Me and my Previa

"Neighbours" in a way: I live on the far side of Warsaw (Falenica), but I'm in Piastów about once a week (sometimes weekends, sometimes weekdays), though usually by train and/or bike I'll let you know next time I take the car there (no sooner than January, probably), maybe we could meet somewhere in between?

I count on that! And yesterday I got an idea to change radiator completely for a bit smaller one. I have two of those in my garage. It will be much easier mod then because I have both of them with fans already and what's the most important switches to turn fan on if the temp will go too high.

And regarding our meeting I'm on! Just let me know when and where and we'll think of something. Maybe someday afterhours in Warsaw?

One more mod you may want to try, if you haven't done so already, is a Warm Air Intake (WAI). Taking air from the warmer engine bay, instead of from the cooler outside, makes a petrol engine consume slightly less fuel.
Check your intake first, as it may already be a WAI.

I know of WAI but it's not that simple with Previa. It has engine in the middle and air intake under the bonnet. So to grab some hot air for the intake I'd need to use pretty long pipe, then hot air won't be so hot anymore if it has to travel from the engine to the front of the car, then go back trough another long tunnel to the intake. But intake mainfold is pretty long, it's made of aluminium, and it's placed above the engine so air entering the combustion chamber is pre-warmed anyway. My plan is to insulate engine a bit more so it will run slightly warmer than it used to. Hope it will help my FE.

Very good mpg for a van. Dont see those Previas around much anymore

Hopefully I'll go higher with my mileage

And sadly it's true you can't see first gen Previa much often...

Hi All it's me again. I'm preparing to my next long trip with Previa. In a meantime I've installed LED DRLs, and criuse control as described here diy "cruise" control (cable actuated throttle lock)
Today I should finish installing MPGuino, because I want to see when I’m burning too much fuel and when I’m saving it. Hopefully I’ll be able to post some pictures soon.
I’m planning some simple and very fast aero mods before I’ll start my trip. So keep your fingers crossed. We’ll see how it will affect FE.

Can you post pictures of your cruise control throttle lock set up? I am trying to get an idea how it is set up.

That would explain why the idle rises at idle on a cold day when stationary after the engine has warmed up. Is it fair to say the engine is over-cooled?

I would consider a grill block on my mum's Previa, but she'll probably only have it another 6 months.

It's good to see the work on your Previa going along. Let us know how the MPGuino is working.
Good luck on your trip!
