efi New Jenvey throttle look like webers

[NickVyse]

what a cracking product at a good price - reckon these will sell like hot cakes on a cold day. Such a new product I can't see it on their main web site, just their Facebook page:

That's nice. I tried to fix your link ->

It's kind of performance version of this one ->

(Slight hijack) Anyone running running one of the downdraft Weber throttle bodies with built in injectors yet?

(just realised that this was what Tommy also linked too).

Damn..... Anyone wanna buy my freshly rebuilt DCOE 40's?! This looks like such a rad retro, but modern option! Keep the old-school look, but have the extra power/tuning ability/ economy of FI... I want.  I want badly.

Simeon - 

Not on a 2002.  

Porsche and VW guys run them all the time.  Its one of the quickest paths to changing a carbed car to fuel injection, and they look period (and sexy). We used to modify the Webers but these days you can just buy them.  Same with PMO.

 

The downside to using a set up like this (either side draft or down draft) as opposed to an intake and plenum setup is that the throttle bodies make it harder to get a stable MAP signal.  Its not insurmountable, but it does add a level of complexity - especially if you have a lumpy cam.

 

Actually there is another downside (that is a possible up-side for some) - noise.  This type of setup is louder then a plenum setup. Can be a pain for longer drives. A lot of people like the sound of carbs howling at 4000rpm though, and these throttle bodies will do the same.

Nice!!  Yes...those are probably in my future.  I wanted the look of siderdrafts and the performance and tunability of EFI...BAM...there is it!  Yes I know carbs are tunable...but I'm also a techie guy so new tech is fun...

It is certainly a neat option and should help some people.,..

 

 

.... but I will keep the carbs.

Just curious...why?

I've often wondered why no-one has tried using a TBI unit from a late 80s (don't laugh) Horizon/Omni or a Chevy/GMC compact pickup truck.  Engines are about the right size (Omni/Horizon is 1800 cc; trucks 2.4 l) , and if the bases don't match our 2 bbl manifolds, an adapter--or re-drilling the manifold is certainly easy enough.  

 

I realize that TBI isn't as efficient as port injection, but it would be a much easier conversion for a car originally fitted with a carburetor.  And it would look stock, especially buried under a factory air cleaner.

 

Comments, anyone?

I would imagine because you just have to add fuel - no brain, no sensors, no wiring, just a cool carb doing its magic. 

[Simeon]

You should ask 'why' to people who still want to build blow- through turbo engines but they still do.

 

People understand carbs and carbs are not the limit on performance (in general).

Nick's largely correct.  I just like the analog function of the carb.  Swapping little brass jets to change the setup, rather than clicking buttons. 

 

On a design/engineering .... when it comes to a mechanical object, I do not like for something that is specifically designed to pretend to be something it is not. It is along the same vein as a fake "skeleton watch", or fake "slip-on brake caliper covers", or a "styling vent" that leads no where.   You can make something pretty/elegant all you want, just don't falsely reinterpret its function.  In my opinion, if you want to go fuel injection/itb's, then own it!  They are sexy in their own right.

To those of you who have installed the Weber 32/36 carb: did you have to replace the intake (Solex-) manifold or do the Webers fit directly onto the current one? If they fit without replacing it, this would mean that the webcon unit fits onto the stock manifold, too and could also replace the Solex carb, not just the Weber.

 

As far as I could measure, carb and manifold have got a fixing figure of 46x92mm- correct?

 

I'm seriously thinking about this webcon unit because the Solex is really driving me crazy and I'm fed up with poking in the fog.

A Weber downdraft (or that throttle body) will fit directly on the factory 2-barrel manifold noting, I think, the throttle plates are 38mm on both throats. This means that a phenolic spacer of about 5mm will stop the throttle from clashing with the manifold opening. 

 

Alternately 5 minutes with a carbide burr will allow you to open up the opening to fit the throttle plates. The advantage is that it will also increase airflow which will be advantageous with the FI.

I LOVE this! No jetting, no float bowl crap, etc... plus paired with an inexpensive EFI ECU / Wideband 02 and your choice of injector size one could really tune this setup to make great power throughout the powerband.
