IDF or IDA?

I was just reading on the aircooled.net site... it says that IDAs were meant for race applications (though "these do work very well on the street").

The IDA is a physically much larger carb than the IDF. The IDA was/is usually used in drag racing applications where only idle and full throttle are used. IDA's lack (in stock form) the proper progression circuitry to be driveable. They can be modified to perform very well . IDA's are also more exspensive IDF's are more street friendly out of the box, but don't provide the performance potential of the IDA's.

Short answer IDA's Hot street car or drag car, IDF's will work on anything from a 1600 stocker to a 2L+ Stroker

Both can provide performance and economy, when set-up properly.

Wow! Look at the price difference between the two! More than double.

BTW, Ryan, cool offroading pics with your baja.

That's the best reason I have to get IDF's

Heck, I'm "in the business" and even I run IDFs on my street cars. The performance difference in 99% of the engines is similar. IDFs have filters that fit, it's easier to change plugs, they drive nicer, they are less $ (for the carbs and the spare parts), and a guy I know did dyno test on both, and most street engines make more power with IDFs.

Thanks dude, I really need to document more of my "Adventures" though. :-)
