Has anyone installed a WAI to a Gen I Volt?

I have one on all my other cars and gain at least 20% MPGs in the winter and gain better windshield clearing, even with the gas motor on the volt running full blast in negative 10 F temps it has trouble.

I do not see a decent way to route the intake, so I figured I would ask here first to see if anyone has made the best mod in history to the volt.


Also has anyone done the Prius like mod to trick the fuel tank empty?

Looking it appears it would be easier to not install the switch to the tank but I do not know where the wires end up front, anyone have a service manual so I can see what is tappable?

Thanx
Ryan

I don't know - what's a WAI?

Well a CAI is a Cold Air Intake. I image a WAI is a Warm Air Intake? Theoretically that should reduce performance and gas consumption (warmer air = less fuel needed).

WAIglobal auto parts company?

Women in Aviation International?

Web Accessibility Initiative?

Thai greeting?

Web Application Interface?

Come on OP what's the acronym for?

In modern engines running closed loop, I don't see how it can matter all that much. The computer adjusts fuel mixture constantly and the power requirement to run at a given speed/acceleration doesn't change.

Seriously, no clue what the OP is talking about.

Why would I want to make the Volt think the fuel tank is empty? Wouldn't that make it limp around in reduced propulsion mode and just stop when the battery is discharged?

I've done *cold* air induction systems on my vehicles in the past, but not a warm one. Generally speaking, cold air gives better performance than warm, hence why so many people use them. Increased airflow also tends to give better performance and it's another reason why they are used because people claim they provide engines with more air. However, I've also seen any number of scientifically done tests that have shown that many of the systems out there really don't do anything over stock airboxes or high flow air filters (like K&N). If they do give any increase in performance, it's so insignificant that it's not worth the expense of the systems which usually runs in the hundreds of dollars. However, people like modding their cars thinking anything they do is going to give them performance increases, so there ya go.

I guess everyones replies here answer my question.

Volt uses 50% more fuel (GPH off my guage) when the intake air is below zero, timing is pulled and the AFR is below stoich, this condition DOES NOT APPEAR TO CHANGE AS THE CAR HEATS WHEN AIR TEMPERATURES ARE BELOW ZERO.
Car also never achieves 180F to open the thermostat in hold under these conditions.
from the factory the Volts intake gradually gets up to about 20-30 degrees above ambient (takes about 45 minutes of driving),
but this doesn't appear to help when its 10 below.

So yes a WAI (WARM AIR INTAKE) is common modification (many times right from the factory) on eco cars like the Honda Insight and Toyo prius along with a bunch of foreign cars made in the 70's and 80's

I have one on a Cobalt XFE (winter only) and a Honda Insight (year round) and it made a huge difference in drivability and getting heat at the defroster.

It has a dramatic affect on cold weather performance (talking heating) and fuel economy.

In my case my volt only gets a max of about 32mpg when its below zero, regardless of whether ERDTT or in Hold.

I will have to tear off all the plastic garbage and take a look again, and post photos of it once I figure out how and what I want to route.

...and leaving unanswered the question of what a "fake empty tank trick" is.

Well, we had fun while it lasted. So a WAI was one of the things I might have guessed, but I couldn't see how it would benefit a Volt.

Most of my early cars had this, usually achieved by positioning the carb air intake close to the exhaust manifold. I don't know if or how it helped heating, but it did with carb icing, especially in cool damp weather. For heating I would install some kind of radiator blind.

I've been caught out by the 'fake full tank' trick' but never heard of this one, and especially can't think how it would help heating.
