44 idf weber

sen2two · 11-04-2010, 12:24 PM

I been looking at a few 44 idf webers for my streetported 12a. Its a street car, and I drive it daily. I have a holley 600 on it right now, but it's just to big of a carb. So i wanted to switch it out.

I have been told the idf carbs are better for street and drivability and the ida's are more for racing. is this true?

Also, if i ever wanted to build my 12a and do a bridge, would the 44 idf be able to handle it? or would it choke the motor?

The IDFs have a provision for a choke, not sure if its manual or electric.

The 44 may not be enough for a bridge but I'm sure its good for a stock or
SP 12a.

The 44 IDF should feed a stock or streetport 12A no problem. I have a 48 IDF on my halfbridge and it is choking the engine out. The IDF is a nice carburetor for just street driving purposes and possilby light race use. They do have a choke provision but that can easily be stripped out and a block off plate made or bought for it. Mine is very smooth even on the halfbridge. Car idles at 1000rpm and is smooth all the way through the power band.

Food for thought... There are dual IDF intakes out there for the 13B. You could buy another 44 and run a twin 44 IDF setup for the future.
