A few more questions, just to confirm, no idle problems? No low end power loss? No surging? If these are all no, you have me sold...

the trick was the correct cross sectional width and area, along with the right profile leading into the apeture. that combined with a some other details wroking in unison makes for an efficient unit that improves airflow with no restrictions. by using a manometer on both sides of the throttle body during testing we could determine that different designs posed pressure changes in positive and negative fashions. it took a while of testing to determine which was the most efficient overall design to go with. by using a different style of shaft bore, and multiple sealed bearings, there isnt minimal side to side movement, and no vaccum leakage thru the shaft bore or bearing area. on a stock TB we could measure more leakage here, which leads to vacuum leaks, and on a boosted engine, another source for pressure loss.
no to all, except it works like a champ.
a few of my customers have given me testimonials with their email if you would like to ask some of them how they like it.
i appreciate the valid questions, it helped me to put into words, what i need to properly explain about our throttle body. i love this forum!
