What mods/fixes are you planning?

I'm not talking bigger, I'm talking anything. I dunno if bigger or smaller or lots of bends or what does anything to MPG, no one really does.

Well, we know that a plugged exhaust would be bad for the car, FE, and for emissions.

A large exhaust allows free flow at high rpm, but high rpm is generally bad for FE and burning more fuel obviously bad for emissions.

A little backpressure is good for low rpm torque - good for pulling away from a dead stop.

The OEM setup is sort of the ultimate balance between FE, performance, and emissions control from what I understand.

An exhaust test for FE would be, pardon the pun, a fairly exhausting experience I think.

There have been a few serious mpg people to claim a 2 or 2.25 pipe up from a 1.23 or 1.5 to increase FE.

i'm afraid to start a list of planned mods. i don't want to get carried away. but let's start with this:

- get the deep-cycle battery in the car before i damage my starting battery with the alternator-optional mod

- finish permanent grille block

- belly pan experiment/permanent belly pan

- clean up my kill-switch installation. it's duct-taped to my shifter and the 80F temps a couple of days this week had the inside of the car cooking - the adhesive got gummy and the switch nearly fell off.

SVO has already told me to "get off my old lady" and get on my 5-speed conversion. Perhaps I'll do that in the next few weeks.

lets see...

-wheel allignment/balancing
-Get a hotter HAI
-rear sturts
-GET A DIFFERENT CAR (my tranny has been slipping and is starting to scare me)
-coroplast underbelly at the rear

It'll be a race. Hopefully I can do mine at the shop after hours,

Well, to achieve 40 mpg in the Automatic:

-Grille and partial engine bay / undercarriage block (not entirely for aero, but to trap heat mostly)
-New tires when these get down to near-zero tread, or when I scare the crap out of myself on a rainy roadway (thinking Michelin Harmony)
-Perfecting the driving style and coasting
-Maybe some aero mods, but my FE losses are the most in city driving
-Wait until this car wears-out and get a much more efficient one (could be years...stay tuned)
-Advanced: A controlled split cold or hot air intake system for emergency power on-demand or autocross
-For the TL: fix the CAT, trick the ECU or sell it (sorry :-()
-Buy a "ForkenSwift" from The MetroMPG Company ;-)

Horah for the chevette, I have 3.
