60-130mph VBox - 650 v 12C v 488

Make of this what you will.

Hi all. Just thought I'd share, FWIW...

A few qualifiers/disclaimers, as there will always be debate anyway:

  • Times may NOT be directly comparable to what you're seeing in the US. our conditions (temps, humidity, especially FUEL) are specific to the Philippines. times are however, comparable to each other
  • All three cars are showroom stock. 12C has factory power upgrade
  • Cars run on different dates. 12C and 488 ran with cooler temps (approx 80F; 650S ran at closer to 90F)
  • Cars ran on the same stretch of road with the same take-off point and the same take-off protocol (floor pedal at around 40mph)
  • 12C was well run in. 488 and 650S both had <300miles on the clock
  • 12C and 488 driven by same person (forum member on here)
  • 650 had a full tank of gas but no passenger. 488 did not have a full tank but had a 140 lb passenger. i can't remember conditions for the 12C

Our sense is that the 488 could definitely improve, given the motor is still tight. Same for the 650, as the Ferrari was run closer to Christmas, and my car ran at the height of summer.

Interesting too that the Ferrari did not feel fast, but obviously has the numbers to back it up. 458's and Speciale's are significantly slower with our fuel. And I mean close to two whole seconds slower (verified with three different cars using same testing protocol).



Again, numbers in the US or Europe may be different than these, given fuel and environmental conditions. Intent was simply to measure relative performance of the cars given our conditions.

Super interesting. Thanks for sharing. This jibes with other members and videos that the 'lowly' 12C still can take the new 488. Just shows how impressive the design was back in 2011.

6.94 - 12C
6.94 - 488
6.64 - 650S

we've VBox'd approx 150 individual cars over the last couple of years, all following the exact same protocol and location. It's become a small tradition of sorts. Quite nice when guys from different clubs, or even sometimes different tuners will come out, curious to run their cars and see where they stand in our little database.

We try to be as scientific as possible, but of course you can't avoid variance due to temps-- a car run in January will have an obvious advantage over a car run in April (height of our summer). But many people will "re-take" when conditions are ideal, so there's multiple attempts, also after a round of mods.

I wish I had a buck for every time someone shows up with their car after spending sh*tloads of money on mods... only to find very modest gains versus stock. and in some cases, their cars actually being slower! But all in good fun, and people have come to realize that dyno numbers don't always translate as much to real world performance as one would like to believe.

There are some interesting patterns too we've found from doing this so often. Certain makes and models simply do not live up to the performance hype you find in the press. Or at least to how said cars perform elsewhere. Worst offenders are the V10 M5's and 458's. We think it must be our fuel.

The 12C/650/488 are the only stock cars that have broken the 7-second barrier for us so far. Of course the tuned FGT's and GTR's are into the 5's, but we're talking stock cars here.

Interestingly, the Aventador and F12 haven't been able to break thru to the 7's yet... But there's an SV that still being run-in, and if any (stock) Lambo should do it, that should be the one...

What's crazy is my GTR does it in 3.5 secs.

What's especially crazy is AMS, T1, and UGR doing 60-130 mph in well under 3 seconds.

488 is very weird with performance.

It can only use it's max potential when using launch control(because that's the only situation it can shifts near 7800rpm)

when doing a rolling start, it can only shift at 7500rpm(limiter varies to 7500rpm), which significantly affect it's acceleration, and Ferrari needs to fix it.

you're right, just noticed this with the 488 loaner i had yesterday.

in Auto mode, it wouldn't shift anywhere near redline, and it would choose upshift points at WOT inconsistently. i assume this is the computers figuring out the optimum shift point, given existing conditions?

Have you got numbers for the 570S?

Let's keep this alive to compare tuned McLarens. This way we can see a trend in performance. I will have my stock car and prototype turbo kit with flash and then MoTeC to compare.
