SC'd Victory low velocity

[BrainEmindless]

I cant get my victory to chrono over 260-265. I have a pressure tester and set the regs to 80+200. I defaulted the board and replaced the battery. The paint is a slight underbore and I am shooting Graffiti. Same tank, barrel, and paint works fine on my Vice. I bought this gun used and it works fine otherwise. I played around with higher dwell settings but it helped only marginally. It is fairly consistent ball-to-ball but I just can't get the velocity up to where I am used to.

Rebuild and relube the LPR.

[RapperAsInTheGun]

make sure you don't have lube on the top or bottom of the doughnut, just on the o-ring. too much lube on the top/bottom of the doughnut can make a poor seal.

[Redakuma]

check outer engine orings and replace

[BrainEmindless]

The LPR looks fairly clean. I have an o-ring kit on the way. I have not found any o-rings that look bad (in the poor lighting anyway)
I plan a complete o-ring rebuild since I got it used.

Wouldn't lube on the front face of the doughnut just cause a leak down the barrel? Not low velocity.

[the incubus]

Tear the Marker down and rebuild it using a better mixture of lube. Mix 1 part Dow 55 to 2 parts dow 33 and then mix in a touch of Tri-Flow Oil.
33 is slicker and 1 part of 55 provides enough of the swelling component to do the job. Adding the Tri-Flow makes things a hair smoother and slick.
Tera down the entire thing, CLEAN every nook and cranny well (I like to use a toothbrush in a bowl of hot water and Dishwashing soap, using the
toothbrush to brush away EVERYTHING including existing lube/grease/oils/dirt/debris) so I can then re-assemble everything properly.

FIRST, you are supposed to place lube in the O-ring Groove BEFORE installing O-rings. This serves to purposes...

1. O-rings aren't all so perfectly round and by placing lube in the grooves, the O-ring is forced to be more symmetrically perfect being as the lube
will push the O-ring out and will give just enough to allow for a tight and more uniform seal all the way around.

2. Since O-ring grooves are square and O-rings are round, the lube that remains in the corners of the grooves help serve as a reservoir which
keeps O-rings fresher for longer and keeps adding to the lube as it is used up.

Once you Lube the Grooves (only a small amount is needed) install O-rings and then Lube as normal. (Sparingly as GLOBBING it on their the way
some people THINK is better can actually prove to be counter productive). The MARQ is Enclosed so it will not be nearly as much of a magnet for
dirt and debris but excess lube can get sucked into hoses and air passages which is not ideal.

Try these things and see if your velocity doesn't shoot way up over 300fps with ease.


BTW, I call this concoction of lube Formula-44D and is the ONLY lube I use on ANY of my Markers and have yet to ever have a single issue.
I have previously kept this little secret to myself but I figured why the hell not share with all my Bob Long Brethren.


Enjoy!

Good stuff right there! Time for me to make a little mixture up!!

[BrainEmindless]

Thanks for all the info. Formula-44D- Nice! sounds like a winner. I'll be back after the rebuild and test. Would love to have it running right for the Easter game.

[BrainEmindless]

I was able to get a little more velocity out of it but I was unable to replace all the orings. The kit I ordered was a little short. I also found that the manual I have has some inaccuracies as well. What size should the (outside rear o of poppet shaft) oring be? The manual says 10 but it is way to big. The oring that came off is not even close to anything in the kit I received. I am not even sure whether what was on there was correct. Maybe the manual does not match the SC kit but I still need to know. I am running short of time for the Easter W/E game.

[WillyW0nka]

My old victory wouldn't chrono over 220 fps with a low pressure tank, and using a high pressure tank would blow the o-rings out. Had to run it at 500-600psi in order to get it shooting up to speed.

Your problem might just be orings, but in the event you try EVERYTHING and it still doesn't work, maybe give that a try.

[BrainEmindless]

I may send it to BLAST. I will for sure send it to them before I run it at 500PSI.

[BrainEmindless]

Got it back from BLAST. Aside from o-rings, they replaced the donut. I aired it up and hit 300 first shot. Only problem is now wihen I get on it (ramping 12BPS) the back block works its way up and has blown the engine out 2 times. I taped it after the second time. I checked the pin and it is tight. I am getting fed up with this victory. If I didn't want to shoot it I'd just sell it to get it out of my sight.

How long does 44D last for after combined? or do you only make enough each time you lube up the gun?

[Herk8240]

There shouldn't be an expiration on the lube. There is a shelf life but as long as you don't make a 55 gallon drum, you should be fine. You may have to mix it up a little if it separates.

Wow, that's ridiculous. I'm wondering if maybe the pressures are wonky or something? If it's got brand new o-rings and fresh lube, I can't think of much other than it needing to have regs balanced and dwell adjusted.

Rob you should sell this or just send me some! Buahahahahahahah!!!

[the incubus]

I've actually been thinking about it for a while now. Would just have to buy new mixer attachments for my Blender as I would probably make a large enough batch of it that I'd use 2 full tubes of 55. Then I'd package it in my empty Bearings containers which are roughly about the size of a packet of smarties. The one in my toolbox has lasted me over 3 years and is still more than half full.

FYI, this is pretty much what Lurker does for his lube though it consists of other lubes rather than my mixture.
