Does an else get the 'burnt asparagus' smell after holding your STi on an incline with the clutch? (Like for a hill start).

When I first got the STi I used to smell this burn-off quite a bit but now I only smell it if I'm not too nice with the clutch.

BTW I don't abuse the clutch - never have. No 'drop the clutch' starts - never.

Hmmm, I have not noticed any burnt clutch smells... well, once or twice practicing launching. I did notice the new engine smell at first but nothing clutch till after I broke it in and I had a couple bad launches. I very rarely hold my STi on a hill with the clutch other than a split second before moving. I am not sure how long you hold yours on a hill with the clutch but I know you are not suppose to hold the car from rolling back with the clutch.

... I did notice the new engine smell at first but nothing clutch till after I broke it in ...

At first I had lots of that new engine smell too, especially the first few weeks when I was babying the car - I find this new smell to be very similar but only when the clutch is involved. Could this just be the same as new engine burn-off on the clutch or am I harming my clutch? I've also noticed the smell sometimes if I make a bad mistake while moving through the gears.

As for hill-holding - it was a one-time experience, pretty flat where I live. I had the car in Syracuse, NY at the time and just happened to get stuck at a light on a very steep hill with traffic creeping up my tailpipe - I didn't feel comfortable using the brake and risk rolling back into someone behind me.

Wow...you should NEVER hold your car on an incline with a sustained clutch slipping. It isn't so much just the wear of the clutch, but the temperatures that can be reached during a prolonged slippage.

I have seen firsthand what a glazed clutch looks like. Before I knew how to properly (or comfortably) rev match during downshifts, I did a fast autox course in my old Z24 that had a 3 to 1 downshift that I performed by just shifting from 3 down to one and slipping the clutch out until the car slowed to a proper speed that I could engage the clutch fully (with brakes too of course). The result....a clutch that slipped for a long time till the glazed layer was worn through as well as a toasted set of synchros.

Needless to say, when the dealer pulled the clutch, that sucker was BLUE from the heat. Not a good thing. If you do hill holding manuvers as you described, you will have the same thing.

Bottom line...there are two states a clutch is safe in...engaged and disengaged. Anything in between....keep to a minimum.

i agree with clone, you are smelling the clutch because you are slipping it the whole time. if you are nervous about rolling back on a hill do the e-brake trick... that will at least minimize the slip until your feet are fast enough to do it the right way

Does an else get the 'burnt asparagus' smell...

heck yeah! i hate it. we get the same smell on our '00 outback also. however, we live on a hill and our driveway is one of the steepist in the neighborhood, so we need to slip more than most.

as a further "however", we have two nissans and we've *never* gotten this smell (except for the one time i totally botched an autox start). i seriously doubt we're driving the subarus differently from the nissans.

therefore, i have to think subaru must have the clutch vented, or their clutch material is significantly different/smellier. (my '82 subaru hatchback had a flap-like think on the transaxle you could open up to see the flywheel. this *might* have been used for setting the timing, but i don't remember. no reason for this kinda think on the current cars though.)

I got the smell once, foolishly trying to spin the tires from a stop sign after someone ran it the other way, almost nailed me!! I mean how do you not see the electric blue and the huge spoiler?? I think it goes without saying, use the brakes on the hill...

...you are smelling the clutch because you are slipping it the whole time....

well, i can't speak for lars, but, egads!, i'm certainly not holding the car on the hill by slipping the clutch. in my case, i'm talking about moving from a stop midway up a steep driveway into your garage; something you want to do slowly and carefully. in this case, you're gonna slip more than you would just moving from a stop on a steep road.
