Stock ltd, or NPS plastic bolt mod.

The face of the LTD bolts is rather small, and doesn't cup the ball very well...this causing chops. Sorry for the lack of pics, but I will try to explain this as good as possible.

What you need first is a pocket knife. Take the knife and port out the hole. Which means sticking it in the face, or hole in front of the bolt at sort of an angle and twist clockwise, or counter clockwise. Even stick it in vertical, but don't twist too hard. After you have ported it out. Stick the knife back in the hole, and round it off at the top, inside of the hole though, to help it better cup the ball. The hole should now take up about...half a centimeter from the top to where the groove is for the detent. It's is still reinforced at the bottom, because all you did was make it to where it would cup the ball. After that, take some sand paper. Tear off about an inch, it doesn't matter the grit. After taking off an inch, tear it in half long ways. After doing so, roll it up very tightly as you were going to roll a cigarette, or a rug up. Stick it in the hole, and twist it until it is smooth. In theory, this should help with chopping. My friend will be testing this in his wrath soon, with my modded bolt because I no longer have an LTD, just the bolt. Will keep you all posted.

EDIT:
^BEFORE


^AFTER
Compliments to ESP.

Another thing mentioned by grivooga.

Another thing I did was fill in the area behind the inlet port inside the bolt so that it is a nice smooth curve. When they made the stock LTD bolt they drilled past the inlet port on the bottom. This creates a space of wasted air and the sharp reliefed edge should create unnecessary turbulence. I filled it with epoxy then shaped it back to a smooth curve after it dried.

So you mean instead of this



It's more like this



Is that right? I've thought about doing that before but I didn't want to risk it because it could change efficiency, fps, and all that stuff so I didn't do it. Did you notice any change?

Exactly like that. I still haven't gotten a hold of my friend, so we could do this. Many people do it on their spyders to help it better cup the ball though. It's nothing new, and it works good on spyders. Why shouldn't it on the wrath.

I just did it. I see what you're saying and I think it will help efficiency because the air flow will be restricted less and less air will get around the ball. We'll justt see what it does when I go balling next.

When you did it did you cut into the detent slots? Because it's like 2 mm away from the hole.

I'd already done this to my LTD bolt (seemed pretty obvious) though I hadn't done it to nearly the extent as shown in the little diagram. I just put a 2 mm chamfer on the edge with a counter-sinking bit. Then I broke the edges with an emery file.

Another thing I did was fill in the area behind the inlet port inside the bolt so that it is a nice smooth curve. When they made the stock LTD bolt they drilled past the inlet port on the bottom. This creates a space of wasted air and the sharp reliefed edge should create unnecessary turbulence. I filled it with epoxy then shaped it back to a smooth curve after it dried.

Honestly didn't notice any difference. Can't really say I've had any issues with my LTD at all after I got it back from NPS shortly after I bought it because the LPR was acting screwy.

Made sure not to hit them.

It was really inconsistent and I couldn't get good velocity without turning the LPR all the way in and raising the HPR. Had problems with hoses blowing. Really a PITA. Turned out that my HP gauge was way off from the factory (yeah it's obvious in hindsight) so when the gauge said 300 it was actually inputting 200ish. Of course I couldn't get good velocity at 200 input and with the LPR turned in all the way to compensate, of course it was blowing hoses. It's bloody obvious looking back on it. I know (and knew then) that the gauges aren't very accurate. But it never occured to me that that was the source of the problem. Eventually I had to send it in because I bent the pin in the LPR and the o-rings got torn up from disassembling it so often. NPS patched it up and sent it back. Now I set my HP gauge to read 350ish (which is 275 or so actual pressure) and it works great. Modified the bolt because breaking that edge seemed like a reasonable thing to do and filling the inlet to be nice and smooth just made sense to me.

damn im having the same problem with inconsistancy!

hmm i might just buy a new gauge seeing as that the stock ones arent very accurate.
