This is Getting bad; If anybody thinks we should stop Let me know.

I'm trying to provide Sources + Experiances to back up my argument rather than pure hearsay.

Please check your Physics Friction - Wikipedia, the free encyclopedia
Friction is a direct relationship of Friction coefficient to pressure.

SO if you double mass (vector going down) you also double traction (vector left/ right).

Which will restrict the exhaust flow just as much as the y2k does.

What are you talking about?

Where do you get your info from?
2009 Nissan GT-R ECU Tune 1/4 mile trap speeds 0-60 -
Puts it at 11.1 which is in line with what I have seen.

First off; we are talking about turbo SHAFT engines in this thread; NOT Turbo Jet. Comparing the 2 is like comparing a fan boat to a prop boat; of course the fan boat. (Not a very good analogy; but you get the point.

Secondly you did notice that the F1 car was still ahead at wheels up; right?

Thirdly the F-16 is able to hold near full thrust standing still; find me a transmission that can handle that.

Where are you getting this information from?

first off the turbo Jet can get full thrust standing still; I can see no way to do that with a turbo shaft (where is all that energy going to go?)

There you go ignoring physics again.
Friction is not dependent on area. Here's the experiment I did in 5th grade
Friction, normal forces, contact forces: simple experiments from Physclips. Scroll down to "Dependence on area of the coefficient"

Second where do you get the 9.8 Second Y2k time? I can't find it anyplace.

"Typically" the limiting factor on high horsepower motorcycles is the ability to keep the front wheel on the ground. Don't believe me?
This is countered (somewhat) by a longer rear trailing arm (gives leverage a chance) but is still a factor and is one reason High Horsepower supras can beat turbo hyabusa's at highway speeds (the other is a motorcycles high drag coefficient)

If however you race to the .5 mile the turboshaft is going to get there in an additional 4.5 seconds even if it just maintains its 200+ MPH that it terminated the strip with.
I totally agree that the turbo shaft will eat a piston engine after 1/4 mile.
You also said it would be good on a road course. . . . . . How many straights are 1/2 mile?

The GTR will still be fighting and I'll say that it makes it to 200 mph in .5 mile and it makes it there linearly(it will take alot longer to achieve each mph so the average velocity will be biased towards 143).
a) What are you talking about?
b) GTR has top speed of 19x

Like I said above I have no doubt that a turbine will beat a piston past 1/4 mile.
