blazeone Posted July 6, 2010 Report Share Posted July 6, 2010 When changing to a one piece alumimun shaft do you need both front and back loops or just one end if so, which end? Thanks! Link to comment Share on other sites More sharing options...
muvover Posted July 7, 2010 Report Share Posted July 7, 2010 Just the front the rear will hit the shaft when the car is on a kift at full drop and also hit the top of the loop before the bump stops. Link to comment Share on other sites More sharing options...
MichaelP Posted July 7, 2010 Report Share Posted July 7, 2010 I did one BMR loop in front as well with one piece drive shaft. Link to comment Share on other sites More sharing options...

bpmurr Posted July 7, 2010 Report Share Posted July 7, 2010 I have the dynotech. How is it? Do you notice any additional noise or vibration? Link to comment Share on other sites More sharing options...
MichaelP Posted July 7, 2010 Report Share Posted July 7, 2010 How is it? Do you notice any additional noise or vibration? Yes and Yes. I have not spoke to the shop that installed but they told me there would be some different "noises"... Im thinking that Ford had our cars pretty well setup from the factory for a "cushy" ride... Now that I have added UCA/LCA, panhard bar and driveshaft car is going to perform better for me at dragstrip and track but be less streetable....which I'm fine with.. If I see you at Cecil in November with SSOTN you can ride in car with me to listen... M. Link to comment Share on other sites More sharing options...

I don't understand how a lighter weight driveshaft with less rotational mass could vibrate more or make more noise than the heavier iron driveshaft. I plan on upgrading to a Dynotech on my '11 when they become available but don't want loops or plan on jacking my HP over 700 (probably 650 long term) or tracking it. Do I need driveshaft loops?

Well, the loop for me is for the dragstrip. You would not need that if your car is not tracked. Maybe I have the squeaky rear differential thing happening but we added friction modifier.. I'm pretty sure it is the driveshaft... M. Link to comment Share on other sites More sharing options...

Its not the rotational mass, its switching from a two piece to a one piece that causes vibrations. Even though a poorly made aluminum driveshaft can cause all kids of headaches.

Yes, just talked to my mod guy and he said the same thing.. It does not bother me while driving... I just wanted to make sure everything was "ok"... M.
