Yea, it will shake out. All I have is dyno data so far. Maybe at the March TWS national I'll run a back to back run on the test day and see the on track difference. I guess I could do it at MSRH next week to if Ed remembers to bring his 37mm plate.
See you TWS.

I know running back to back on the same day would yield better comparisons but I only have a 1 car trailer. Weather was very similar in November.
Bottom line both cars are close in lap times at MSRH so it will be intersting to see the effects on the 99's lap time under the new NASA rules. My guess is a loss of 0.30 per lap at MSRH, probably less at faster tracks.
Wouldn't it be more of a time loss at faster tracks where HP is more of a factor than the quantity of turns/mile at MSRH? I was thinking the NASA rules would really hurt the 99 at places like TMS, RA, the longer tracks
So this race the 99s were in the 2010 rules trim?
The 37mm plate will hurt the '99 at TWS/TMS, not so nearly as much at MSRH. Horse power isn't the big factor at MSRH--the 60 lbs knocked off the '99 might actually get it close to equal lap time with the 2450 weight with big restrictor. Overall though, I am certainly of the opinion that they still need to take some measurable weight off the '99 in NASA trim to get it right--but their approach of closing the weight and hp+tq gap is just too logical The NASA 94-97 needs to get slowed down too--probably smaller plate as opposed to more weight. )
Yes, they raced this past weekend at MSRH in old trim (big plate, big weight)...

Only problem with dropping more weight off the 99 is that some of us larger individuals won't be able to make the NASA 99 weight. I can strip about 30 lbs out of the car, but that would leave me about 37lbs heavy with one gallon of gas. I could loose 37 lbs but then I would make weight in my 1.6 and it would potentially be the better car at the faster tracks. Not to mention I would have to give up eating for 2 months.
