It's all relative. What do you call "lightly breathed?" I would call that a cold air intake and maybe a tune. In which case those combined aren't getting the new mustang into low 12's by a long shot.

Cold air intake, full exhaust and tune....maybe. But decent money and not what I would call "lightly breathed."

but back to my 2012...

I lost by half a car at 85 mph (not safe to keep going)- before I put headers, probably a 12.90-13.00 car at 111-112 at best (street tires). It was close and I had a long rev range, but it just did not have the power in that configuration. Over 100 mp[h would have turned my way. Definitely have more top end with the improved exhaust now. Anyways- we are talking 300 cubic inches in a car that weighs 100 lbs more- a lot of the mustang pop comes from the VVT 4 cam variable timing and the deep trans gearing. 1st gear is 3.66:1 ratio. fifth is 1:1. First gear is 13:1 ratio with 3:55 rear gears. Cheapest 12 second car I've ever owned. My friend was laughing his *** off too.

2012 was only 100 lbs lighter for an identically equipped car.

The 2015 is slower. But the best MT got out of the 2014 was a 0-60 of 4.3 and a 1/4 mile of 12.7. That's a best time with an above average driver and certainly not indicative of what the cars are averaging.

And again, it depends on the car. Some are simply better than others. That's not out of the range of a stock ZR1 though.


The funny thing is, we're arguing about a car that was designed in the late 80's against cars designed and built 30 years later...The new ones should be faster.
