View Full Version : Low Pressure Spyders, how low?

04-09-2006, 09:57 AM
Im sure this has come up before, but Im new here. Basically, I want to know what the lowest pressure Spyder out there is, not counting ones converted to ACs or Timmys (such as The One Kit). So, must still be open bolt blow back. I have heard of a 225psi, has anyone gotten lower than this? Also curious to know what parts went into it. I am at 350psi with modified stock bolt and valve, polished internals, 32 valve pin, Lapco BigShot (I dont think its too well known but barrel choice is important for LP, you dont want a lot of porting).

OK, I just made a list of my gun's specs. It was before I stopped using it and sold some of it. I loved it, and it was efficient. I could have possibly went lower pressure, but then it would possibly make it less efficient, and this beast was friggin' efficient.

Marker: Spyder Imagine
Barrel: 12" CP 2 Peice
Feedneck: CIP clamping
Hopper: Zeggy
V/A: 15* High-Flow Assault Block and 600psi Planet Eclipse gauge
Regulator: Bob Long Torpedo
Drop Forward/ASA: North West (NW) Drop forward with on/off and DYE 1,500psi gauge
Trigger Frame: ESP 3.0 with custom-made trigger, Dye Sticky 3s, and 50g switch
Internals: Otterized bolt and striker (polished and venturi removed), stock valve
Air System: Pure Energy 48/3k HPA tank
Operating Pressure: 220psi@275fps

Wow that seems so odd to me that you can get the pressure that low with only modified stock internals. How many shots do you get out of your 48/3k? I get over 1000 with my 20oz, maybe as much as 1500, but probably in the middle somewhere. Im curious to know how low you could get your pressure if you added an AKA bolt or better valve. Im also curious to know if your guage is functioning properly.

well a normal person with a 48/3k gets about 480 but .. Tim gets about ... 850 or so ...

Nah, about 750 was normal. I have no idea how I got it that low lol. I just kept turning down my OP so it would shoot at 275fps with the velocity adjuster all the way out. Don't ask me how I did it...it just...happened. :confused:

I was running my TLX 220-240 psi @285fps, consistantly. I had a rocket valve, BL/32 Degrees High flow VA and LPC, BL Torp Reg, DH Titanium Striker and a Kingman ACS Delrin Bolt.

I had an Esprit...here were the specs:
Madman Rocket Valve
Trinity -10* VA (modded for high flow)
BL Torp reg
madman spring kit
shocktech supafly bolt
Nightstriker XL

Recocked at 175 psi...the lowest my torp would go...set it at 200 psi/279 fps

14" Teardrop
NDZ valve
Polished striker sear etc.
Stock VA with the asa part drilled out entirely with 0-700 psi gauge
Palmer Stab
ACS bolt

Won't recock below 450... :'( I assume here that its my VA, because people with similar setups other tha nthe VA get great low pressure... Gettin the Assault Block.

My Imagine runs at 20psi @ 300fps and I need to lighten the springs a little to lower the velocity. I have modified the valve to a kanooten high flow ignisive type design and replaced the steel striker w/a newly innovative Rosegrotten ceramic one to get this amazing results. I have bored out the upper and lower tubes and hot/cold inserted 2 teflon impregnated tungston tubes to minimize any friction factor to +/- .050 kryptometers(that means very little). The specially fabricated tank uses atomized oxygen as a propellant that works along with the kanooten high flow ignisive valve that sparks a whopping 10,000 shots from a 4oz sized tank. Yes, you can even BBQ chicken at lunch s/a the Tippmann propane version. I keep the universal uncapped uEQ WAS board(the size of a dime) that has 10,000 mode and setting choices at 40bps. It is fed by the Akita boarded 75bps capable Akita Krypton II hopper that has neoprene paddles and has shells made of almost indestructable zytel plastic. Holding this amazing hopper is the 1/64" high CCM super no pro prono feedneck(can't get any closer to thr breech than that). Now.....let's see someone beat the person that undoubtedly has the biggest Spyder marker babalones on the forums -
