It's certainly a funny one.

Agreed Shane, which is why I wrote the highlighted above.

It is indeed strange.

Gorilla could exhaust gas temps cause a problem at WOT?
I have read (WITHOUT PROOF)that certain engine remaps they run extremely high egt's from such a highly tuned map????could that be his cause??
A lot of fuel/timing/air mixture causing it to run hot??


Has shimmy had his car remapped??

We both had our throttle pinned. As you know Alex I have 2 throttle positions, 100% on or off. And I'm not afraid of revs. They're there, so ill use them

High egt is a bad thing and it's an effect,

The exhaust manifold as you know runs soo close to the side of the block if they are overly heating then they can transmit heAt to the engine block aiding in heating the water!!!just an idea seeing as the cooling route has been almost exhausted!!

I have the manifold on the Cossie heat treated as on track with the ALS running it can see 1100 deg C EGTs .







Perhaps it is worth doing on the CSL?

maybe there is another reason the little donkey overheats in your car?

Old engine had a couple, but removed and new engine never (still same issues)



Regarding nitifreeze, are we saying go to 70% antifreeze, 30% water for max cooling?

Thought you had the Simpson map with de limit.

I know someone who had the Evolve map, then Simpsons map, the. evolve map, then had the maps erased and a standard BMW map put on.

Not me though.

I just have a new engine with BMW map.
