Sorry the calc quote was from Digsy
The above spec is my spec
its not finished yet as I'm waiting on a little custom fabrication - but in my country with ambient temperatures reaching max 23 Deg C the cooling above should be sufficient
I totally agree the stock fan is the best unless like me you have a custom shroud made for the electric fans
Even then the stock fan will probably still flow twice as much as the electric fans however do we need the fan to flow insane amounts while were taking corners at 70+mph I dont think so
I still have all the oem parts ready to go back in if I find that the temp is a lot higher than the car - or I - can tolerate
