On the 69 Camaro we had less latitude on the placement of the hood exhaust ducts. We spent many hours (only a faction of the options are shown above) trying to find a way to duct the 3 heat exchangers and fit inside the confines of the OEM style, aluminum, 69 Camaro cowl hood. The raised cowl section just did not lend itself to placing the large hood ducts we needed in the proper places (ow pressure zones - which helps extract air).
Then we tried an flat 69 Camaro hood and had new styling constraints for the ducts. Even the front tires themselves limit where the ducts can be on the hood - stuff 315s under stock fender contours and they begin to intrude inboard, in a big way (shown above right at "full bump travel"). I will expand on this when we finally have the new hood installed (a composite hood is being built now) and the final hood ducting design is under construction. These ducts are gonna be BIG.
The "straight on" approach for the inlet tube we used on this 69 Camaro is the cleanest routing for the intake air and should work fine here. This produces the cleanest, straightest path for air to get to the engine (only one small bend in the inlet tube, behind the airbox).
A big K&N filter is stuffed inside the airbox and it draws air from two open grills in the upper grill section. The filter element is visible inside those grill openings in the grill block-off plate pictures in that section above. An LS3 style Mass Air Flow sensor "blade" will be added to the intake tube ahead of the throttle body later in the build.
FRONT BRAKE DUCT FABRICATION
The car came in here with 2-piece 14" Wilwood front rotors and some 6-piston calipers installed up front. Well as big as those are, for longevity on a road course this car still needs some forced cooling air thrown inside the at least the front rotors. Ryan fabbed up a pair of custom brake backing plates with 4" inlets to keep these cool.
Simple aluminum plate was laid out and cut to fit around the C6 Corvette front spindles / hubs and seal to the inside face of the 14" rotor. The 4" oval tubes were made on the tubing roller and welded to the backing plates, then fitted with 2-layer, high temp, 4" ID brake duct hose routed to inlet ducts in the splitter (which I will show later).
