views on twin carbs

[Scottish_Gaz]

am i right in saying that twin carbs can be fitted to mk1 vts?

if so whats advantages?

also do you need a standalone ecu? as ive been told you dont

[Ryan]

i personally feel carbs are a big backwards step in tuning, id spend the extra £££ for consistent good running and TBs

[Coonper]

Personally i think twin carbs are a good way of getting more power cheaply. And carbs can be machted to any other mods easily, rather than spending £400 on a remap.

And you dont need an ECU at all as the fueling and air intake is all mechanical.:y:

Nice and simple, none of this electrical bollocks! You can actually see a carb moving unlike an ecu!:cool:

Not to mention the sound they make...:fcuk:

[Ryan]

yes the problem with them not having the fueling and air being run by an ecu is they are not consistant in all weather conditions like an ecu is.

[Scottish_Gaz]

what about performance? and how they make it sound?

[Berg]

they sound awesome :y:

and on brothers escort they made a massive difference in performance

[Sean]

as Ryan says really. They sound similar to throttle bodies, best bet is to have a look on youtube for twin carb cars and vts's/106 gti's on throttle bodies.

whats needed to fit them?

also what kind? as seen 40's, 45's, webbewr, not sure what difference?

if i bought a set, what else would be needed to fit them?

Major problems come mot time, cant see you ever passing an emissions test

If your talking a set of DCOEs they would be hard to fit them. They don’t even work that well by today’s standards. Have a look at bike carbs they fit at least but MOT is still not fun.

r1 carbs? mot not problem as my dads a mot'er and he does mine so im sure he'll get it passed

so back to the subject please, what do i need to fit also to make them work??

[Coonper]

I have a set of dellorto 40's that would work a treat on that engine! You'd need to get em set up obviously, but expect to see a 10-15bhp gain;)

They need some air idle jets, but you can have em £80. Which, believe me, is cheap!

And the noise they make is unmistakable!

They would be a bit on the big side but you could get them to work. You are more looking at a 600cc superbike. Give Bog Brothers a call as they have been doing this for many years. Though saying all this you really should look at EFI as it does not really cost much more these days and works a hell of a lot better.

You need some sort of ignition system, as the ecu does that as well as fueling!

No Distributer on a Saxo!!!

Thats a good point mate, but you could put a coil and dizzy on it without too much hassle.

Or you could even keep the ecu so it gives you a spark but does nothing else.

Dizzy is a little tricky as there is no stock drive for one, but it could be done. As said for cheap DIY people just add a TPS to the carbs and run the ignition from the stock ECU. It sort of works but is a really poor way of doing it as mapping it is very tricky. But the best way would be using a stand alone engine management system.

williams makes the inlet manifold for them ;) has one in his house, i would do it if seen a gain from it and didnt have to get a standalone or anything.

im starting to get dazzled now
