I don't know what my problem is, I'm always trying to get cold air into my engine. I keep making and modifying airboxes or heat shields trying to get cool air. When I was N/A, I eventually built a box that partially sealed against the underside of the hood and had a pipe that got air from the bumper. That one worked really well and took me several versions to get it right. Now that I'm turbo, I've tried about 4 different airbox/heat sheild ideas. Right now, I've built a polypropylene air box that seals against the hood pretty well. Only problem is there is no room to run a pipe to get cool air. I keep thinking about making a scoop in the "power bulge" in the hood to pull air in. But that would take alot of time and money. It probably wouldn't make much of a performance change, especially since its got a turbo/intercooler and 10 feet of piping to go through before hitting the engine. I really need to mount the temp sensor at the throttle body to see if cold air at the filter makes that big of a difference.
