The lap times were the same, but you are also talking about a car that once you pulled out on the track you didn't lift as compared to one you had to. While I preferred the old track, it did race much larger than it was.

That being said and more to the point of the original post, i'm surprised that more people didn't contact Mr. Tobias when going the D2 route, seems like he has an entire bolt in/proven engine package there. I enjoy watching the Speedstr videos online.
