Get your mind out of the gutter, it stands for "Fleet Average Horsepower Per Cylinder." Basically, take the total estimated horsepower of your fleet, and divide by the number of cylinders. Our driveway has realistically 580 horsepower coming out of 22 cylinders. That gives me a FAHP-PC of 26.36 horsepower per cylinder. What's your FAHP-PC?
How many cylinders are in my turboWankelmotor?

Counting shards of apex seals? Billions.

Three combustion chambers per rotor, for an equivalent of six cylinders in a two-rotor.
46.5 here.
365 hp v6.
201 hp flat 6.
225 hp 5 cyl.
791 hp. Divide 17 cyl.
Lest see, v8-450hp. V8-150hp. Boxer 4-150hp. In line 4-125hp. Briggs 1-14.5 Honda 1-13. So, 900ish divided by 26 is....
Hell, my math skills suck. But it's definitely not a big enough number.
Mazdeuce and AussieMg should be fun.
OK, I'll play the game. 250+170+170 = 590 HP. 590HP /12 cylinders = 49.16 FAHP-PC. If I drop out the wife's car it goes up to 52.2
547 hp / 14 cyl = 39.07.
Golf TDI (183hp/4 cyl) w/ tune, 1.8L Miata (133hp/4cyl), 128i (230hp/6cyl).
WRX (265hp/4cyl) + Outback (173hp/4cyl) = 54.75 FAHP-PC
If I still had the C4 Vette the average would drop under 40. 
UGGGHH at the house and not in storage.
53 cylinders I think counting the one little one in the electric.
2900 or so HP I think give or take 100. ~53 I think which is low. We do Torque and I think I have most of you beat, or just the ones in the garage.
130 hp in the Integra B18A1 138 hp in the Sonic 1.8
33.5 hp/cyl.
Waiting for someone with a Tesla P90D and a BMW i8 to swing by.
So, I have ten cylinders and 366 HP. That's 36.6 FAHP-PC.
So let's see.
425 hp V8, 332 hp V6, and a 265 hp V6. So 1022/20=51.1
My wife needs to pick up the slack and get some more hp out of her xterra.
Lets look at the current fleet:
1977 Chevette: Rated at 63hp-not all there-call it 55; 4cyl
1979 Chevette: rated at 70hp-not all there-call it 60; 4cyl
1983 Chevette: rated at 65hp; 4cyl
1987 Chevette : Engine missing; 4cyl
1989 G20 Van: Engine missing; 8cyl
1990 Miata: 116hp; 4cyl
1992 Saab 900 16v: 140hp; 4cyl
1992 Chevy S10 Pickup (2.8L 5 speed): rated 125hp (clutch slips)-call it 115; 6cyl
14.5 hp/cylinder
And here I thought I might actually get into negative numbers!
210+95+6 is 311 between 11 cylinders is... 28.27 hp/ cylinder. Yea, I sure wish the Miata had that by itself.
I have 20 cylinders at the house for a total of 675 horsepower, also known as 33.75 hp/cylinder.
But I've got 67.5 hp/L!
160+132+237+200(?) = 729.
4+4+6(2 rotor)+8 = 22.
33.14 hp/cylinder
450+300+370+255 = 1375
8 (audi) + 8 (duramax) + 4 (Miata) + 6 (FD) = 26
Average 52.88
The FD is bringing my average down!
Interesting.
Volvo is at maybe 180hp from four cylinders.
VW#1 is at 0hp from five cylinders.
VW#2 is at 0hp from four cylinders.
VW#3 is at 0hp from five cylinders.
RX-7 is at maybe 250hp from zero cylinders.
430 divided by 18 is roughly 24hp/cylinder, with three non-running cars.
Now if you want to talk about how much power they'd be making if they all RAN...
Volvo: 180 from 4
VW#1: 115 from 5
VW#2: 90 (I think?) from 4
VW#3: 300 from 5
RX-7: 250 from 0
935 from 18 is 52hp/cylinder.
If they all ran...

That's not the way it works... that's not the way any of this works.
If you accept that a 4 stroke piston engine requires two complete revolutions to cycle its entire swept volume, then you could only apply two of those rotor faces per rotor. Which is why a 1.15l 12A moves air like a 2.3l four-stroke piston engine, a 1.3l 13B moves air like a 2.6l, a 1l 10A moves air like a 2 liter...
The inherent inefficiencies mean that most sanctioning bodies use a 1.7 or 1.8 equalization factor. In reality, a 13B can get smoked by a 2-liter four built to equal specs. (The trick is, you'd need to dump 5 figures into your average 2 liter to get it up to the point where a 13B starts out from)
323-6 (2015 Camaro)
305-6 (2016 Impala)
300-8 (1992 C4 Corvette)
230-4 (1986 Merkur XR4ti @ 21psi)
1158/24
48.25 HP/Cyl
Damn C4 Vette dropping me out of the 50s...wait...I forgot the Merkur...turbocharging bringing me back up a bit...just wish I had numbers @ 30psi...
In reply to Junkyard_Dog:
I think you have a Chevette problem...
Well, if they all ran:
Subaru 165hp/4cyl
Miata 190hp/4cyl
Montero 175hp/6cyl
Saab 160hp/4cyl
MG 50hp/4cyl
Grom 8hp/1cyl
CT90 5hp/1cyl
37.65 at best, much lower in reality.
6 @ 218 E24, 6 @ 210 SC, 6 @ 210 Liberty, 8 @ 260 Mustang, 8 @ 250 P71, 8 @ 230 F350, 4 @ 110 Samurai, 5 @ 220 Colorado, 8 @ 210 SanFord and 2 rotors or 6 @ 150 Abomination.
65 Cylinders, 39.7 liters, 2068 horsepower.
52.09 HP/liter
31.81 HP/Cylinder
I forgot the boats.
8 @ 260 Sea Ray, 3 @ 90 Key West, 2 @ 50 Jet boat.
That brings me up to 78 cylinders, 47.0 liters, 2468 horsepower.
52.51 HP/liter
31.64 HP/cylinder
