My traffic and highway driving produced higher temps yesterday - peak at 205 degrees and later found out that 202F is when the fan kicks in. Had to open a small area behind the licience plate and that was still not enough so today I will open it up a little more. Definately PLENTY of heat inside the cabin.

They're not required in Florida :-) just back ones.

But yeah, the cops in your towns are quite dickish. BTW i think i might have seen you the other week. I was in a Greenish Plymouth, and you were coming from by the Hospital?

It got too warm today - 40 degrees - so I had to open up the bottom grill area and ended up getting over 50mpg on my return trip from home to office.

xB grill Block - works too well - will check thermostat for proper total sealing when cold next but the aero seems to be better.

Clean

I have to say that these are very impressively clean-looking designs.

Just thinking out loud -- perhaps a controlled air-inlet could be operated on the fly (vaccum, servo, or what-have-you) if things get too hot...

Yeah Just a piece of foam and since the air builds up in front of it anyway it just flows around and it is easy to pop out when it gets warmer like yesterday when it reached 40 degrees - I pulled the lower one out and still have enough heat from the heater and got some better aero from the top piece. The cutout behind the bottom of the plate helped a little but when going uphill it tends to heat up too much so I finally had to pull it out. I still want to make it adjustable from inside probably with a cable. That way when I park it I can close it up to retain more heat in the winter to keep it warmer longer before I go out again. Something automatic would be good though in case I forget to open it up. It was very apparent that fuel burn rates over 0.7gph made it warm up a lot and when the rate got to 1.7gph you could see the temp climb and required full speed on the heater fan to keep cool. Still need to check to see of heat/coolant is leaking through the thermostat when cold. One other thing that was nice is that by running the engine temp 15 degrees hotter it warms up the tranny more too.
Also want to make a lower air dam that can be lifted when going over stuff that would hit it to get even less air going under the chassis.

It is a very nice looking grille block; nice workmanship. But 10 mpg gain from it???
