5 min radiator block aeromod

OK - It's cold outside, but I want my engine to run a little better in the winter.

I have been very busy lately, so I did a VERY fast and dirty radiator block.

Width of the radiator was almost exactly the same as some scrap (got it free!) coroplast I had kicking around.

I shoved it down the front of the radiator, and cut off what stuck out. Friction fit right in there - no zip ties needed.

The coroplast sheet is not actually in direct contact with the radiator, it is a centimeter or two out from it. (Trying to NOT melt the coroplast)

Will this this radiator block make any difference of aerodynamic drag? A little bit? Just curious?

I don't have any way to check fuel economy other than dividing trip odometer by gallons at the pump.

I have also started plugging in my block heater at night. It runs just over 500 watts, so it's kinda wasting electricity if I run it all night. I am planning on setting it on a timer, but am still looking around for it. I have one here somewhere....
