Title: Ida Vs Idf
Post by: steveo_32 on August 24, 2005, 02:31:08 PM: What do you all like for a street/track driven carb, Lots of different opions out there, I would like to hear what users on airspeed think!

44IDF VS 44IDA or 48IDF VS 48IDA? :D

Post by: James Buchan on August 25, 2005, 11:47:27 AM: I vote IDA as well here's why:

They are the BIG BOYS when it comes to carbs and they sound awsome under load - nothing like th bark of an IDA.

Mine have some mods done, 3rd progression, enlarged float bowl etc... and I find them quite easy to drive on the street - Cindy even drives it.

As far as flow etc... I'm sure DRLA 48's are comparable, not sure about idf's though.

They are easy to work on - so easy even I can do it :)

And they are big and look cool - go big or go home!

Post by: red snapper on August 25, 2005, 11:57:24 AM: If its \" go big or go home\" then why do you have a mouse motor? I will admit that Im no expert in this area but from what I understand that the idf carbs are more streetable. Where the ida carbs are put the hammer down and go. So, what if I was to switch to a ida. What kinda difference would it make? I guess there is only one way to find out for sure. I think this is a good question so maybe the experts will chime in. Thanks, B

Ask SHane about the bark of an IDA - he was like \"what the F**K was that\" when I put the engine under low rpm load.

Post by: jim martin on August 25, 2005, 01:34:27 PM: decide if you want to run with decklid closed or propped open as well as if you want to run filters.
then you will know what to buy

Post by: Hansk on August 26, 2005, 01:07:03 PM: Brian , what venturies are in your idf's ? If not the same as Jame's Ida's not a fair compair . That being said I like IDA's . They do sound different and even my wife drove them on the street alot with no complaints.

Post by: James Buchan on August 26, 2005, 01:08:18 PM: I run a 40 vent currently - Brian SHOULD have a 40 minimum a 42 would be his best bet I would imagine.

You can do that with either series of carb, it just all depends on manifold choice, air filter choice and year/model of VW it is.

Post by: red snapper on August 26, 2005, 01:58:47 PM: Hey Hans, Im not really sure as to what venturi I have. I guess i cant compare as I have only used the idf carb.
Title: Ida Vs Idf
Post by: Hansk on August 26, 2005, 08:30:00 PM: I guess what I'm saying is you could or should also look at getting
some bigger vents for your IDF's as they are 48's as well and not just compair your IDF's from the box to Jame's IDA's with 40 or 42 vent's already put in them. But I do like the IDA's :D
