Subject: Anyone purchase aftermarket cams? From: Dat Quach Date: Thu, 7 Dec 2000 11:58:03 -0600 X-Message-Number: 1 I was wondering if anyone has aftermarket cams installed on their M3s. If so, what problems have you run into if any at all. Also, what were the performance gains.

From: Dat Quach Date: Thu, 7 Dec 2000 16:36:59 -0600 X-Message-Number: 2 Instead of having one hole on the manifold for the air to exit, their are six individual throttle bodies to take air in. With this comes the Euro HFM, throttle body I'm not sure about. Their exhaust is also less restrictive since their regulations are less stringent. Even with all the differences between the US 240HP model and the 280HP Euro model, I've heard that the 280HP model only pulls ever so slightly from the US model.

Another question. Since our American M3's are "only" 240 hp yet the euro cars were supposedly 40-80 hp more, aside from the computer chip (which appears to add only about 20hp using aftermarket chips here in the US) what other differences are there between our cars and the euro cars that result in the additional hp? I have heard that the euro airbox makes only minor difference. Is it then the cams or compression ratio? Or, does using the euro computer chip make a greater difference?

From: GA - Robin Sun Date: Thu, 7 Dec 2000 14:41:03 -0800 X-Message-Number: 3 Correct on the performance difference, the US M3 torque is about the same as the European model and most of your daily driving needs requires torque. The individual throttle body on the euro M3 provides a faster "vortex" when the throttle is opened, in turn creates more vacuum pressure and allows air/fuel mixture to enter the cylinder faster. (In layman's term a fancy ram-air effect)... Which all in turn creates more horse power.

The biggest differences are: - 6 individual throttle bodies with individual fuel mapping for each (most of the HP gain). - Different cams? - Less restrictive cats (the rest of the HP gain) - Bigger Airbox, snorkel, amd HFM > Even with all the differences between the US 240HP model and the 280HP Euro > model, I've heard that the 280HP model only pulls ever so slightly from the > US model. From what most have said, that is correct. The US model was designed for maximum torque and power below 100MPH. If you look at the dyno charts for a Euro, most of the bigger power is up at the high-revs and at very high speeds. That's also why they get a 6-speed gearbox. Of you do the usual tuning tricks to the '95 - Intake/HFM/Chip/Exhaust, you'll see about 265HP. Add headers and bigger injectors and you'll eke out a few more. Not too shabby, especially when you realize with your horsepower coming up, torque does as well. -peterg '95 Cosmos M3 ECIS intake/Euro HFM/JimC Chip/Big Injectors/Exhaust --> can make my tires chirp in second _and_ third with a hard launch. ------------------------------------------------------------------------------------------- This message was sent using HiSpeed Technologies Webmail. http://www.hispeed.com ---------------------------------------------------------------------- Subject: RE: M3 euro individual butterfly throttle body integrat ion for US M3s From: Dat Quach Date: Thu, 7 Dec 2000 17:12:27 -0600 X-Message-Number: 7 Turner Motorsport has a set of the BMP designed ones for real cheap.
