In Reply to: Re: Supercharging-Turbocharging Questions (Long) posted by Bruce on October 04, 1998 at 15:11:31:

: : 1. The ///M Roadster has a large engine in a small space. This causes increased heat in the engine bay. That is why BMW redesigned the front end and took off the fog lights, to allow more airflow into the engine bay. It seems to me that more horsepower may mean more heat under the hood. Does anyone know if the motor runs hotter when connected to a turbocharger or supercharger? Is this a problem? If it runs hotter, what modifications should I make to the type of oil used in the motor?

: devon covered the brake duct issue...i would follow the manufacturer of the turbo or SC as far what oil to use

: : 2. Most turbocharger or supercharger changes also include a new computer chip and larger fuel injectors. What is the effect of these after market changes on the scheduled maintenance I'm suppose to received from my local BMW dealer?

: as far as larger fuel injectors go, some do, some don't- it depends on the boost...it shouldn't affect scheduled maintainence

: : 3. What is the effect of adding an after market turbocharger or supercharger on the new car warranties from BMW?

: if BMW can trace the problem you complain about back to the mod then they won't cover it...if the problem is unrelated they should cover it

: One maker of a turbocharger and supercharger posted a web sight note that indicated that it does not void your warranty.

: which manufacturer? I doubt somebody would make that claim

: I would rather avoid the legal arguments with my dealer and BMW. What I'm looking for is this, how has BMW actually treated a warranty problem with major after market modifications to their motor?

: again if they can trace it back to the mod they won't cover it...end of story

: : 4. Dose anyone have any thoughts on whether a turbocharger or a supercharger would work best in an ///M Roadster? A recommendation on the brand would also be helpful?

: i have seen some turbos for Z3s but none for an M, mostly SCs are put in....I believe it is George Boyce who put in an ERT SC in his M that he had at the homecoming, also there was an article in the Roundel a couple months ago about a guy who put one in his M...if it were me i would go with ERT over Dinan due to JimC being involved in the engine management changes in the ERT model...just my opinion though, i am in the minority here when it comes to JimC vs. Dinan, but i am in the majority on the Digest

: : 5. Should I wait until the motor has a few miles on it before I install a turbocharger or a supercharger? By this I mean, should I wait until after the break-in period is over or until I have about 10,000 miles on a well broke-in motor? I should note that my Nissan 300z turbo came with the car, and I have had no problems with it in a little under 100,000 miles.

: i have seen one and heard of one other M that had an SC added from basically the beginning, but i haven't heard about any problems

: : 6. I note that Dinan sells a Supercharger System for $6,995.00, says it takes about 21 hours to install, and makes 338 horses with 281 ft/lbs. of torque. Dinan also offers a Supplemental Warranty for $2,500.00. Turner Motersports sells a Supercharger System for $5,995.00, says it takes 7 hours to install, and makes 356 horses with 302 ft/lbs. of torque. Does anyone have any experience with either one of these systems and do you have any recommendations?

: like i said above, i would go with the ERT SC (the one turner sells

: Why is a Supplemental Warranty needed anyway?

: b/c the BMW warranty (engine and powertrain, or anything else they can link back to that mod) is VOIDED no matter what any manufacturer of a turbo or SC says
