Using small fans w/o shroud is better as they will free spin when off at speed.

That looks much better , more refined .
It'll carry over the theme of the grille nicely.
Yeah. Now I just need to find a way to turn them off and by speed.Using small fans w/o shroud is better as they will free spin when off at speed.
A momentary open on/closed off mounted to a bracket facing forward into air stream which is engaged by a flat hinged panel as air pushes it back onto the switch shutting off the fans.Yeah. Now I just need to find a way to turn them off and by speed.
Interesting idea! I'm not sure how that would survive in my climate though....but definitely something to ponder, thanks!A momentary open on/closed off mounted to a bracket facing forward into air stream which is engaged by a flat hinged panel as air pushes it back onto the switch shutting off the fans.
Yeah, that's the simplest route and probably what I should do. KISS, right?Just use a temperature sensor. At speed, the coolant temp is lower. When in traffic or stopped, the coolant temperature will rise and turn on the fans. Also, after or during a hard run, regardless of vehicle speed, the fans would kick on to help cool down the coolant and hence the air charge.
Sorry I'm so slow o reply. had to finish the alternator upgrade. We loaned the Subaru to Daughter in college, and Wifey doesn't like driving around wit a solar panel array on the roof. It worked, though.Do you have any pics of the screens you put in your grill?
Thanks for the pics, Dave.Sorry I'm so slow o reply. had to finish the alternator upgrade. We loaned the Subaru to Daughter in college, and Wifey doesn't like driving around wit a solar panel array on the roof. It worked, though.
It's been a while since I did the grille, I mentally mixed the motorhome and Burb grilles. The Mohome has the 1/4 inch backing the Burb has a wire shelf from a refrigerator cut in half and joined in center to match the angle of the grille. In front of that is 1/8" heavy screen, then the window screen in front. The snorkels just have the 1/8". AAAAnd then below the bumper is my prototype air dam that is still waiting completion. Increased mpg by about 1/2 mpg and aids in cooling. You may notice the well drilled grille.
Interesting mind exercise, but you would need to move at least 1,000 CFM of air through that (which would make the unit dissipate way more than its 30,000 BTU rating with those two small squirrel cages that most likely put out about 125-175 CFM of air flow each) to shed the heat picked up from the air/water exchanger. That is essentially what Nate had with the old mounting system with the pair of shrouded fans, about 1,000 or so CFM of air flow across that small radiator.
Excellent work, I'm looking at using aluminum to extend my grill if needed similar to how the HMMWV's front grills were modded.Ok the grill insert is done - well, except I'll probably take it to work and weld the connections a little bit more with a TIG welder to get them fully welded and keep the weld small. It fits pretty nice.
Next I'll be adding the trim around the bottom of the "mouth".View attachment 49436View attachment 49437View attachment 49438View attachment 49439View attachment 49440View attachment 49441
Yeah, it could technically work, it's what Husker said....it's all about BTU dissipation. I looked up the heat exchanger I'm running and it doesn't have a BTU/Hour rating, just a horsepower rating. This one is rated at 1200 horsepower. I chose it because it was so oversized, I figured it would help to oversize it since it was in an inefficient mounting location. Too bad I don't have an IAT gauge hooked up, because it would have been really interesting to see if it made a difference to my IATs.I wonder how well an old school heater core and squirrel cage fan from something like the rear half of a school bus would work for the radiator?
If a second one were boxed in and given the job of air cooler with hose and pump between, would it be enough?
