Question on Air Box ?

[Snowmobile Mike]

I have a 2016 Viper XT se, I have been reading about do it yourself air box mod by Stingray, I dove into it late this afternoon and Opps ! I cut wrong area ! I took snorkel off and cut nose off under snorkel !Had a major senior moment not going to look at pictures again before I started. Should I cut out area in front off nose ( area that has been shown in pictures ) area that has been suggested and give it a whirl ? ? ? Or am I asking for trouble does nose under snorkel direct air in a way that without it it will cause major issues ? Or do I need new bottom of air box ?

Can you take a pic of what you cut out?

You can also find stock airboxes on eBay, or even here in the classified section for around $50. Even if you need another airbox and the. Do the mod correctly $50 is less than an intake from any of the aftermarket suppliers. A picture of what you cut would definantly help.

I hope pics come thru, not sure how to get them up ,I'm trying now.

 

[cannondale27]

They came through. I would keep cutting. The part triangle part. Then try it. You still have the snorkel? It could be welded back on. Its a big enough piece that if it falls off it wont get sucked in. But honestly I would just try it without.

Still need to cut out this area. This is where most guys mess up the screen so either get a replacement screen,be careful or just remove and glue it back on. Windshield adhesive or Permatex Ultra black works great for gluing screen back on. The welding can be done with a heated up old screwdriver.

How does your divider look? The flat piece that lays in the upper part of box. Cracked?

I miss the old Dynotech days when they would take a mod like this and evaluate the outcome.... All aftermarket guys too... I haven't heard of any?

Cant really test this mod on a Dyno. Needs to be airflow at speed. Just try it. It works. Like said will notice Mid Range increase like coming out of corners.

Sure. But how can it be the same? Flow bench results would be more realistic but even that is not same as real world.

 

[cannondale27]

Sometimes its just easier to dig in or just live with what you have. I understand both ways.

 

[cannondale27]

Its not like you are riding or this costs any $. Just time. Maybe a little risk. Your call.

This modification makes a noticeable difference. Which is why I think I’m going to make / buy a cold air intake that actually pulls air from outside the cowling. If this little free mod makes a big difference then pulling fresh, cold air from outside the cowling should be a huge difference.

Sure, I just look at the fact that Yamaha , Ford , Dodge ,whoever could put a hole in a air box and some velocity stacks for basically nothing if there was a benefit. No dispute here just would seem they would be wondering why they missed something like this mod and the public could do better? I have seen where air boxes have been opened up and because of there design they flow less air with the interruption of the mod.... (tested) Seat of the pants is not most of the time faster with say clutching changes that's why they use timing systems for example. Always understanding the parameters they must build within is the only way I could see this. I will see this mod myself this winter as I will have at my finger tips two identical vipers to try only difference will be the air box mod on one......let ya know.
