Ah - and I'd like to apologise for the gramatical errors in my posting... been along day, and ground up two road-rocket spec cylinder heads. Brain and eyes are a little fuzzy! KC

still awake, i think they might have seen way too much reading and gave up, you know these southern hemsphere types have an attention span of now what was i saying.

every one is favorable to what type of carb they think is best but i have had no hassles with a side draught or a SU.
which may i add although you can look at it as a side draught it is also the closest thing you will get to fuel injection with its totoally variable needle and fueling.
you know what i mean.

Greetings Keith and Great to see that you have found the Austrlian Home of the Mini

Its actualy funny. We argue about Round nose's are better than Clubbies, and now we argue (or Banter) that Webbers/Dellortos are better than SU's.

I like my HIF44 as that is what I am use to, Kev is Use to his Dellorto's and GR likes his Webbers. If you are going for all out power may it does matter which one you use but most of us just wont bragin rites or it just for the road car.
Since fitting my HIF44 with a PCD manifold (from a Log) I have noticed a good improvment in porformace so its a matter of getting all good product's and Tuned by somebody that knows what they are doing on a Dyno

Hope you stay around and have a laught with us..cheers

Nice one Jai - also forgot to say - if you're doing it for the 'noise' factor... then there's no argument. Choose which suits the melody you want to hear. KC

Keith, I agree with you that big twin SUs are good but here people seem to think they are too hard to keep in tune. This comes from running old worn carbs and linkages, IMO.
I run twin HS4s on one car (1293) and a 45 Dellorto on the other (1360). Both work good, the choice of carbs fits with the use we put each one to.
Yes, the SUs are more economical too.

hey keith could you imagine having a side draught on my car, i think my ears would be bleeding by the time i got to the end of the road.

would you belive i still 13.5km to the litre in my car which is good for what is it is.

Yeah - there's this whole 'twin SUs go out fo tune' thing... absolute cobblers. Once set-up there is nothing to go out of tune. KC

mine did all the time.. POS.. yes i guess they were worn.. but fark it... I like my single now

hasn't this been a fun topic and so much information and some of it even true As i said very early its horses for courses and comes down to what you like and what you have. Many claims and counter claims about which is better, it doesn't matter as long as you are happy with what you have its all good, if its fuel consumptionn you are chasing don't look for power and if its power your chasing who gives a damn if you loose a couple of MPG, the facts are that the best race mini's all over the world use Weber/Dellorto and the reason is they work for street use I rally dont think anyone could tell the difference between a well set up pair of SU's or a weber except for the noise

Jai - You love anti-social and you know it.... Stick to the SU though - it's more 'Mini' than a Weber!

The main reason for twins going 'out of tune' when a little long in the tooth is that the linkage lever arm clamping screws have been done up frequently and excessively tight by gorilla-fisted previous owners/technicians. The screws/bolts stretch/bend and the lever arm distorts. Anybosy that intends fitting used twins should do a complete over-haul. Those linkage bits are not at all expensive.

And Feralspirit - you make agood point - but the pint here is often 'what gives best power' hence the debate. For noise, Webers get it. For pose maybe Webers and Dellortos (coz they're a bit different) get it. But my money is on twin SUs. They look right, give the required performance and don't involve butchering the bulkhead to get them to fit.

KC

Yes-Yes(thats two)Now check out other topic"Twins are Cool"
I rest my case

Welcome Keith....good to have an expert of your calibre on Ausmini....just have a look at worldtime.com before wondering if anyone is a wake!! Cheers, Mick

"Show me the Mini!"

KC, Kev, Feral et al..... (First of all, welcome KC - great to have another mind on board !!)

I'm not certain that this "Maximum power" is what mostof us should be achieving ....Something I've learded from the Turbo 998 Experiment has been that Maximum power is almost useless in all but the most outright fast part of the race-track.... where the turbo has been great for me, is "Fattening" the torque curve and making the power spread more usable ....

I've got a fairly peaky little engine, max power happens about 7000 RPM, but unlike a N/A engine whose power is at the same peak, I've got a very fat torque curve.... so the power is available on the street, to climb hills, upset ricers, etc ...

The point I'm trying to make is... a Car with 100Hp @8000 RPM, will most likely get killed bu one with 75@6000 through the majority of driving (Street etc) - Its able to USE its power, not just get to a point and then "hit it" ...

I've owned some really nasty N/A engines with HUGE power (400+HP) but it developed it so far up the rev range, it was almost usless, and i was left with a soggy, lumpy mess in the "normal" driving range ....

So to sum up, I'm an SU fan over the Weber/Delorto/Solex etc ....... they seem far more "Flexible" than an equivalent sized Side-Draft .........

/Rant off

hee hee,,,i remember quite a few years ago when i first clicked onto MiniMania site & blurted out how much i love my twin inch & 3/4 SUs on my 1415cc strokers & didn`t i get a bashing from all & sundries, my first ever stroker that i built when i was 15/16 years old had em & i`ve still got em, & they`re still sweet

i went on & on about how much testing that my dad had done for so many years & sorted all the sugar from the crap & ended up with a way better carb set up with twin inch & 3/4 SUs, i`ve never strayed from that being the best set up for both road & race till now,,,simply because Bimmer twin cam 16v with turbo & sequential engine managment system is now the new ruler but i spose you`re all gonna call it cheating ey???

ha ha,,,well,,,now the secret is out & not everyone is a happy camper

webers are nice, loud, raunchy & "look & sound" fast,,, twin Sus are sweet, neat & period but really do supply the goods """"""""""when set up well""""""""""

But, nobody can argue with late model technology tho, Far far superior with engine managment,,,ok ok,,,not many can afford it or would even really want it, so what tho,,,i can & do

but back to the question at hand, twin SUs are really the ducks nuts if purchased at the right price & set up by the right person the right way on a good manifold with the right donk, just that most pieces of sh!t twins sold at swap meets are just so crappy that nearly everything has to be done to em & some people are blind to that fact, they just think they got a bargain & expect that they`ll just be able to be bolted on & be better than the single carb they had, but quite often that`s not the case, good chunks of money & time would most likely be needed to be spent on the "Average" 2nd hand twin carb set up to be sweet

webers "can" be a little easier in the "Average": situation,However you can still be burnt with buyin 2nd hand weber/dells too

a crappy poorly set up weber/dell can be easilly beaten by a single inch & 1/2 SU on a good manifold,,,a crappy poorly set up SU or twin SUs can easilly be beaten by a wonderfully set up weber/dell on a good manifold

most of any big differences between weber/dells & twin SUs come down to how good the manifold is,,,simple as that, """if all else is perfect""" & size for size, then the best manifold will win. FACT!!!!!!!!!!

Keith,,,good to see you here & a big welcome to the Aus mini board, & also have a dam good chrissy & wickedly wonderfull new year, stay safe & please drop in more often & spark up some more lively converstions with all these mini nuters

I`ll have a few wild turks for you old fella

Suck it & see
