electric fan question

[Christ]

Frank - Have you ever considered putting a panel from the radiator to the bottom of the engine compartment to direct airflow downward after leaving the radiator?

I just wondered how it would affect your engine temps/mileage.

[Frank Lee]

I have never considered that.

There sure isn't much room in there for something like that either; especially in the car but even in the pickup.

[Christ]

I figure not, but are you willing to give it a shot? You don't have a grille block at all, right? So I figure that it will shunt flow a bit because the air will have to change directions, but it might also keep the air from getting in around the engine and creating the vortex under the hood... maybe help with aero a bit?

Just figured if you're willing to test it out, might be something to look into.

[Frank Lee]

They both have grille blocks (no pic of F150's though):



plus the Sport Coupe has this:



Edit: As you can see, perhaps the front end aero isn't optimized???

[Christ]

Maybe remove the grille block and test the rear panel?

I guess it won't help you with aero at all, since you have a block, but the data will still be a nicety, I guess.

Up to you, if you're willing to try it out.

[Frank Lee]

My testing sux. No consistency in my routes; no Scangauge. All I can do is hope to spot big-*** trends.

Although I am proud to say the Coupe gave me 43 mpg on my last fill and that is with NO P&G!

No, I'm not feeling too much pain from it's "awful aero".

[Christ]

Fair enough.

[Frank Lee]

Sorry to say, but the Coupe's gas log data shows fe all over the place and that is with things being as consistent as can be. I should go figure the range of the data...
