hey guys.. weather is warming up again and i still have cooling system woes and nothing i do seems to solve it. Ive tried various things and nothing seems to work :S
currently has
RB30E fan hub
RB25 neo fan blade
shroud
brand new GTR calsonic rad
new water pump
new thermostat
good coolant
problem was huge at an event just gone.. was 30+ degrees and with just one lap (drifting, lap last 30 sec's tops) temps go from 85 degrees to 110 and oil temp around 100-110c. if i run the water squirters i have for the cooler/rad it comes back down to 100 but no lower. then if i do a few more runs it just gets real warm and coolant sits at 110 and oil at 110-120 :S
cooling sys is bled and head was off not long ago and checked for issues.. none found and MLS gasket and ARP studs fitted and reinstalled. havent had an issue lately due to mild weather but yeah even then with extended runs the temps will climb.
thinking about chucking two thermo's in front of my intercooler to force air thro them and the radator. only thing i can think of is that because tghey are close together then the clutch fan is finding it harder to draw air thro.... but im open to suggestions.
