what is the best way to adjust the velocity on an evo x autococker and what is the best input pressure? 
thanks

velocity adjustment on a cocker
- Thread starter smartecosse
- Start date
If im not mistaken the evo x has a rex nelspot as standard, which means you can adjust the velo by putting the correct sized hex key through the hole on the back block and into the hole next to the cocking rod. Should be clockwise for up.....you can guess what anti does. Hope this helps. As for input pressure i think between 3500 and 4500, could be wrong
Gurney - you're not mistaken, an Evo X has a rex dialler kit, but it's ANTI-clockwise to take the velocity up - due to it working on a worm-drive, the rex kit is opposite to just about every other marker out there.
Input pressure? If the marker came from Belsales with a front reg, they're usually set bang on - I've heard of people running them as low as 200 psi, but if you get high rates of fire then you want the pressure a bit higher to prevent starving.
My evo classic runs at 450psi from the WGP vert reg, but I tend to run at high rates of fire for the whole game with my race-grip

thanks - so if i set it at 300-350 should be ok and leave the rex as it is. one othet stupid question but i've never had a cocker before, what's the external adjustment knob on the Twister kit actually adjust!!
What it is supposed to do and what it actually does are two different things, it is supposed to lower the cocking pressure by a given % a larger % on non evo-ed cockers but either way the most it does is provide you with exercise for your fingers cos mine doesn't do squat, all in or all out or any point in between although I have seen one operated and it actually stopped the cocker cocking so some work most don't. It looked good so I bought it, and the Airsmith who setup my cocker (John Bonich) said he would fit it but it was a waste of time, given to how much work internally he had done on my cocker.
lol hmm
just wondering so eventually when i get mine im not asking the same questions. and i bet that sounded stupid diddnt it?(here comes the anger)
lol i never owned one befor eaither or yet, but are we talking about that knob in the front of the gun under the barrel or is it something completaly different?Originally posted by smartecosse

Yes you sounded stupid... again but yes, it is the knob under the barrel.
The twister kit should adjust the pressure that is supplied to the ram and therefore the pressure that cocks the 'gun (the figure 100 is bouncing around inside my head). I have a Shocktech FGP reg on one of my cockers and that DOES work.
In the olden days (when Rancid was still crawling through the woods!) you had to turn the reg right down before you gassed up the gun... every time!!! If you didn't, the LP hoses blew away with the fairies
If your reg is working you need to set up the 'gun by turning it all the way out, gas it up, pull the trigger and turn the knob in until the 'gun cocks. At this point, cycle the trigger (fire) until the gun fires and cocks with each pull! Then give it an extra 1/4 turn for good luck.

smart, gonna hijack ur thread for a bit for my prob aswell,
i have an evo 97, and is it the same way to adjust the velocity as flash-bugout said? or the evo x??
cheers

cowface: possibly, possibly not - the way to spot a rex-dialler kit is firstly a hole through the back block, just to the left of where the cocking rod goes through. If this hole isn't there, then pull the back-block back and look at the round lump of metal that the cocking rod goes through (this lump blocks the bottom tube in the body if that makes sense). If there is a little "thing" to the left of where the cocking rod goes through, which looks like it takes an allen key, then you have a rex-kit, and the velocity adjustment is as I said earlier - if not, then you have a standard dialler, and you need to take out the cocking rod, put a large key in that hole and turn clockwise to dial up.
That probably would have been explained easier by saying do you have a fat or thin dialling key
Smart: as for setting the pressure, there is a trick to find your cockers optimum input pressure I have just re-discovered.
Dial the velocity adjuster all the way out (in your case fully clockwise).
Turn the pressure on the LP reg right down (probably safe to start at about 180ish), then, in small steps (this is loads of hassle with a WGP reg, and you're about to see why)
turn the pressure up until the velocity starts to come down again*
you want the input pressure which gives the highest velocity.
Hopefully this is within 30ish fps of 300, or you need to change springs (a heavier main spring I believe).
Once you have your best velocity set using the pressure, fine tune it with your rex-kit, and you should be rocking.
*The theory behind this is that once the pressure inside the valve gets to a certain level, your springs/hammer combination do not have enough push to open the valve far enough/for long enough to allow enough gas out.
