No. The only sensor on the airbox is the intake air temp sensor. Cat's fuel delivery is somewhat of a guesstimation and really isn't too sophisticated. A speed density system with a MAP sensor or a MAF system would be great along with an O2 sensor for feedback. Problem is the pluses caused by the engine would screw up a Mass airflow sensor and a MAP sensor wouldn't get a true vaccum reading.Originally posted by morrisond@Dec 13 2002, 10:59 PM
Does that mean it has a mass airflow sensor to compensate for the increased airflow?
Good question. I don't think it will. Others might disagree. Reason I believe it won't run leaner is it will only change the volume of air available. Added volume will increase volumetric efficiency at higher rpm, thus allowing the engine to make more hp. And all engines suffer as RPM increases.Originally posted by morrisond@Dec 14 2002, 12:21 PM
So changing the neck will make the motor run leaner. right?
On the carbed F5 that makes sense. By comparison using D & D's powerbreather they wanted you to increase the main jet size and also install the caps on very cold days.Originally posted by byoffcr@Dec 14 2002, 06:13 PM
I think it will or why does D&D sell caps to put on when it gets down to zero so vents are closed off
Less then ideal and more effective modifications are possible.Originally posted by byoffcr@Dec 14 2002, 10:34 PM
When you cap off the vents you run colder air and less volume..You are shutting off air from under the hood not out side air
