I've searched and oddly enough came up empty. Usually I can just search and someone has already made a thread and answered my question. And I posted it here because I'm not sure if it's an engine or drivrtrain vibration. So with that out of the way....
Last winter I installed a cobra engineering M122 swap on my 03 cobra amongst other things such as a steeda tri ax shifter and aem wide band.
I had a poor email tune update so I stayed out of the throttle.
High rpm (4k +) I get a bad vibration and I can feel it most in the shifter. It rattled like crazy until I shifted.
I believe it does it in neutral when revving also. It doesn't get worse with wheel speed, only with engine speed.
The things I've tried already:
Replaced clutch and flywheel (twice)
New frpp tob/fork/pilot bearing/pivot ball
Topped diff off and torqued pinion nut
U joints are tight.
Fresh synchromesh fluid
Checked that balancer and crank pulley are running straight, all pulleys turn nice and straight.
Idles normal and no CEL
I replaced the tri ax with a mgw
Do short throws really vibrate that much?
I'm at a loss here, the trans and motor mounts look good. I should note the car drives perfect at low rpm. I've put almost 700 miles on the new spec 3+ clutch. You can feel the vibration the most in the shifter handle but also in the pedals/floor boards.
I'm going to have 04 sleeper tune it, but I need this issue fixed first. Any insight or things to look for would be awesome.
