You're a donkey. I like that.
So here's a question for people with BMW's with manual transmissions:
How much clutch and what RPM range do you generally start off with? I'm talking for day to day stuff, not hill starts or fast launches.

I'm asking because I've noticed something with the BMWs I've owned that have self adjusting clutches. They seem to work better if I "burn" a little more clutch. Higher RPM, slightly longer slip times seem to improve things. Shifts are smoother, the clutch stays lighter and has more consistent feel. My clutch also has a slight pop or click feel to it, but I can get it to go away if I slip the clutch a bit more or rev higher. I'm talking in the 1500-1800 RPM range.

I was taught to keep revs low (I've been in the 1000-1200 range) and not slip too much, but my shifts go to poo poo after a while. If I wind the car out to red line through a few gears, shifts improve dramatically. This didn't happen with my BMWs with NON self adjusting clutches or in other cars.

Thoughts?

I find my e39 to be a bit touchy in starting off in first. A lot of people will drive it and slam the tach to 2k+ while letting it out, because the SAC makes the friction point so far out and the pressure plate itself is so unpredictable. It's been a few months now, so I pull from a stop in first at 1200. One of the hardest cars I've ever had for starting off in first, though, other than an '03 lotus esprit, which had a dual plate clutch.

I deleted the CDV and the clutch is fairly new (<10k miles), just for reference.

I'd say I typically am in the 1200-1500 range. It's certainly jerky if I don't let the clutch slip for a second or two. My old E34 was smoother in that regard than my current E46, and I've removed the delay valve from my E46. Other than starting in first though, quick clutch releases are clean and smooth.

Higher RPM with slip is easier although I've found low RPM to be fine but you have to get it just right or it will start to lurch. I have done the CDV delete and have an extended clutch-stop-nubbin-thing that makes it much more comfortable for me.

I have an '00 Esprit and it's a million times easier to take off smoothly than my Z4 M (also CDV removed, though that didn't really make much of a difference I've noticed).

Been driving that drat M for like six years and I still dread taking anyone driving in it because I know I stand a more or less equal chance of shifting smooth as butter or causing a learner's-permit shuddering jolt and looking like a colossal pud.

Oh yeah, I forgot I did this, too. It was also quite helpful since it removed some of the really excessive pedal travel toward the bottom, long after the clutch has fully disengaged. Worth the $10 or whatever it was.

I generally dont mind slipping a little clutch to get going, as long as the low end throttle response is nice and linear. My stupid 08' civic has really gutless low end that sort of jumps from idle to 1500 rpm without much actuation between, which makes my normal way of launching either a lurch or a long slip. Its frustrating as hell and ruins what is otherwise a perfectly good commuter appliance. Not sure if its related to drive by wire, or just the engines normal characteristics.

I cant wait to off that loving thing for another daily that I like better. Maybe that e46 330xi I mentioned earlier...

How does the nub make it better, and does anyone other than UUC make it? On my e39, nothing has made the clutch feel better than replacing the (blown) motor mounts with 750il/m5 ones. It is so much less jerky, from a stop I'm under 1k RPM with no issues. Car is still super cush with the 500rpm idle.

I did the nub the home depot way, there was a DIY on e46fanatics or the zhp forum on how to do it. If I remember right it's just a plastic round thing with a threaded end - think a big plastic button (~2" diameter) with a bolt about 1-2" long on one side. It threads right into where the stock one is (or there is just a perfect hole there). I forget what/where the plastic thing is for but it's some random household gizmo stocked in hardware stores. Then you stick a big furniture slidey pad on it. Costs like $1, mine has been on a few years.

It just reduces the distance you have to push the pedal. The pedal is effectively 100% pushed before it hits the stop, so there is an extra couple inches of travel that are pointless, and for me kinda messed up in my head my idea of when the clutch should be letting out based on my foot pressure. The longer nub removes that slack. Made a noticable difference for me. I also hate long leg travel distance, I'm not short but whenever I get in someone else's car it feels like they have to fully extend their legs to hit the pedals, I am weird and like to sit close and not extend my legs much.

Opposite reason actually. I hate manual trans cars with gummy motor mounts. They make it feel like a slight delay in power delivery, especially after shifts. These are harder than the stock ones.

My Z4M is the only manual I've ever driven regularly so I don't really have a good frame of reference, but I find it starts from 1st easiest when I bring the revs up to almost 2k and then let it fall down a bit while I blend in the clutch. I guess I don't really know what "slipping" the clutch sounds/feels like, but it doesn't chirp the tires or make any weird noises. And I'm not riding the clutch.

I learned to minimize clutch use driving cars with 9lb flywheels and 6 puck unsprung clutch disks.

Even in the torqueless wonder that is a Miata, the revs were never higher than 1.5k starting out in first.

1.5k in a Miata is going to lug in a major way. Riding the clutch is the people who have their foot on the clutch pedal just driving down the toad.

LOL no it won't, torque multiplication in 1st is a wonderful thing. I wish I still had the car so I could record it.

There is no reason to slip the clutch for a full second at 2k. Especially in a z4m with plenty of torque to get going.

I have a 09/09 production date 135 and I just found out that if you have the USB/IPOD option (6FL) on a '10 or newer you can basically code your car to have bluetooth and sirius. I bought a generic bluetooth antenna, 6" of SMB female to female cable, and 3 MQS pins. I rerouted the microphone cable for voice control to the MULF2 in the trunk, soldered the 3 MQS pins on and pinned it in the connector, plugged the bluetooth antenna into the MULF2 and coded the car's VO with $644. I reset the ECU and I now have bluetooth for ~$50 of parts. And (worthless) voice control still works, coding the car changes where it expects the microphone to be plugged in.

For sirius it was a bit more expensive as I had to buy a FSC code (I paid $200 for it), but once you have that file it is literally just coding the car. The radio is already a sirius receiver, BMW just disables it in coding so you have to pay $800 for a dealer to turn it on later. And since I was the original owner of the car I got 1 year for free once I called sirius to activate the receiver.

I also got a navigation FSC code when I bought the sirius one, 2015 maps are much better than the 2009 ones.

Overall, ~$250 plus about 2 hours of my time. Totally worth it.

They're a little hard for my taste but last for loving ever. Good for a performance-oriented commuter that isn't going to see any A/X or HPDE.

Also, update on ducky's 30.
I've had parts sitting here, ready to go, for like 2 months but my rear end in a top hat friend decided to go blow up his s52 head so that took priority. Now that he's out of my long-term project bay, I can start yanking the heart out of this bitch.

:byewhore:



Beauty shot:


While some buddies started getting the one loving solid piece exhaust, god drat you P.O! Off by yanking the headers.

I started yanking stuff off the rear. I am a retard and started undoing the RTAB bolts before realizing the whole kit and kaboodle can come out as one piece.

As well as losing a lot of gasoline, pointlessly.


Little six intake makes for great bourbon drink storage.


Undoing the big bolts


gently caress you, ya heavy bastard!


The liquor had begun to kick by this point so we went back to yanking stubborn exhaust studs.


God. drat. Ebay. Headers.


gently caress it, more bourbon


Where we sit, now.


I'm heading out to try and source an oil pan this morning. If I can do that, on the way back, I'll swing by a friends dad's and borrow his engine hoist so we can get some blood back in her.
When we took the filter out, literally no oil dripped out. :negative:
