That's another reason I'm going to wait a bit. I have no idea how long-term reliability is for a supercharged M54 engine. The ESS unit only creates 6-8lbs of boost, but over a long period of time, the extra pressure might cause long-term damage to the engine. And instead of paying the $2-3K for ESS's 2-yr waranty, I think I'll wait the 2 years to see how other people's cars are holding up.b8hs said:cos i dont want to blow up my car in the process of it.
What do you mean? A 330CI and 330i have exactly the same engine.. what performance options do coupe buyers have over non-coupes other than the option to buy an M3??Nick325xiT said:Supercharging a 330Ci is very expensive. The total hit you'll take after voiding your warranty (or paying the premium for the ESS one), the reduced resale value of your car, etc. is very likely to either equal or approach the cost of an M3.
It makes, IMHO, a lot more sense on, say, a 330i, or a 325iT, where there are no options for increased power. You coupe people have a shitload of OEM options. Take advantage of them. (Yes, I'm jealous. I'm still irritated that I couldn't buy a 330xiT.)
centrifugal blowers won't even begin to reach 2psi until you're well into the midrange of the rev band. and so the peak 6-8psi is rarely used unless you keep your engine at 6500rpms all day.
