Hey guys.

I've had a look around to see if anyone has any photos but I can't find anything.

I was wondering if it was possible to fit a centre speedo with the webber box? I saw a thread on this before but it never got answered

I really wanted webbers on my car but I don't think I'm prepared to loose my centre speedo

[CobraV8]

I have a webber on my car with a stumpy manifold. This means that the carb ends before the firewall, no need to relocate speedo.

[HARBER07]

It can be done with a swan-neck manifold (currently i have one for sale), but at a loss of performance. I used a 40DCOE on a swan-neck manifold though on a 998 and lower down torque was definitely improved!

I have fitted a weber with a 5 inch manifold and 10mm trumpets without mods to bulkhead. or you can try split webers as they use a shorter manifold. That is what they used back in the day!

[MK1]

Don't know alot about the different typres to be honest. What can I expect in performance from "split webbers".

This sort of thing?

And that will fit without any webber boxing or bulkhead modifications? Its going in a Mk1 and I don't want to play with the shell if I don't have to.

Split Webers are for real high powered minis, basicly the advantages of using them over a single weber is that the path into the inlet ports are straight, what is yours going to be used for and what engine is it? You will still need to have a weber box for them to, probley even a bigger box! they arent cheap either.

As said above you can fit a weber without bulkhead mods, ie swan neck manifold and short rampipes... but i personally dont see the point of fitting a weber and then using a swaneck manifold...defeats the object of a weber carb.

Any weber is really only for high power minis but lots of people fit them to lesser mini`s! As i stated i have used a 5inch oselli manifold and not used a bulkhead box before, I`ll add some pics of this later.

IF you could buy a pair of 40`s cheap enough it would be better than a single due to the straight flow, Yes it can be expensive BUT depends what you can do yourself? Inlets are about £110 from minispares which is no more expensive than a normal weber inlet manifold. The linkage can be home built as per David Vizard for not much money (approx £40), You do not need a bulkhead box as the inlets are only 3 1/2 inches long. I have done this so i`ll add some pics later. But it depends on your spec in the end.

If you look at some old rally cooper `s` they do not use a bulkhead box as they where not allowed to modify the bulkhead in anyway.

MK1 you should see a gain using splits rather than a single BUT it depends on your spec of engine if you would actually notice it! Looks awesome though!!! Yes that was the link to split webers

Any pics ? i'm intrested to see how you have fitted a 5'' manifold and have kept the bulkhead untouched, what size rampipes are you using then?

[mini_kel]

Trumpets are only 10mm i`ll try and add a pic later. If not you will have to wait till the engine is back in the car! hopefully this weekend!!

I`ll get a pic of the split 45`s aswell

Dont do splits, sounds odd but they give less power than a single believe it or not.

I have a 5" manifold and 60mm ram pipes. I have extended the binnacle into the car by 2"

Not - If setup properly on a race motor split webers do produce more power, the idea is a less turbulant run into the ports. I dont see why you say they produce less power?

[Paul Wiginton]

I say it because I did it, Swiftune did it and Pete Baldwin did it, all on seperate race motors.
Mine is a 1380 full race 310 cam full works Swifty head etc etc and set up by Swiftune on their dyno bench initially then goes to Baldwin every year for a check on the rollers
I know of others that have lost power trying splits

Thanks for the advice guys.

Well I already have a normal Cooper MPI so this car is going to be a toy/road legal track day/fast road car so the engine (assuming its possible - I have alot of advice to ask on the matter but I'll start here) was going to be an MED 1430 so yes a highly powered engine. Shame its going to cost the value of my other Mini lol. But as I say it is going to be a performance car but I don't mind losing a few bhp for keeping my interior standard - its going to be fast enough already!

Guys some stunning cars in here and Paul - your car looks stunning, always have had a soft spot for your avatar photo! Paul can I ask what you've done in term of suspension and brakes on your car. From your avatar it looks like a Mk1/2 so I take it you lost your hydrolastic and swapped it to a later setup Mini suspension with shocks?

Cheers for the help guys. Trying my best to learn whats possible here!

p.s. at soe point someone will explain to me that a 1430 MED is insane and I should get a 1380 or something....

Its a 1960 mk1. It was dry suspension to start with, but I have since made my own rear trailing arms from T45 CDS, front spaceframe instead of subframe and tubular front top and bottom front wishbones all, again, from T45 CDS. It runs on Protech coilovers
There are pics in here

Paul just seen the thread actually after reading your profile. That car is beautiful. Fantastic work well done. That set-up is something I would never be able to do I'd have to get someone to do that when I'm getting the shell restored/painted.

Is it a road legal car?
