dual carb kits.

ZionVier · Post by **ZionVier** » Mon Jul 09, 2001 2:15 am

I am going to be purchasing a set of dual carbs for my stock '70 bug 1600 engine as a way to gain a little extra power boost. I'm on a college students budget (basically no budget) and I don't really have the money to spend on a set of dual weber 44s or something of that caliber.

After looking through many catalogs and online stores the prices for a set of dual carbs have a fairly broad range. I realize that I will get what I pay for and that a cheaper set will not perform like a set of webers, but what I am curious is just how much quality would I be using if I went with a less expensive non-weber kit?

also, another question.... Would going to a 40mm or 44mm dual carb setup be a dramatic increase over going with a 34 ICT dual carb setup? Considering it is a stock engine (I am guessing it is single port) 1600cc. Is the extra money I would spend be worth it on such an engine or would the larger size not give as much of a performance boost because of the single port?

34 ICT carbs are good, just not real big power makers..

A set of 44's are way too big for your 1600 engine...

Save your money for a little longer and invest in some dual DELLS, or Weber IDF carbs. Check out EBAY for them in used condition, I like the older webers better than the new ones anyway..

Do yourself a big favor, and don't let the KADRON carbs grow on you, spend the $ for some Webers or DELLS, and then you can resell them quickly, and maybe for more than you paid for them.

A set of two barrel carbs wouldn't do much for you on a single port engine. I would say the first thing you should do is convert to dual port heads.

the guy has not said his heads are single port and in >1970 1500 = single port
1970>1600 = twin port
i have a 1641cc t1 whith twin 40 kadrons on i paid £70 for them and when i sell them i expect to get £100
but having said ths twin 40 delortos of a alpha sud & a set of manifolds work out at £250 max so keep tour eyes peeled for those swap meet bargains

In the US - 1970 model year = 1600 Single Port, 1971 model year = 1600 Dual Port.

I have a 1970 ghia and it came with a 1600 with single port heads and I live in the US. If he can spare the extra just get a set of 40mm webers It will work and give you lots of extra power than a set of 34ict's. 44 are to big unless you got the rest of your engine tweeked. The only thing bad about using a set of 40s on a stock 1600 is that they will use more gas and need to be jeted right after you get them bolted on. Check to see if you got single or dual port heads if you got single port heads pay the extra to have them changed to dual its one of the cheepest ways to gain extra power on a stock engine.

I have several customers running dual 44s on stock 1600s, you simply have to jet them down to 32 vents (and jet changes) to do it, and you have the advantage of having carbs you can use if/when you build a bigger engine.

dual 40 IDFs are very close to perfect out of the box, with no changes needed. ICTs are way off. Also, we offer a jet exchange program IF you buy the carbs from us, nobody else offers this.

Its true that 44 will work on a 1600. I have seen as big as 48s on a 1600. but he said he didnt have much money and why should he pay for more carb than he needs. If he builds a biger engine latter he still can go as high as a 1904 or a 1915cc with dual 40mm's.
Not all companys sell there carbs with the same jet sizes in them and if he was to get a set used from someone like on e-bay as someone else said early. Who knows what it has in it. buying from a place that has a jet exchange program is the way to go I wish all places that you get carbs from was that way.

low on cash, get some used 40s for around $350. RUN (dont' walk) away from Kadrons.

I guess I have to disagree with you guys on this one. A pair of 2 barrel carbs is a total waste of money on a single port engine.
Either convert to dual port or run a pair of single barrel carbs, assuming the exhaust system is ready to handle the increased flow...

If it's a single port, it will run worse with IDF's than with Kadrons. The benefit of having a throat for each cylinder is lost, and each cylinder will be pulling through two throats instead of one. This will amount to being grossly overcarbureted. If the heads are dual port (in which case it is not a truely stock 1970 engine), IDF's should work fine. As for Kadrons, I have run them with great success and recommend them on stock or mild engines. They are easy to tune, get the same or better fuel economy as stock, and provide a noticable boost in performance.

I totally agree with John....I refuse to even service/ tune kadrons anymore, the new ones are getting worse and worse..

I have NEVER seen a single port manifold for an idf (duals) I have ran a single (centermount)48 IDA on a 2110cc singleport with big valves, and port work. It was a dynoed 140HP beast!! Don't be fooled by a single port, we even have our "single flow" heads that will feed any size single port engine..

who sells a dual IDF kit for single ports? I want to see this one.

I would love to see that too, John.... I thouight about it one time, but it totally defeats the purpose.
