Had those on my cavalier!

If they needed turbo timers, I'm sure the manufacturers would fit them as standard, but having said that, i always sit and let my old girl idle for 20-30 seconds at least before switching it off. Its not going to do any harm, and like Adamwest says, treat the old girl like a lady until you have her up to temp before you ask for too much and she will look after you for years. Ask any woman!!

nah.. 4 barrels hollys are where its at!!

What do you mean those were the days I am still running them on my mk1 cortina ow the sound is glorious

I had an early mk2 with the 1500 cc engine. Fitted webbers to it and boy did I think I was the bees knees. Tried to fit the Lotus cortina engine to it but made a right cock up. Got all my money back selling it in parts and guess what bought a Vauxhall HB viva WOW. What taste I didn't have.

I upgraded the solex (with pre-heater) on my 2a to an SU off a rover 3000... it was an amazing upgrade, just the right size and jetting, only had to adjust the idle mixture. Gave instant power, unlike the solex

When I had my “pocket rocket jap” with big turbo, the turbo timer would allow me to park, get out, lock the car and it would continue running for 1min or more if set. It was strange at first to hear the car still running while I put the kettle on in the house and then it shuts off.
If it was late at night I used to make sure I poodled the last mile to ensure the temps were all low (as could be)so I could turn off when I got home.
It never got booted till it was warm.

There is absolutely no harm in trying anything to be mechanical sympathetic, including warm up. Something some drivers don’t understand sadly

I say to the OP keep doing it won’t do any harm.

No they would not, failure provides the service departments bread and butter.

My first experience of turbo diesels was on Ford 360 turbos' in heavy trucks back in the early 'seventies.
The instructions (then) were to allow the engine to idle for at least one minute prior to shutting down.
Not really relevant here, but back in the 'thirties/'forties it was recommended leaving petrol engines to idle for a short while in order for the valves to cool

Hummmm Project binky, been following that, top notch work they are doing

The reasons for leaving an engine running was the oil flow would cool down the turbo. It isn't really that important, since a combination of batter designed turbos, oils, and just the low speed driving you do to park a vehicle is enough to remove the excess heat. A turbo will also quickly come to a stop when the exhaust gasses stop. Pop off the cold side of your turbo, start the engine then stop. You'll see the turbine would be stationary by the time you walk around to check it.

For sure, don't cane it from cold, as there is where the damage is done, but less of an issue shutting down. Unless you come haring around the estate, valves bouncing out of the bonnet, and shut down immediately. But if that is how you drive, then you might as well buy shares in eBay special Chinesium turbo kits.

That all said, if it is a habit you have, it isn't a terrible habit. I usually like to get everything ready for hopping out before I shutdown, just because I got into the habit when I lived in the middle of nowhere and I liked to sit in the heat as long as possible.

Think it was you that first alerted me to it. Excellent stuff.

I’ve always let it cool a little on last peg of a long journey, especially a turbo diesel. I give it 20-30 secs to idle as I knock everything off, prefer the heat to spread out more evenly while everything is still pumping. No way of telling if it actually makes a difference but works for me
