I have a bone stock 2006 xkr and I wondering, ballpark, about how much power my engine can handle.

 

Am still trying to find it...

 

I would think you would start having issues anything above 700bhp, pretty expensive getting there though

 

I was thinking along the lines of a kenne bell. I havnt looked into it but when I had my 04 svt cobra, I heard power gains were drastic. And I've heard a kenne bell fits onto this xkr of mine. So that sounds like a winner.

 

This a where avos needs to make another entrance

He has done the twin screw set up using a kenne bell, not cheap, but pheonominal power, look at his signature and there's a link to all the info

Good luck

 

Here is the link with more info on the kenne bell 2.6LH twin-screw kit:
