how much hp is the stock open diff good til before it blows up and destroys everything? What do you guys think about quaifes?

 

Quaifes are one of the only full race parts that have a lifetime warrenty. Open diffs can run in a 500hp car, but they will break. It has a lot to do with driving style.

 

what else is needed other than the quaife to insstall in a 98 GSR tranny? how much should i expect for the install with the tranny outta the car? thanks

 

I broke two of the teeth in my stock diff when I just had some basic bolt ons. But I think that was due to the flywheel/clutch pieces that broke off and was flying around in my tranny. I have pics if you wanna see just click on my name and look for topics created.

 

I've seen a couple stock diffs take well over 300hp as long as you weld the diff pin in.

 

Like I said, we were putting well over 500hp on a stock diff. They will make a few passes no problem. They dont last long though. The teeth do break off. These were not welded at all...just factory open diffs.

 

I broke 3 stock diffs in my street integra when it was normally aspirated. The shock of a 6 puck clutch and slicks will kill them! Just get a quaife and be done with it.
