Noise level comparison between a FI and carb engine Options

[Tdskip]

So there is a very significant noise difference between my 1.7 FM my car and the 2 L that I just drove down from Oregon. I know the cars are not identical so it’s not a complete apples to apples but the car with the carbs is significantly louder under pretty much all conditions.

I would expect an increased level of noise because unlike the FI system and the carbs are more open to the environment via the two air filters and how they’re mounted, just curious if that’s consistent with other people’s experiences?

Thanks and happy Saturday all!

Yes it is. I have had an FI 1.8 and then swapped to a 2.2 dual carb and the volume inside is decidedly louder.

Of course there is. It's basic physics. Two air cleaners put right up there are not covering up the sound.

I DRIVE A STOCK FI 2.0L AND ITS PLENTY LOUD. WHAT DID YOU SAY?

Thank you for the sweet sounds. Who was complaining???

[michael7810]

I have carbs and all I hear is the valves clacking and the sweet exhaust sound.

Its a carb noise ....
Thats the sound of simplicity and reliability and performance
(Ask any /6 owner)

So if your looking for road manners at the cost of
Stupid complexity ( in the analog age)
then f.i is the ticket

My first car had carbs, Monza exhaust and Yokohama A008’s. All 3 made a lot of sound and I grew tired of it on drives over an hour. Some people don’t mind. I did. We all have our own tolerances.

HHHHmmm,ask a six owner...ask about what? the 911 motor has a great stock air cleaner that kills most carb noise,however being a cam chain motor there is more noise which under revs makes the most wonderful mechanical noise (IMG:style_emoticons/default/wub.gif) .

I ran K&N's for a while and there was too much induction noise over and around most RPM driving range for me.
The Honda bike mod seems to work for many with 4 cyl or there is a $$$$ CSP setup which is a fine piece.

Be very careful with the Honda housings.... I've got them and they really cut the induction noise to a pleasant bass note. HOWEVER the passenger side one let enough rain water in to hydro lock the engine.... weak hi torque starter gear shattered before bending a rod. I've since fashioned a rain hat out of a five quart oil jug for insurance...tacky but effective so far. Be nice for someone to design something that looks better...

Dude, i KNOW we are going to always fight about it. But carbs are not better.
Especially if you insist on manners. Sorry my man, but just not better.

EVEVNTUALLY you will wake up and admit.

Just tell me in the movie mad max beyond thunderdome

(IMG:style_emoticons/default/hissyfit.gif) damn that sucks .

So glad my mechanic talked me outta the
Gold wing covers

I know bro, and it's ok if carbs still stuck and why they aren't on modern cars

I'm liking it all, and know we will always banter in the best of terms. Too bad you are wrong. (IMG:style_emoticons/default/tongue.gif)

wow didn't know that ,thought they were the s#it,is it water pooling @ the top cover?

[IronHillRestorations]

With FI there's a much longer path from the intake valve to the air inlet, with some significant twists and turns that muffle the sound.

Sounds like alot of guys would want a
911 esque type airbox for their carbs

Got to give it to porsche .

From the fan the airbox the engine to the muffler
These cars were almost engineered to sound
Cool .



( funny because the 2007 focus i just bought
People describe or complain about the engine being buzzy or mechanical sounding ) (IMG:style_emoticons/default/av-943.gif)

I run the cleaners that came with the Redline Weber kit and no sound complaints. I have driven a stock car with the same 2.0 and factory FI and mine sounds better. As for the FI vs carb debate I would point you to this forum. It’s been awhile since you wouldn’t find a frustrated FI owner on posting for help. Usually a couple on the top of the list of posts. It’s an old system getting older every day. My carbs are fairly new and I could order new ones tomorrow if I needed. Combined with a Pertronix pointless distributor and you have a level of reliability you will never find with antique FI. Everyone with a driver 914 should have their original FI just in a box on a shelf where it belongs.
