The 100-200 is faster than the Veyron.

Must be lots of fun to pass a Veyron WOT.

I have to find one first.

There is something wrong with your run IMO (looking at your chart on 6speed) - your second gear change takes ~0.4 secs (so quite slow) and the Gs drop from ~0.6G to 028G........ this does not look correct in my experience, given a slowish 0.4s change the Gs would normaly go negative or nearly negative.
To maintain a 0.28G acceleration at 95mph for 0.4s would need a lot more than 0.6G just before the change.
Still looks like a 60-130 groundbreaker

I make nearly 800 ft lbs of torque to the wheels. That's probably why the G's come back so quickly.

TB993tt

It is not the Gs coming back quickly which I am reffering to.


The portion I have marked in pink is your gearchange where there is zero positive Gs from 3.3s to 3.7s since your engine is decoupled from your drive -the longitudinal acceleration line should dip into negative Gs here as the car is being slowed down by drag (areo and mechanical), instead it only dips to ~0.28G so still showing a nice push in the back - not possible

The blue circle shows the torque coming back online and shows it delivering a ~0.45G hit.

To make it easier to envisage think about the thump in the back you get when you let the clutch back out after changing gear - well your graph is showing that the "thump" only goes up by ~0.17G whereas in reality it should be the full 0.45G.
Something's amiss

Also, where are you testing that is 120ft below sea level

Maybe the underwater testing explains the "G,s " !!!!!!

Good to see the usual , non personal ,arguments back .

I've seen other speed/time graphs look like that. I think it's the smoothing function of the software that causes it.

10' above. As far as something "amiss" on the graph....whatever it is or was doesn't seem to negatively impact the real-life acceleration capability of my car. She moves quite well.

Have a good one.

Nice machine Scott. Now go find a Veyron to smoke!

Stummel

May I ask have much is a gallon of this 100 or even 117 octane stuff?

Anywhere from 5 - 9 bucks a gallon depending where you live.

I don't know your definition of "smoke" but unless you are only interested in short bursts the Veyron is in another league, especially 280 km/h and up. Drive one and report back.

I am far from an expert TB and I know you may have your PHD but how would a graph look
if you were spinning and creating G's and then you let off (albeit very quickly--speed shift),
and the tires stopped spinning temporarily and "hooked up" ?
Just a thought as I have an AX-22 and can barely get it out of the box let alone decipher the 800 graphs it gives me from one run...

Having had the chance of a lifetime to drive a Veyron last September I can honestly tell you that it is not the most exiciting car I have ever driven. However it is the most civilised and fantastically competent bit of kit that you could ever wish for. This is a car that you can drive at the plus side of 200 mph on twisty French motorways and the only thing you have to worry about is pointing the car in the direction you wish to travel and concentrating on where you wish to position the car. Believe you me it really is in a different league to anything else you will ever get the opportunity to drive.

Do we have any data for 993GT2 EVO II with ~600hp?

What should be the hp range for a full wing lightweight street 993 GT2 with 6.7s for 100-200kph?
