i can no longer use my ford fan on my zetec turbo fiesta as the intecooler needs to be moved back and the ford fan is far to big

i already have a pace alloy rad but im not sure what fan to get. i have seen that the burton power catalouge has kenlowes which have new range with jet boost which is a extra cooling


what i need to no is that the CMH (flow rate) is 2257for a single 12inch kenlowe, is that enough to cool my car on a hot summers day

cheers
