How to measure horsepower

In a totally scientific measure of horsepower. Road and Track measured the horsepower of a few cars, with the chart below.

The light one was the Alfa 4C. The darker one was the Mustang GT. The thick, black, almost liquid one? Yup, the Hellcat!

So, the 4c has a lsd. It did leave two marks!

I always thought it was the number of stickers on the side

Stickers measure claimed horsepower, not whp. Claimed hp varies according to whether females are listening and whether faster cars are nearby.

depends on the tire too.......

I remember having a set of Dunlop D60A2... and I could light them up all day... and that was with a 112hp 4AGE

I thought that you just started by counting them? Keep in mind that factory power rating is off by quite a lot, kind of like American V8s from the sixties, it must be an insurance thing

Wait. Most of those aren't horses so they don't count.

In reply to iceracer: There is a conversion formula for mule-o-watts to horsepower, but it confusing, and I'm never off it's gross or net.

Sam Smith said it was BMW M3 vs Hellcat vs Mustang. FYI.

According to him (and he'd know, he was there): straight one is the Mustang, the darkest one is the BMW, the light one (with a gap for a shift!) is the Hellcat.

haha, NICE! I think mule-o-watts bring more torques to the party. I don't want to confuse things, but they often have a lower center of gravity.

Here’s the transfer function…

(actual horse power X verifiability X beer consumed X listener hotness) = claimed horse power

I'll have to smack my source then.
