Its all show and no go.......

 

Here's a review I got from a very seasoned v-twin indy (30+ years wrenching) that explains their flaw:

Because of the way the air travels into the front and out the rear of the Hyper-Charger, instead of forcing air into the carburetor, it actually pulls or "siphons" air (and fuel) out. As a result, you get what has been described as a "dead spot" or lack of power at highway speeds, not to mention the fuel breaks down the oil in your air filter hampering it's usefulness and the fuel mixed with air filter oil tends to deposit itself all over the right side of your bike when you go on long rides and then when you stop it all drips down on the cam cover, your foot, that cigarette butt you just dropped, and so on.

I trust his judgement & he has experienced this problem many times w/rides he worked on throughout the years...

 

I honestly don't think the hyper charger adds much in the way of performance...But every time a dyno operator tells me they don't do a thing...I have to ask...How can you tell it doesn't anything if the bike is stationary during a dyno pull?

 

It is not the Hyper charger that does anything, it is the K&N filter in it that breathes better than the stock one it replaces. The body of the unit is just for looks as it mimics the breathers on hot rods back in the day.

By the way since my son installed it in 03 and put 18K on it. It has never did one drop of anything as the so called 30 + year Indy reports. Must call BS on that.

 

There's a reason the word HYPE is used in the name. imo

I had one on my '96 Evo RoadKing. Now, I bought the bike used from a guy who was NOT the original owner, & it was already on there,and I had NO idea whether the motor was stock or totally built. All I knew was 2 things--it had a Mikuni carb, SE pipes, and it was, out of all my 18 Harleys, the absolute fastest Harley I ever owned (or rode). Did the Hypercharger help? I dunno; maybe it would've been even faster with a SE air cleaner. All I know is--it didn't seem to hurt performance any. I thought it looked a tad tacky,but the butterflys were kinda kitchy & cool,opening & closing like that. Would I intentionally put one on my bike now? No.

I think the biggest problem with the Hypercharger is that the name is misleading--kinda makes you think it's some kinda "forced air" intake.

 

had one on an 04 heritage,piece of crap and replaced it with a screaming eagle.

 

the front of the hypercharger is no where near close enough to the airflow for any 'ram' effect to take place. any ac is gonna be subject to that.

thats also why you can ride in most rainstorms with an open air element and not have any problems. though i did ride in one rainstorm with the rain coming down at about a 45* angle from my right side that did give me some problems, once....

 

I've known several people that have had the Hypercharger on their bikes, both evos and twin-cams, and the type of problems described above were never an issue...

 

Do you have an pics? Sounds cool.
