As the temps start to creep up here in the PacNW, I'm realizing the need to vent my engine bay is going to be real in about a month. Rather than wait, then panic, I'm going to do the work now. I figure i'll also get my aerocatch hood latches installed, too. What I'm seeing now is actually fine and dandy, but I don't think it stays that way when it's 20F hotter...
Current setup:
Ebay Scirocco radiator
Custom Radiator frame from our good friend, EHMotorsports
high-flow puller fan
Autozone Hayes pusher fan (couldn't fit two 12" pullers on the back of the rad)
Running 100% water w/ a bottle of water wetter for the summer
180F thermostat
custom exhaust manifold shield w/ gold heat tape on the inside (other Evan special)
underhood completely insulated w/ heat sheilding
So here are the assumptions I'm making:
1. Hood louvers - If just cut a hole and drop a grate into it, I'm going to increase the positive pressure under the hood, slowing the flow of air through the radiator and actually increasing. So louvers are a must
2. Doubtful I'm going to find baffles, so I need to place the louvers forward enough to catch the heat coming into and off the top of the manifold cover, but not so far back that rain can get into my valve cover and ruin my day.
Are my assumptions correct, here? Placement is really my biggest question.
Thanks in advance for the advice (whomever offers it). Recommendations for louvers are appreciated. I've got a FLIR camera and I'll track my results for the community.
