At this point, I hadn't tested it on the track. I tested it in a wide open parking lot. The same parking lot where I did my testing with my Sirio. From my observations, there was NO, or virtually no drop off in top end. If there was, it wasn't noticable. When I first ran my Sirio at full speed, I could CLEARLY see the difference between it and my TR! But not with the R-Spec.

But once you get pass the 'rough times' just getting the thing started, and you start leaning it out, you'll see the speed it can produce. And like I said, I don't even think I got all the speed mine had to offer! The hottest I got mine yesterday was about 190 degrees...I think it has more to give...

I can't guarantee that it will skunk a moded Sirio or X12 on a 200ft straight, but standard engine against standard engine, I think it could hold its own.
