DCOE on PRV6
 

i have been thinking of doing this for years

now overseas you could get a volvo with an SU hanging off the PRV6 engine so this then begs the question

how hard would it be to put a single DCOE on a PRV ?

in doing this you would gain more access to one side of the engine but then limit access to the other side

not that it is a big worry but still

anyway the induction noise alone would make it worthwhile and i think a single 40mm DCOE would do the job nicely

the next thing would be modifying the manifold to suit (not so easy) or grab an SU manifold from overseas and modify that instead (maybe easier although may cost more)

the other thing i always wanted to do was to make a cross over manifold to have twin DCOE's on a V6 but that wouldn't be a practicle everyday car but would be nice for something that you didn't use everyday

Didn't the Talbot Tangora have 2 triple Webers. How about getting this set up fitted, It's sure to make one hell of an induction noise and you could probably get the parts from France (at a cost of course).
Be a pig of a thing to set up properly and the fuel economy wouldn't be good, but it's 'off the shelf'.
The Talbot Tangora was an 'everyday car' so this set-up must of had something going for it.

Crossover SUs would be nice...

And the DCOE, that could actually be mounted fore and aft instead of just across to one side. It's been done before.

yeah i have seen that set up and one of the members here has that setup on his 504V6 but that's been done :D

i was after something different and seeing as DCOE's are common they are much cheaper than the triple throat webers

Ren,
The Talbot Tagora was indeed an 'everyday car' and as such would have used a simple carb set up on both the 4 cyl and V6 examples.

The two triple throat Weber example mentioned must have been highly modded by some French Pugrambo! :wink2:

On the Tagora. A couple of years back Mitsubishi Aus in their wisdom used the name Tagora on one of its models.[Magna?]. In our Club magazine, The Lion, I commented on this, in particular Mitsubishi's poor knowledge of the old parent company Chrysler's history, in that the Tagora was generally thought of as a "lemon". I haven't seen or heard of the Mitsubishi Tagora lately? :clown:

I was going to put twin crossover SUs in mine, and if I still had it that is exactly what I would do, either that or throtle bodies and Megasquirt.

single SU is easy as volvos had that setup but i much prefer a weber over the SU

the weber setup would be nice i reckon

even single would be good but i would start with a volvo SU manifold and go from there

twin DCOE's on a V6 would be even better and probably easier to do in a cross over format but of course any DCOE is going to cover the plugs and make it a little harder to work on but they are easy enough to remove when you need to change plugs out

the tagora SX came standard with 2 triple throat webers :D

Tagora SX, Moteur V6 PRV (à 90°), 2644cm3, poussé à 165cv DIN (144cv dans la 604TI), 2 carburateurs triple corps, boîte 5 vitesses ou automatique, disques ventillés à l'avant et pleins à l'arrière, air conditionné et intérieur cuir en options.

thanks but no thanks

i want weber DCOE carbs :D

i would if need be grab a renault 30 injection manifold and cut it down

but then if twin webers were used you would only need part of the standard solex manifold and make up the rest from there

i don't like and will not use SU carbs and yes i have played with them and have been able to set them up but i just don't like them as much as i like webers

italian engineering is always better than pommy stuff :D

I don't think that's your reason, however...

Carby's For Prv V6
 

You know, in my minds eye see Pugrambos' 604 with three Weber 32 IDA s
on nice aluminium cast manifold. Since he has given me so much curry about my 404 I can also see a large air scoop on the bonnet .

On a more serious note IDA s would be absolutely ideal and just imagine how it would look.


Pity you can't get them anymore

there is a 404 in Vic that has a PRV engine and triple dual throats on it

sounds nice too :D

All 404s are nice...

404s
 

Provided you don't mess with the already beautiful appearance too much.

you mean the Austin Freeway appearance :roflmao:

no thanks, the only good thing about that 404 i mentioned was the exhaust note for me i'm afraid

then again any odd fire V6 sounds nice with a good exhaust

i wonder why all volvo V6's sounded like hoovers and yet 604's always had a nice note from new

What about 1 DCOE on each side of a volvo twin plenum manifold. Just machine the the sides of the manifod flat, drill some holes and blank off the throttle body inlet and your nearly there. Carbies would sit over the rocker cover so no access issues for plugs.

Jarrod

not a bad idea at all

the carbs would still be sitting over the plugs though and seeing as i only have one twin plenum setup here i'd rather not do anything to it but when i come across a few more it may be worth playing with

setting up the throttle linkages will be the next work of art

Those things are easy come by...

