I'm with you Trekkor. I'd like to build a 2270 with dual singles and low compression and see how it would be for MPG. But the cam will make all the differance.

One of the stock offerings was a dual single barrel carb set-up ( Solex ).


only in europe.
only on the 1.8L.
only in '74/'75.
only with much higher compression than *any* other T4 motor for the 914.

apples and oranges as far as i'm concerned ...


- will your stock engine run with carbs? sure it will ...
- will a stock engine with a stock FI system that is in good working order run better than a stock engine with carbs? you bet ...


if you don't mind dealing with:

- cold start problems on those chilly spring/summer/fall/winter mornings
- dropping idle after a spirited run
- clogging idle jets
- rejetting on the side of the road on your trip to the mountains (or sea, depending on where you live)
- headaches on long runs from those "great" sounding carbs

then carbs are the way to go for you ...

I have to admit that sometimes having a car with simple carbs and mechanical points seems to have a certain simplicity that I really like.... (IMG:style_emoticons/default/wub.gif)

My first two 914's ( I consider the SIX conversion the third ) both had F.I., l-jet an d-jet repectively.

The l-jet killed me, and believe me, I tried *everything*. I wanted to go to Webers but that was over ten years ago and smog inspections were still required on a '75.
Sold that.

The current car had the d-jet 2.0 FOUR and ran fantastic, all the time.
I had no reason to change anyting except the points and condensor to Pertronix.

All that being said. I love my triple Webers.
Carbs are more fun and our cars are about fun.

you forgot the IMHO in your sentence ... (IMG:style_emoticons/default/wink.gif)

carbs are 1950s technology that belongs in 1950s cars ...

there's nothing like a good working fuel-injection system.
and if you really have to have intake noise drowning you from behind, you can always put a K&N airfilter on your FI engine ...

i always had the same intake noise... even when the car was stock in every other regard...

earplugs are a result of the following:
Header
Solid engine and trans mounts - vibration = loud
no sound deading....
no rain tray

always had carbs on it... ear plugs only became a recent addition with the header and mounts....

Andy: I really do enjoy the sound of the carbs and Beauty's stero is on the blink. You know I been enjoying it lately. Sometimes on long downhills when you step back on the throtel your suprised by the tone. I love it.

We've had this discussion many times. With anger usually coming soon.

I've asked this question in the last few with no answers that I can remember.

One of the stock offerings was a dual single barrel carb set-up ( Solex ).
Was there a different cam used? What are the lift and duration specs used in the various stock factory motors?


KT


I don't have an opinion but I am sure angry! Oh wait... Yeh, I don't really care either way. However, if you buy carbs you don't need you keep the economy moving.

Had them dual Solexes on my 72 bus and fought those damn clogged jets until I put of single Weber on it. (IMG:style_emoticons/default/headbang.gif) That was worster

fought it until I got sick of it and sold it.


Bought my 914 with dual Dells and fought that too. No chokes, clogged jets for a year and then located a complete FI set up to put back on. I remembered the days when 914's were new and wow, it was just like yesterday.... (IMG:style_emoticons/default/drooley.gif)

Yeah Aaron, I too loved the sound of the dual carbs....until I took a trip and then I cursed the loud noise right behind my head.


Whatever ya like, carbs or FI.. (IMG:style_emoticons/default/driving.gif) drive it like ya stole it. (IMG:style_emoticons/default/popcorn[1].gif)

yes, but it took until the 50s to perfect them. they haven't evolved since.
you don't fix your car using stonetools, do you?
(IMG:style_emoticons/default/confused24.gif)


and for trekkors confusion, the carbs on the '74/'75 euro models were not offered because they were superior, they were offered because, like some of you, some of porsches customers had trouble getting their mind out of the automotive stone age. (IMG:style_emoticons/default/wink.gif)


and joe, i like the sound of my car very much as well. and i have FI.
i have had a warmed over 2.0L with dual webers in my car.
honestly, my current FI motor sounds at least as good. no rain-tray and GT lid does wonders for "sound". no need for carbs ...
