WE HAVE BW-44 BW-47  BW-55  BW-62 USEING SAME secrets AS BW-230 XL CAM 
This dyno graph above shows just how fast BW-230 xl cams make power(the green line)Take in mine that this is using stock HD pipes with cross over 883to1200 the red line is experimental cam and takes 2 seconds longer to get to the test RPM has a little more bottom end but the BLUE line Screaming Eagle 256/260-.536″still takes 2 seconds longer than the experimental cams.
You can also notice that there is flat spot in same aera for all runs when we fix or find that problem then we can make a better cam yet. 
The best Screamin Eagle cams can’t compare, we gave up 2 foot pounds of torque we still make power faster ! -Four seconds over the SE 536 camshafts,  that could mean saving your life if you had to get it on!!!power faster means you win and get to the next red light quicker or down the race track than your friend with the other guys cams. We know that we can get back 1-2 Ft Lb of torque with a little tweaking. So Don’t be fooled the next graph down shows how you are fooled by using rpm only it looks like the cams are equal in making power but they are NOT!!! People lie to you and won’t sell you our cams because we are not famous or something -Well this should have enlighten you. MAKING POWER IN A SHORTER TIME MEANS MORE POWER TO THE GROUND QUICKLY!!!
IF BIKE A HAS 100 /100 AND BIKE B HAS 100/100 AND BIKE A MAKES THE POWER 2 SECONDS FASTER WHICH WOULD YOU RATHER HAVE UNDER YOUR ASS???

This lower graph shows true superflow dyno numbers on stock 96″ with dual exh. & SE air cleaner using TTS software ( master tune) 
now these numbers would be even greater on a dyno jet dyno-imagine that!!
 
 
 

BW47 Vs 2007 FLHR show the power gains by just using our cam and a TTS tuner over 20% gain-So why don't you have a Black Widow cam in your bike? Probley cause no one will tell you that we are here in Littleton Colo. for ten years now and our cams out preform the other brands- But you are forced to buy what they want to sell you and they don't give you the option and not all Harley-Dealers are a Black Widow Dealers. We here at Black Widow cams will install and tune your Bike to make this kind of dependable power.
