hey , what horsepower increase might i expect from installing a B & B exhaust system along with a power chip from " turner motorsports " ? TIA , Dick > hey , > what horsepower increase might i expect [quoted text clipped - 3 lines] > TIA , > Dick It seems to me that you could find this out with a visit to the respective Websites. Unless you are going to track the car, I can't see any reason to spend the money on these things. The car can already easily exceed any known speed limit, and do it quicker than most of the other cars out there. thanks for the reply Jeff . i already know WHAT they say ! i'm looking for a REAL assessment from people who know . are you saying that these improvements do nothing ? i would find that rather hard to believe .

I would not say they do nothing, I would say that what they do is not very useful for a daily driver. If you wanted to race your car on a track (we all know that street racing is illegal, and none of us ever do things that are illegal) then you would realize a gain from these expensive modifications. If you climb in every morning and afternoon, plying the freeways of the region back and forth to the office, I don't think you will be able to appreciate the money you spent. For the record, I had a Jeep CJ5 that was carburated and had a 6-into-1 exhaust manifold. I paid roughly $3,000 for a Multi Port Fuel Injection system and a header. The gains were HUGE. The money spent produced both performance and reliability improvements that were significant. So, I'm not opposed to the mods, per se. I just happen to think that BMW builds a damn fine car, and the exhaust is tuned about as well as an exhaust can be, and the computer is programmed about as well as a computer can be programmed. Jeep, on the other hand (in 1981) left lots of performance on the table ... > "D." <wdst...@sover.net> wrote in message > > and the computer is programmed about as well as a computer can be > programmed. This is a particularly true statement. In older BMWs with OBD I, i.e., those build in the early to mid 90s, a "chip" actually made alot of sense because back then, BMW tuned their car for the "average" driver who used *regular gas,* i.e., 87 octane. So, adding a chip would tune the car for "super" gas, i.e., 91+ octane, and could extract anywhere from 10-50hp and 10-50ft-lb of torque. You actually noticed the difference. However, on today's cars, with all the competition from other mfrs like Nissan, Audi, Lexus IF, etc., BMW pretty much tunes its cars for "super" gas to maximize the power. Go to Turner's website or whereever you plan to get your parts and you'll see very little if any gains. Good Luck! thanks to both of you . you gave me the info i was looking for .

I think you will find that modern BMW's automatically tune themselves for whatever grade fuel you put in (87 - 95 RON) Go to Turner's website or whereever you plan to get your parts and you'll see very little if any gains. Good Luck! > "D." <wdstk69@sover.net> wrote >> thanks for the reply Jeff . [quoted text clipped - 12 lines] > are illegal) then you would realize a gain from these expensive > modifications. I want to elaborate on Jeff's answers a little. The E46 M3 has a _VERY_ highly tuned engine. In fact, they had a couple of early problems with bearings (poor quality control partly to blame) and the fact that it has an extremely high redline. BMW had to replace engines, and in fact lowered the redline - which results in loss of performance! Any replacement of the standard software on an M3 will very likely result in shorter engine lifetime, and is unlikely to greatly increase power and performance. Now, if you're willing to put up with the degraded life, you will attain a little more power on full-throttle acceleration, at the cost also of lower mileage and rougher running in all realms. Frankly, here is the opinion of _most_ of the posters here (there's a guy named Chuck Krieger ?sp that used to post here that codified it): "The best money that a driver can spend on performance is a performance driving school course." A good driver will beat an less-accomplished one in identical cars all the time. FloydR >> "D." <wdstk69@sover.net> wrote >>> thanks for the reply Jeff . [quoted text clipped - 35 lines] > > FloydR A good driver might even beat a less accomplished driver in a "better" car. I agree with Floyd on this one, instead of spending money on parts, spend the money on lessons. They will make you better, and they're fun. An M3 is already about as good of a package as one can buy.

Driver training. 2. Buy an M5. Messing with the EMU will result in him getting to his destination and the end of the car's life sooner. > "Floyd Rogers" <fbloogyuds@hotmail.com> wrote in message > SNIP [quoted text clipped - 22 lines] > Messing with the EMU will result in him getting to his destination and the > end of the car's life sooner.

The reviews I've read have come to the conclusion that the stock M3 is a better performance/price value than the Alpina B3, though if you want an uncontrollable brute, the Hartge H50 V8 is an option (though not in the US).

Ask them? And get it in writing before wasting your money.
