I have never heard of anyone adding a weld in the combustion chamber to raise compression. Thats just goofy.

You could also just throw some JB weld on top of the piston to raise the compression, if you were a dumbass.

I have also heard that you can wrap the rotor in electrical tape(the more you wrap, the higher the compression!!) then cut slits out so the apex seals can come through... this also will raise the compression, if your a dumbass.
