OK, now I'm confused. The Z06 doesn't have forced induction. If the 2001 you rode in has had turbos installed, it for damn sure better have more than 415 hp, which is only 30 over stock for that year. But yes, even a bone stock Z06 is brutally fast. Neil 96 M3

#2. Mobile 1 Cured my VANOS rattle. - from DiVincenti, A.J.

Date: Mon, 28 Jan 2002 10:18:04 -0600 From: "DiVincenti, A.J." <ADiVin@lsuhsc.edu> Subject: Mobile 1 Cured my VANOS rattle. Check this out. Several months ago I had complained about the VANOS rattle. I noticed the noise only after I switched to Red Line 10 w 40 but didn't make the connection until after searching the archives. Others have noted a connection between with the oil and the noise. I had decided to live with the rattle, but when it was time for my next oil change I switched to Mobile 1 10 w 30. Here is the kicker - the VANOS rattle is gone! I can't believe it myself. Chester and I talked about this privately but we figured the damage was done. I was very surprised the rattle simply went away due to the change in oil. AJ

#3. brake fluid - from DiVincenti, A.J.

Date: Mon, 28 Jan 2002 11:06:35 -0600 From: "DiVincenti, A.J." <ADiVin@lsuhsc.edu> Subject: brake fluid I should have said 100% synthetic. Motul 600 is polyglycol based and should not be mixed with silicone or mineral based fluids. I believe ATE is mineral based and is compatible with "conventional" fluid. Not all brake fluids are polyglycol based.

Motul is a synthetic. Are some systems designed for non-synth?" all brake fluid is synthetic. polyakylene glycol ether is not found in nature, from coal tar or petroleum or any of the usual suspects.

#5. BMW Antifreeze only? - from McCarthy, Brian
Top
Date: Mon, 28 Jan 2002 09:53:12 -0800 From: "McCarthy, Brian" <Brian.McCarthy@intermec.com> Subject: BMW Antifreeze only? Greetings Everyone! I'm preparing to change the water pump, thermostat & housing, radiator, timing chain tensioner, etc. There's a cold snap in Seattle now, so I'm procrastinating until next weekend when my unheated garage oughta be a little warmer. In reading the procedures, most specify BMW antifreeze. Why would a BMW engine need a different antifreeze than what the rest of the other engines out there? Is there something special about BMW antifreeze? Can anyone make a recommendation of an "after market" antifreeze? (Seems like a strange concept - "After Market Antifreeze") Thanks! Brian McCarthy '95 M3, 27K miles, with original water pump. Soon to have "after market" metal thermostat housing.

#6. Brake Bleeding - from Robert S. Hatrak II
Top
Date: Mon, 28 Jan 2002 10:01:55 -0800 From: "Robert S. Hatrak II" <rob@hatrak.com> Subject: Brake Bleeding Last night I tried to bleed my brakes using a home-made contraption. I made an air hose that connects to my compressor. From there, the hose attaches to a brake fluid reservoir cap (the one listed on Jim Powell's website). Basically the same thing he does on his web site, except I didn't use a bug sprayer for pressure. All went great until I tried to pressurize the reservoir (with 25 lbs). This cap doesn't seal, and pressure (and a bit of brake fluid) leaked out all over the place when under pressure. What cap do you all use? I'd like to get this thing working so I can bleed my brakes, and maybe sell the device for $200 on ebay. : ) Thanks in advance, Rob 95 M3 "Grampy"

Any dyno results yet? Also on the Rogue website it says that they have "optimized 57.2mm twin inlets"? I thought that the stock was 60mm? I know that AA runs 58mm and UUC runs 60mm. Anyone with thoughts to why Rogue would go with a smaller diameter tubing? steve

As worked flawlessly for nearly 3 years. Cheers, Jim Bassett
