Warmup procedure
Discussion
I have often read on this and other forums that TVR engines should be properly warmed up [I assume this applies to all engines, but more important with TVRs].
What is this procedure? Is it just a matter of doing the usual pre-startup checks like fluid levels then start her up and idle until 80°C is indicated before moving off? Drive straight away keeping the revs below 3,000RPM until 80°C? Or is it something else?
I ask because, though it maybe an old wives tale, I thought it is not good to just start the engine and let it idle on the drive because the oil does not 'slosh' around to coat parts of the 'innards'. Apologies if I got a bit technical there.
I'm particularly interested in V8 configurations as I am looking for a Chimaera, although if it differs for speed 6 motors I'd be interested anyway.

I'm not mechanically minded, but have my own way of doing things having read what others have suggested.
A short warming up seems a good idea, to get the oil sloshing around and covering all surfaces as well as thinned out a bit (this would seem especially important on the dry sump speed sixes), say while you close the garage or pfaff around with sunglasses/CD/seatbelt/lippy, if you've got an urban area to drive through then you can probably go straight away as the car will gently warm up as you move towards more fun roads.
So I then drive off, limiting myself to around 3000rpm until warmed up, which let's face it in a TVR is still enough to entertain
The warmed up point I use on the Cerb is to wait for the water temp to get to standard and then watch the oil pressure, as after a while is just dips slightly, which to me indicates the oil is all nice and warm.
I've seen people religiously warm their car at idle for ten minutes then scream off out of a car-park, besides having cold tyres with lower grip than usual, the diff and gearbox oil will be stone cold, as well as the brake pads and fluid.

Hi there, our advice and 'rule of thumb' for Speed Six engined cars is when started flick to the OIL temp readout screen and try not to exceed 2,500 rpm until the OIL temp has reached 40 degrees, after it has achieved this temp then it is acceptable to use more revs. If you want to examine the higher reaches of the rev range then the car should be fully warmed through and be showing 60 degrees plus. If the OIL temp starts to exceed 110 degrees slow down, reduce revs and let the OIL temp drop back to an acceptable reading. (Really should only occurr during a trackday). Also it is worth being fastidious when it comes to checking the oil level, engine at operating temp, level ground, within a minute of switching off. Hope that this helps and best regards, Tony
