On the inspection form, 3.E it says fresh air vent - enclosed vehicles - fire protection around venting.
Production class we simply have 2 aluminum flex vent tubes run from the cowl opening (stock) to the stock dash vents at each end of the dash.
We haven't installed the fire system yet, but have 2 - 180 degree nozzles for the engine and one 360 degree nozzle for the driver. This just needs an open plane of spray to reach the driver and both vents if I'm reading this correctly?
Can someone please clarify what the inspectors are specifically looking for?
Second question regarding the fresh air vents. Our hood scoop is rear opening, above the cowl so I'm worried about an engine fire venting fumes into the cockpit. I can separate the cowl so that the fresh air comes from the outer edges - outside the plane of the hood scoop? Is this acceptable? Will this pass inspection? What would it take to unanimously pass? Is that even possible?
