we live in a such a positive feedback world....
I am very impressed with the engine Chris - very clean.
The idea - very good.
Your tenacity and execution - great - 10x better than mine ever will be.....but...(oh oh...here it goes...)

Unfortunately I'm going to have to say it....I'm not one to lurk in the shadows whispering, but....
I don't like the styling....it ain't MB styling....needs some curves ipod stylist panache...
there you go...I said it....I - personally, think its ugly.
Maybe NW's can flash it up or dumb it down and give you a royalty. ATM it looks like a bolt on farm piece.
Sorry - but my 2c.
But - it would work under my OEM MB Engine cover to possibly protect it.

Beautiful engine all the same, and love all your work.
