It might be helpful to know the stats on that bow. I have had one on my 60# GT500 Elite for a year and had no problems. This bow is 48# binary. I guess a stronger bow could break just about anything. That said, did it break or simply come apart? You have to make sure you get it fastened securely.

 

Which slide did you have before installed?
Saunders pulls the cables closer to the
rod than most other cable slides.
This equals into more draw weight and longer draw length, resulting into more fps.

 

The best I could measure with a dial caliper, the Saunders sets the cable 8.5mm from the rod and the Elite guide is 9.5mm from the rod. I put it back on the rack to see if the DW increased. Its still 46 Lbs (no change)

On my Elite bows that I installed a Hyper Glide on I had to swing the offset cable rod out farther from center than the stock Elite slide for minimum fletching clearance. That, in itself, induced more pressure on the cables thus "may" have increased the speed by a slight margin.

I see the cable rod on your bow is straight, however. So no adjustment to be done.

I must agree with the others on this one, I simply do not see a 10 FPS increase in speed with the Hyper Glide, or any slide for that matter. As one poster has already pointed out, if that be the case such a slide would sell for a high price. Bow manufacturers would be all over that one in their never ending quest for more speed. Surely they would buy out said slide manufacturer for the added benefits.

 

It increased the draw length and poundage...they've been around for a while, this isn't new ground.

 

And............?

I've had one one my pulse for some time now. Never chronoed once I put it on. I like the concept, not crazy about the way it's snapped together. I'll use it and hope it holds up.

The problem is if you attribute a 10 fps increase in speed to simply reduced friction it simply does not add up. The amount of friction you would need to have had on our old cable slide would be tremendous and probably would have torn your cables apart. Now if the effective length of the cables were shortened, slightly longer path, the draw length will be increased and the draw weight will also tend to increase. If the above sentence were all true then yes 10 fps can begin to be explained.

 

10 fps is higher than anything Ive experienced. These slides don't hold up and tend to start to rattle a lil bit. maybe 2 or 3 fps . its hard to send positive have credibility vibes with a whisker biscuit.

 

Sorry, no way! Check your chrono for consistency.

 

First I'm a big fan of hyper glides, have shot them on elites for years with absolutely no problems and they do smooth out the draw cycles.
But there is absolutely no way you got 10fps faster after installing one.

yep. was the chrono outside? probably a change in lighting.

1-3 fps increase is common. 10 fps from that change alone...not likely.

I only gain 10 fps when I changed the cams from #7 to #3. Thats a 2" DL change taking the 224fps up to 234fps. Adding the saunders in no way added 2" to my DL. Explain that one.

This is exactly my point. Think about how much stored energy you gained by increasing your bow's draw length 2 inches. Now do you really believe the slide somehow increased your bow efficiency so much that the arrow gained the same amount of energy?

I f'in showed you the chrono results, done within 1/2 hour of each other, in my garage with controlled lighting

I think this may be your problem. There is no such thing as controlled lighting indoors. Repeat the test using a light kit for your chronograph or take the chronograph outside and repeat. I don't think anyone is suggesting you are not being truthful, we are trying to say this is just not possible and faulty chronograph readings may very well be the culprit.

 

No way, chrono inconsistency

Okay. Say what you want. My bow went from 234 to 244 fps. My results over a 5 shot string were consistent. Your theories and suppositions mean nothing to me. I certainly cant change your opinions. Not even with data.

 

I say this only because I have tested them myself

10 fps is a huge increase

Of course. Your testing is obviously more accurate than mine. Got it.

What draw weight is your bow? A 70 lbs bow can overcome the drag of a cable guide better than a 46 lbs bow with just brute force alone. Lets compare apples to apples.

 

You just don't realize how much 10 fps is when all else spec wise is equal

LOL. My major is in science. I understand testing, controls, and reproducibility. Reducing drag in a system will deliver gains in speed and 4% gain is not unreasonable.

 

Good luck [emoji1360]

Ask yourself this, if it truly could add under ANY circumstances 10 fps, don't you think Saunders would market it that way? I mean, if that were true they would have it in BOLD letters on the package and they could sell them for about $60.

Any time I have had weird results like this, it was 99.9% of the time the florescent lights and my chrono......they don't agree with each other real well. Outdoors on a cloudy day for most consistent results.

 

It's the new BowTurbo!!

Did I claim under any circumstance. No. I clearly stated what bow I used and the results gotten.

 

And videoed it too. I see and I believe. You have no reason to lie, and your test were fair.
At the lower poundage, a 10 fps gain is perfectly believable. Its like a car.
Going from 30 to 40 is nothing, it takes very little additional power.
But going from 160 to 170 takes a great deal more Horse Power.
Speed gains on bows in the lower ranges come easy.
But in the mid 300s, small gains come hard.
Someone said 10 fps gain for every additional inch of DL.
That is an extreme generalization. At the higher speed ranges, this is simply not true.
If graphed; No gains on a bow are that linear. Getting close to the top end, the gain curve flattens out.
Drcoffee's bow is in the "steep gains" part of the curve.
I even doubt he corrected a problem.
All of you are comparing his gains to a 340 fps bow going to 350 fps. Its not the same.

 

Interesting. I will wait until I get new cables and then swap the hyperglide on and off with the original cable slide and see what happens. I picked up 7.8 fps with Truball accelerator balls put in the right place and it threw my sight settings all to hell. I didn't notice anything with the hyperglide.

Here again if you think about friction and coefficient of friction. A quick look at the formula involved would show you that the 70 lb bow should have a higher friction force resulting from the cable slide than the 46 lb bow, more tension, force, is trying to straighten the cables in the 70 lb bow. And again if you had enough friction, in the cable slide, to rob 10 fps your cables would not last very long!
