Are they the bastard child of the Weber family or what? Anyone running them or have experience working with them? Can you still get kits for them and what parts fit them jet and vent wise.

I use them all the time. You can buy them new, and jets are the same as the 40's and 44's. I've even got a pair on my street car that were modified by JayCee, and they outflow IDA's.....much more compact, and the progression circuits are much nicer than IDA's.

What did JayCee Ent. modify to the carbs? |

48IDF's (or Dell 48DRLA's) are hardly the bastard child. A bit more civilised (more progression holes), a bit easier to work with as far as parts and linkage being universal to the IDF family, a little easier to fit into certain engine compartments and a bit less costly than IDA's.
But Weber 48IDA's will forever be "THE" carbs to bolt on to air cooled VW engines.

My IDA's rebuilt at ACE worked great at the Flats. I had a smaller engine in a heavier car but the carbs made great use of the flow that the heads provided and the Ghia was fast.

Hey Britt,
I have a chance to pick up a set of IDF's pretty cheap, so that's why I'm considering it. These will go on my new motor, a 2332, Street Eliminator heads, FK?? 10:1 comp. and go into the Beetle I'm planning and gathering parts for right now.
Ya, your car was flyin' at Bonneville this year, till that little problem with the carb manifold  What were the specs on that motor Britt? Sure sounded good!!!

| Since you're an EMPI fan, you might consider the 48 IDA knockoffs. I'm sure they're cheap. |

Almost any part or kit for any Weber carb can be found here...
http://www.piercemanifolds.com
Mike is major west coast (US) dealer...
I ran a a pair of 48IDF's on a 2180 for a while and they tuned just the same as a 44 IDF..... Only problem my cam and compression ratio was a little light for carb size, dropped back to a set of 44IDF's and engine ran better, but that may be just my engine...

I'm not an EMPI fan, I'm a fan of parts that work, do the job I want them to and save me money. Those pr the 51.5's are my second choice. They're not cheap, but they're cheaper. They're still over a thousand bucks here in Canada, add another 50% for "real" Webers

I love my 48 IDF's. I have a 2276 with FK-44 cam and DRD level 7 heads. I actually tried a nice set of IDAs to compare and while they look and sound cool, I sold the IDAs went back to the 48 IDF's. Just by the seat of the pants test the 48 IDF's made similar/comparable power. Of course ever combo and case is different and I was strictly street.

The bodies are bored, the butterflies are 49mm, the stacks are from 50mm DCOE's, and the vents are now 45mm.They flow almost as good as 51.5's according to BERG's flow bench....it depends on the vents....

Thanks for the reply. Now I have some options to consider as I have a set just sitting that needs to be rebuilt. Original plan was to rebuild it and sell it, now maybe not. |
