Bill paints the winning car at some NASCAR races, usually in Victory Lane, sometimes in one of the hospitality suites. He is a great guy and an architect by trade. I said I love the painting he did of me skiing. "That's not you, it's me!" lol. Just busting chops . . . . http://www.billpattersonart.com
Re BOP at Rolex. I spoke breifly with Kevin Estre before the Rolex race driving the #77 Wright Motorsports GT3R and I asked him a friendly question: "Why starting so far back in the grid?" He told me. "Its not good, the Porsche cars are at a severe disadvantage with the restrictors." I asked him if maybe the IMSA officials were taking everything into account including fuel economy and range. He said "no, its not enough to make a difference". "Sorry, the outlook is not good, but I will do my best and we'll see."
After that conversation, I lowered my expectations for the GTD Porsches, and it appears Kevin was indeed correct. The Rolex 24 is such a long, hard, gruling, (and expensive) race - dishearting to know you have little chance.

Reason: added pic
BoP: As of 8 FEB, IMSA enlarged the GT3R's inlet restrictors from 33 to 34mm and added 3 Ltrs of fuel capacity.

Also, I would assume 3L of fuel would be equivalent to approximately 1 extra lap. Considering how off the pace the car was at Daytona I wouldn’t think that would make much of a difference.
Hopefully someone smarter than me can chime in here and explain it to us…

I thought exactly the same, minimal overall increase at best, so I am probably more lost than you are. Help?

Your math is wrong. Going from 33mm to 34mm is a 6.16% increase in size. The area of a 33mm circle is 855.3mm² the area of a 34mm circle is 908mm².

33 x 1.03 = 34 (a 3 % increase).
His math is correct. His unit of measure (area vs. circumference) is the difference, but his math is correct.
33mm x/+ 3% increase in circumference is 34mm.

Let's not be stupid here. We are not talking about the difference between the numbers 33 and 34. We are talking about the difference between a 33mm restrictor and 34mm restrictor. Mike said:
"it is only a 3% increase in restrictor size"
It's not. It's a 6.16% increase in restrictor size. So yes, his math is wrong.
Sorry to get a little off topic but was thinking about attending Sebring this year on Friday and wondering how the garage access is compared to the ROAR which was an awesome experience!
