[QUOTE="BlackBolt9, post: 14225427, member: 36489"] I'm pretty sure you're running AI, so this may be more important to you than an open track guy. Look into the aero affects of placing the NACA ducts at the front of the window rather than the rear. For example, look at TJ Bain's camaro. Basically used the NACA duct as an excuse to place more lexan in the window opening, which reduces opening size for better aero, two birds, one stone and all... [IMG]https://fbcdn-sphotos-b-a.akamaihd.net/hphotos-ak-xfp1/t1.0-9/969856_10100685943321272_486326257_n.jpg[/IMG] Some helmets have the duct off to the side as well. EDIT: Also, if you want to run a cool shirt (yes they work in any heat), look into the MOMO shirts (used to be 986), they use a bladder held in the shirt rather than tubing stitched back and forth along the shirt. This gives more surface area to transfer the heat from your body to the water. A full MOMO (986) ice box will last almost 3 hrs in a race car that sees interior temps of around 120deg, at least from what I've seen. Just check the ice levels in between sessions if you're worried it won't last you long enough. It takes all of 3 minutes to check it. If you have to change it out because all the ice melted, it'll take 15 minutes, tops, if you mounted it correctly. [/QUOTE]
