who is getting all uppity? I will let others handle the idle vs. slow idle/slow running of the driveline. Simple answer is a question for the rest of it though. What is not warmed up by simply just idling? Without a doubt idle/fast running is stupid compared to idle/slow running/fast running.
I think it's a fact that the car warms up better when moving/being driven.....i read somewhere that it is not necessary to idle for more than 30 seconds
I think it's a fact does not cut it. There needs to be an explanation based on physical processes. Thanks for trying to help but I'm trying to get away from hearsay.
After I created this thread (based on my experience), I did some searching and this is a very debated topic. I understand both sides of the argument, however, with my Ferrari (F1), the difference was great and I have no plans to change. And, much of what I read was based on all temperature ranges (Mother Nature) and my F car is only driven in warm weather. But, as posted prior, I do plan to do some other tests but did not drive this weekend since I've been blessed with a kidney stone ;-)
It is common sense. Idling does not COMPLETLEY warm up the car and adds additional risk for overheating if the cooling systems aren't working properly. How many times in history has someone started the Ferrari, gone back inside and got distracted by other stuff, went back out to the garage to find a burnt overheated engine because the thermostat didn't open or fans didn't come on. Even if the cooling system is working properly at idle there is isolated heat soak and uneven cooling as cars are designed to operate properly while moving and then just "survive" idling. still putting all that to side what blows the long idle out of the water is that there are many systems that aren't warmed up at all. The only common sense answer is a idle warmup/slow drive/fast drive. long idle/fast drive is stupid stupid stupid.
Rob, you're failing to see my point on how this HELPED me and others with the F1. I'm not suggesting idle / race at all....
it is obvious that your F1 will work better with proper warmup, why weren't you warming it up properly in the first place? EVERY car owner should know this basic practice when they get drivers license at 16 years old. the common sense we're trying to show is warmup involves more than driveline and your F1 will be as warmed up with idle and slow drive vs. long idle. all while properly warming everything else as well with lower risks.
Well to be fair most modern cars do not require a "proper warmup". My wife's 2011 BMW owners manual specifically states: "Do not warm up the engine with the car at a standstill; it is preferable to set off straight away, driving at moderate engine speeds. This is the quickest way for the cold engine to reach its operating temperature". I'm not suggesting this is the way to go for a '90s Ferrari (I'm in the "few minutes of idling / slow driving / then when up to full temp go for it" camp), but to suggest prolonged stationary idling to warm up is an essential basic driving habit is not necessarily correct.
It takes longer for the engine to warm up if it is sitting and idling, hence more acid and particulate build up in the oil than if you warm the engine up more quickly. That is not conjecture.
still, we're trying to convince you why common sense you should change your warmup procedure a little. I'm not mad at anyone, people can do what they want, but no one can make a valid argument why 15 and fast is better than 5, slow, and fast.
If I get the same results at 5 minutes (as I said prior I would try), then I will go down to 5. The number, 2, 3, 5, 7, 10, etc will be based on whatever amount of time it takes for MY car to respond as it did when I created this thread. What others do is up to them, but I know what I'll do because the results where fantastic.
I don't think anyone has proposed 15 and fast except for you. And all I'm hearing is religion, with no detailed explanation of what is physically happening to cause someone to conclude that for instance acid builds up faster when idling versus not idling. The question is why should that happen, what process is taking place when idling that causes different chemical reactions to occur that supposedly do not occur if you are driving. What specific components are not getting warmed up when idling? It's not very informative to declare that components are not getting warmed up and leave it at that. What components? What acid, why?
5 and slow and go, not 5 and go. actually it can vary 1,2,3, 5... based on air temps. the point is 15 or even 10 is pretty excessive.
it has been mentioned 10 times, just proof you aren't reading the thread and making up what you want to believe = trolling.
As far as Ferrari goes, that's no. So, you don't have first hand experience with what I'm saying and others that have F1's that have agreeded with me. I love the F1 but some control is given up to the computer which is still i nthe hands of the driver with a non-F1 car..
The GranSport F1 is similar or same to the Ferrari systems and it has similar and same driveline components like the 430 block. However, I do realize the 355 F1 was a much earlier and inferior system. common sense F1 system will be similarly warmed up 15 minutes idle or 5 minutes idle/period of slow drive. the key to this entire discussion is all other benefits of a proper warmup. I have better things to do with my time than trying to fix...
I do own an F1 and despite what I posted previously about modern cars I think it makes sense to at least give it a couple of minutes to warm up before driving off. Once I've done that I still won't let it go past 4000rpm until it is properly warm (around 10 minutes after starting). Having said that I'd be reluctant to let it sit idling for 10 or 15 minutes. Just doesn't seem right. Bear in mind I am in Australia where even the awful depths of winter rarely go below 10C. However my lovely wife usually kicks me and the car out of the garage once it's been started for a few minutes because it starts to stink up the house with car/petrol fumes! Haha!
Certainly the F1 system has evolved but I still think it's fantastic in the 355. Is the GradSport a 100% manual transmission? (meaning no torque converter?) I know nothing about those cars but think they are awesome And the key to this discussion is the reason why I started the thread. FOR ME, and my F1, the warm up made a huge difference.
