[QUOTE="d4ngerz0ne, post: 743944, member: 45572"] So, update. I manage to get my hands on a 18" kuih pan, about 4-5" deep for Rm30. It fits really snug, which is much welcomed. First order of business is to trim it down to about 2" deep. [IMG]http://i.imgur.com/Y5NvYZv.jpg[/IMG][IMG]http://i.imgur.com/Ad715CS.jpg[/IMG][IMG]http://i.imgur.com/z5Y6U5W.jpg[/IMG] [IMG]http://i.imgur.com/G3wBGQS.jpg[/IMG] After trimming about 3" off the top, it fits flush with the top fan shroud guard. That is pretty much the furthest you can go with your cake mount as this is also where the nearest side of the fan clutch to the water pump would be. [IMG]http://i.imgur.com/GqHmwts.jpg[/IMG] Then i proceeded to make an opening , about 15" in diameter for the fan opening after determining bolt positions for the fan. I had to grind the edges of the fan as it would fit properly inside the pan. No big deal though. [IMG]http://i.imgur.com/UCjh4g0.jpg[/IMG] As i found out later in my build, my mishimoto doesn't seem as slim as what others have used. This was causing clearance issues between the water pump position and the fan. So in my quest to fit everything properly, i further trimmed the pan so that it will be more recessed into the fan shroud , and at the same time reverse the fan position to be towards the radiator ( remembering to change fan blade direction too) [IMG]http://i.imgur.com/5BY5vkt.jpg[/IMG] Current fan-pan position is held with masking tape until i can find the time to do another mock up by removing the fan clutch. [IMG]http://i.imgur.com/yyXBGhX.jpg[/IMG] While I had that sorted out, i used the excess material from the pan to make a plate mount for my PWM. Heres the cardboard draft. [IMG]http://i.imgur.com/7vAvba9.jpg[/IMG] First trial fit . [IMG]http://i.imgur.com/0RRlmPu.jpg[/IMG] Voila, it fits nicely. Secured with M6 bolts + washer + loctite (final install) I manage to test the fan by just hocking it up to the car battery and it is as VERY quiet at full speed. very pleased Next up, wiring .
