Velocity Stack ?

AFAIK, the main attribute is the airflow is less turbulent when using a 'stack. The air enters all basically flowing in the same direction as opposed to having the air enter at all sorts of angles. Even a gently radiused air filter base will help things in this regard- the stack is (to me) like the 'ultimate' base.

The velocity stack directs the turbulent flow of air to the carb. I've never used one on my cars but have used them on motorcycles with big success. It's amazing how much increase in power you get. It also depends on the length and opening of the stack. I found the slightly longer stacks worked better, again I'm relating to motorcycles. Same principle tho... I recall they made excellent bug catchers too...

Thanks for the response guy's. The stack is 4 1/2" tall, 8" across, and fits nicely under the hood of my truck. With the dual screen and filter element, there's no bugs going to get in it, that's CREECH's job up in Alaska with that big fly catcher on his poncho hood. I installed it this morning and it was in the 30's outside. I also have a manual choke on the 600cfm and after about 5 min. of warm up, I didn't have to use as much as I normally do. I thought it would be the other way around but I guess the primary boosters are getting a good signal. It's soooo much fun when an engine responds to very little thing you do. After another 10 min. of cruising around town here, I could tell a difference in how smooth it accelerated and it felt like it had just a tad more torque in the bottom end. Full throttle test will be this afternoon on the way to work. I opened the hood when I got back home to check that all was correct and the motor doesn't look like it belongs in there
anymore. I might (depending on the weather) clean it up some and take a pic of it. Thanks again.
