Eski ama guzel bir yazi
Cycleword dergisinin 2008 yilinda profesyonel surucuyle yaptigi testler ile Texas Mile da 206mph ceyrek mildede 10.8@143mph kosan bir Porsche GT2 nin pbox surelerinin karsilastirmasi.
Bu cycleworld dergisinin surelerini daha oncede paylasmistim belki hatirlayan arkadaslar olabilir.
150mph sonrasi motorlarin yavasladigini o zamanda yazmistim ama simdi arabayla kiyaslayinca dahada belirgin.Zaten kiyaslamayi yapan Scott da ayni seyden bahsediyor alttaki yazinin temelinde.

CycleWorld did a 0-180 mph test of a bunch of bikes back in 2008. They used professional riders for the test and measured the acceleration of the bikes at various intervals from 0-180 mph, as well as terminal velocity. The quickest bike overall in the test by a large margin was the ZX-10R. The slowest was an R1. The Hayabusa and GSXR 1000 fell in-between the two.
Let's look at the numbers compared to a 730 rwhp GT2 that went 206 in the TX mile and has also run a 10.8 @ 143 in the 1/4 mile.
First, the GT2 (I've extracted the times from his TX Mile Performance Box data). The GT2 driver is a good driver. Not a pro, but a good driver nonetheless:
60-100 - 2.55
60-150 - 8.53
100-150 - 5.97
100-180 - 11.64
150-180 - 5.67
Now, extrapolating the data in the graph, the bikes ran the following roll-on times:
R1:
60-100 - 2.33
60-150 - 7.71
100-150 - 5.38
100-180 - 15.88
150-180 - 10.50
GSXR 1000:
60-100 - 2.30
60-150 - 7.28
100-150 - 4.98
100-180 - 13.43
150-180 - 8.45
Hayabusa:
60-100 - 2.41
60-150 - 7.60
100-150 - 5.19
100-180 - 13.26
150-180 - 8.07
ZX-10R
60-100 - 2.38
60-150 - 7.16
100-150 - 4.78
100-180 - 11.99
150-180 - 7.21
Notice that from 100-180 and 150-180, the GT2 is faster than all of the bikes. From 60-100 and 100-150, the GT2 is very close to a couple of the bikes. From 60-150, the bikes really dominate against this particular car. But at higher speeds, the bikes really start to slow down.
I think this data helps to explain why your average rider (not a guy that necessarily sucks, but someone that isn't a pro or a very experienced amateur), may find themselves being tied or yanked by a fast car. Especially if they are going well into triple digits, or they make one mistake (short-shifted, started in wrong gear, etc..)
Remember, this GT2 is only making 730 rwhp. Let's add 100 rwhp to that. My old 996TT at 830 rwhp (and 200 lbs heavier) went 60-150 in 7.60 and 100-150 in 4.48. That puts it smack dab near a ZX-10R.
Of course, some cars are faster than others, just like some bikes are faster than others. But considering all of the data, as well as the videos that are out there, I think it's safe to say that any car making 700+ whp is an honest threat to the average rider on the average liter bike, from a roll.
