warming up the rv8

[snookes]

what is the correct way to warm up the rv8 prior to using the full rev range

thanks

Do not exceed 3000 rpm until the water temp reaches 80 degrees centigrade .

Also don't let it idle too long. The oil won't get up to the cam.

I'm lucky 'cos where I live I have a 1.5 mile drive at 30mph to get out of the village, which forces me to keep it about 1500-2000rpm.

I can then open it up to 4k quite soon, and by the time I get to the motorway the sky's the limit!

Just remember though, the water temp will come up very quickly but the engine temp is the oil temperature. The wedge doesnt have one of these, so basically wait till you think it going to be up to temp...

You cant be too careful...

Anyway, combine are you sugesting that one would rev over 3000 rpm????!!!

[adam quantrill]

shurely you mean _under_ 4000 rpm???

[matt-man]

er................ !!!!

The factory used to put a sticker on the windscreen saying don't exceed 2,500rpm until warm. I've fitted an oil temp gauge to mine, and its surprising how long it takes for the oil to get up to about 80 deg. c - at least twice as long as the coolant. I also remember something about not idling for too long because at low revs the lifters are not rotating properly, which could lead to excessive wear.

I thought it was

drive it like you stole it, or pretend it's a company car

For those without an oil temp gauge, keep an eye on the oil pressure.

If you're exceeding 35-40 psi while warming up it's a sign that you're revving too much too soon. One reason for avoiding this is that the oil pump puts excessive strain on the drive mechanism, i.e. the cog takeoff from the cam and the dizzy shaft. The upshot is excessive wear of these parts.

is it much of a job to fit oil temp gauge, whats the process? thanks again

indeedy...and as we all know, nothing handles like a rental!! So guess how pi$$ed off i was when i found out that my 'carefully cared for Ex Demonstrator' Astra was actually an ex Enterprise Rent a car as shown on the log book...DOH!!! Good old Vauxhall Network (not a) Q!! Thank god work bought it and put it on the fleet!!

I used to have an oil temp gague in my 16V Clio, as the F7P Renault engine was prone to bottom end wear at low oil temps. The guy in the renault club told me 'once she's up to oil temp, drive the nuts off her and she's happy as larry!' Worked for me!

Its is quite interesting how much longer it takes for the oild to warm up against the temp. of the water..i guess twice as well...

I fitted one of these http://www.demontweeks.co.uk/products/ProductDetail.asp?cls=MSPORT&pcode=R/PPT1014A7 

in place of my clock, which wasn't working anyway. Its a mechanical gauge. The pressure side can tee into the same connection as the original pressure sender (that stays in place and still works) and the temp. side I connected to a drilling in the base of the oil filter mounting. From there, a capiliary runs across the engine bay and through the bulkhead to the back of the gauge.

I'll post some pics. if interested.

if you could post some pics that would be a great help

"Nothing handles like a rental..."

Little known fact that rental cars are also higher ground clearance, have MUCH better up-the-kerb performance, AND theyre narrower too...

Oh the marvels... Now let me see if I can get J.R. the Avis man to get me a 'stang tomorow...

I've often wondered this myself and have always erred on the side of caution, waiting the best part of 15 minutes to exceed 3000 revs, like you would with a small engined car.

However the RV8 produces so much heat the oil must heat up fairly quickly.

My boss's V10 in his BMW has a variable rev limit based on the oil temperature, illuminated on the rev counter. I was amazed how quickly this heated up and allowed the full rev range, within a couple of miles. Surely our engines, which must be less efficient than a modern large engine, must heat up quicker?

What should the oil temp be before you can floor it and give it everything?

Quite the opposite. The water takes a good ten minutes to come up to temperature and the oil takes roughly twice as long.

[adam quantrill]

... especially if running on the rich side!

I had an intermittent temp sender so it would run _very_ rich on occasions. The water temp would stick at around 75-80 C.

Based on my normal oil temp. of 80 deg. C (non-hoon mode) I'd wait until it was at least 70deg. C.

[celcius]

i wait till coolant reaches normal level then about another 10- 15 minutres before i think of even going above 3k revs.
i do this with any car i have owned no exceptions.

Yea yeah yeah . . . I've been with you when we've been late getting up for the ferry

Process goes like . .

Start car
Get out of garage
Accelerate hard through side roads
In 1 mile be on M2
Give it the beans
Settle at constant 120 to Dover
