thats a huge difference from the 90 PSI recorded earlier....I dont think a different cam would cause that....It sounds like the guy with 90 PSI's checked his compression with the valves partly open.....or something....I know that impossible to do really....so what gives....Originally posted by Redy@Jun 3 2004, 08:29 AM
I have 140 psi .... but I have stock cam.
I had no idea.Originally posted by lukester720@Jun 3 2004, 09:31 AM
Due to the bigger cam (the HRC opposed to stock) the pressure in the cylinder would be reduced due to the valves opening further for longer. Redy didn't say if he had an aftermarket pipe or not, but KGB has an lrd which would flow better than stock which would alleviate some pressure also.

NoNo...first you disable it....
You know by increasing the clearance till it has no effect on the rocker arm....that way at any RPM it will show your compression...
Or am I wrong?
