Increasing airflow will increase any motorcycle horsepower and torque. After extensive engineering and testing, Arlen Ness just released a Torque Box for the Indian Scout.
It provides a massive airflow improvement over the factory air cleaner assembly. Dyno results have shown an average of 10% gains in horsepower and torque when installing it with slip-on mufflers on the Indian Scout models (Dyno tuning or fuel tuner is recommended)
The filter of this Ness Torque Box features a hand poured to ensure no restrictive wicking material on the filter element and the best quality available. Each kit includes everything needed for simple and fast installation. Part Number P-1602. $149.95. At Arlen Ness.
I don’t know if this is considered an air box but at best headed in the right direction an item often overlooked by tuners.
For the size engine intended for it would benefit being several times larger to indicate any sizable gains.
Take a look at a Suzuki S V 650 twin {stock} producing 70 plus HP you see a large fuel tank that is mostly an air box.
Taking nothing away from this product what so ever, or for that matter any other airflow product in the market…..
Here’s the deal, all engines are designed to produce X amount of HP/TQ by the engineers that design engines, who ever the manufacture. Those engines are then released to the market meeting certain EPA requirements which of course bring X HP/TQ down about 10% or so.
Then the aftermarket will advertise and sell products that “increase” HP/TQ up to 10%….does anyone else see what’s going on here.
An engine in its stock configuration, can not and will not produce any more HP/TQ than its original design will allow. There are no miracle products.
Internal component changes and modifications is the only way to “Increase” HP/TQ
Now……
let the debate begin

If Ness made it take it to the bank! It will work like he said!!
Will it fit the Victory Octane?
@Steal You Face…
Serious or not, that was the best comment of the day!
Steve Carr,
At times I thoroughly enjoy your comments – not this time. As in I wish I can fathom the point you are trying to make.
1. Motorcycle leaves factory and produces a certain amount of hp and torque.
2. Somebody comes along and says – buy this stuff here for $150 and you will get 10% more of each while you use that stuff there.
3. You do and you get the said 10%.
4. You live happily ever after…
What is wrong with that?
In fact I went and read the few paragraphs (above) again and I do not see the word “miracle” anywhere.
Arlen Ness make some real superfluous $H1T, but they also make some really good stuff, in my opinion (and in the end that is the only one that really matters to me) this sounds more like the latter. The Scout can do with ANY performance increase (in its quest to reach the measure of a bona fide Indian Scout).
Lets not forget the best Horse power improvement is, the louder the bike the faster it is.
Endorsed by thousands. Just ask.
SIGFREED, the Indian Scout makes a bunch more powert than a Sportster 1200, please explain where it is lacking? According to Cycle World’s dyno the Scout hits 86hp vs. 62hp for the 1200cc Sportster 48 at the rear wheel. I’m not sure I understand your complaint…
My comment as stated in the first sentence was not about any particular product or manufacture.
Nor was is to say that miracles happen when a new air filter is installed.
My point was to show how the aftermarket claims to ADD horsepower and TQ, when in fact it’s there all the time just as the factory designed it to be…..
Aww Hell….just never mind, if I have to explain this it won’t be understood anyway…..
I’m out

I think what Steve is saying is what we have always known. When you get a brand new car, truck, motorcycle, there are things you have to do, to make it run as it is supposed to. Air (breathe), exhaust (breathe), timing or chip.
