Here are a few pics of a new hood setup, it weighs 9.1 lbs. The liner is set to clear dry pipes now for the basic setup. Then theres an option of the Force race hood. A true naca intake that will duct into a cover to direct the air and any water. It will exit at the back corner just above the kawi drain and near the carbs. The cover will be like the liner with that clean carbon finish.Not shown in the pic thats the last piece I need to make. The hood just left with Jonny Smith for paint tonight. Its going on his Evo conversion and leaving for South Carolina tomorrow morning. I will get pics of the overall finished build tomorrow morning before Jonny takes off for the races.

Looks nice, the NACA duct is cool looking but gives the opposite function as what you'd really want, meaning it's a low drag inlet, not a high volume inlet.

Its not done yet as I mentioned it has to go to the race this weekend with Jonny. And from what you understand and mentioned thats what I want. A low drag inlet, which has a decent amount of area or volume in comparison to some other hood holes. There will be a scoop on top of the naca that also works as a pole pad. Every hood I have seen has a few holes that look cool but are flowing into the space between the hood and hood skin. At the same time air is trying to be drawn from the back intakes. After looking closely at some of these hood it looks like air would enter the scoops at top speeds and try to flow right out the back through the path of least resistance. Possible causing low pressure and making the engine work harder to suck air. Instead of flowing to the front of the hood. Or as the air is forced into the upper scoops at high speeds directed back as it would flow there is air trying to go against it in the opposite direction from the rear inlets. Creating turbulence inside the hood. With my hood I will be drawing air into the engine from the rear intakes and forcing air from the top staight into the engine compartment. Two separate air supplies. Like I said some of the finishing touches are missing and won't be done until the hood comes back. Thanks for the feedback its always good to hear different points of view.

You ever think about making a conversion hood like 24/7 made for SJ's?

Not sure how many you would sell but it makes the X2 guys like me start the wheels turning...
