Tested another idea at the track the other day. Thanks to Mark Peachy (quicksilver99) for his fab work in this project.
Wanted to get the air from the front of my car "lined up" and forced into a velocity stack styled intake. Came up with this idea;
![]() 
Right now its a rough experiment but I did get positive results.
I started off with having Mark make some progrssive piping for me;
![]() 
![]()
I of course cut the hole in the bumper and then cut down the pipe to fit in;
![]() 
Then my racing buddy, Mario, welded on a cone (again from Peachy) to the end (I would rather have had a velocity stack, but that would have been much too expensive for experimental work);
![]() 
Bumper with a plastic trim ring/velocity stack put in hole (the way I wanted to do it):
![]() 
So ran it at the local drag day. About 4 runs without and about 4 runs with. The results were a definitive 1mph+ more on the traps. Not only that, but absolutely more pull after I crossed the line. Pretty cool results.
Now did I log it? Well.......I intended to, but didn't because, well, sometimes things just don't work out that well at the track. I really wanted to log vac to see if I was getting any positive numbers. Someone I knew did something like this and they actually came up with positive numbers after 100mph. Hmm, a boosted NA, lol? I won't tell you who, I'll let them come on if they want, otherwise we'll just consider it heresay.
Now if I expand on this, I will do a couple of things differently. The pipe at the throat is only 3 3/4" ID and it tapers down to the 2 1/2" throttle body size. I would like that to be more a 5" throat that tapers down. Also, would much rather have a velocity stack than a cone.
So experiment a success and a new addition to car.
