haha i couldn't think of a better thread title so meh

I know i have another thread here doing some stuff to the car but that was before i lived in a house where i could actually do things to the car!

So here's the plan... Full upper and lower grille block because it gets down to -50C here in the winter. I moved here a few months ago and installed a block heater so that's covered.

Tonight I'll be heading out to do some ABA testing of the lower grille + fog lights with painters tape before i start making something permanent.

who wants to place some bets on what i will gain doing about 100km/h? im guessing 2MPG

BTW i tested the upper grille a long time ago with some clear poly film and it gave me 1MPG (not very scientific) at hwy speeds...second pic

**EDIT**

well since this thread isnt very exciting and has no replies i thought i would just add onto this post.

this was on about an 8km stretch where i went out and back...had to throw out some results due to traffic. Bottom grille and fog lamps were covered with cardboard. No pics it was dark.


A - No Grille - 5.0L/100km - Out
A - No Grille - 5.3L/100km - Back

B - W/ Grille - 4.9L/100km - Out
B - W/ Grille - 5.0L/100km - Back

A - No Grille - 5.1L/100km - Out
A - No Grille - 5.1L/100km - Back
A - No Grille - 5.2L/100km - Out


Looks like about a 0.1-0.2 L/100km (approx 1-2MPG) change or 2-4%?

What do you guys think? not enough data to be considered accurate or does it look promising?

2-4% sounds about right for a grille block.

I assume you have a ScanGauge to monitor coolant temperature? Won't be much of an issue in February, but you don't want that radiator fan running more than it needs to before then (or worse).

Yup i have a ScanGauge

On my first run with the lower grille blocked plus tape on the top the temp climbed to 210F when the normal is 190F so i took off the top tape.

...And after seeing the fairly reasonable gains i started to construct my Semi-Permanent "remove on the fly" lower grille block + fog light covers.
