View Full Version : Get more FPS?

09-11-2006, 10:41 AM
I have a Spyder with the old school(switches) E-frame, BL Torp, ACS bolt and rocket valve. At the field to day my FPS was only 190. After CRANKING the velocity adjuster and upping the pressure to about 500 I maxed at 240..... I am running a "green" main spring. What can I do to get more FPS without having the velo adjuster cranked down and lower pressure?

What kind of v/a are you running? Sounds like you are not getting enough air?!...

Did you drill out the V/A.... also did you Polish your striker... Did you adjust the Dwell on your rocket valve?..

Adjust your main spring/valve spring combo. Usually, I'd say to use a stiffer main spring, but with the Rocket Valve, you need to play with them some.

You prolly have the SRP on the Rocket valve turned too far in. Can you say.....repair kit? -
