Bucking while cruising and percieved rev-happy behavior
Hey guys. I have a problem with my 2002 C5 Z06
Relevant mods:
Cam
3.90 rear
headers
intake
mcleod rxt and steel flywheel
The car while driving at a constant speed will buck between road force and engine force. I can feel the shifter clank a bit, like part of the engagement of the driveline is loose. I don't know how to explain it in words exactly, and the car is currently apart in my garage and I can't take a video. It seems to sound like the bucking you would expect at low rpms in first in a parking lot from a cammed car, but this happens at all cruising speeds. It's most noticeable when going up hill and only a slight amount of throttle is applied to that threshold between acceleration and deceleration.
Second question is that the rev and clutch characteristics of this car seem to be very much like an aluminum flywheel. Requires lots of gas and clutch to get in gear.
Would these two problems be related to each other? Would they be solved by replacing hydraulics?
Car is apart right now. Torque tube seems fine, clutch seems fine, I'm not touching the diff or trans but they don't seem damaged.
What I'm doing now:
Installing tilton master cylinder, new slave cylinder, and remote bleeder.
I'll be changing both diff and transmission fluid as well.
I have a pilot bearing but I'm not sure whether it's worth the time and effort to remove the flywheel to change.
