I would also love to see what kind of mileage they get from that header/exhaust combo.

Unfortunately they didn't test mpg after every mod like they normally do with a dyno after mods. I have a feeling they didn't because it would've been worse (lower velocity). It would be a good suggestion for future projects though, especially since they do have the mpguino.

I don't think they want to do it because they will be making a lot of dyno pulls for their hondata unit. I doubt a lot of dyno shops will be offering them a whole day dyno for free.

Me personally I found the articles interesting, especially how light the car weighed stock. And here us mustang guys are happy to be weighing 3500ish compared to 4,000+ in challengers and camaros. I could get like 60 mpg with a car that light even with 420 hp. Wow!

As far as off road parts, it doesn't mean you can't drive the car on the street. It means that they either don't pass emission testing(which some states don't have) such as cat deletes, they make the car too loud(aftermarket exhaust), or have not been tested by the iihs or nhtsa for crash worthiness(carbon fiber doors, bumper support bars, etc that are made for lightweight and racing) however many cars are driven on public roads with no issues

There are a lot of interesting bits in the articles, like the fuel injector service. I'm like to see some A-B testing for that. That may not be the simpliest procedure, but there are tons of little tune-up items that can do a lot more for the average joe than aeromods and the like. People need to get their car running as good as stock then worry about improvements.

I had forgotten about this with my shift from performance-building to mpg-building. I'm glad they they reminded me.

The injector service can be done DIY. I used to have a side business with injectors. For most people here with a 4cyl the $25/ injector is cheap and easy, but if you find yourself doing this more the once, or on a larger engine, this is the process.

All you need for basic cleaning:
-Ultrasonic jewelry cleaner
-Fill with carb cleaner
-new o-rings

Level 2:
-Junkyard injector pigtail (99% of injectors use the same pigtail)
-Momentary switch
-12v source
-know if you need a ballast (hi v lo impedance), can source from junkyard or radio shack

Level 3 (what they do)
-disconnect fuel rail once /\ is done.
-key on, use level 2 switching
-fill a measured container to fixed amount, using stopwatch to time
-divide time / amount

I used to do this with 20+ injectors to get the most balanced set of 4. Guess i need to start searching for comparable injectors....

Part 4 belly pan, LRR and WAI

I thought WAI's were kind of "speculative", except for perhaps faster warm-ups ?

It seems to me there are a lot of mistakes in understanding on this round of mods from them. A larger contact patch will have greater rolling resistance than a smaller contact patch. And a HAI/WAI does not leanout the fuel mix, which the ECU will keep at stoich by reducing fuel,but will instead reduce air pumping losses through the throttle by requiring a wider-open throttle to achieve the same power. Last, whatever happens to swirl air in the intake tube is not relevant since all that air is about to be dragged through a filter.

They should see benefits, but their explanations about why will be wrong, if what I have learned here and thruogh other reading these last three years is correct.

The reason to use a turbo for FE, is to be able use a smaller engine than the vehicle normally had.
What was the result after all they did to this car?
