I have a Subaru WRX turbo conversion with a Renegade Hybrid radiator kit, today I was driving it in Phoenix during a 109 degree day, and it started to sputter and run a bit rough. I opened the front trunk, the fuel tank was so hot i couldn’t touch it. I am guessing the radiator, AC Condenser, and fans are blowing the hot air directly onto the tank. Has anyone done any shrouding to direct the air out of the openings on the side of the trunk.
I know I have seen pictures of this, just can’t find them. Anyone have any pics? Thanks Ed |

Post some pix of your front trunk.
Do you already have exhaust vents in the wheel wells? If so, you may need to fabricate ducting to the vents - aluminum sheeting, fiberglass or carbon/fiber (IMG:style_emoticons/default/confused24.gif) |

You mean like this? http://www.914world.com/bbs2/index.php?s=&...t&p=2500558
Before you go this route try reducing your intake area or increasing your exhaust area. Intake area should be 20% smaller than exhaust area. Also be sure the gasket on the tank bulkhead is intact and making contact against the lid. You don't need a large opening to cool a Subaru. I run AC and look at the size of my opening.  |

I run AC and look at the size of my opening. Here is my trunk opening. This is the first time I have driven it with the temps this hot outside. The AC blew cold, maybe add a heat shield and see if that benefits it. Or, just not drive it when it is this hot  |

Hard to tell from that pic but it looks like the opening is too large. Try reducing it a little with a piece of cardboard or a piece of scrap metal to see if that helps. Also, you can measure the holes and determine the area of each in square inches.

Thanks, I’ll measure it and see what I get |

Out the top, best way to vent the hot air:
