..... and, as always, here's the math behind it:
With your current 5-speed, per the gear calculator we made before at 160mph you would be turning 5100-5200rpm in 5th, as you saw in your video (+/- the smaller tire size and any growth of diameter at speed). However, based on your dyno power curve you are making just over 400bhp at that point. To get to peak power at 6400rpm in 5th you would need to be running right on 200mph down a very long hill.
Alternatively, with the GT500 transmission here is where 5th would be:
So, at 2km you would be turning around 6200-6300rpm in 5th and making the extra 50bhp to get to the mid 160mph range, with peak power coming at around 167mph.
The difference between the two, it's like you're crossing the finish line on 7 cylinders vs. where you could be with a shorter 5th.

Ok, I shopped. Now, Red IS going back, to Daytona at the end of this month. After this weekend's exercise I hope Red doesn't get run over at Daytona while his 5th gear is growing hair. He used to pull a lot longer in 4th with the stock setup and then 5th was nearly useless, too high to pull like on a race track. Maybe the overall outcome is the same or better but it sure does feel like he's stuck needing a gear between 4th and 5th. One of Superman's suggestions was to get somebody to bust open the tranny and exchange the .6 5th gear cog for a .8, but then he wouldn't cruise as calmly on the interstate. So it is what it is.
RE shopping I saw a piece on TV where Tim Allen toured us through his car collection. He got to the Ford GT and said he wanted one badly because the challenge was getting considered "qualified" to buy one. Forget the fortune they cost, you have to be a special someone to even buy a new one, even a used one if I paid attention correctly.Patrick & Tammy

Meanwhile, to complete the post-race round-up, due to a big oiling down on Saturday afternoon, racing was called about 6pm and everyone who was in the staging lanes was told they could keep their place in lines (numbers were taken) and that racing would start at 6.30am on Sunday. As I was parked out at the start line I did that, and the racing did actually get going on time on Sunday AM. Weather was cool, with a slight headwind and a few sprinkles from time to time - enough to see on the cars, but not on the track, except for a hold for a couple of minutes when it got damp mid-track.
On that basis things ran smoothly and like a regular Saturday in terms of racing; numbers were low so once the five staging lanes had cleared down, we could just loop back straight to the start line, and so I managed 4 runs by 9.30am when I stopped to pack up. Meanwhile, Jake finished his rookie passes in Lon's Neon, and Lon took over to see just what the new intake could do.

Originally posted by pdub View PostA huge meet. The Strupps have done something right to attract a participant base, they are here. My guess is a large percentage of the folks are rookies. Here's a shot from the drivers' meeting yesterday evening, all that would fit in the shot. This is a very very small fraction of the crowd. More cars on trailers were coming in as I was leaving yesterday afternoon.
