Could the people who leave their cars to warm up for 5+ minutes explain to the rest of us why you feel it's neccessary?

I tried to weigh up the pros and cons, and there doesn't seem to be much of an upside to allowing the car to warm up at idle.

Cons

1/ It's a waste of fuel

2/ It's a waste of money

3/ Car takes longer to get to running temp when at idle

4/ It pisses the neighbours off

5/ Motors are designed to have air flowing through them while the car is moving forward. This doesn't happen when the car is sitting still.

The air that is being sucked in to the motor is warm engine air... if anything, wouldn't this cause the temperature to rise faster than if you were driving, thus being more likely to cause damage to components which are prone to warping/heat damage?

6/ People figure that if the car has been "warmed up" that it's safe to thrash the crap out of it as soon as you get out of the driveway.

Pros

you must hav got up on a cold morning gone to start the car drive off and it just doesnt drive properly. It lags, stutters and genrally isnt happy

leting it run for a minute eliminates most of those issues and most importantly of all it gives u peace of mind. thats the main reason people do it

P.S. who gives a shit about their neighbours?? haha i hate mine with a passion

One minute is within reason...

I make sure that I can hear the lifters have quietened down so that I know oil is getting to where it's needed, but once that's accomplished, it's time to go.

However, I wasn't questioning one minute, I was questioning 5+ minutes.

As for the neighbour comment, I'm a victim of this.... a neighbour has an extremely loud (hunk of crap) car that they like to leave idling for up to half an hour at a time. :cheers:

all of the above.Also,when it get's home the bonnet is lifted up.It stays very warm in the enclosed area of the garage especially in the summer months..

Looks like you and I are the only ones that do this :cheers:

I'm surprised more people don't. It's a great way to increase the life of everything under the bonnet IMO

Start car as soon as I get in then choose a cd, put belt on, pack car. Anywhere from 30 seconds to 2 minutes. Then I just take it easy keeping the revs down and boost at 0 or vacume until the guage reaches as high as it goes which is just below half. This usually takes about 3-5 minutes of driving. After that she's good to thrash.

As for cooling down, I take it easy for the last 2 minutes then shut it straight off. If taking it easy wasn't an option :O then I'll set the timer to 2 mins or so. I rarely use the turbo timer at all though.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
