................is knowing what they are telling you.

I've always had a water temeprature gauge on the Scoob, the one that came with it. I now have a more accurate version, a Defi.

The old one sat somewhere in the middle of the range and never seemed to vary.

The Defi, however, shows temperatures around 82-84 degrees around town, but can reach 90+ at speed or if left after driving.

So.....what's a safe temeprature for the water? And what should I set the warning at?

I also have a fuel pressure gauge, linked to the boost gauge, showing differential pressure. It sits at 3.2-3.4 bar. What is it telling me? And what should I set the warning for on that?

TIA.

 

Surely it depends on what thermostat you have? On the 205 I had an 82 degree one. This one on the 106 is an 89 degree one.

I'd have thought so long as the water-coolant mixture is correct for the time of year and operating temperature, you will have no issue?

 

Hi Jeff,

I must get round to see the "old girl" after her heart surgery...

Firstly fuel pressure, set the warning as close to your bottom reading as possible, gets very annoying if too high.... and it is telling you that the fuel pump/regulator is coping, and that you haven't induced fuel surge on a long uphill corner - like I did !

This way the slightest abnormal drop in fuel pressure VS boost will trigger an alarm, mine is 4 bar static and alarm is set at 3.9 !

As for water, Hmmmm with an uprated cap it shouldn't boil till around 110 degrees.
So once she's run-in, I'd take her for a spin down an empty motorway ( in France ) and keep an eye on it..... IMHO start with the alarm set at 100 degrees, as I'm guessing you've fitted it into the top hose as discussed.

No warranty implied with this advice

All IMHO.

The alarm is set on my car at 97 degrees (400HP Bugeye)

The usual range is 84 degrees while tooling around at constant speed to a max of 98 drgrees when idling in very hot weather or after a bit of spirited driving

Dunx: my sender is the Defi one and is fitted where the OE one WAS.

How come your static fuel pressure is so high? I thought 3.2 bar was high..........

 

Im always trying to watch 4 defis and a knocklink + rev counter while unleashing 450bhp whoops forgot about the road ahead hahaha

 

Small injectors..... so up'd the pressure to avoid running out of capacity, will be replaced during the next round of updates....

As for watching Defis, NO need ! They have alarms to warn you

dunx

 

Muahahahahahahahahahaha!

Try HEARING them at daft speeds with the rear windows down because of no air con in 40 degree temperatures?

I should have wired them to give me a small shock...........instead of the BIG one I got when the engine gave up

 

Jeff,

Defi do a bloody great big "warning light" the size of a decent torch....

You'd know when that bugger lit up, as you'd probably have damaged eyesight as a result....



dunx - There's only only Alan Jeffery

 

Ever since I had airlock issues, I keep an eye on my water temp like a hawk. It seems to move very slightly during driving. I had a new rad fitted, and the temp seems to be a tiny bit higher when travelling round town. I never saw any fluctuation when the old rad was in, does it mean the rad is cooling the coolant more efficiently?

BTW, the movement is from one cm above the third mark on the temp gauge to just below half (probably about 5% change on the dial!). Minimal really, Im just paranoid!

 

Hasn't Nathan got one for a gearchange warning light? Bright blue? When it came on I nearly sh@t myself

 

Perhaps aircon would be advisable as your next "mod"

No more silly powerful engines

Tee Hee !

P.S. I didn't drive Nathan's car quick enough to see a shift light..... so he can't blame me for his rebuild.
