I know its warm today but my cars temp runs normally 3 quarters md today was nearly touching red

Its a 1275GT thats had a stage 1 kit before I purchased him so I believe its 1293? Does this sound normal in that it will run hotter?

Not really, however, before jumping to conclusions, can I suggest checking by another way, what the actual temp of the engine is. So many 'hot running' engines are only a bad reading gauge. It happened to me a very very long time ago and after spending around a year and doing everything including an engine re-build (not because of this) I 'discovered' to my annoyance that it was the sender in the head.

A "Stage 1 Kit" is normally an exhaust manifold/inlet manifold bolt on swap with no modifications to the head or engine block. e.g.

If your engine has had a rebuild and new oversize pistons installed it may well be a 1293cc engine now.

 

I like my mechanical temp gauge as it gives a numerical value for the temp and has no issues with senders. I checked mine against some boiling water and a calibrated thermometer so I know it's accurate. 

Does your heater (if you have one) also blow very hot when the gauge reads high?

Is the top radiator hose getting hot and thermostat opening OK

Gazza01 legs were burning!! 😁

Timmy850 I had the heater on as I know that helps with minis but I didnt notice the heat coming off it being that hot but I wasnt really paying attention to it in that I didnt put my hand over to test...think it was just blowing warm.
I have the receipt from Mini Sport on the work they did so I need to have a look to see if it was a rebuild -

Oh I have just looked and shows 1293 Stage 2 Short Engine built - not really sure what that means. As I say Im def more a driver than a mechanic...that bit is all new to me. Few other things to do with head gasket on it also. Work was done in 2014

Is it full of water/coolant? That's the first thing I'd check.

 

Next up check to make sure the fan belt is tight.

 

Then check thermostat operation.

 

Lastly, it could be a bad waterpump, or a partially clogged radiator. Since both of those require removing the radiator, it's a good time to send it over to the local radiator shop and have it cleaned and checked. Or for about £45 you could buy a Chineseum aluminum rad and simply replace it. Over here in Kansas we get temps over 40*C and with one of these rads I never run more than the normal mark on the gauge, where I used to run way up the gauge on a hot day on the interstate with a stock rad.
