Toby, someone emailed me additional pics of the box on a different car. Let me know if you want them.

Please send them.

How much does this box cost?

PM me your email.

I wasn't given a price, just told to call for pricing and availability.

Hey Toby, why go with that when you can get 16 HP out of the Vipe-Error?!! /images/graemlins/laughing.gif

Unfortunately, it does not appear to work with the Gen I w/o the NACA duct in the hood!

Before this becomes an issue, I'll firmly state that we have no factual data that leads us to believe our box is worth 12 or 16 horsepower at this time. The box was tested in Michigan and we're testing it here in Florida before we release factual data. Sorry to disappoint, but I firmly believe in giving people what it is they pay for which is why we have a great reputation. Thanks!

Thank you for the honest post. It's refreshing. I still want to check it out...off to the web site! /images/graemlins/supergrin.gif

also...you need to add Viperalley to your links section of the site. :nod:

oops...your web site is not done...

so how much for this airbox and some pics would be great.

Thank you.

Would the benefit be as good on an NA car? Seems that the turbulence or bends in the tube would be somewhat of an obstruction on an NA car, but the increased area from the larger filters on a forced induction car would benefit?

Aww man,

I was really looking forward to dyno testing this new airbox as I did with the Vipair on the org site.

Please keep us posted on your testing.

MacedoMS ...did you do a primary and secondary study on the air flow through the tubes? Does this design create a increase in velocity after the curve? Does the tube have a vortex creating located before the first tube centrifugal force or is it smooth?

My first visual guess on location would be to have the tubes come into the box @ 45 degrees and not 90 Degrees to the air inlet. This way the tubes would have fewer angles and less physical study of air flow is needed.

so these bends in the tubes do not slow airflow?? i always thought a design like this would be less favorable than straight in

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.

It seems as if it would be a bit restrictive until reaching a certain speed?
Superchargers do not like ANYTHING in front of them for best flow.


No flames, but I'm probably just wrong. Looks great though! Awesome work as always Larry.. /images/graemlins/smiles

Well simple fluid dynamics will tell you that the Reynolds number of any flow will increase when you add additional bends. Increases in the reynolds number reduces laminar flow and increases turbulence, thereby reducing flow. I see the main advantage of this airbox as the ability to use dual cone filters. However since stock filters have been shown to support almost 900rwhp on heffner cars, im not sure they are a flow restriction. Damn that setup looks nice htough....real trick, nice craftsmanship.

Hello All,

Thank you for the kind words! To date we have not yet performed any Velometer, Manometer or Thermo-Anemometer measurements which this airbox. For that matter we haven't even dyno tested our airbox against a stock airbox to reach any conclusions. I do know one thing though, it sure looks good! If we really wanted to sell the airbox based on look, we would have already sold dozens. To answer your questions regarding fluid dymanics, the straight path approach is usually the one to take and usually the best which is why the factory used that design. We dare to be different and I'll be sure to post our results good or bad. Thank you!
