How many minutes do you let the engine run...

[sflrainmaker01]

How many minutes do you all let the engine run before you put in gear and take off? Is there a "warm-up" time frame? The reason I ask is, I usually let the car run for at least a couple minutes before I put it in gear. Then, the morning commute is about 3 miles before it gets to 45-55 mph driving. HOWEVER, when leaving work, its only ONE mile to the Interstate and it just seems like it might be a little stressful to the engine to almost immediately start a 5 mile long 2500 rpm stretch. :dunno:

I spoke to Jeff at Mo's about that very thing. He said he likes to let it raise up to about 160* before driving. I have an interceptor gauge so I can watch it but my needle goes about to about 40% and it's around the 160. This allows the fluids to heat up and get the pressures to normal range.

About 30 seconds, basically enough time to let the air suspension pump up. In the winter i let it warm up to about 100°f then i go. I take it easy the first few minutes either way.

Exact same.

20-40 seconds, no heavy throttle until I see the temperature gauge start to move off of the C.

^^^WHAT THEY SAID^^^

I've noticed it's about 30 seconds for the idle to kick down and settle from a cold start. I wait for that to put it in gear.

[Krytin]

30 sec to a minute, then less than 30 mph for the first mile.

[RacerX]

I bet it's about 10 seconds with Dom. Just enough time to get the glow plugs hot! :D

[tbone]

I start it and floor it.
:burnout:

[L.Mark]

When it's cold I let it idle for a couple of minutes then take off. The needle usually starts to move before I'm a mile down the road...I'm about5-10 minutes before highway speeds though...

This^^^^^^^ :laugh:

[james79stang]

In morning I start it, drop it right into gear. get about 1.5 miles from home and hit it to get upto 65mph. I do have 239k on original engine.:burnout:

[gdmjoe]

.
Minimum of 2 minutes.
.
1 minute if the coolant temp' is already 100°F +

No WOT until coolant is 120°F +
.

[1Marauder]

About a minute in the drive way (because I don't drive them every day), then slow driving for the 1.5 miles plus... till the gauge moves above the first temp line, and the transmission has warmed up... then WOT on the uphill onramp to the freeway... Second gear and third gears hit so hard they want to break loose!

[Limited360]

My development car.... It's in gear as soon as it starts..., so .5 seconds or so... :) within 5 seconds I am at Wot pulling out into a 45mph zone.

My Marauder, I let it idle for ~5 min or so then it goes into gear and I leave driveway slow . Warm up Trans and then romp on it...

[Invader]

I let it run until the throttle kicks down. I would be more concerned with letting it warm up to operating temp before turning it off. Just my .02.

[Zack]

I'm in reverse before the idle settles down.

I've heard differently for years...not doubting but, I would think it would help...

[MyBlackBeasts]

Idling for extended period before taking off is old wives tale.

Oil pressure is up & flowing almost instantly.

The fastest way to warm an engine up is putting a load on it.

30 seconds & put in gear and drive normal, then when up to temp = OK for WOT time! :burnout:

So, when at the track, I thought it was better to "cool the engine"? Should you be at operating temp when making a pass or is it better to be on the cooler side?

[whitey]

In racing it is good to have a cool motor to an extent... if you go from cold to hot in the matter of a few seconds, stuff is bound to break. Different metals heat up at different rates, and the heat transfer between parts could warp some stuff. I would think anything colder then 120° or so to a rapid 190° would be bad. These are just my guess, im sure someone with better experience will chime in. Theres a difference between cold, cool, warm, and hot.

[TJCOX]

I put it reverse or drive and go, depending on the temperatures.

That's what I was thinking too. Being here in Florida, cold is not really cold! ;)
For example, yesterday (when I was leaving work and thinking about this) it was a pretty warm day. So, it was 85 degrees. It would take no time to warm it up to 100 or 120 degrees. :P

[Bluerauder]

I'll generally let it run until the idle drops down to the 650-700 RPM range. Its usually up to full operating temps about halfway to the Interstate.

[Pat]

Start it, do some cockpit business, charge up the machine guns then motor out of the housing area, 1.5 miles @ < 25 MPH, then normal driving 35-60 MPH.

Seat belt lights turns off, I'm gone!

[IwantmyMMnow!]

On the first start up of the day, I'll let it idle for about a minute, longer if it is cold outside (40s or lower, mainly to get it warmed up enough to produce heat inside). I always get to operating temp before I am able to go 55mph or faster.

In really cold weather...below 30°F, I do this:
30 seconds & put in gear and drive normal

[Pat]

Sent belt lights hours off, I'm gone!


Please translate this statement.

[TAKEDOWN]

Lol, sorry... seat belt light off and im gone!

[MitchB]

Something to think about - not that this will change how anyone does anything.

I'm most familiar with my 96 4.6 TBird. Looking at a datalog of the idle air integrator, it consistently shows a peak at around 120 degrees - regardless of the initial start-up temp. This is where there is maximum friction as a result of the pistons expanding before the block.

[lji372]

Start it and drive at normal speed 5-69 :D I just don't stomp on it till the temp gage rises

[Bigdogjim]

Turn the key to the on position and wait 4-5 seconds then crank, wait till idle drops and stay under 35MPH till engine is warmed up. Temp gauge will move a little or I'll use the scan gauge that is hooked up.

[88CuttyClassic]

Im balls out as soon as i put it in drive. Theres no way i could more harsh on this car than police or taxi drivers.

What he said, but I don't go WOT until it is warmed up....(usually)
