Cheers Tumbles...

Tumbles,

In my opinion unless you know how to tune SU's don't buy them. Chase up a set of CD Strombergs off an XU1. They hold tune and are very streetable, and will make decent street power. SU's are problematic and to be honest, not worth the effort. Maybe a bigger single carb will suit you better? Maybe a set of Webers or Dellorto's? If you're gunna f*&k around tuning carbies every weekend you may as well tune good ones.....

What engine work is done, and where and how do you drive it? Drags, street, up the shops, around small African countries full of nude black women?

Cheers,

Craig.

Prices seem to vary state to state with second hand set ups.  They are usually around the $500 mark in QLD second hand.  Generally less down south where there tends to be a surplus of that sort of stuff.

I think manifolds cost between $100 and $200 new and vary in their design for firewall clearance etc

I paid $350 a few months back, for a set of 1 and 3/4 inch SUs that had been rekitted with with new fuel lines and splitter and the filters weren't in bad nick.  I consider that very cheap - but i got them in a country area where the seller would have had difficulty selling them.

I bought mine for a daily driver - but haven't put them on yet...still deciding as most people with more experience than myself tend to think they are a lot of trouble.

I've been looking for a set of triple strommies for quite a while and have had no luck at all.

From memory the CD Strombergs and SU's have the same mounting holes so you can buy a brand new SU type manifold and chase up some CD150/175's off some pommy crap - Landrovers, Jags, and Rovers used them. I would think you might even be able to get them new, or at the very least fully reconditioned.

Take it from someone who has had red motor experience with SU's, Holleys, CD's, and Webers. For street use, choose the CD Strombergs any day. Good fuel distribution, good power, and best of all, they hold their tune.

The attraction of an ex-XU1 setup is the excellent linkages.

Good Luck,

Craig.

Thanks for the reply, to answer craig, was thinking about putting them on a worked grey, mainly used as a sunday streeter and I'm not cruisin for black chicks as the missus would probably get stroppy  I have a twin strommy manifold and a tripple strommy manifold in the pipeline, would I be better off with those? I was thinking that they would have a lot of fuel drop out at the 90 deg turn at bottem of carb which is why I was thinking about the su's.
Dave did you want the manifold for a grey or red? You could try putting and add in the parts wanted section....

Tumbles,

Sorry I was thinking red motor............ Me thinks me drinks way too much VB these days  

The SU's will OK but you will need to be prepared to put the work in to maintain their tune. You will need a carby balancer and a vacuum gauge, a a bit of patience until you get a handle on it.

The upright Strombergs maintain their tune well, but still require accurate jetting and set up with the carby balancer. It is a simple tool that measures the airflow through each carbies venturi. You can also use a length of hose and a keen ear.

Its absolutely critical with multiple carbs that you get even airflow at all throttle positions - otherwise you will have some lean/some rich cylinders. The rich ones just waste fuel, the lean ones have a tendency to melt pistons.

Good Luck with it all. There ain't no better sound than a hot grey/red with multiple carbs and no air cleaners. WOOOHOOOOOO!!!

Cheers,

Craig.

P.S: you don't need multiple carbs to catch the black women, they tend to be slow runners because they don't eat very much.

[Tumbles]

I wonder how much money in shopping one would save me, no multible carbs, doesn't eat much, I could probably catch one in a Ford!!!

Tumbles, I know where you can get hold of a twin SU manifold and some SU's that would be suitable for parts.  The beauty is the twin manifold, only ever seen one other, came up on ebay about six months ago.  Twins mean one less to tune and they fit in the engie bay without causing grief with the battery box etc.

I think I have a picture of one somewhere I could email you if you wnt a look.

gday,reading this post with interest,i sold a pair of twin SU.s on manifold for a red motor on ebay about 6 months ago,they were the only twins id seen in 25 years ,i had never seen any for a grey though,but in last 3 months ive seen 2 others one for a grey and one for a red,amazing whats coming out of the back sheds nowadays.be patient and you never know what will turn up., as has been said in a couple of other posts, tripples are hard to keep tuned but you can buy the plastic air ballance tuners for under $30 which makes the job easier to do.also with FE-FC's most tripple manifolds have a straight out manifold that will mean big modifications to your firewall,so if you do decide to go tripple find a manifold that has them turned towards front of car to clear the end carb from touching firewall.

[Tumbles]

Thanks for the warning Nicko, didn't think that the tripple's would foul the fire wall, had a set of webers in LH torana with 5" air filters and they cleared! any one got any photo's of a set installed and in the eng bay?Mike if you could send me a photo that would be great, send to virus@ausfish.com.au
 Has anyone tried to fit motor bike carbs to a su manifold??
Does the tripple stommy set up foul the firewall?

[nicko]

i was refering to SU's .strombergs are fine as they are downdraft so sit directly above manifold .

[Tumbles]

point taken, but so far every one is telling me it's a pain in the ass, might look at twin su's.  Thanks for your input everyone..
