How big is your engine, really?

Lets all compare engines. Using your hp-per-liter and cylinder size measurements, you can scale your engine size up and down to see what it would be like with fewer or more cylinders. Follow the example I show after the break and share your results!

My Neon has a two liter I-4 putting out 132hp. This means that it makes 66hp/l and displaces 0.5l per cylinder. These are my base stats.

If I were to scale it to match different engine configurations, with the same cylinder size and hp/l rating, I get a:

1.5l I-3, 99hp

2.5l I-5, 165hp

3.0L I/V-6, 198hp

4.0L V-8, 264hp

How does your powerplant stack up against mine?

I'm actually pretty impressed with it, in V6 form it makes about the same power as GM's infamous Series II 3800 with 0.8 liters less displacement, and as a V8 it matches the contemporary Mustang GT with 0.6 liters less!

350Z w/ VQ35DE - 82HP/L; 0.583L/ cylinder

1.75L I3 - 143.5 hp

2.3L I4 - 191 hp

4.7L V8 - 382 hp

5.8L V10 - 478 hp

7L V12 - 573 hp

Not too bad, just wish I had the VQ35HR motor that made about 307 hp.

I have a 197hp and 2.0L of displacement.

So here goes:

1.5 I3: 148hp
2.5 I5: 246hp
3.0 I6: 295hp
4.0 V8: 394hp

Impressive, and more proof that Honda is dropping the ball not making their bigger engines based off of the K Series. Just add DI and include both types of VTEC for the perfect blend of MPG and Speed.

I have a 2.0l spitting 175 hp. That's 87.5hp/l. Based on that I would have

1.5 I3, 131 hp

2.5l I5, 218 hp.

3.0 I/V6, 262 hp

4.0 V8, 350 hp.

If it were to be 5.2l, like my Dakota, it would have 455 goddamn horses! All this out of a 25 year old four banger.

1.4L inline 3= 153 hp
1.9L V4= 204 hp
3.7L V8= 400.3 hp
5.6L W12= 1285.67 hp

I got 5.5L V8, 388hp.

Split in a half and you got 2.75 i4 producing 194hp. Not bad.

Stack two of these with glue and you got 11L V16 producing 776hp.

And this is NA.

I always felt like the Mk5 and Mk6 should have had a HO version of the I5 for the GTI and GLI. Something a little bit more reminiscent of the VR6. I'm thinkin like 210hp and a 7k redline.

2.4L flat 6, 80HP:

...though the turbo version made 150HP at 15 PSI. So it scaled pretty well really.

I have a 1.6L I-4 with 115hp. that means 71.875hp/l and 0.4l per cylinder.

So.. that would give me, oh let's say a 4.8L V12 with 345hp.

Not THAT good, but it's 1997 Mitsubishi so I think it's decent enough.

Not that a 4.8L V12 would ever fit, but a 2.4L V6 would, and I bet 172.5hp would be quite fun in that car.

113.125 bhp per litre
0.4l per cylinder

Parallel Twin (extra Britishness) 800cc with 90hp
Triple: 1200cc with 135hp
Inline 6: 2.4L (scales close to standard BMW engine size) with 270hp. Closest comparable engine from BMW would be the N52B30 in my Z4 (and that's half a litre larger)
V8: 3.2L (Italian like displacement!) with 362hp
V10: 4.0L with 452hp (a BMW S85 is a litre larger and make only an extra 55hp. Compressors do help)
V12: 4.8L with 543bhp

Exactly! The 2.5 had so many good qualities. The only reason it fell behind is because VW refused to update it. Full aluminum construction, DI, a 6th gear. So many things that could have been done to modernize the setup and make the engine a winner in the marketplace. It's already competitive, but putting some time and money in it would have made it the top segment choice.

5.7 V8 - 265hp

Our '89 Wrangler makes 110hp out of 4.2 liters. That means it would make a 5.6 liter V8 with 147hp, or an 8.4 V12 with 220hp. It's a stroker, though, so the torque figures would be through the roof.

2.3L in my Mazdaspeed6 puts out 270 hp (more with the mods it has).

That's 117 hp/l, which would equate to 716 hp if it were the same size as the 6.1L LSx in my '71 Nova (which has roughly 500hp). Turbochargers are God's true gift to man.
