Age : Displacement Ratio

Whatcha got? Prizes awarded for highest and lowest scores! A friend of mine asked me this question today, as I’m now approaching the dawn of my 5th decade of life. Right now, my ratio is 9.75:1 (I’m 39 today and my car is a 4.0), and I made the joke that I should try to keep it below 10 for as long as I can - about time for that stroker...? So, OPPO, what’s your ratio? For those of you with multiple motors in your possession, keep it to one! If TwoWheelsGood, please add an asterisk.

I love 1.6 so the ratio is only getting higher.

15.625

5.3 for the pair.

Is a high ratio a good thing or a bad thing?

At 25 with a 1.8 so my ratio is 13.9:1. Now I just need to get me one of these to lower my ratio:

13.75, give or take a bit. I’m 38.5 and have a 2.8L. This should be interesting as I expect older members to generally have larger displacements and older cars.

33 / 2.5L = 13.2

33 / 4.2L = 7.86

If you want to get fancy and do a weighted average, it’s 9.85.

Biggest engine: ~28.80 years (at 365.25 days per year) / 1.839 l = 15.66 years per liter

Smallest engine, actual displacement: ~28.80 years / 1.798 l = 16.02 years per liter

Smallest engine, effective displacement (Atkinson cycle, 13:1 expansion, 8:1 effective compression): ~28.80 years / ((1.798 l / 13) * 8) = 31.87 years per liter

Haha - 38 was a good year. I did that wrong, anyway. I thought you were talking about two different engines and stupidly thought cc instead of cubic inches.

17, even though I have an engine with above-average displacement (on this continent) while still being a millennial. Despite the 5 cars I own 17 is the best score I get. Granted, with two of them. The others are 21.25, 24.28 and 26.15.

Hahaha - YES! Two very good scores. I think you’ve got an extra zero in there, though! 560* still blows everyone else out of the water (until the old guy with a motorized scooter shows up).

Several month ago, I had a ratio of 2.98:1, with the 350 the PO swapped in my truck (found out it wasn’t actually a 305 two days before I sold it).

davesaddiction @ opposite-lock.com > TheTurbochargedSquirrel
01/25/2017 at 12:30

I wonder what the accepted multiple for a turbocharger should be. Maybe 1.4x displacement? That’d give you an 8.9.

01/25/2017 at 12:35

Ha, you got me, thought it seemed high!

Yes, as far as road legal motorized vehicles go it doesn’t get much less than 50cc so it going to have to be someone older than me :)

TheTurbochargedSquirrel > davesaddiction @ opposite-lock.com
01/25/2017 at 12:40

Doesn’t matter to me, mines N/A.

1.4 is actually the standard displacement modifier for turbos for Rally America and the like.

bhtooefr > davesaddiction @ opposite-lock.com
01/25/2017 at 12:58

I’d go with relative boost in bar, plus 1 bar, as the modifier.

Bought my e30 at 22 so I was at 8.8:1 but that’s now at 10.2:1. WRX isn’t helping at 13:1.

I prefer horsepower to age as a ratio because there are some massive displacement engines that make very little actual power (Muricah!). That comes out to 10.3:1 for the Subie.

davesaddiction @ opposite-lock.com > TheTurbochargedSquirrel
01/25/2017 at 13:04

Ah, screen name so deceiving!

1.4 seems a good average.

davesaddiction @ opposite-lock.com > DasWauto
01/25/2017 at 13:11

Horsepower would give more “fair” ratios, for turbocharged & electric motors, but displacement sure netted some interesting ones!

I’m at like 11.5:1 HP/years with my M3.

Sub-2.0 is even more nuts. I have a buddy who is 16 and fixing up a 500 cube Caddy with help from his uncle. His ratio is 1.95:1.
