I recently purchaced a 97 540i and i love the car but it's bone dry stock with the exception of a K@N replacement filter.I don't have a tremendous amount of money to spend but i've done some research and i was wondering what anybody thinks or knows about those 1 psi electric superchargers they have on myhotbimmer.com?they have them on that website under intakes. I also was wondering if anybody knows anything about those aftermarket performance chips by SCL or SLC performance (or whatever)? They claim to give up to a 50 hp and a 6/7 mpg increase for only like 70 bucks!And then of course there's cold air intakes but for the same price as that electric supercharger.And then there's exhaust.What is my best bet?Thanks for your time and consideration, 540 Aaron
Sorry mate, there's no way to make a 540 go faster for cheap. I should know.
Your best bet is to save your money and get a Dinan supercharger. They have come way down in price and are now roughly equivalent to VF Engineering's prices, except more reliable with better customer service.
If you are going to increase power, you also need to upgrade suspension and braking.
How did you unlimit it ??? as here in europe they are limited, as this was the limit speed on the German Autobahn's. Ah, but you are US MPH and I believe there is a difference between US & UK MPH?, maybe this is why youve gone past 155 on your clock ??
EDIT : No just found they are the same its only land measurement and MPG that you get a difference.
So the question remains: How did you remove the limiter???? Love to know as thought they were it the gearbox somewhere??
