Had fun at Snett yesterday

[glendog74]

Nice vid mate - it's nice to see the track this time

[shimmy]

What oil temperatures were you getting yesterday, as it was scorching hot!

Oil up to 125

water after 5-6 laps was getting above last mark but before red. My carcwith map, diff etc prob would suffer more with the heat than standard car

although fan was running when engine on I did notice my dan would not run when engine off -ANY IDEAS GUYS?

He was tired? Who is Dan anyway

Did you have A/C on as the fan will run when pressures rise, more so on hot days, could have just been this.


Worrying your water temps running high, mine does not budge even in v hot track days and on your vid you did not seem to thrashing it so to speak, going fast but neice and smooth so I reckon you have a problem again shimmy:whistle:

Depending on your fuelling it can cause temps to rise. Get your map checked. Leaning out can obtain power but also raise combustion temps due to det, which if timing/vanos is played with can occur. Caused by ignition advancing in many cases.

Engines that have too much det tend to over heat because of the heat transfer from combustion chamber to cylinder head and then to the coolant. It starts to overheat. the hotter the engine the more it dets. More det more it overheats. Snowball effect.

As I say my coolant temp does not move.

turning off ac certainly helped as keep forgetting i had it on

mine always ran 3/4 on oil and water on track but wil get it checked

My oil gets up to 125* but my coolant stays at approx 12 o'clock and does not budge all day, even out for 20 min stints.

I know all cars are different very slightly but you would think they would be the same and run the same temps. I cannot see how the lack of A/C on my car would make it run cooler. (thinking out loud)

I do think something is amiss with yours as the rising coolant temp is not good shimmy and could cause you another headgasket to go or worse.

.

the a/c rad when working has got to be chucking out heat right in front of the main water rad so gonna rob some cooling capacity - but would only matter on the limits of the water cooling of ever reached

[3wheels3]

Water temp straight up at 12 o'clock all day here.

Your pusher fan might not be working.

[shimmy]

Your pusher fan might not be working.

Is that the electrical one on the front of the rad?

[shane@mbtech]

Your pusher fan might not be working.

Mine only has 1 fan, the viscous fan and this only works below 5mph,

So its 100% not your fan shimmy.

I know its not the fan when moving but as a seperate issue shouldn't a fan be runniing when the engine is turned off and it's hot?

Isn't a viscous fan powered by the engine?

[shane@mbtech]

Yeh it is Nathan, but once above 5mph the air blowing through the rad is greater than the air that the viscous fan can pull through it. :thumbs:

It depends on the temp the ecu is seeing and it then decides if it needs to run after switch off.

[shane@mbtech]

If you stayed out for 10 laps would it reach the red?

Did they deck the block when they replaced your head gasket?

Or it could just be a simple sender issue. Best to get it checked out though to avoid meltdown
