View Full Version : Will Replacing Spring Increase more than 245 fps?

I was playing paintball today and my E99 was firing at 245 fps. I guess that is the correct word. The fellow said if I replaced the spring that controls the velocity I could get it up to 285 fps. I saw on ebay a lot of different springs, has anyone replaced theirs and can recommend a spring?
Also would replacing the bolt increase the velocity? I was really surprised that this really old tippmann 98 I bought for $20 was firing at 325 and they had to turn it down. I thought for sure the spyder would fire further. Is 245 what it should firing?

Thanks.

Yes get a spring kit to help fine tune your FPS.

As springs get older and if the weather was cold they act differently.

if you get a spring kit with the right tension, it should work. i dont think that replacing the bolt will do anything to the velocity but dont quote me on that.

This may sound silly but you sound like a noob so is your velocity adjuster (screw on the back of the gun) turned in all the way?

most bolts will have a different airflow than the stock bolt. taking the venturi (star piece) out of the inside should increase fps by a few feet.

Yea I had the velocity screw screwed all the down. Will give the spring a shot. Does 245 sound about right for E99? Or does anyone know the highest it can go?

usually they shouldnt have a problem hitting 300+. all the older spyders have pretty much the same internals, and ive gotten my imagine to about 320...

try taking it apart and do a complete cleaning of everything inside the body, and check for any debris that may have restricted airflow.

is your spring guide still in there?

The rubber part that goes in the middle of the spring? Yes is there and the striker bumper or what ever that rubber ring is called.
I might try pollishing the bolt and striker to up it up some. I read here that is a good thing to do.
