I do have F360 installed, and it= 's not that difficult to use, but I just haven't had the time to get profic= ient with it=2E

On diffusers: I think that= the K&W streamline diffuser expects to be loaded by the core at the wi= de end=2E If it feeds a wedge diffuser, it doesn't have that 'load'=2E Blow= ing through the diffuser with a leaf blower or shop vac and moving a piece = of yarn around the core's output will tell you a lot about how well the dif= fuser is working=2E My radiator duct looks similar to you oil cooler duct, = and I had to use a turning vane to get flow at the upstream corner of the c= ore=2E
