how long does it take a t350c to warm up? If you leave it running for 10 mins from cold can you get in it and boot it?

[nubbin]

Course you can! (If you want an engine rebuild at 1500 miles....)

Why are you asking?

[blueyes]

2.5 seconds if you drop a ciggy in the petrol tank

Seriously though it does take some time to warm up sufficiently for you to give it some beans.

John Ravenscroft’s Tips on Mechanical Sympathy and his Engines!

FROM COLD

When starting, please be careful not to let it rev straight up so please make sure that you do not give it anything more than a tiny bit of throttle while cranking it over and then lift off as soon as it catches.

Then try to avoid more than 3,000 rpm until the oil (not water) temperature has exceeded 40°C, 4,000 rpm until 60°C and 7,000 rpm until 80°C. If it climbs above 110°C, please keep the revs below 5,000 rpm until the oil temperature returns to normal.
------------------------------

Based on the above it really depends upon what you do after starting the engine.

For me, on most journeys I hit a dual carriageway after about 2 miles and then travelling at 80mph (3000rpm in 5th - max rpm until oil reaches 40°C) the airflow through the engine bay keeps the temperature below 60°C for a very long time, in fact from cold at constant speeds I haven’t ever seen the temperature rise above about 46°C until I have slowed or stopped for a roundabout or a junction. Obviously start and stop driving it takes a lot less time and distance.

I haven't tried just starting it and letting it run until it reaches 60°C so I couldn't tell you how long it takes - one thing I would say is that although the engine oil temperature does rise you should also consider transmission oil, bearings and brakes that need heat to perform properly.

I really wouldn't risk not letting the car (engine / transmission / brakes etc) warm up properly. It just isn’t worth the financial pain / inconvenience or life threat (if engine expires during hard cornering causing over-steer or cold brakes not slowing you down quick enough)…

One question I have never managed to get answered is exactly what maximum RPM these cars should be run to at the max? I assume I am correct in suspecting there is no rev limiter?

[Dan]

Also remember doing this will mean that although the engine is nice and toastie, the gearbox and diff will be icey cold.

Caning a car in these circumstances will lead to transmission wear if not failure. I believe someone in a Cerbie did exacltey this and blew a diff.

The rev limiter is there and it kicks in at about 7500rpm on my Tamora.

Definitely wouldn't recommend getting there before the oil temp reaches 80C and the rest of the car including the tyres is nicely warmed up...

I didnt know the Tamora had a rev limiter?

[spenny]

My dealer told me they dont. Some on here say they do, some say they don't. I'm confused. I'll go for the "dont" assumption and wont try to find it!

[nubbin]

They do have a rev limiter - I've hit it once or twice

Was that whilst on the road, or flying through the air?

[dylanp]

There's definitely a rev limiter and I've tried it several times at the Bedford Autodrome on the 19th...

Roughly about 7500 rev it cuts the fuel supply until it drops to below 7500.

Good fun Bedford Autodrome by the way - recommend it to anyone here... Quite fast and very safe!

If it's your car and you paid for it, you can do what you want to it.
