aerodynamic camaro?
hi, new poster to this forum and ecomodding in general. the more i read the more and more i am interested in aero mods. i own a 95 camaro as a daily driver and was curious about a few things. i am planning a fog light grill block, clear headlight covers, and plastic air dam and tire deflectors. had a couple of questions
do my mirrors look aerodynamic or is a passenger mirror delete in order? http://i387.photobucket.com/albums/o...8/DSC07132.jpg http://i387.photobucket.com/albums/o...8/DSC07120.jpg also what are the rear tire deflectors behind the rear wheel for in this picture? http://http://www.netcarshow.com/che...llpaper_13.htm http://photo.netcarshow.com/Chevrole...0_photo_13.jpg and lastly is there anything subtle/easy i can do to my rear end? i was thinking maybe it would be more aerodynamic to block airflow from going under the rear spoiler. search youtube for "MOV01684.MPG camaro" to see a video of airflow around the rear spiler of a camaro. this particular one has a large lip addition but i think it may still be helpful http://i387.photobucket.com/albums/o...8/DSC07114.jpg thanks for any help! |
Here is the 3rd gen thread, might give you a few ideas.
http://ecomodder.com/forum/showthrea...ree-20643.html The early body style 4th gens mirrors are pretty slick, I would leave them alone. More food for thought: http://ecomodder.com/forum/showthrea...els-23234.html It originated back around 2004 during my go fast days. |

Aerodynamically, they're a difficult area, so removal is almost always a (small) benefit. Quote:
That's a legal requirement in some areas. Quote:
If it's really a guzzler, you might keep it as a fun car and limit the miles you put on it, and get a more economical daily driver. Just a thought ... |
How about some mechanical details? What engine, transmission, and rear end gearing do you have?
I know some of the rear end gears can swap with S10s, so if you're looking for highway MPG.. |
im currently a student so i can only really afford one car and i'm not quite ready to give this up.
its a 5.7L LT1 V8, 4L60E automatic, with a 3.23 rear end |
So, biggest motor, worst transmission, and best MPG gearing they offered. Gotcha.
I have the same tranny :( Solid, but nothing to write home to Facebook about. What kind of MPG numbers are you getting now? |
my last two tanks were 18mpg 40%city and 15.6mpg 75%city
the 3.23 i have now were part of an optional performance axle package, stock they came with 2.73. how much of a difference would that make in mpgs? |
I would modify the variable that yields the greatest gains that cost the least first.
1) driving habits 2) tire pressure etc...then move to mods that cost, that may have a lesser effect. |

+1 Read 100+ Hypermiling / ecodriving tips & tactics for better mpg - EcoModder.com Then 65+ Vehicle modifications for better fuel economy - EcoModder.com Since your car is a 1995, it is pre OBDII. You can not use a Ultra Gauge or Scan Gauge mileage computer. You can however use a MPGuino sold here on this site. You would have to splice it into your wiring harness. It is not hard to do and gives you a ton of feedback. At the very least install a vacuum gauge to help you figure out if what your doing is a plus or minus. http://ecomodder.com/forum/showthrea...able-6914.html The best thing you can do to improve your mpg is... Adjust the nut behind the wheel... > |

2.73 on a V8 with Th700 or 4L60x isnt the holy grail of V8 fuel economy but its darn close. At some point I would like to go from 3.08 gears to 2.73 gears, I expect to pick up a little under 2mpg. You would see at least that. My metric for picking up MPGs is to try and stay under $250 per 1 MPG gained. By the time you bought and installed the 2.73 rear, sold your old one I bet you could be in it for less than $500. The 2.73 rear ends are toxic to the performance 1/4mile guys, they will all but give them away for free. |

regarding the mpguino, im not good at anything wiring or electronics so roughly how much would a shop charge to install it? |
With an automatic, I would assume the 2.73s wouldn't improve city-mileage due to acceleration losses. But once you got the Camaro moving at speed, they would help keep the RPMs down.
|
I would expect most of the gains from the gear swap to be had on the highway.
A city MPG improvement is possible. When I put larger tires on my suburban it effected the final drive ratio a little. I expected MPGs to go down in city driving with bigger tires but MPGs stayed the same and may have even increased a little. |
rear visibility
When backing,do you(can you) see below the wing to judge distances?
Also,in the winter,during a good snow,does the entire rear deck get covered over with snow? If so,when you drive,does the opening below the wing appear to have any effect with respect to clearing the decklid? GM is very careful about rearward vision and the spoiler might have been a compromise,balancing safety and drag reduction/downforce. |

When GM was developing the Trans Am Firebird,the Camaro 'kicker' type spoiler had the best performance,but Pontiac had to stay with the 'styling',so they used something more like what is on your car now. |
