I'm definatly interested in how the partial under tray works out....and the rear wheel well covers. COZX2 credits his Grill Block and rear fender skirts to a 11mpg improvement. Although I think he is assuming some engine on coasting benefit from the aero mods. So I don't think we will see this type of benefit. He also did two under trays. One under the bumper and the second extending to the back of the motor. He used a plastic sheet from home depot. The type the use on bathroom walls. He claims the extending it any further had a negative effect on the wake pressure behind the car. He also used 4 tire spats and had his lip spoiler to within 2" of the ground. |
I couldn't quite figure out the tire spats or what exactly they were.
I was going to do a bit more of a under tray than that. Bumper to front wheels. I still may. But it just didn't seem to important. We'll see if insomnia kicks in later though.
I really want to do wheel well covers but I want to wait at least a tank with improved grill block and under tray. Good thing is I have a scanguage. My goal is to get the throttle position down one. 16=0. It's usually between 21-23 highway. 23/24 is where it peaks up to regain speed in cruise. So keep it away from 24 and less 23.
EDIT. Insomnia kicked in. I put more carboard from bumper to front wheel. One side has way more tape because there was more of a gap to stock plastic guards.
