I emailed Shandy before I started my project. The person that wrote back said they had done a 700 with a GT12 but it had too much lag for his taste. He reccomended a 5-10hp shot of N2O to help spool the turbo up, or to get a Hitatchi HT10 something or other from an older Kawasaki street bike.
Looking at the pics, I can see the actual turbo header is very short and that they mount the turbo closer to the underside of the fuel tank, as opposed to the oil tank like I made my header. The downpipe\turbine discharge pipe if you perfer was press bent, as opposed to mandrel bent. The charge pipe is also press bent.
Reading the contents of their kit, it lists a pressurized air box. I would like to see what that looks like. There is no filter that I can see on the turbo in the pics. Im sure when they have time, they will put more pics up.
I dont think your gonna find anyone else offer a turbo kit and install it for $2500. They specify shipping so that makes me think they are not mass producing these kits, and dont have an inhouse quad to jig the kit off of.
