Piwoslaw's Peugeot 307sw modding thread

[Piwoslaw]

I had a long look inside my engine bay and making a duct for the post-intercooler air won't be easy - the A/C's plumbing is right behind the IC and there is no easy way to move it aside

My mechanic is replacing my brake rotors and pads, everything got rusted out from lack of use Hopefully I'll see better coasting once he's done. Or maybe I should remove my brakes to save some weight? The front rotors weigh like 6-8kg each!

I got 10 minutes under the car while I was at the mechanic's so I started to insulate the oil pan. Only the front for now, if I don't have any problems with overheating or with the foam over the summer, then I'll add more before winter starts.

It is a rubber foam, 3mm thick, used for sound deadening. The specs say it is good between -40 and +105°C, the guy at the car audio store I got it from says that 90°C would be a better safety margin. But he also said that it is not flammable, so if it gets too hot then it'll just melt. We'll at the end of summer.

Maybe you could build a duct with plumbing left inside? Or maybe a deflector for the air to move it away from the engine?

I'm hoping that's a joke about removing brakes... I know it's heavy but if you want to save some weight you should buy ceramic brake rotors they are much ligthter, rust proof and 20 times more expensive

Nice! Oil temp shouldn't go above 90C to often but... Take a look there from time to time... I think 105C is slightly too low for an oil pan. But... With your style of driving that should be just fine. We'll see in the Summer

Nice idea with the oil pan insulation. I'm anxious to see how it holds up.

Mrs. P has gone out of hibernation after 2 years of not sitting behind the wheel. The car is now pretty much hers, I have to negotiate and beg if I want to drive. Among the good sides of this:

• She is perfecting her driving skills, and hypermiling skills whenever I'm next to her,
• Her fuel consumption is hardly worse than mine,
• I feel so relaxed not having to do the fighting on the streets of Warsaw.

A down side is that I keep the grille blocks open for when she will be driving without me. During the summer this isn't much of a problem, but when it starts to get cold I'll either have to automate the blocks, or teach Mrs. P when and how to open/close the grille. Neither will be easy

So while she is adding to Svietana's trip log, I am biking 40km daily. Part of my weight reduction plan to improve Svietana's FE

I met with AndrzejM (cheers!) a while back and had a chance to drive Bertha. Having the engine start/kill switch on the trans stick is just sooooo natural, that even now I can't get used to not having it in my car. This is the project I keep thinking about while biking to work everyday...

You just need a small rocker and the rest is just a piece of cake

I know the feeling of wanting the kill on the stick, thats where mine has been for almost 3 years now and I drive any other stick and I press the spot for the kill without thinking about it not being there.

Got a whole hour of free time () so I had a look at the foam insulation I stuck to the oil pan before summer (see top of page). It held up, no melting or any other damage visible either to the foam or the oil pan, so I went ahead and added more. I covered all 4 sides, then added a second layer (I still have enough for another 1-2 layers), each layer is 3mm thick.


Before starting I had the pad heater on for ~30min, then drove into the garage. It was cold outside, the chassis temperature was 4-5°C while the oil pan was 16.5°C, the test piece of foam from before summer was 15°C. Now with all sides covered with 6mm (compared to an isolated 3mm) the oil pan should hopefully hold temp much better.

The underside of the hood has a "blanket", probably for sound deadening but also works as thermal insulation. That's not good enough - I covered the whole underside with bubblefoil, shiny side down. The OEM blanky is still there, behind the foil.

As you can see, the old cardboard-with-alufoil-glued-to-it is still in service, but I plan to replace it with something that will better wrap the top and sides of the engine, instead of just laying on it.

What I find most amazing is that
- you only fill up about once a month, yet have saved some 500L according to the Garage
- you wife doesn't seem to do much worse @ hypermiling than you

[Piwoslaw]

After an hour's drive I parked the car and over the next 30-40 minutes checked a few times whether the hood is warm from the engine. It wasn't. Heat was escaping through the side panels and under the windshield, but the hood was cold to the touch.

Actually less often, more like once every 2-3 months. But I service my bike more often

- you wife doesn't seem to do much worse @ hypermiling than you

I taught her well, or she's a good student. Either way I'm not complaining

Try fire blanket. I'm using one in my wife's car and it's doing an amazing job. Engine is warm in virtually no time.

I'm trying now to get another one for Berta.
