The variety of powertrain applications in Rotus often presents unique situations relative to heat accumulation in the engine compartment. For me it was the proximity of the turbocharger to the battery on my 2.3 liter Ford. In the following photos I show that reltionship with a "hood off" shot of right side of the engine bay. Note that there is a heat shield arround the battery which provides the 1st line of defense. I took the further step of enhancing air flow in this area by installing three "portholes" on the side of the hood (bonnet). You older folks will probably recognize the trim rings as those used on the fender portholes of the 1950 Buick. Now that's what I would call judicious recycling!

Is your hood louvered?



I will have to either get a new hood, or put a hood scoop on. My current hood has a hole in the middle for the exposed air cleaner, but the new engine has the filter in the front.



I have to look into a solution to get cold air in, rather than the air coming out of the radiator.

No louvers in my hood. I really don't like them from an appearance point of view. But to each his own. I also understand that for some situatuons they may be the only solution.I have an intercooler for the turbo charger but for that I have an air scoop below the radiator&nbsp;and the air flows in via the grille opening. &nbsp;Aside from the portholes the only other concession I had to make was a small blister on the left hand side of the hood http://www.usa7s.com/forum/uploads/redbaron/2006-01-07_090614_IMG_1412.JPGin order to clear the throttle body. It is quite innocuous as the attached picture shows.

It's definitely a clean look. I assume to cut the opennings, you started out by drilling a hole, and started cutting from there? What tool did you use to cut?

I started by cutting a 1 in dia hole with a hole saw and then, since I have an air system in my garage, cut out oval hole with an air powered nibbler and then cleaned things up with fine tooth files. I did the NACA opening in the cowl side for the footwell ventilation system in the same manner.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp ;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp ;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp ;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp ;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp ;&nbsp;&nbsp; Red Baron
