Overheating on track only

This is installed on the 328 also and she never overheats.

Is your electric fan installed in same position as Ali M's?

Have you any closer pics of the wiring you did?

So my understanding is correct with no aux or viscous fan but with 16" moshimoto fan you can use car as normal, AC on idle or on track?

just run an open hose through it to clear it out, the fins are quite fragile to even trying an air line on it

but you are correct, AC will still function fine with the above mentioned configuration

Said this many times before on here.

...or just do as Alex does and be prepared to not use AC unless moving.



Issue was probably having the big AC/AUX fan blocking flow but then double hard on the system also running AC.




Should be sweet after that. Was using all the rev's at Nurburgring last week, not having to lift off/short shift

That's why I asked before doing it

Awesome. I am looking at Kenlowe fans aswell

Have standard exhaust but thought you may be interested n the temps during a track day at Donnington.

Ambient temp as recorded on the on board computer 31.5 deg C
Water temp. Dead centre and needle did not move
Oil temp, just below 125 deg C

Air con was set at 17 and did not switch it off

I started this today...





Had trouble removing the viscous fan so might have to make a removal tool

[khooni]

per Simpson, even though AC was removed on my CSL, they left the AC fan because it would switch on above 90C and in their opinion would be more beneficial than taking it off although like in a non ac car.

I have also installed a brand new oil cooler because the oil one was shot and oil temps got to 125C on a spirited run although the water temps never increased beyond the middle. Will be out on Brands 10 nov to see how well it copes.

Non AC car only has viscous fan.

[derek]

Never had temp issues with csl on track, m3 oil and water temp high, fitted oil divertor value, motorsport thermostat and viscous fan car has no temp issues now. Cheap fix.

Looks interesting