And as I said before, you can mount it to the front or the rear, as DCOEs will work like that.

room is too limited that way though that's why i went past you mentioning that before

to the side as per normal fitment is about the only way and still have enough room to mount them

improved injectors
 

Hi FarmerDave
What are these improved injectors that make all the difference? :confused:
I would love to know.

i still have plans to modify the twin plenum i have here to mount the injectors in the legs of the inlet manifold and hopefully try and have a megasquirt setup instead of the K-jet

this is one reason why i don't want to use the one i have for the DCOE experiment

i just want to have a play to see what the outcome is with the DCOE/'s as i will eventually have everything i need to finally stick the injection on the car and do away with the carb

the only other thing with the twin plenum is it tends to sit over one side more than the other and makes getting to the plugs much harder but hopefully i might modify that as well to make it easier

i'll play around with it all on a dummy engine i have here with just the block with the heads bolted on

Aren't they CDMA phone numbers?

Want to be careful who you call...

Oh yeah, how come that space ahead of the manifold is too limited?

i'll show you next time you are here

Cool...

DCOE on PRV..
 

Pugrambo, I am at your mercy with your Tagora V6 with "triple corps".
After reading the above I went through my collection of English Motor Show brochures looking for the Peugeot/Talbot models for '82. No luck but I'm sure your description would have etched into my brain back then.

I wonder how they achieved the under bonnet clearance for 2 triple throat, very upright Webers? This set up in its most common application, flat 6 Porsche is understandable not having underbonnet problems.
Of course such "blood and thunder" cars as V6 Ferraris and other competition vehicles have used them but have had to accomodate them with extreme bonnet bulges. Not very practical for an everyday car, not even a 604 with optional leather interior. :wink2:

there is a certain 504 in Vic that has these webers on the V6 and they fit under his bonnet

i do recall seeing a pic somewhere of the tagora SX with the triple throat webers on it and the air cleaner that sat over the top of them

i'll see if i can find it again and post in up but mind you when the air cleaner is in place on one of these there isn't a lot you can see in there :D

here you go

check the pics out on this page

very interesting and very nice

i'd love to know what the fuel consumption figures would be

Note my avatar, my 504 V6 2850 oddfire has the Talbot Tagora triple throat 40mm IDA Webers and Manifold, these were also the same as some earlier Renault Alpine V6s. They sound great but what you notice most is the throttle response. Since each cylinder has its own throat the vacuum signals are optimal and any change in throttle position is instantly responded to. These are hard to find and expensive if you do find them. They fit under the bonnet OK.

After initial setup with a dyno the carbs have been faultless although they had done very little work before I got them. Fuel consumtion is up to the driver, you can make them guzzle but with sensible driving they are quite good, for me they always guzzle. They are quiet with gentle driving but the moment you want to accelerate they are noisy, but a good noise.



See the photo without foam filters.

'Rambo,
Thanks for the pictures, they don't sit as high as I'd imagined. If I had a 604 equipped with this lot it would have the bonnet up all the time to impress the mob! :cool:

I wonder if they had the triple Webers tailor made or was it a fluke that they matched the V6 ports? :adrink:

well i suppose we are lucky with the PRV that the ports are equally spaced unlike the V6 in the capri

from what i can remember the inlet manifold for one of them had the front inlet ports a long distance form the rear ports

just goes to show how some nice italian webers are perfect for pugs :D

They were probably made for the Porsche flat 6 or the Dino Ferrari V6...

Oddfire,
Thanks also for your pictures, a very neat and unfussy set-up.
What's this? A BRASS bodied coolant filter in the top hose!! Don't let 'Rambo see that. :eek:

Looks like one of Christine's plastic ones painted with gold paint to me...

In respect of the brass fitting in the top hose its the only way to fill the cooling system, if you look at the radiator you will see it has no cap anywhere. I think the radiator was for a version of a 505 Diesel that did not come to Aus.

The IDA carb throats are about 10mm or so closer together than the head ports the very simple factory manifolds fix this up of course. IDAs were common on Porsche flat sixes however Ferari Dino's had three twin throat synchronous 40mm DCNF Webers. These straddled the engine as per my mates excellent V6 404 see photos with both IDAs and DCNFs.

Why doesn't Rambo like brass stuff?

electrolisis between the brass and alloy via the coolant bieng one of the causes to corrosion in the blocks

You should get one of Christine's filters then... heavy black plastic, filter is removable for cleaning. Brand name is Tefba... at good stores everywhere.

Must have been another V6 Ferrari engine, prior to the Dino coupe... I recall reading at the time that there were delays with Weber's development because they were working on such a thing for Enzo. Or maybe my memory is failing me and the development work was for Porsche?

Anyway, it was a headache at the time and was so noted in some magazine somewhere...

any ferrari i have seen has had the dual throat webers sitting on top

i have only ever seen the tripple thoat webers on top of the tagora and porsche from the factory

i have seen another brand of tripple throat carb ontop of the flat six corvair engine though but they weren't webers that i do know and there was actually a pair of these on Ebay the other day as well as a few pairs of the webers and overhaul kits for them

Yeah, like I said, my memory might be playing tricks...

They might have done them specially for Porsche. This was in the sixties, of course.

There is also a Solex 3 throat down draught that looks almost the same as a Weber IDA. I got another mate that has some of those in captivity as well.

The filter thing sounds interesting I will look into that.
