Webers Or Dellorto & Which Type?

[Vz_ace 0]

so, i have been dreaming about this amazing sound conversion for a long time now;), but before i decite to make the final step, i've got few important questions about that. i'd appreciate any yours useful guidelines and experiences. I'm questioning in the first place for a 1.9 gti 8v; and for a 1,9 16v -Mi16 in the second.

 

1) What would you prefer for each type of engine? Webbers or Dellorto?

 

2) There are many types of Webbers DCOE's on the market, with different Numbers stamped on them (18,19...152...). I suppose,that those numbers do matter. Which type is the best for 8v, and which type and 16v?

 

3) What do affect progression holes? Why are they so important exactely?

 

 

So, i just want to get to the right type selecton of the carbs, for 8v and in the other case-for the 16v Mi.

 

thanks for the answers.,

Vlado

one phrase, "Throttle bodies"

 

 

size depends on capacity and engine tune, tract length etc.

Ok, I'm not really talking from any experience here, so take this with a large pinch of salt, but from my youth I didn't think there was really any real-world difference between Dellortos or Webbers, I always thought one was a derivative/copy of t'other (not sure who got there first, though). We had a Lotus 7 that ran a 2.1 Ford OHC on Dellortos which I think were alleged to flow a smidgen more than the equivalent Webbers, but in reality you're going to put the appropriate choke sizes and jets in for the engine you've got. Out 2.1 ran 48mm chokes and they were too big; fluffy down low. I suspect a 1900 (either 8v or 16v) would not want anything bigger than 45's but no idea on what choke size you'd want to run.

 

I'd pick whichever I could find at the right price and in the right condition, but not worry too much about the make.

 

But please, someone with more experience come along and tell me I'm wrong ;-)

thanks,brumster, i appreciate your post;). I must admit, that i expected more answers like yours here..

 

Would be the conversation a difficult task? Is it ok to keep the std. fuel poump and low-pressure regulator?

Tb's may be 3x the price bit you get 3x the driveability. I would consider saving the extra cash plus with running aftermarket management you have the option of making more changes later on, just needing a remap.

i definitely agree with you,but that is not the point of this thema .

 

What is an average consumption with carbs if the economy of my std. 1.9 8v is around 9l/100km? (mixed),for example?

[trogboy 17]

If you are going to go the carb route and haven't bought anything yet you should consider where you are going to get them tuned. This may sway your judgement as typically Weber are more common so most carb specialists have a greater range of jets and emulsion tubes for weber side drafts than the equivilent Dellorto's. Not the end of the world but it would quickly become expensive if you are having to buy these in order to try different settings.
