As she has just had the sports exhaust fitted I am assuming that the heat smell from the rear which is pretty obvious and you can smell from several feet a way is the new exhaust gubbins that protects it just burning off.

Suggestion
Racing drivers change gear to be in the correct gear at the optimum revs level - not to slow the car - they have very expensive and effective brakes for that.

Suggestion
In fact using the gearbox causes premature wear on the drive train and additionally unstabilises the car just when you most need stability.

"Warming up " is as old fashioned as using the gears to slow down.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi,
Having only had my C4S for 4 days still so many questions now I have her. As she has just had the sports exhaust fitted I am assuming that the heat smell from the rear which is pretty obvious and you can smell from several feet a way is the new exhaust gubbins that protects it just burning off. Or is it normal for there to be a warm smell for want of a better explanation as the exhaust gets very hot anyway??
Also is there any specific start up procedure, I visited a guy who had been drving Porsches for many years and he stated to me that each and every time he got in his C4 he let the engine warm up for 3 mins then drove off. Is there a specific engine temperature to allow minimal wear and tear on initial start up?? Not found anything specific in the manual.
Cheers Alan.

i think its fair to say that you should take it easy until the engine reaches its normal temp.
not sure about the warm smell though, not got a c4s.

Over 80? My car just about gets to 80 under normal driving conditions..
Must be all that delicious titanium and other exotica at the back keeping her cool :wink:

I get a 'hot' smell at the rear as well as well as a lot of 'tinkling'...and hot air around the whole rear end.
As Daz says wait til temp gauge reads 80, but bear in mind thats water temp and you should allow a bit more time for the oil temp to get up too.
Another tip that I've just learnt, look in to investing in a trickle charger if you are not doing frequent long distances and want to keep the battery life up.

All current printed advice says just drive off - never leave a car to "warm up" - just be gentle and progressively increase the revs , speed and throttle openings.
"Warming up " is as old fashioned as using the gears to slow down.
It comes from the 1940's.
Trust me I'm a doctor...
Oh - by the way.....
"and hot air around the whole rear end."
Thats the Jaylow effect - or baked beans!

My C4S with Sports Exhaust is the same, although now the car is 3 weeks old, the smell is diminishing - I just put it down to it being a new car and burning off the coating on the exhaust.....

I've always experienced exactly the same issues with both my SC and 996. I assumed this was just something normal with 911s.

Why not use the gears to slow down ?
dont racing drivers use them to slow down?
Could you please explain?
===========================================
When cars had drum brakes and linings made of old fag packets it was necessary to use the gears to help slow the car - but since the invention of disk brakes this has been unnecessary. In fact using the gearbox causes premature wear on the drive train and additionally unstabilises the car just when you most need stability.
Racing drivers change gear to be in the correct gear at the optimum revs level - not to slow the car - they have very expensive and effective brakes for that.
Warming up a car by letting it idle has been outmoded for years, modern oils make this ancient practice a waste of time and fuel at best - some car owners manuals even included phrases like "drive off immediately". The tick-over speed simply prolongs warming up to no useful purpose.
Porsche Carrera (993) drivers manual page 35, says
"Do not allow the engine to warm up in neutral but drive off immediately while avoiding high rpm and full throttle until the engine has reached its normal operating temperature."
Audi A3 drivers manual page 164 says
"Do not warm up the engine when the vehicle is stationery. You should drive off immediately whenever possible.
Obviously no advanced drivers here.... :wink:
