I have your data. It's the driver.
I'm not going to try and compare my 1.6 to any NB car out there this weekend because I couldn't find a good setup on my car for the whole weekend. The car was super loose in the back end and I could not get it settled down. So all my breaking points were way off.
Ralph did put a box in my car and compared it to a couple of the top 10 guys and the power and speed seems about the same down the whole back straight. But again I was hitting the brakes way sooner to try and get the car settled before the corner.
From the data and from me having to hit the brakes sooner than I liked I can see I lost at least a second to a second-and-a-half every lap because of that. So that is why I cannot honestly tell you how I feel about the comparison of the NA to the NB.
I can only blame myself and my car setup for being two seconds off. But I will say if I can get a good setup on the car I see no problem knocking 1.5sec off my lap times which would have put me in the top15. I can't prove that right at the moment but it's just my guess from looking at the data
