Dyno results from Vipair deflector!

[GTSnake]

Well, I just got back from the Dyno and here are the results of the Vipair air deflector. I don't have my Dam* scanner working so I'll just have to type it in.

I made 4 runs. Two baseline runs resulted in 442.9HP & 472.7 Tq and 435HP & 460.4 Tq. Then I installed the Vipair deflector and waited 15 minutes to let the engine cool back to approximately the same temp as when I did the first run. The results were 452.1HP & 484.6 Tq and 446.8HP and 477.4 Tq.

It seems like the Vipair did have some impact on the numbers. I was a bit skeptical at first looking at a hunk of metal (should be plastic) thinking "what impact would this have on engine efficiency"? Amazingly, the numbers do show around a 10 horse improvement. I'm guessing because the NACA scoop only fills a small portion of the air box inlet area. The Vipair takes air from the radiator area and channels it to the area that is not being filled by the NACA duct to supplement the intake flow. In addition, the bends in the piece didn't exactly match the stock profile so I could only attach the 2 side screws and not the center one because it didn't line up with the screw boss. The paint was also bubbled in some spots but I really didn't care since it sits in an area that's not very visible.

IMHO this is a worthwhile mod. although somewhat pricy even at the introductory price of $150 for a piece of bent sheet metal (I know, I know we're paying for the R&D and not the part itself ). However I just wish it was lighter made of plastic or aluminum and not the 5lb anchor it is now. The last thing a Viper needs is more weight in the nose. In the end I think it's a keeper.

Sounds good do you have any pic's?

 

[SUN RA KAT]

Sounds like this will by a worthwhile mod for me to do as soon as the lower priced molded version becomes available.

I am curious if one could simply remove the stock plastic piece that seals the NACA duct off...easy to remove...about six screws, for the same or similar effect...ie...more air...

Regardless, I'll take one of these in black, when the plastic production parts come in...

 

[GTSnake]

Thanks Daffy for the pics. I have more pics that I think shows it clearer than the pics from before but not being a webhead haven't able to figure out how to post, yet. The deflector actually slips into the airbox which is hard to see from that angle.

Gerald, you can take off the stock piece with 4 screws but I think without the deflector you might end up sucking in some hot air from the engine compartment instead of fresh air from the outside.

 

[Russ M]

Here is my observation, I have been to the dyno several times with my Viper and on each of them I have tested the car with the hood popped open and a 80mph fan blowing into the oppening. At neither time did my car pic up any power from the normal closed hood position.

Now how can this mod do anything different? On the road the gains may be there but on a dyno I just dont see how.

If anyone has a different oppinion please correct me.

 

[GTSnake]

Russ,

I had exactly the same thinking. The fan at the dyno is nowhere near what you would get at speed. Although they did place 2 additional high speed blowers I still didn't think it would be the same as driving on the road. I specifically ran with the hood closed so to similate driving conditions. I can't explain it since I don't have any airflow measurements from a wind tunnel. Maybe someone else can. But the numbers are what they are. Maybe if I did more runs the numbers would level off and the gains would diminish.

 

[Russ M]

GTSnake,

Ok perhaps the aid of the 2 high speed fans blowing in there funnels the air into the scoop.

What were the un-corrected numbers on all the runs? Or the correction factor for each run.

Thanks

So said GTSnake

Still getting the air from in front of the rad...

 

[Newport Viper]

Have to agree with RussM, don't see how it would pick up any more power standing still...

 

[GTS-R 001]

As you all know, cold air equals horsepower. The most accurate way for a test like this to be done is with the hood closed as GTSnake did, this is how we drive our vipers hood closed. It only makes sense that the cold air from the front of the car will result in a colder intake charge and therefore more horsepower. This principle works on all cars look at the cold air kits for the SVT supercharged mustang... some claim to increase horsepower by up to 30, 10 horsepower on a viper is more than realistic and more when the car is actually going down the road.

We wil soon have some ET's in the quarter to illustrate this.

There are 50 black VIPAIR™ cold air deflectors ready to go right away, just call scott at Elite at 813 294 9886 or me Steve at 877 486 4461.

 

[GTSnake]

Yes, you are getting air from in front of the rad but it would be turbulent air. Not that I'm an aerospace engineer but that's just my $0.02.

Here's my pic of the Vipair deflector. If it loads it's due to Daffy's great tutoring. If it doesn't it's because of my inabilities...

 

[GTSnake]

Let's try this again.

 

[Daffy Duck Viper]

Hooray, you got the pic posted. That is a good picture of it. Thanks.

I have the Viper Race Induction with K&N's 'cone' filters on mine. Can I still use the Vipair deflector?

I don't know? Is it the stock air box? The deflector has tabs that fit inside the air box.

 

[RX VIPER]

I just went out to the garage. My '96 has the '00 radiator fan shroud, but that's it up front. With the cone filters with this mod fit and inc. hp in my car?

Ok, let's try that a little bigger this time!

RX,

The air deflector will fit and allow the same air flow in your car. The only thing that is uncertain is the benefits your would get from it since it seems to be designed for a factory air box.

 

[ViperJoe]

Isn't one of the marketing / selling points of this piece to interface with the stock airbox? I would think those exposed filters are subjected to a lot underhood heat?

I thought when I posted in the original thread about an injection molded plastic alternative, the vendor said one would be forthcoming, correct?

 

[GTS-R 001]

ViperJoe

Injection molded plastic is in the works. We are finalizing our molds, but this takes time and is quite expensive. The ABS plastic VIPAIR™ deflectors are at least a month away.

The VIPAIR™ deflector will help almost all the induction systems presently out there. It shouls also work with Heffner cars as well the Hennesseyy carbon fibre airbox as well, if it doesn't match we will make some that do, so all of you can use this product.

 

[vipah]

I can see no reason why this will have any effect on a stationary car. The dyno numbers seem statistically insignificant to me (7 hp difference with no changes). Maybe my degrees in Math and Physics are failing me.

I put this in the catagory of the Tornado product until more conclusive tests are run. And $150 for a bent piece of sheet metal that should cost about $20 to produce seems a bit stiff.

 

[jimandela]

All this talk of the deflector, dont forget the vipermed box itself is sweet!!

 

[Snake Bitten]

All this talk of the deflector, dont forget the vipermed box itself is sweet!!

To hell with hp, I want one just because they look cool...



I failed both math and physics...in fact...I never even learned to read!!!

 

[vipah]

How about Economics?

I'll bet we can find someone to make these in reasonable quantities for about $60. Heck, we can have them done in China out of Stainless Steel for about $10!

 

[jimandela]

Gerald,
Exactly! LOL!

 

[GTS-R 001]

Vipah
The hood was closed as in everyday driving. The stock airbox as well as others **** some cold air from the outside through the NACA duct but they also **** warm air from just above the rad. This product allows cold air in place of the warm air as the fans were placed in front of the car, just as the wind blows when it is driven, the procuct therefore allows more cold air to enter the engine and therefore produces more horsepower. Try one if it doesn't work full refund!!! And hey if it sells like the Tornado does( I only wish )

JIMANDELA
The full cold air box is a greta product and it is good to see someone appreciate all the hard work that goes into designing and manufacturing a product like it, you will be very happy with yours when you get it.

It is for people that think like this that we filed a patent app, copyrighted the design and trademarked the name.
Also, I presently manufacture over $20M a year worth of merch in china every year so tell me all about it!
