I've always run the poly mount on TKO swaps, no issues...I'd ask Inland Empire what there balance speed is when they balance a shaft,...suprisingly most shops only balance up to 3500 RPM,....you want a shop that can balance up to 10,000 RPM shaft speed, for a TKO application Mike

Guess I would really call it a vibration maybe more of a harmonic thing. Starts about 3000 rpms in all gears or neutral even. But from out side the car things all seem pretty smooth. I want to get the drive shaft checked. But I have been putting it off because I have to pull that exhaust apart to get the shaft out. And getting the exhaust apart is hell and then some 1971 Hemi Cuda 2005 SRT-10 Regular Cab Flame Red. 12.771 @ 109.67<---TIME SLIP--Video

That would be 8200 rpm engine speed in 6th and there is no way your drive shaft will ever see 10000 rpm in any other gear (or in 6th for that matter).

Actually drive shaft speed is dictated by gear ratio and tire size. Lets see 10,000 rpm with a 4:10 gear and my F60-15's would be 188 MPH and 6400 rpm on the engine. (this is baced on a .64 OD ) Yes the pucker factor would be HIGH Last edited by Mopar_Mudder; 10/29/13 05:56 PM. 1971 Hemi Cuda 2005 SRT-10 Regular Cab Flame Red. 12.771 @ 109.67<---TIME SLIP--Video

Did the TKO600 come with a .5 OD ratio? I see a .82 and a .64, no .50 What road speed would you be doing at 5000 engine rpm in OD? or 6400 engine rpm?

My numbers in above post are based on a .64 OD I know what you are saying that you will never see that speed. But it would stand to reason that faster you spin the shaft the more acuraccy you would see in balancing it. 1971 Hemi Cuda 2005 SRT-10 Regular Cab Flame Red. 12.771 @ 109.67<---TIME SLIP--Video

It did seem to change the vibration some. It is not as high of pitch/frequency now, a little bit lower. I don't know that it help it or is just masking it so you don't feel it as much. Also in the past I have noticed that the vibration get worse as the further you drive and get stuff warmed up more. It was only 45 degs last night so I am sure things didn't get warmed up as much, but I was able to go 80 with out feeling like I was pushing it too hard. I think I am going to work on exhaust next. I notice that a drone in the exhaust actually comes in about the same time as this vibration, wonder if the two could be related some how? Have to try an figure a way to get a resinator in the exaust, not much room to do it.... Also I checked the drive shaft for run out while I was at. Rear = .014 Middle = .0075 Front = .009 1971 Hemi Cuda 2005 SRT-10 Regular Cab Flame Red. 12.771 @ 109.67<---TIME SLIP--Video

Hopefully you can find one that's honest about it otherwise you'll pay for another balance job & that wont fix the problem cuz it's balanced OK right now but people have reported on occaision in severe cases that it took several different shops till one of em got it right. Holler how it goes. live every 24 hour block of time like it's your last day on earth
