Season's cheer to all! Hope everyone is or is going to enjoy a well deserved rest over Chrissy.
Right, straight to the point: I'm looking to fit bonnet vents to my 3RB. I'll be fitting a custom radiator from PWR over the break and wanting to avoid the potential heat wall between said radiator and the front of the EZ30. I've designed vents out of 1.0mm 316 stainless sheet metal to fit into these gaps in the bonnet's support layer:
They will end up looking like this, somewhat (it's a image mock-up so not necessarily perfectly to scale):
The key difference between these vents and other similar ones on the market are that they will have a wall that holds back the insulation (so it can be maintained to preserve the bonnet's paint) and strengthening strakes that give them rigidity and vandalism deterrent look. (Zoom into the second image). The final weight of each vent will be about 300 grams, including powder coating or painted finish.
These vents will fit all Gen IVs. So, whilst not my primary motivation, and given that I couldn't find something to simply purchase that I could just fit, I'm curious to see if anyone else would be keen to purchase such an item for their Gen IV?
I will update this post once manufacturing quotes come back, but I'm fairly confident I'll be able to offer them as a pair for considerably less than what you could find similar items online.
