Good morning Pelicanites and Pelicanitits

(not meaning for that to sound rude in any way im just addressing both sides of the audience)

Anyway i bought a book from a Pelicanite here and been reading...

The Mass Air Flow meter/Sensor on researching it i find that it has also got to do with emissions..

SO
Can it be deleted? if so what can i replace it with? as far as new technology goes? something that has nothing to do with emissions maybe a product that will only squirt the fuel and to hell with pollution?

AND
why has it got 8 places for the injection when only 6 are used, are the other 2 spares?

and my last dum question, ive taken off the injector lines on one side and about to do the other, does it matter if i put them back on in a different order?

I want to remove anything off the engine that can be upgraded or deleted if not needed

So much for keeping it stock.....but i dont care anymore i just want to make my 930 better and more efficent and am looking at any possibilities to make this happen..

Ive taken a photo of it and highlighted the part in question

Ive been quite lucky so far as i dont know the history of the car but i think the engine has been out at the least more than once for work,
So far ive found all the gaskets for the manifold spacers are new, the spacers are new, the engine sound deadening is also new, seems like a fair bit of money was spent, albeit installed by a numbskull as every intake bolt was finger tight only, the maf was held on only by 2 loose screwsa, and months ago i spraypainted around the spacers and recently when i took them off the spraypaint had seeped all the way through the spacers and head into the tunnels thats how loose the manifold was, so maybe thats why the car was low in performance? talk about no vacuum lol

keep in mind what your looking at is my first attempt at dismantling/redoing an engine, any engine for that matter, so pls dont knock it cos its still a 930

Hopefully the book you're reading is on Bosch fuel injection K-Jetronic; if not, get your hands on a copy. That mass air flow sensor is actuually the fuel metering device that determines how much fuel is injected to the cylinders relative to the amount of air being drawn down through the metering plate. You cannot remove it, period....unless planning on an EFI conversion.

Read that book on k-jetronic, it's amazing how it all works. There's also a video on YouTube - about 20 mins that's a much shorter version for the attention challenged.

well if its needed ill just paint it and leave it in there
a shame though as its pretty heavy would have been good to lose the extra kilos

Youtube is such a great resource these days, theres a German clip i think, if a fella who stripped down a whole 911 engine bolt by bolt in animated stop start motion

Rob:

The two blocked off fuel ports are a result of using a Mercedes V8 fuel head.
That Mercedes fuel head was used because it was the largest available without
reinventing the wheel.

If you don't like it there because it's too big you can always move it. I don't recommend it as it's a real pain in the a--

Looks like the fuel filter's been there a while, might be a good idea to replace it. It's the dirty silver colored thing over to the left of the bewildered character.. They're around 20 bucks or so and they usually come with new line fittings on them. Save the old ones when you ditch the old filter.

Turn it upside down and pour the gas out of the inlet side of it into something and see if there's rust particals in it. That'll give you some idea how the inside of the gas tank is doing.

Ive already done all the fuel and had tank out last month cleaned out, wasnt much ro clean rhough it was pretty smick, i had no floaties at all, i did same to oil drianed it then ran then drained again, internally clean , cant say same for the outside.

One prob though the fuel filter hose i didnt realise there was a hose within a hose and i thought id cut it to shorten it to have less play going to the wur or maf or whatever, but too late i realised should have left it as i cant join it up again, will need to replace it. so ill probably replace most of the fuel lines that are plastic and rubber with something newer, anyone know where i can get good quality/looking fuel lines?
