I don't know the record, but I've seen plenty of guys within the 450-475 rwhp range on a stock rearend. How long it will hold up is the next question.

To say that our diffs go because of too much HP, is like saying you buy playboy for the articles. :thepan:

A bit more info on the Diff bye bye ::

Driving my car home through my driveway notice spots - O I hope it is due to air conditioning being used, nope - parked the car 10 min later a puddle of diff fluid - O no - saw the diff being covered and dirty with oil. Took a deep breath and calm down called Luke / Bill at Lindsay and took the car in next morning - Bill cleaned it up and fixed the lead and took it for a test run came back and some more diff fluid - why he said?? cleaned and looked with more detail and saw a crack in the diff - Needs to be replaced - James from Lindsay hooked me up and now I have a new diff.

Question probably is what did I do - Was I flooring it, dropping into 2nd at high rpm, hard launch from dead stop - NO NONE OF THESE. Let's put it this way I am not having fun as much as I want to as everyother day something is going on and also my on-going F***ing Bucking problem that I have to resolve by taking it to the tune guy to see what is the problem.

Sorry guys this is the most I have typed in this forum - But I am frustrated a bit - I just want my baby back to its old self so I don't have to drive like a 80 year old.

For more tech info - Bill can chime in

Bucking = torque reversal. Torque reversal = bye, bye diff. Sorry to hear about your diff.

Your lucky you can take it to Lyndsay. Hopefully it was the bucking thing that cracked it. And hopefully a tuner can fix it. Again, your in an area that people can point you in the right direction to get that done.
When/if I get a Maggie, I'm planning on using the stock Magnuson tune for a while.
Good luck with it Mick.

In my experience, it's all about how you drive...

To a point that is. Once you get to enough HP, you're going to have some issues, something has to give.

It's torque that does it
And how hard you apply it

With maggie, so far so good
No dyno but probably 425 - 440 rwhp, similar torque

The TQ will def tear up the rear, but with moderation of the right foot, you can prolong the inevitable quite a while.
