior 740 run a low 12 in the 1/4 mile. Go fast with class. For most people buying a used 740i, we just dont have the funds to make these things move like that.

Goodluck to you.
