Are you fooling people around?
I thing, I can agree handpiece spec's. I have the Gr racing OZ TZ team version . And I have a OZ speed spec II. too. The Gr racing Oz Tz is a litte bit faster than the spec II. I tested both engine with %16 fuel and ospeed 1040 pipe. Same car gearing etc...
If the ozspeed engine specs on the website is right( 1.7 hp) I can say that the Gr racing engine is about 1,75 hp. I have with the Gr racing engine about 0,1-0,2 better lap times . Our local track is large european style track!
But this not a dyno test. But for me is the best test on the track.
