I will have to make a run for black fittings gotta go anyway so no problem.
fyi Infraredline, 4th gear and 158 mph with a 3.82 LNF is 8200 rpm. You got a 4.05? just off 9,000 rpm. Use 5th gear; I have a 4.45 its really short, i am at 8k just to squeeze not even the ton and a half in 5th gear.
so the stories of 158 mph at 7500 in fourth spoil your good name just a little.
These cars like Japetr here and your Infraredline and finally Windypeg's bluenose are just fine machines. Enjoy them and remember they dont need exaggeration...

Interesting, standard gear tire calculator puts 4th (7800) at 162 on lnf wheels and tires oem
However redline wheels being 17" puts 4th (7800) at 155
Edit: scrolled up and infras running pokey wheels and tires idk anymore hah

3.48 1.76 1.18 0.89 0.70 those are the MU3 ratios ( F35) the LNF is 3.82; the LSJ is 4.05.
I will go into the detail of tire sizing and wheel revs per mile, but it is all such a pita. I verify my runs by tachometer readings and GPS and they correspond to the chart ( I have a 4.45 chart and a 3.82 chart is just a formated excel spreadsheet. The histograms developed with the dyno sheets are very interesting.
Japetr your tire should be 829 wheel revs per mile. do the math and tell me what you get.

I judged that speed based off of rpm, our gearing, and my 235/45/17 tire size. 7500 rpms in 4th shows up as 156.7mph. The speedo was just hanging in no mans land. On a slightly taller tire last year at the track I was trapping 119mph in 3rd gear with my limiter set to 7600 and never reaching it. Blue's car at 7900-8k this past weekend was doing 126mph in 3rd.
My main point was that I could get to redline in 4th this spring without running out of fuel.
