Hope you have a good gearbox casing.... That kind of power will surly destroy a standard V2 gearbox...

crap so basically i need to figure out what the hell he put in there then. any suggestions as to what would would work best?

Depends on what you want it to shoot and what your local field limits are (most around here are 400fps w/ 0.20g bbs).

A pretty generic answer is to stick a Modify M110 spring in it. That'll put you in the mid to high 300's.

Hammer13 · October 29th, 2008, 19:20

im already in the high 300's, but one of the guys I play with uses a 170 and his stays acc to 400. I'll look into it farther, Thanks for the help

Systema M120.
It should set you to about 400-410.

A bit on the limit, but with the right parts, you can get it to 398ish.

You can also use a JG stock spring with a TM piston head. The spacer in the piston makes for the drop of power. That is what I am using. 398 fps on the spot.

gvanzeggelaar · October 29th, 2008, 19:32

your fps also depends on barrel length. There has to be a long enough barrel to get the maximum power out of a spring. With an m110 my m14 shoots about 380. With the same spring my MP5 shoots about 330

That's a 170%, which is very different from an M170.

Hammer13 · October 30th, 2008, 16:37

BAH! so a 170 spring is differnet from an m170? goddamn I hate springs pretty sure im just gunna leave my gun the way it is for now lol, I dun wanna break my first gun!

m102404 · October 30th, 2008, 16:50

There's a lot of info on springs...but the short version is..

some springs are labeled as %...where 100% is ~290fps w/ 0.20 (aka "stock", TM, m90)
---so, approximately, a 110% spring is 290 + (10% of 290) 29fps = ~320fps

some springs are labeled in Meters/Second...where a M90 is roughly "Stock" = 90m/s * 3.3 ft/m = 297fps
---so, a M110 spring is 110m/s * 3.3ft/s = 363fps

170% = 493fps
M170 = 561fps

The gotcha is that it's all approximate and dependent on quality/precision of your parts and assembly. The other gotcha is that some spring makes are just guestimates and may vary wildly between batches.

Think I got that all right....

Well... the entire purpose of this thread was to point out differences in these springs...

Hammer13 · October 30th, 2008, 19:26

ok I think I got it now, Thanks for the help here guys, and Damage, yes in from bcac and I dont know everyones name atm lol but i think it was linden, i unno, i also dont know wtf he was talking about when he was talking with me and gem, I asked what was in it and all i heard was numbers and letters mixed in with a few words. :?

Skladfin · October 30th, 2008, 19:32

linden's the guy that has insane AEGs that fire fireballs.

his PTW is off the charts, that one was semi only because it shot so hard.

damage · October 30th, 2008, 19:39

I am betting what you heard is PDI 170%.
