DGV air horn?

very nice but, you'd have to make your own soft sock-filter as space

between that and the hood is very limited.

Great for your vintage Formula Ford

Hehe..=)

The on page text does say:

AIR HORN FITS WEBER 32/36 DGV DGEV 38/38 DGEV DGAV. TESTED ON THE PIERCE MANIFOLDS SUPER FLOW BENCH SHOWING AN IMPROVEMENT IN AIR FLOW. CAN BE USED WITH MOST AIR FILTERS.INCLUDES ALL INSTALATION HARDWARE. INCREASED PERFORMANCE

I doubt it makes any noticeable difference, though. Just curious. If there´s another german pony to round up, I´m in.

will this improve flow into the carb? yes. However, you would need to make a proper airbox that surrounds it and supplies it with a large volume of cold clean air.

The only problem? the hood being in the way. I have done a lot of studying on induction and exhaust systems and the truth is that the weber 32/36 or 38/38 with a stock air filter assembly would make more power across the board compared to the pancake filters that many of us run (I'm guilty of this myself). The problem is that the filter area of the pancake filter is far too small and it sucks in warm air. also the sharp edges between the bottom of the filter and the carb inlet are terrible for air flow; lots of turbulence and loss of power because of it. Hard to improve on that though considering the space constraints.

Long story short if you want the most performance out of a downdraft weber on our cars, get an adaptor and run a stock air filter with a snorkel that pulls in fresh air from the front. The extra intake runner length will help with the torque down low which you will notice and the car will pull more evenly across the board. You just have to look past the aesthetics and also you sacrifice that glorious induction noise. A bit of a tangent here but, Interestingly, a defining characteristic of a well designed resonant airbox is that the intake falls almost completely silent at the RPM that the box resonates best at; the very same RPM where the induction system is producing the most power.

I thought this was supposed to be fitted inside the kind-of-stock-weber air cleaner, which at a glance might work, just smoothing out the mentioned rough angles achieving a smoother ride for the air with less turbulence.

The height should not be that much of a problem, it hardly seems higher than the choke flaps. And they don´t reach the hood..

But, seeing that logic and assuming it would have an effect on the air turbulence, this would be a good idea also inside the stock air cleaner mounted on a 32/26. Right?

I´m not convinced this would make a 47.95 dollar difference, though=)

My thoughts. I have a sync-link installed 32/36. I absolutely love it. And after having experienced it (sync-linked 32/36). I would not run a 32/36 without out it. My opinion.

Anyway, just for boo-boos and giggles I just got off the phone with pierce manifold. I ordered that air horn. I had never seen that air horn before. I paid $47. and change...Can't wait for it to get here.

Thanks for the idea.

Ha ha-

figures.

If it's expensive, looks sexy, and seems like it will make you faster

odds are that it won't.

Disclaimer...This my experience on the practical hands on application of the said product...

I'm not making any recommendations. This is just my experience.

Follow-up the other day Thursday I believe, there was talk about the DGV air horn. I had never seen it before. But, I liked what I saw, and to me it made sense....Plus, Pierce Manifold sales and develops great products.

Anyway, I ordered one on Thursday, they shipped on Friday, and I received it today (Saturday, that was fast BTW). I can say I was so happy to see it in my PO Box. Well, with this excitement I went out into the Post office parking lot and put the thing on..

Here's the stats.

I have a 32/36. It is sync-linked. I do not run a filter element (my choice) and have not for a looooong time. I really enjoy my sync-linked 32/36 I would never go back to an un-sync-linked 32/36...why???With such a marked improvement on performance...again this is my practical experience current..

Anyway, so I installed the air horn just as pictured above. Again, I love my sync-linked 32/36..Now with my air horn installed I am head over heels in love with my sync-linked 32/36.

There is a marked boost in performance. I like the pedal response even more than before. I think based on my current experience with my set up that the air horn is a nice to have gadget...

Again results may vary....

Just a P.S. I have tried a custom cold air induction that ran from my 38/38 to the front grill of my car. It was super. However Ia remove the entire filter element (my choice) the car responded tremendously..

...like Mr. Natural says - " if it feels good - Do It! "

now if i still owned a 32/36, this would be on my throats :

3890.JPG

This aluminum velocity stack fits 32/36 Weber

Carburetors. Dyno tests show increases of 1.5

horsepower or more on both FF1600 and

F2000/S2000 engines. Stands 3.25 inches

above carburetor top plate surface. Requires

removal of cold-start choke assembly. No

provision for air filter mounting, but we

offer a very low-profile Custom Screen

Air Filter just for this airhorn

(Part No. 3894-DGV, sold separately).

Dimensions:

Carb top plate surface to top of airhorn: 3.25"

Carb top plate projection (highest point)

to top of airhorn: 2.625"

Length at top of airhorn: 5.25"

Width at top of airhorn: 3.375"

3894-DGV.JPG

This compact, low-profile filter is designed just to fit

our Weber 32/36 DGV Air Horn (Part No. 3890,

sold separately). Free-flowing gauze mesh is

sandwiched between two layers of stainless steel

screen. Flexible silicone base is contoured

specifically to fit our 32/36 DGV siamesed

airhorn. Requires less than one inch of clearance

above the airhorn and adds less than an inch

to the girth. Perfect for use inside close-fitting

bodywork or air scoops. Sold individually;

one filter covers one air horn.

Good morning C.D.

I like that suggestion...I would even say I like that idea better than the Pierce Manifold air horn...

It looks like a better long term idea.

Thanks for the head's up.....stay tuned..
