How could one reduce the underhood temps? Would products like a cowl induction hood or a set of scoops help? Opinions welcome.

I'm not sure yet if it sucks air in or blows out from under the hood. I was going to attach a bit of thread to it and run down the highway to check. Doesn't make any difference on the temp gauge.

Rob IF YOU GET A CHANCE DRIVE IT IN THE RAIN AND WATCH THE WATER DIRECTION ON THE BACK OF THE HOOD. IM BETTING IT SUCKS RIGHT IN THE BACK OF THE HOODhttp://www.dieselplace.com/forum/smileys/Big Smile.gif McRat 08-01-2004, 10:57 PM Best bet would be to blanket the "hot" parts with shielding. HP would go up as you will use more of the exhaust heat to build boost. | ||
