Found this on YouTube and had to share. This is C63S with only a RENNtech ECU tune vs. a Ferrari 458 Italia with a Capristo Exhaust.

I'll let the video speak for itself... but a stock 458 Italia traps around ~125 MPH in the 1/4 mile.

I own both cars... 2015 C63S and 2012 Ferrari 458.

I have 1/4 mile videos from both cars....same day, same track.

The C63S is faster by .1 / .2

Very nice! What did your 458 trap in the 1/4 mile that day?

I noticed you're running catless downpipes and air filters on top of the Eurocharged tune. Still very impressive that these cars can creep away from a 458 with just the tune alone on pump gas!

Wonder why this is; a tune should only give a slight hp advantage, but the 458 has nearly 900 pounds weight advantage... and probably aero too.

Torque and Turbo Boost in Addition to more HP and rolling start helps

Yes, can someone please explain?

Gearing, Boost, Shifting, temperature outside.. Lots of factors

The 458 trapped 123-124mph

My 458 has 22's on it too. LOL

Impressive indeed -- thanks for sharing.

The standard 458 weighs about ~600lbs less than the C63S (has a curb weight of around 3350 lbs), but makes 450 WHP and only 316 WTQ:



It makes sense that at rolling speeds, a tuned C63S with 517 WHP and 565 WTQ is more than enough to compensate for the weight with an extra 67 WHP and 249 WTQ!



Torque is a great thing

Makes sense. Wasn't too familiar with the 458, so my Google search pulled up 3050 as the weight.

Torque, it's all about the torque

I think a lot of people who are not used to high torque powered vehicles especially forced induction ones that produce all their torque from low revs underestimate how much quicker they are, ie. if traction is not an issue

Nice run there.

Speaking of torque, would like to see 488 vs c63s having 250! Ft pounds more than 458....

No chance against a 488 GTB. Those are running somewhere around 10.5 @ 135 MPH stock. Amazing what a pair of turbos (and $250k) can do 😋

Thought the front page would dig this one too...

The Italians are VERY deceiving... All Italian manufacturers quote DRY weight as their vehicle weight. Add a solid 300 pounds to all the Italian numbers you read to get a more accurate number. Mclaren started doing the same thing too in order to compare apples to apples versus the Italians.
