Another secret, make a good solid airpan when using the cowl hood. Make sure it is sealed tight against the bottom of the hood with some thick foam that wont let air pass through or break its seal to the hood. LOL duct tape works great, just doesnt look the best. UMMM, if you can find the Sterno gel burners like they use to heat food in catering lines, you can rub some on the bottom of the hood, it makes the air passing through the cowl cooler. This may sound extreme, but lets just say been there done that. What oil are you using?
