My first turbo car, need tips !

Hello Alfisti,

I'm getting my CL (I never had a turbo car before ) this weekend and I would like to get some general tips about driving a turbo car and some special tips for driving a CL. I made some research on the internet but your opinions are more important to me. I'm sure it will help other alfisti too. Thank you very much.

Standard advice for turbo charged cars used to be: Don't drive them too hard from cold or just before the end of your journey. It's good advice for any engine though

Hi,

After a hard push to the revs, just let the car run on idle for a while to let it cool down enough with the help of engine oil and coolant system. (not sure if it is same on this engine as well). Stopping the engine without cooling it will reduce the life. Same is valid once you start the engine, let the oiling to establish a proper film something like 10-20 secs.

best wishes...

When the car is cold, change gear early (1500rpm or less) and be very light on the throttle. The CL has plenty of torque to pull from low revs (I drive like this to also decrease fuel consumption when the car is warm - the shift indicators help nowadays for people who don't know when to change gear).
The same applies for any other engine when its cold.
I mean just imagine being told to sprint straight out of bed...not a happy bunny! You have give time for the "heart" to warm up.

Is there an indicator which shows if the turbo charger is cool enough to stop the engine or do you choose the right time by instinct?

Hmm, what about start&stop? Does it keep water flowing to the turbo when the engine dies?

I'm thinking of disabling start/stop completely, I just don't like the idea,because in Istanbul, there's traffic everywhere and I think it will hurt the motor just to save 1 or 2 liters of benzin.

Assuming the CL has a different turbo set up to the 1.4MA, is this the reason that Start-Stop is not available on this model? Always wondered why the CL had been excluded.

Probably cause the other models are intended to attract certain school of interest based on the fuel economy while CL is the performance model and does not have to sell based on mpg.

As mentioned above,
1. Dont push the car when its not up to normal operating temperature. This is because the engine oil will not be at its most efficient. It will be slightly thicker while its cold so it takes more effort to pump it around the bearings, therefore bearings might not get full protection.

2. Don't turn the engine off straight after a work out, even if it was just one hard acceleration (up to 6000rpm say) from the end of the road and a quick stop at the side of the road. The turbo might not be glowing hot, but its internal spindle could be spinning at speeds close to 150,000rpm. Some modern turbo's can be spinning op to 220,000rpm. Stopping the engine instantly stops the oil pump and with your turbo still whizzing away will mean that its bearings may be starved of oil while it slows down.
Its always best to let your car idle for 30 seconds before switching it off.

3. Never blip the throttle before you turn off the engine for the same reason as 2.

4. As mentioned above, turbo's can get very hot too, up to 1000 degrees. If you have been on an enthusiastic run, give your car a little more time for the car to idle and cool before stopping the engine.

I hope this helps

I wonder if MA's have electric oil pumps to compensate for my comments above when stop/start kicks in. Does anyone know if this is the case?

I've been wondering that too about these start/stop engines. I've read that every time you start your car the engine wears out as much as during hundreds of miles of highway driving, which makes sense. So how that reflects on the engine life say if you do a lot of city driving..I don't know.

"Hundreds of miles" sounds bogus (I'm reminded of the claim about fluorescent lamps using an hour's worth of electricity in the first minute - not true), but the engine does wear slightly more when started first. Much of that wear is due to cold engine parts, however, and on a S&S system, the engine is warmed up and still lubricated when it restarts.

It's not like they bolted the S&S control logic onto a standard engine either: the turbo, alternator and starter motor are all specifically designed for, or differently controlled for, the Start/Stop system, and the engine control would be adapted for it too.

AlfredTI's advice is pretty much what a mechanic friend told me. Don't turn the engine off at the end of a heavy run - give it a minute to dissipate the heat out of the turbo. In some countries, where it's allowed, BMW's turbodiesel cars keep the engine turning until it reaches a safe temperature, even after the key is removed. This is a problem particulalry if you live or work in a rural area, where you're doing 50-60mph all the way to/from where you park.

Kris - I remember the old days of "turbo timers" A couple of mates who had an Escort Turbo and an Import MR2 Turbo used them to run the engine for 2/3 minutes after removing the key from the ignition.
