I just don't see it. But, I suppose only time will tell.
+1!! Oh, and here is the link the the Hamman 560bhp V10, it’s based on a regular 3 series coupe with an M3 kit etc…, etc…, and does not appear to have the M-diff that if installed am almost certain would allow this car, especially with the huge 325s in the rear, to reach 0-60 below 4.0 seconds. http://www.rsportscars.com/bmw/2007-bmw-hamann-thunder/
If they do rework the stock internals, for huge gains, it will be well over 15k.
On stock internals I am expecting 525 rwhp. I mentioned 600 wheel as to what the internals were capable of handling, I don't think any supercharged E46 M3 hit this number, the turbo cars did.
Either way, it is going to be fun to see what happens.
