I think this should make an interesting discussion.
For those who are considering turbo first wait until your two year warranty is up. Harley cannot warranty the engine with a turbo added, not that the engine of a vrod will suffer. There are 3 turbos (actually one is a supercharger) that I know on the market, all cost the same and perform the same, 160 hp, but all look completely different. As far as I know they are all good products.
Firstly, Trask turbo made apparently in Arizona. Haven't heard any complaints about the product. It works, but personally I hate the pipes. Also there were some fitting problems, (can be overcome) on the mid control bikes, and reach extensions on the forward controls. Air pod points forward and sticks out from the right side and is quite noticeable. If you like it noticed then ok.
Second. There is the aerocharger, (boostisgood) that seems to fit the vrod like a glove. I had to look twice to see the install. This product fits any configuration of pipes and mid controls. That in itself interests me since I like the current pipes, but may eventually put on super trapps 2:2 in black. There is a inter-cooler that goes in the airbox. The point is I can use any exhaust set up I like.
Thirdly there is the the Sprintex supercharger, although not a turbo, performs the same HP increase. This is an Australian product that was brought out several years ago and had some problems. It was and apparently still is sold by V&H as well as some other company. It has returned to the market, new and improved, and the bugs have finally been worked out, at least I haven't heard any current problems. This unit fits entirely in the airbox and is completely hidden.
So all three options give you 160+ hp supposedly at the wheel. When I think about what would I do with that much HP, outside of racing. The basic bike does 135 or so (141 with tail wind) and modded will do up to 148-151. The speedo doesn't go up much higher. and adding another 40hp would push the bike into the 170-185 range.
The max that the limiter can be raised to is 10000 and I think safely as high as 10500 so that can possibly limit the max speed beyond 190
If money were no object, (the price is all the same basically) would I really want one of these and then again why?
