5 bike carbs?

Big hassle, big money. Maybe more power.., but at the expense of your sanity. You'll be forever tuning it and fiddling under the bonnet. I'm sure it would get right on your tits.
Bit of head work, as mentioned above would be far more economical.

You realy need to spend some time in a book and read up on this subject.
How often do single venturi side mount carbs come up for sale??? and then you need 5
What manifold are you going to use?
If you find 5 carbs that will do the job where are you going to get jets and needles?
I would be amazed at any gains by just swaping efi for carbs, those situations that are reported are always with the cavat that some engine work was also done at the same time .

ANY THINGING IN 5'S WILL BE EXPENSIVE OR REQUIRE WORK SHOP TIME.
Tb's are a lot simpler to make as you make how ever many you need, and you can set out the manifold direct. But you need a stand alone ECU.

Get a 100 turbo and strip it for the engine.

This is for another project along side the 2.5 ??? as that is tuned for K jet.

i was thinking about it for the 2.5L . it was only an idea...

i had 'thought' a standalone ECU and TB setup would costly??

Bike Carbs are very reliable, much more so then DCOE Weber 40's or 45's that go out of balance every 3000 miles!!!! Especially if you get some of the more modern set up like from an R1 or GSXR750/1000 etc as these use electronic fuel pumps aswell! The only prob I can see is getting 5 of the things as they usually come in banks of 4!!!

Good power gains can be had from them aswell, once properly set-up etc! I know a guy who as a set of R1 carbs on his 16V 'rocco. Only other mod is a polished and ported head and that pushing the 170bhp mark!!! Pretty good i'd say, plus it sounds awesome on full chat!

You can pick a set of R1 carbs complete with pump etc for £100 or so on fleabay! Company you really need to talk to are Bogg Brothers! They are the daddies, they will build you a custom manifold and can even redrill and set up your carbs for your particular car! Looking at your you tube links in the 1st post Bogg Brothers actually sorted the manifold etc on that audi so would deffo be worth talking to them!

You will need to keep the ignition side of fuel injection system etc but I reckon you could be up and running on bike carbs for £500 to £1000 including the carbs, manifolds and RR set up!

Plus who else has done this in the UK??? Bet they're ain't many, modding is about doing stuff that ain't been done before.......I think it would be cool!

The Noise will be worth it

Haha, carbs

We live in 21st century, guys

Carbs - it's a simple and complicete solution in the same time. Simple - because there isn't so many bolts

In the same time - what else u can do with car like this, apart from sound and a little power increase, because it doesn't consumes fuel anymore, it guzzles. Example with corrado & carbs = 170 bhp isn't cool - i know ppl with mk2 golf, 2.0 DOHC engine, vems and some minor modifications, and 175 bhp. I'm afraid, that car with vems can be used dayly, unlike car with some primitive carbs. Well, i also know one another example - B2 A90q, ppl installed in this car 7A engine, installing on it pure k-jetronic from KV, only nozzles were different. Fuel consumption was 10l/100 km on road, 20l in city

Price for torque

As owner said - he was able to drive in 4th gear on 1k rpm without downshifting

rado-steve · 12-08-08, 04:44 PM

going from a 136bhp 16V motor to 170bhp with the addition of carbs and a head job (Head prob gives 10-15bhp increase) I think is pretty decent add some cams in the mix and you'll be knocking on the door of 180bhp!!!

Anything that increases engine performance is going to knock fuel economy, Bike carbs are a lot more fuel efficent then a set of twin 40's webbers etc!

msh · 12-08-08, 04:50 PM

And what u will do, if u want 200, and not 180?

In that case u will trow out your "very cool" carbs to install EFI & turbo

rado-steve · 12-08-08, 05:51 PM

If I wanted 200 bhp I'd throw away the old motor and fit a 1.8T
