#1. Re: [E36M3] e36 vs e36 thermostat - from Ed MacVaugh

Date: Thu, 14 Dec 2006 19:57:07 -0500 From: Ed MacVaugh <macvaugh@comcast.net> Subject: Re: [E36M3] e36 vs e36 thermostat The goal of the thermostat in a modern engine is to keep the engine temperatures in a narrow band to enhance the accuracy of the electronic fuel and ignition management systems. It functions like the thermostat on your house wall, which attempts to keep the temperature of the interior of the home constant. The thermostat in your engine's cooling system tries to warm the engine up to operating temperature as quickly as possible. It does this by shutting off flow to the radiator at startup and opening to allow flow to the radiator gradually so as not to shock either the radiator nor the engine with a rapid temperature transient. An added benefit of the closed thermostat is that the heater core flow is on the engine side of the thermostat, warming the heater core water quickly in cold weather so that the interior of the car gets comfortable quickly. Going to a "cooler" thermostat will mean that the flow through the radiator will begin earlier in the engine warm up cycle, keeping the heater core water cooler longer and keeping the engine below operating temperature longer. It is analogous to setting your wall thermostat on 55 degrees fahrenheit and expecting your home to run efficiently with your family running around in parkas and attempting to spread solid butter on your bread. Assuming a properly operating cooling system under pressure, the cruising engine water temperature will be in the 102 degrees celsius range, 215 degrees fahrenheit range on a hot summer day. The water would boil were it not under pressure and mixed with coolant/antifreeze. The upper end of the temperature range is not controlled by the engine's thermostat. Once the thermostat is fully opened, full flow through the block and radiator is achieved and the temperature is determined by ambient air temperature, engine load and efficiency (spark retardation, and such), radiator size and water pump flow rate. One twist on this is the new engine's variable speed water pump in the E90 where the water pump is electrical and can change flow to use the minimum energy necessary to cool the engine.

There's more stuff out there for it than I know of... If you want it for street navigation, a friend of mine has a Garmin (can't recall the model number) that has audio and is great for traveling.

Has the 95 lifter tick. Other than that its in good shape. Synthetic oil it's entire life, after break in, bought the car from the second owner. As far as I know the head has not been off, not 100%, but pretty sure it's never been off. Comes with exhaust manifolds, dual mass clutch/flywheel, front crank pulley. No intake manifold. NO harness or ECU. $2500.00 (since it has lifter tick) (Plus shipping) I plan to put it on eBay after Christmas. Thank you, Gary Gray Pro Bike www.probikeusa.com

#10. The slippery slope continues... - from Jeff Conner

Date: Sun, 17 Dec 2006 09:07:54 -0800 (PST) From: Jeff Conner <jeff.conner@yahoo.com> Subject: The slippery slope continues... Actually, it's feeling more like a cliff. I just placed a depost on what will be the track car for myself and my wife. No more tracking the 98 ///Sedan. I'll be out there in a 95 that has already been quite well prepared.. If you're realy bored, you can check out the spec sheet and some pictures on my website: http://www.drumwagon.net/raysM3.html I'm thrilled to have a car that we can dedicate to track use. The thought of her getting better, faster and riskier in her 05 ZCP M3 and having an on track incedent either of her own fault or someone else's is not a good one. Wadding up a $55,000+ car on track and having the insurance company deny the claim would be a VERY tough pill to swallow. Even more so, as I'm further up the curve from her, I'm probalby closer to running out of talent. The safety of a cage - there's a TC Kline/HMS motorsport bar in the car right now - a full 6-point cage will go in sometime in the next 9 months (my guess, maybe sooner) is key. She told me recently, after riding along with me at an event where I was rotating my car on the apex berm of a 3rd gear turn (she was visibly scared the first time I did it with her in the passenger seat), that "you need a car with a cage. I want you to come home alive from these things." So, it boils down to both of us being infintely more valuable to our two kids alive than the extra $XX,000 in the bank. We're both pretty excited. -jeff 98///sedan ||| 95///trackcar __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
