Been working on my '05 TWIN TURBO pn and off for a while.
Have not kept up with the latest news.
What is out the for a HIGH horsepower car. *900 ++HP*

 

I dont know what power level it will hold but roush has a 1pc drive shaft that is 399 but it requires you change the pinion flange. So in the 500 or category.

From what ive seen however is that most 1pc kits out there handle in the 1000hp category, but I dont know if its whp or crank, after the trans power loss is 100+ hp on a 1000+ hp car. Honestly though, if you have the cash to build up a 900+hp monster then you probably should have the cash to have a custom driveshaft built to your specs. Remember the higher the HP the more one off parts you will need.

 

Steeda doesn't list the max for their shaft on the web site but you might call them and find out. I have one and it's a good piece , of course I don't have the HP your looking for ...

Check out Shaftmasters (www.shaftmasters.com) - they just came out with their new 3.5" shaft that is a "bolt in" replacement (no adapter etc)

 

Just to add to this. Axle Exchange builds Steeda's driveshafts. I have never heard of a problem with them either. When it comes time, the Axle Exchange driveshaft is going on my car.
