Anyone using Extreme velocity carb hat?

[Procharmo]

So much horse power to gained from a few inches difference in air negotiating a corner (Carb hat). Please see my thread https://www.pro-touring.com/forum/sh...ad.php?t=42500

and let me know if think an extra inch of total tubing diameter (3inch to 4 inch) from the head unit to the carb hat will net any gains.

In most cases there are two 90 deg bends at the intercooler. These would no longer be 3" elbows but now 3" to 4" elbow reducers. This must have an effect!!!!!!!! Same with the 3" supercharger outlet, it blows air into a 4" pipe as opposed to a 3". After all most folk upgrade their exhaust systems from 2 1/4" to 2 1/2" to 3" to 4" and so on for a reason. We know the effect of headers, carb spacers, air filters, heads, carb hats, intake manifolds etc so it would be nice to know what effect and how acute the effect would be if intake tubing diameter were increased?
