cd strombergs

What is the general consensus on these when used on a 260Z?  when considering A: Performance and B: reliability?

I Like de 'olden

Cheers for wasting my time.. now allow me to waste yours.

A choice missing would be C: Why? I'm sure if there was an advantage in their use there would be a whole thread dedicated to them. The tried and tested Hitatchi carb is the one to stick to. Might as well install a 186 Holden red engine to go with the Strombergs..

Well you can see how many replies you've got to this thread, wouldn't that be some sort of a hint?

 

I sold a set of triple strombergs for $350 that i bought for $100 sat in my garage for two years while i built two sets of triple Dellortos one of which was sold to somone overseas. Strombergs are for holdens in my opinion, if you want decent carbies for the l series spend some money as i can gaurantee that no one in this club (that i've been a part of for nearly 4 Years) has EVER bothered with them. That being said i'm sure they're easier to set up then some.

 

Pay your dues and earn some respect!

CD stromiies are a side draft like an SU, arent they

If the OP was refering to the either single barel or dual barel downdraft,like holdens have

Then the factory dual barel carb are so much better

But IF refering to using them on a side draft multi carb manifold

They should work,shouldnt they

early V12 Jags run these, jetting would be the same

Thanks to those who replied with sensible answers.  I was curious as I had a  pretty decent Z engine once that ran CDs and I was just wondering what other people thought.  They worked fine, but ran out of huff up top at around 215km.hr

Why did they run outta puff at 215Ks

Was the engine at max revs for the speed,was everything else up to goin faster

OR maybe you had a hyundai excel in front you couldnt get around

 

Diff gears,tyre size ect can make all the difference at top end

Had a fully worked 6 powered LJ torrie,that at just under 6,000 rpm was at 140Ks

It was set up for the 1/4 mile,but boy it got to 140 real fast

215km did you forget to change into top gear 7500 in fourth will be get you there (but the cds will be good )

CD Strombergs work in the same way as SU's. ie a moving piston activated by the manifold pressure to vary the venturi diameter.

 

So for the same venturi diameter (and suitable needles and jets) they'll have roughly the same performance characteristics as SU's.

 

Strombergs rely on rubber seals to get decent air-sealing to present the manifold vacuum behind the venturi piston however. Whereas SU's just have really close tolerance on the machining in the piston. Hence Strombergs will require more stuffing around with maintenance over time.

 

You'll probably have to do a lot of experimenting to find the best jet/needle settings for Strombergs in a Z, as there won't be much in the way of previous knowledge about.

 

Hope this helps!

well to start I have 2 of these , each has 4 carbs, two on each bank of 6 cylinders, 5.2 litre, you do the math
