The PHBG is a really great carburetor for the more advanced tuner. The Race version gives you a touch more ease of access with a screw on Carb top, so you can change throttle slides, and adust your needle settings without removing your carb from your Ped.

Are Dellorto carbs any good?

As far as sides go, I prefer dellorto emissions carbs. They’re not the best for performance applications, but they still sound awesome and get great mileage. They can be tuned for most mild road cars, but big cams give them a fit.

What is idle tuning?

It is an adjustment (+/-) to that base airflow table. The STIT & LTIT add together to offset the base running airflow to keep the engine idling properly.

Which is better Weber or Dellorto?

The Dellorto supposedly has better progression enrichment, so gives smoother power/more midrange torque. However, the Weber has better parts supply, and more support from tuning companies and rolling roads. You’re probably more likely to find that a give RR has Weber bits in stock than Dellorto bits.

What adaptive idle?

When the idle timing is jacked up to begin with, idle is already making more torque and the ECM has less ability to leverage spark (and thus idle torque) to control the desired RPM. The “Adaptive Idle Proportional” and “Integral” are finer tools that the ECM leverages to control idle RPM.

What is closed loop idle control?

Closed loop mode tries to maintain a target idle speed. While not every car needs closed loop idle, it can help compensate for major changes in load. For example, if the idle drops an unacceptable amount when you turn the air conditioning on, you can use the closed loop control to compensate.

Are Weber and Dellorto the same?

As I understand it the Weber DCOE is effectively the same as a Dellorto DHLA. So DCOE 40 and DHLA 40 are basically the same carb.
