CooperSAZ said:I plan on getting the Milltek exhaust for when my MCS arrives. The engine is rated with 5 additional bhp, which is due to a newer supercharger and some exhaust modifications. I guess the question is... with 168 bhp on tap, what will the new Milltek add? If it is only capable of adding 5-7 bhp (as opposed to the 8-10 it is supposed to add), then we will know how much the new "exhaust modification" on the '05 MCS is good for.
With respect to the warranty, an exhaust system should not be of concern. While it depends on your dealership, the technical terminology floating around at the dealerships is, "if the addon has a direct impact on the vehicle's problem." With that said, an exhaust system does not touch the engine directly, it only directs the exhaust gases to the rear of the vehicle. My MA said that a CAI and exhaust will not void the warranty. With the pulley, obviously, it will void the engine warranty. My $ .02.
Actually, the supercharger has been changed to a newer generation Eaton blower.dgszweda said:CooperSAZ,
The increase power is due to exhaust modifications, and ECU modification, not from a supercharger. This is the same supercharger as was in most of the '04 MCS's. I think you will get minimal gains from a new exhaust. Most of them contributed very little hp and probably even less now with the new power come from the stock unit.
Yeah but the 5th generation Eaton blower has been on the 2004's since at least January of this year, so that didn't contribute to the power increase between a June build and a July build.Paul Mullett said:Actually, the supercharger has been changed to a newer generation Eaton blower.
I wasn't aware of that, is that from experience? As that's not the story from MINI officially.dgszweda said:Yeah but the 5th generation Eaton blower has been on the 2004's since at least January of this year, so that didn't contribute to the power increase between a June build and a July build.
