He would also find it amusing to use the flames to awake people in the morn at shows :D

You also wouldn't need to go to the burger van for lunch...................

I remember waking up at Weston wheels to see a civic dragging someone aorund in their sleeping bag with a tow rope!

Was rather amusing especially with the 2ft flames licking out the back :D :eek: :devil:
 
I'm sure I read just recently in the "lets talk fiat" section about being able to fit the inlet manifold from a A series engine or something on the fire engine, if this is the case then you could get an aftermarket manifold for twin SU's carbs, I had this set up on my original MG Metro and it has a 1275cc engine which is comparable in size to the 1242cc.

On looking at this it doesn't look poss, but I'm sure a nice manifold could be made for such an application cos how nice do these look!

or twin 1 3/4 SU's Mmmmmm http://www.minisport.com/classic-mi...-kits/twin-1-3-4-su-carburettors-product.html
 
would be better to get the twin carb manifold and fit twin throttlebodies instead. you would need to buy an aftermarket ecu though, Ask TBsei, I'm sure he knows all about setting them up.

That would be alot easy to control, adjust and will be a lot more economical than carbs.

On the old Arden 8-port Minis, they used Amal carbs, one for each port. They'd look pretty classy too.

But were a right pain to set up for road use :(

1.5" SUs are the ticket! :)

Maybe he'd like the challenge, LOL!

SU carbs are great, especially the later HIF version. I'd be well gobsmacked if I saw some under a cinq bonnet.
I doubt they would fit as they barely get under the bonnet of a panda..

Its a step backward imo especially seeing as injection per cylinder is already available for relatively sweet F A if you look at the cost of a 75 MPI head.. Fitting and setting up would cost just as much as getting DTA with the 75 head..

The Panda inlet could be used to house a single Carb but even that's too girly for me!

But.... if I was going to do it I would get the twin alfa 33 carbs (about £50 a set) and get them rejetted... twin 32mm throats... mmmm I do like the sound of that.....

Another problem I can think of is, what about the clocks? Would you not loose a lot of the information? At least the speedo is using a direct cable and not via the ecu! lol
 
Hi
How about twin weber ida 36mm`s from an alfa?
Pandamonium runs this setup,
Also i think the catalyser will still work because exhaust fumes are exhaust fumes however they are made the only thing that would need removing is the lambda sensor (wouldn`t that be a shame?:D )and that could be replaced with a bolt of the same length and thread,
Cheers

P.s how come about a year ago when i mentioned converting to twin carbs i got shot down in flames but when mase mentions it everyone thinks it`s a great idea?????:D :D :D
 
the cat would work, but carbs are setup to overfuel slightly - fuel destroys cats. so the cat would work for a bit, then block up. already been explained in this thread though i think
 
Did someone mention twin carbs ;)

I have a tuned X1/9 and twin 40's are if anything slightly too big for that and that's with 32mm chokes!

form reading through the the power tuning weber dcoe book, i discovered that some british leyland cars came with a single twin choke carb, one choke for two cylinders, using what is called a siamese manifold.

The twin Webers from the Pandamonium engine were to big at 36mm. Maximum should have been around 32mm. Otherwise the inlet manifold was custom made and would not fit the Cinquecento.

There are cars that run on cats with carbs, but the catalysis is a bit more complex and fragile in the wanted way than you might think. For roaduse I would not advise anybody with a post 1992 car to convert to carbs. Most of the reasons have been mentioned previously.

And I stand corrected re the mini. ;)

Maybe, maybe not.....

Donkeys ago I worked on a 2.0 Austin Montego which had a stepper motor equipped carb to alter the mixture, so it's quite possible they used the same bodgy technology on the mini.

It's the same principal as using injection - a feedback control system.

But if the engine is a pre' 1990 ;) :D

Also I though if your car passes the emmisions a CAT is not needed?

Emissions rules apply to the car as-built. You have to satisfy the Cento emissions targets even if you manage fit a 427 Hemi.

..at which point, I would quite likely propose.

A cat is legally required on all post-1992 cars, especially if fitted as standard build.

The 2 litre wasn't an A series based engine - the only Montego with a similar engine to the mini was the 1300 Montego...............

The 998 A series when fitted to the likes of the Mini 30 used a single 1.5" SU carb. I'm 99% sure a cat was an option. Injection didn't appear on minis until 1992 ish (IIRC) with the advent of the mark 6 mini.

Sorry Pete, but it is not correct that the cat is a legal requirement. The legal requirement is not to exceed the post 1992 emission levels (after various debates we looked it up in our MOT guide lines). Admittedly it is not easy to do this without cats. Still it can be done.
