Daox's 2004 Toyota Prius Build Thread

Congrats - 65.3 mpg-e is your best tank yet!

Yep, it is far above my normal average in summer of ~55mpg. Its also a bit impressive due to the colder weather we've been having. I havne't started using the block heater yet, but its use is not far away.

Hello, I enjoyed Reading your forum.
Are there any updates? Forget Thanksgiving, work on your car

I was curious about the heating and cooling issues, being from Michigan myself.
I was wondering if anyone has considered running a vacuum pump instead of w/ a belt, with some kind of compression turbine possibly run from exhaust, like a turbo? The clear advantages are to have a higher pressure line and vacuum line, the exhaust manifold would have to be modified, this could then (possibly) be used to directly to heat other components as well as power the car's stock condenser. As an owner of a celica I am not sure how the AC vacuum/ compressor is/are set up and I wouldn't be surprised if you could disconnect your AC belt for increased summer driving economy.

Anyone know if a scan gauge can work with an 03 celica or what will? There are a lot of wire harnesses but I can't find any parts online for mpg meters.

A scan gauge will work with any oby2 car. So from 96 on it should work.

The only heating/cooling issues there are is since my commute is so short and I use EV mode as much as I can the car doesn't really warm up well in winter. Max coolant temp rarely hits 160F.
