Weird. I don't get that at all. How fast is your idle set?
Around 900 RPM I think. It does disappear when I blip the throttle at idle.

As for the "damper", it's one of these. I welded on some extra tubing and tapped it to fit 7/16" rod ends to work with the STS brackets. Forgive the flux core ugliness. Not pictured is the left side of the arrangement. The rod has a "plunger", which is basically a washer fastened to the rod and is holding another donut captive against the end of the cylinder. The right rod end is threaded directly into the cylinder cap. It's a shock absorber that uses bushings instead of fluid, basically:
I'm running a lightened flat flywheel at 17lbs I believe.
On my bench is another T5, need to tear it down, install the billet countershaft retainer and Fox body input, then see if it rattles in the same install setup as the one in the car. I seriously wonder if there's some flex in the stock countershaft retainer, allowing for some of this rattle.
go way back in TB time and look for posts by odinthewanderer regarding this issue, he was fighting it back in 2010. He had a very well thought out car with a brand new $2500 hopped up t5z from modern driveline. He went through and through and through that transmission chasing the rattle, I think ultimately he reached the conclusion that this is life with a lightened up buzzy b230.
It bugged him enough I bought that car, and I moved his entire drivetrain into my car which probably make 300hp more than his did. It's still going strong. I fixed a lot of my own vibrations with rear end changes, but sure there's still some decel noise. It really doesn't bother me, and I feel like I'm in a shrinking club of people who really enjoy their t5. Now my engine mount NVH, that does bug me.
Just offering this because a) it's certainly not a new revelation and there's been some pretty detailed discussion in the past b) I've seen smart and talented people try and fail to un-**** box their volvo and get pretty frustrated by it c) cars can be a lot more fun if you're able to broaden your range of acceptance of their inherent shortcomings.
Update to my setup but I was finally able to shoehorn in the big effn slip yoke into my setup the other day and I gotta say this made the biggest improvement to date.
No more coast down resonance. No vibration during hard acceleration. All noise that I have now is engine related which as a fearless leader once said "it is what it is."
I was able to adjust my trans such that I did not need to cut the floor to get this think to slide in. However the drive shaft cannot be removed without lowering the transmission crossmember from the body.
I was pretty blown away by the improvement and I currently have all of my carpet and foam out of the car so there were "noises" but once I install sound insulation to the floor the car it should be a little quieter.
I think it may be time for the mission accomplished banner!
cool! do you have a pic of your final setup?
This was pretty much my experience with that big damper, too. Glad it helped.

Thanks for the pics. It is encouraging to know that you didn?t need to cut the tunnel...this may be added to my winter project list.
