The following is a post I made on Viper.org, There are pictures there also it is under "Macedo Motorsports heats up my engine bay." I hope to be dynoing the car in the next two weeks.
We have not re-dynoed the car yet, the car did run it's best at San Antonio of 11.03 at 129.53 mph with this airbox, previously with the old airbox we went 11.18 at about 127-128 mph, on some of the runs at San Antonio our time was worse due to launching on drag radials, but the car ran over 130 mph. There were some other variables though, different track, air was a bit cooler. One of the things I like best is that with the wider supercharger inlet tubes it takes the pressure off of the smooth tubes and the old air box. Before it was like wrestling with a Sumo to get the tubes on and off and I broke more than one airbox trying. This box will fit many different setups, throttle bodies tubes etc and it is much easier to take it in and out. Plus it looks great especially through the Naca duct, also the whine of the supercharger is slightly more audible, sounds great.
