You doing the Tx shootout? Ready for Nevada next year? I may run the Silver State...depends...if the storms in the Baja area turn away..it's tuna killing time. If not we will run the 218 road out of Ely.

That's insane, but what tires out there can actually allow these runs to be done smoothly?

 

dot R compounds i imagine, or race slicks on a really sunny day

 

Yep. Heck, even a Hennessy Viper took BFG Drag Radials to 220 mph in a recent 0-200 mph shooutout.

 

Roland,
Texas Mile this year, Silver State next year with a few local vipers.
I will be in touch (sorry for O.T., but this guy is the high speed guy)

Joe,

I like your thinking, but the supercars do have traction problems in second,
this is one of the reasons why 60-130 does a good job of measuring power to the
ground. 100-300 kph is even better but of course harder to do.

Yeah, but do you have traction problems at 20mph in 2nd? How much rpms is your car turning at that speed? I would think it would be less than 3,000 rpms. Would you still lose traction accelerating from there?

I know in my Mustang I would lose traction in 2nd, even if I started from a dead stop in second. It would break loose once the engine reached around 5,000 rpms while accelerating. After upgrading the rear tires to 315/35/17 I didn't have that problem anymore, though. I would think AWD would make it even less likely you would have traction problems.

 

yes, on high boost and my regular street tires, depending on road conditions,
I encounter traction problems (in first and second). 10 second cars generally have
traction problems. My rears are 315/25/19 Michelin PS2's. If you rode or drove
a PE700 996TT (or equivalent GT700, etc.) you would understand where I am coming from.
From a roll, myself and my "GT2 buddy" have yet to lose any street rolls versus the
local "10 second street cars" and one of the reasons is we have "better" traction but
not great traction, depending on factors listed above.

So even at low rpms in 2nd gear (say around 2,500 rpms) you lose traction? That is crazy power. You aren't even making any real boost at that level.

 

Also remember some higher hp cars have converted to RWD.

 

That is something I don't quite understand either. Do you get some advantage by switching to RWD other than less drivetrain loss? Don't you lose traction and handling by doing that?

 

Driving through Texas

 

Uh-oh. That's a dangerous quesion right there. (inside joke)

Less weight, less drivetrain loss, and better handling if the car is setup correctly. Just think of the primary advantages a GT2 has over an AWD TT, and those, in essence, are the main reasons for the conversion.

 

No, I am not losing traction at 2500 RPMs (dont think I said that).
torque curves are different on low and high boost, but either way you do it; as it
rises above 4000 RPM the tires start to scream...

Scott,
Can you explain why a GT2 needs more HP to reach 235mph than a 996 awd tt? I don't understand, I would think that a gt2 would require less hp
