Robert Pothorcki aka “Mr. Syclone”, gives us an inside view from the cockpit of his truck, currently the fastest V6 AWD Syclone (8.7@162mph) in the world. While he doesn’t comment on his speed, we all know to well he’s going into triple digits as he tears through the streets of Sweden as he does a “test-n-tune” for his 2016 race season.

Robert’s path to 8s hasn’t been an easy one. While we can’t exactly say how many variation of motor setups he has been through, we can say that the carnage of parts and videos of breakages he’s posted shows that he is pushing the boundaries of V6 power coupled with AWD. We look forward to seeing what 2016 brings for Robert and wish him the best of luck in topping his own 8.7 second 1/4 mile record!

* While ISTR loves racing videos, please be aware that racing or testing your vehicles on public roads is dangerous not only to yourself, but to others. Oh, and it’s typically illegal. We aren’t here to tell you how to live your life, but we can tell you that you should use every precaution possible when driving your trucks….and that includes doing it at the proper facilities set up for racing and testing.  Keep it boosted!
