URD Mark II Stage 3

This is Gadget's X-Runner. It has the brand new URD Mark II Stage 3 C38-71 Rotrex Supercharger. 422 rwhp

The night runs were made on 91 pump with the rev limit set at 5800 rpms. The day run was 100 octane at 6200 rpms. On the last high speed run we were pulled over for speeding. A ticket was issued for 75 in a 65. The truck is a beast. It pulls very hard to 150 mph and feels surprising stable. The new MKII supercharger is amazing!

Update: Larger Rotrex Superchargers coming soon!

What's the top speed? And what's the time from 0-top speed?

[aswerty312]

@EQRoycerranMF At the time the top speed was 170mph. In the video it got uo to 150ish. Since then it has a different trans and gearing and more power, but I believe the top speed is much less. I have no idea what the time was.
