Horsepuckies!
First off the wing and valkyrie are quite a bit different. I've owned both.
Don't let the size fool you. The wing has 85 hp and weighs in at about 900 lbs. Pretty darn good HP/Weight ratio if you ask me.
I don't know what the stock valkyrie does HP wise, but mine just dyno tuned and has 126 HP.
I have an photo of the bike just after we bought it at
http://www.weg.net/~vince/vince.jpgNow for the techie stuff. The engine is a 1520cc flat 6 water cooled. Stuffing one in a VW would be a waste of money. If you can find a wrecked one the engine is going to cost at least three grand. You can build a kick ass type IV for that kind of money.
The valk engine is a torque monster, it is not a high RPM engine. I can have my wife and I both on the bike pulling a 300 lb trailer and can still pull away from most bikes. I have the revlimiter on mine set for 6000 RPM.
Visit
http://www.valkyrieriders.com and check out the link called the Nickel Trick. It is something you will never be able to do with a VW engine. I know mine wont.
You know I have to be a bit strange. I have a water cooled 6 cyl bike with over 100 HP and a 4 cyl air cooled car with 40 hp.
