I would never do such a thing 
Be a bit obvious if my tec-9 was magically hitting 330fps mate
I still think my mp40 retains its spot as my highest fps blaster, havnt really played with the chrono for a while but I dare say it still holds the lead for the moment but I believe next would be my JG Works Aug A3 at up to 320fps
A bit longer and thicker than standard.
Very easy to install, and off we go…
Pretty good results so far…
I was using manual cycling, and green cats soaked for 2:10 as per brads recommendations.
First thing… it was noticeably harder to cycle by hand.
This is not surprising, but will place a higher load of batteries.
Second thing…some failure to load gels / double loading, which wasn’t happening previously.
I’ll try a few different batches of gels, and also try using the batteries, to see how they handle it…
215 fps is pretty much the standard fps out of these…highest was 248, lowest was 180 on a double feed.
Pretty impressive, they can get a solid 215 out of this barrel length / spring combo…
Makes the tec-9 look a little wheezy.
Mind you, this has solid metal gears (sic) and thick robust nylon construction around it.
I’ll see how it goes…if it struggles with the batteries, and double feeding/ failure to feed at times, it might be better to go back to standard…
But, 215 fps is better than a stock JM MP5-K …
And Kele’s standard punch around the 150-160 mark.
I was gonna mention that stiffer springs load the whole system, which is what can cause the feeding issues when the stock motor/battery struggle to cycle the slide fast enough to be able to get the gel feed rate consistent and reliable.
Moar power and an upgraded motor should definitely fix the issues! 
A couple of quick mags through, on the 11v battery…
It mostly fed quite well…but a bit of a drop in fps…??
Weird.
Manual cycling, you pull the slide back tight, as far as it goes…it ends to feed a bit better and the higher fps.
Batt cycling…quicker cycling, but some are lower fps.
Weird.
But, still early days, and I’ll brew up fresh gels/ for multiple runs of manual then battery , on the 2 different springs…
Why was that brand, of the wonderful lipos you were having so much fun with.?
Bwahahaha, forget that brand, I’m still back and forth with them regarding my issues and LOVELY review that I left for them!
They have fully refunded the money for the two I purchased, and are asking me nicely to remove my Review… but I just said send me some decent replacement batteries and I’ll think about it. 
Funny you mention that though, because look what the Courier JUST dropped off!
I spent the extra money and got the highly tested and recommended CNHL batteries in the meantime, and am about to go take the IR readings, give them a charge and head out for a run this afternoon. 
Yeah the old “lose FPS on full Auto” certainly is a pretty common thing with certain Gelblasters, so no surprises there, especially with an EBB Pistol. 
Single shot is more what I used my pistols for as a sidearm anyways, mainly due to the limited mag capacity more than worrying about the FPS!
Not unusual for electric pistols to hit harder on a lower voltage.
The 14.8v SKDs always hit about 10FPS lower on the full 14.8 voltage.
The funny thing is, its not full auto.
Semi only. Even with slow paced semi shots, a bit of a drop.
I wonder why manual gives slightly higher fps?
Anyway, 215 fps is still pretty impressive, for a pistol …
Must have something to do with the way manuals deliver their power. Same with the M97 manual shotguns… you can get 300FPS out of them and they still shoot the softer gels without destroying them. Seems to have a more gentle power delivery than an AEG with the same FPS.
From an engineering standpoint manuals shouldn’t be different… one uses manual force to lock back the cylinder under spring tension until you release it with the trigger, the other uses a motor to do the same until the sector gear releases it. Must have something to do with the way the gel engages in the t piece and the difference in dwell time before release that somehow increases latent energy in the spring 
I’ve got a KELe Glock 26 that easily hits over 200FPS, and a KELe Glock 17 that won’t go past 180 using the same spring and cylinder / plunger setup.
But your pistol shows different power output when you switch between manual and AEG.
Look at me being all Julius Sumner Miller…
