As is often the way, a lot of things got changed when i did the engine so i don't know what's done it! I removed the fan blades and fitted a kenlowe fan instead, and i also fitted a LCB exhaust manifold and a water heated inlet manifold in place of the cast marina manifold i had fitted before. The other thing i fitted was a new twin core rad, so that should be cooling plenty!
Since this, in a bid to cool it down, I have changed the thermostat for a brand new 82 degrees one, still with no improvement. The timing and mixture are correct, and no ammount of adjusting either seems to affect the running temperature. I've also refitted the oil cooler that came fitted to the car, that hasn't had much affect either!
I'm thinking my extra heat could be down to the heated inlet manifold, it certainly feels warm to touch after a long run! Would the temperature of the charge affect engine temp? or just reduce power like i'm sure i'm about to be reminded? The only other thought i had is that the LCB is throwing a lot of heat into the engine bay, in which case i'm considering 'wrapping' the manifold. I dont think the lack of mechanical fan is causing it, as it's hot when moving quickly too.
Any ideas would be gratefully recieved, or shot down immediately
