BDHG940 Posted March 16, 2011 Report Share Posted March 16, 2011 Getting ready to do the rear suspension and rebuild the 8.8 in my notch. Its going to be making pretty good power so I want to make sure I just do it once. I do plan on driving it on the streets so I dont want to set it up just full blown for the track. Those that have built setups for similar applications and high hp, what do you recommend? Quote Link to comment Share on other sites More sharing options...
schmuckingham Posted March 16, 2011 Report Share Posted March 16, 2011 Everyone ones opinions are going to be different, but what HP are you planning on making exactly? Quote Link to comment Share on other sites More sharing options...
Stimmel1647545512 Posted March 16, 2011 Report Share Posted March 16, 2011 chad do with 31 slpine stuff it can be had at a reasonable price throw a good auburn diff in it if money permitting and if need be throw a rear end girdle on it I think they look cool more than they are functional but oh well Quote Link to comment Share on other sites More sharing options...
TurboRust Posted March 16, 2011 Report Share Posted March 16, 2011 I did a 31 spline cobra diff with carbon fiber clutches, mosers, frpp gears, jegs diff girdle, in the mach1 and everyone saw how well it held up under all the abuse at the track days over a hundred passes on slicks, all 1.5-1.6 60' short times on 450 whp Quote Link to comment Share on other sites More sharing options...
DKilbourne Posted March 16, 2011 Report Share Posted March 16, 2011 I did a 31 spline cobra diff with carbon fiber clutches, mosers, frpp gears, jegs diff girdle, in the mach1 and everyone saw how well it held up under all the abuse at the track days over a hundred passes on slicks, all 1.5-1.6 60' short times on 450 whp I will second the cobra diff with carbon clutches, moser 31-spline axles, and frpp gears. I have a ford racing girdle, but that came with the rear end. It doesn't have to be crazy to hold up to decent power levels. Quote Link to comment Share on other sites More sharing options...
BDHG940 Posted March 16, 2011 Author Report Share Posted March 16, 2011 It will be min of 650-700 wheel and I was looking at some of the detriot rear end products. I really just dont want a locker as I will drive it some on the streets still and dont want anything too annoying. I have 31 spline axles already so just need to figure out what diff I want to run so I can get it bought. Quote Link to comment Share on other sites More sharing options...
Patterson Posted March 16, 2011 Report Share Posted March 16, 2011 They have a soft or "quiet" series as well for the Detroit set ups. Quote Link to comment Share on other sites More sharing options...
BDHG940 Posted March 16, 2011 Author Report Share Posted March 16, 2011 I was looking at the detroit truetrac but didnt know if it would be good for the power Ill be making. I couldnt find much info on higher hp cars using it Quote Link to comment Share on other sites More sharing options...
DKilbourne Posted March 16, 2011 Report Share Posted March 16, 2011 This is going to be an auto car isn't it? The Ford 31-spline carrier will hold up and isn't $5-600. Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted March 16, 2011 Report Share Posted March 16, 2011 I ran a 31 spline detroit locker, moser axles, and jegs brand gears Quote Link to comment Share on other sites More sharing options...
BDHG940 Posted March 17, 2011 Author Report Share Posted March 17, 2011 Yea its going to be a mod motor/c4 setup/and a little boost Quote Link to comment Share on other sites More sharing options...
NTHER91 Posted March 21, 2011 Report Share Posted March 21, 2011 most high hp cars jus bite it and go spool the tru trac wont hold long with those power levels auburn is a great one or the more expensive detroit ones Quote Link to comment Share on other sites More sharing options...
hpfiend Posted March 24, 2011 Report Share Posted March 24, 2011 I had eaton 31 spline LSD, mosers, TA girdle, FRPP gears in my coupe well- the rearend did make a "binding" noise/feel in parking maneuvers but was very stout... fwiw my dad's c6 did the exact same thing and they put a revised fluid in it at the dealership under some tsb and it silenced it. FWIW I think the cobra diff is made by eaton. Quote Link to comment Share on other sites More sharing options...
BDHG940 Posted March 25, 2011 Author Report Share Posted March 25, 2011 I found a pretty good deal on the 31 spline cobra diff, if that falls through Im just going with the detroit locker Quote Link to comment Share on other sites More sharing options...
