E*TEK Efficiency Test Results

Ok so, we al know that E*TEKs have lost the QEVs and what not.So just how good are they without them? Jack Woods from PE has done a test himself for us all.

-----------------

OK, so I know a lot of people have been asking about efficiency of the ETek, so I thought I would run a little test to get some exact figures for you.

Test conditions were:
PMI Pure Energy High Pressure 68 cu in Tank
Tank Fill pressure (after cooling off) - 4200psi
Paint Sterling Rec
Barrel - ETek 13" Barrel
Dwell - 11.0ms
Fire rate _Varied between 5 bps and 17 bps (to simulate game)
Feed System - Reloader B Speed 3
LPR Setting - Flush with front cap
Initial Velocity Setting - 275-282 fps


This ETek was taken straight off the production line and had never had a ball fired through it. I set the velocity using the in-line regulator to the velocity shown above. Fitted the tank and the loader and started the test.

Result = 1450 shots

The gun was still firing at this point, but the velocity had dropped down to 220 fps so I stopped the test there. 220 fps is still a usable velocity, but below that seemed pointless.

I am very confident that the ETek should display virtually identical figures to the Ego6 in real-world use.

Cheers

Jack Wood

To everyone who was previously dissing PMI tanks, Jack Woods apparently condones them.

LOL apparently.

Anyways, those are some impressive figures for a NIB. Imagine once that thing breaks in and you're able to turn the LPR in and lower the dwell.

Glad to see the E*TEK is performing well.

it's already quite popular. now the people in the 600-900 price range have another choice. and a very good one at that.

DB you should just get an ETEK and not the 06 Ego. You live in Exeter? As in Exeter, CA?

Sounds nice. I might end up getting my hands on one.

I foresaw his death last night; it came in the form of a projectile tank.

I honestly didn't expect much worse efficiency; QEV's just don't do much for ram and poppet driven markers (except boost the cycle speed).

Do QEVs even boost efficiency? I don't see how, because all they do is let the air out right there instead of sending it all the way back to the solenoid, right? Or something along those lines.

It depends, theoretically if the QEV's allow the forward and back portions of the ram to vent faster you could possibly lower the input pressure of the ram because of less resistance due to pressure; and you could gain efficiency that way. But the results of such a thing are going to be negligable, it likely wouldn't even result in an extra shot unless the marker has really restrictive air passageways to and from the solenoid.

Generally, the only markers that see gains in efficiency from the introduction of a QEV are ION's (to my knowledge anyway, there could be others); in which the addition of a QEV allows a much lower dwell, and thus higher efficiency at lower pressures.

E*TEK- 1,450 shots on a 68/45. That's about what I'm getting on my Ego. I guess efficiency hasn't changed to much.
