    Many thanks for posting - some great stats there. I wonder whether you are throwing down a gauntlett for other owners to have a play with a Racelogic box....?

    Look forward to comparing the differences with 100 Octane fuel.

    rolling starts from 60+, not from a stop (although those would be fun numbers to see with the 100 octane... :) )

    Bill, every Enzo-related thread that you start really needs a picture of your Enzo. :)

    And what's up with you being Rossa-subscribed and not having an avatar...? Show everyone that Enzo...!

    Unless the ECU is designed to pull timing with 91, the car shouldn't be any quicker with 100. Unless the octane needs to be at least 93. Meaning if it's 93 or 100 it wouldn't make any difference. Thats how 99.9% of modern cars ECU's work.

    While I generally agree with you in Bahrain we ran P 4/5 on 101 unleaded race fuel and it seemed to run very well. I also realize this isn't a scientific observation.

    The Owner's Manual says 95 R.O, whatever that translates into US (R+M)/2. When I add 10 gallons of 100 octane and then fill the tank, the car feels noticeably faster, especially over 7,000 RPM. So the ECU may be optimizing from the knock sensor output.

    Have you tried the runs not in race mode? It would be interesting to see what happens when the car shifts itself.

    Hmm... now you got me thinking about by avatar. My engineering side says a GPS time vs. velocity graph might be good.

    Same Enzo in the Circle of Excellence at Bella Italia in San Diego on April 4.

    Hmm, I didn't know the cars shifts itself! I gotta try that.

    Hey Bill,

    How do the Enzo times compare with the CGT times?

    Thanks, this thread is much better.

    And Jim's right, in 'normal' mode, the Enzo will shift at redline instead of bouncing you off of the limiter. I can't imagine, though, that it would be quicker that way than in race mode.

    They are close. The fastest 60 to 130 I can get with the CGT is 7.7 seconds with 91 octane (see below) vs 7.3 with the Enzo. That's with a 2-3 and 3-4 shift. If I start in 3rd its slower (unlike the Enzo) because the CGT engine is smaller and doesn't have the same low-end power as the Enzo. But they are both identical with a 2-3 and 3-4 shift.

    Over 150 or so, the Enzo pulls noticeably because of more HP and better aerodynamics at high speed. 0-186 mph in the Enzo is about 24 seconds and about 32 seconds in the CGT.

    Of course this is all kind of theoretical because on the road and track, the two cars will seem nearly identical. But, the sounds and feelings in the Enzo under full acceleration are more stimulating for me and the passenger than the CGT and the broader and higher torque in the Enzo make it more likely to spin the wheels in 2nd and sometimes 3rd.

    Note the higher speeds at the shift points in the CGT. The Enzo redlines at 8,000 and the CGT at 8,400.

    Yes. Almost the same as the 2.9 seconds for the Veyron... with 2 shifts at 62 and 92.

    If you'll excuse some pretty basic questions from a n00b at this graphs...

    The red line is speed, that's pretty straight forward, and I think the line that starts highest on the Y axis at zero is 'ride height', correct? That leaves the last line to be longitudinal accel (which is the 'g into your seat', right?).

    So the faster you go, the more downforce, and the lower the height goes. Is the big drop in long accel (around 3.8-4 sec) the gear change?

    I'm interested in how this Racelogic box measures height.
    Thanks!

    Almost correct. Height is absolute height above sea level. This is measured by triangulating among several GPS satellites. The height change in the Enzo's suspension is much too small to see on this scale. You're seeing the height change in the road. This should be as small as possible so gravity does not help the acceleration numbers.

    The drop in accel in during the gear change.

    Thanks, Bill. The height being road height makes much more sense, but I was excitedly hoping this was some new advancement in downforce/suspension measurement ;)

    That would explain it more, Euro 95 is like USA 89. So therefore as long as you run 93 or higher premium you should be good to go.

    91 octane in such a thoroughbred??!! I would never run less than 93+ octane in such as high compression, high HP engine! Actually more like pure 100 octane considering the value of that engine the low miles it's likely to be driven.

    You can't always get 93+ believe it or not in some areas....

    Now, this is a cool thread.

    I assume conditions were dry, sunny, etc. What was the outside temp. I have never tested an Enzo this way, but rumor has it that in cool weather the car is slightly faster--maybe 0.1 to 100 mph, but it is measurable. (I know race cars notice this difference.)

    I have never been in a car where it mattered--either the car didn't change or I was just too bad a driver to notice.
