Das folgende zum Dana 44 habe ich mal von "Cheynut" kopiert:
I have never seen any published torque ratings for either the Dana 36 or Dana 44. What I do know is that all automatic tranny Corvettes came with the Dana 36 in all years and gear ratios varied from 2.59 to 3.31. The Dana 44 came with all manual tranny cars except for the '84's and they had factory gear ratios from 3.07 to 3.54. The ratios depended on the year of manufacture and the option (ZR-1, etc.). The Dana 44 can be fitted with 4.10 gears too.
The Dana 36 has a 7.875" ring gear, and the Dana 44 has 8.5". Both have aluminum cases and covers and all C4 diffs are POSI. I am not convinced that ring gear size alone is the ultimate indicator of differential strength. However, the iron 9" Ford is most likely quite a bit stronger than the Dana 44. But how strong does it need to be for a street car with street tires?
The Corvette Dana 44 is sometimes referred to as the "Dana Super 44". It has a special gearset that does not fit in other Dana 44 units (like the jeeps and trucks), so don't go by the other differential's torue ratings. It's also the same differential used in the Dodge Vipers which now put out 505 HP. The Calloway Twin Turbo Corvettes used the Dana 44 and put out 560 ft-lb of torque. I'm not aware of any problems with it.
So, the bottom line is that I believe if you're not running huge slicks, both the Dana 36 and the Dana 44 can take a fair amount of abuse. Obviously the Dana 44 is stronger, but I don't know how to quantify it.
So, jetzt wissen wir immer noch nicht das verträgliche Drehmoment der Dana 44 Hinterachse, haben aber gelernt, dass es eine Menge packen kann...
@454 BIG: Paßt das Tremec 5 bzw. 6 Gang als Schaltgetriebe als Drop in für ein TH350 bzw. 400?
