Hello Milesy, was it you i sold the fans to???? i can't remember?

Any how, i believe my car had a single 8", if you manually switched the fan on early and were sensible you could maintain a temperature, so 2 8" fans should be able to cool the car.... i currently have 2 10" spals which i am confident will cool the car very well. You might be able to squeeze 2 16" fans in there, one in front of the rad and one behind... or one 16" up front with your two 8" fans in between the intercooler and rad. I think this would work well.

Rob,
