LP tippmann without lpk

Is it possible to have a lp 98 custom pro without installing the lpk. I ask this because from what I know all the lpk does is provide an extra space for the gas to go and therefore using a larger volume and less pressure. If I use a harder drive spring and an expansion chamber for extra room + a female stabilizer and a remote will I be able to get my gun operating at a lower pressure?

You could use an Expansion chamber that they sell for the Platinum 98c's + the female Stabilizer. You would still have to lighten the rear bolt, not just the recoil spring.

Right. You'll need to lighten the hammer as well as lighten the valve spring inside the valve while you filing out the air passages on it.

even then isn't the operating pressure only like 450-500psi? not much of a difference

Correct. The difference is minimal and the effort isnt worth it IMO. Running at 600psi with just a reg beats modifying the gun and spending money to run it at 500.

Oh, I was under the impression that it would run at about 300-350ish psi but I am still up for it. I like having projects to tinker with.

Not without doing some serious work to the valve.

I made an A-5 run at 650psi with a Male Stabilizer, JCS RVA, and a spring kit.

If you want to run at 300psi, then you are on the right track in needing some type of volume chamber to hold extra gas. Unfortunately, the only way that extra gas is going to get through the valve is if you make the air passages larger; the Tippmann LP valves have twice as wide of air passage that stock valves do.

Although, I noticed that just recently Tippmann started milling extra air channels in valve bodies. Here is what I mean: http://www.tippmannparts.com/index.c...&categoryID=13
I'm not sure when they switched, but my A-5 valve body had only 1 air channel on each side. The new one obviously has 2 per side. The LP valve had just a little more then this, the 2 channels were 1 big channel, there was no ridge seperating them. However, if your valve is this style then it should transfer enough air to run at 400psi or so.

Note, you will also have to get a lighter valve spring, and lighten your hammer. The whole point is to make the valve stay open longer, and release a larger volume of air at a lower pressure.

Oh, also, on the LP valve the pin is a larger diameter, I am not sure what exactly the point of that is or how it's supposed to affect blowback and such.
