PDI spring help

[Steven]

Hey everyone, been putting together an upgrade list for a TM VSR-10 Build, and would like to know what PDI spring will get me:

1) 450 FPS
2) 500 FPS

Any help would be awesome, their site is very confusing.

1) vsr 280

2) vsr 360

There wont be exactly 450 FPS, but the PDI 200% spring will raise the FPS to a consistent 445-455 FPS depending on the cylinder and spring guide.

For 495-510 FPS, I believe a PDI 310% spring will do the job, but again it depends on the cylinder and spring guide.

But these estimates are based on a New England climate, I would ask a gun doc nearby, as air pressures/climate differ, and you may achieve different results

That's what I thought, but underneath PDI's description says that those ratings are with a 6.01 and .29 SMG's.

Is this wrong?

EDIT: Would posting my planned set-up help you guys?

Mmm... their website is very choppy for an English translation, I couldn't tell

Found under the VSR-10 spring table for springs 200-360. "Test has done with VSR-10 Pro Sniper, Precision Cylinder Set HD, RAVEN01+ Inner Barrel 430 & 0.29gBB(Maruzen GM).Please note ; That's a just sample.,so may be changed depend on condisions."

Also, this is what my set-up will be:


TM VSR -
Precision Cylinder SET/ VC -
V-trigger –
4 Bull 10mm Barrel Spacers-
Bull Barrel Base-
“P” Bull Barrel-
Bull Barrel Cap-
PDI 6.01 430mm 10mm outer-

Not complete, but that might help you.
