I am wondering how a S2K (stock or tuned) dyno compares to a 2l B engine.
Show me some comparo if U have both results. thanks

 

I HOPE THE B SERIES TAKES THE F!!! I dont think Stock S2K is anything that special, i have a good amount of work on my B16 and in comparison from riding in both, my B series feels MUCH stronger....So 2.0L B should Kick A$$

 

if only the f20c received the same aftermarket support as the b series....

 

IMO, it is not that simple on a 2.0 B to beat the S2K.

Waiting for dyno pics...

When you say you rode in both, are these two cars of equal weight?

 

Hold on, I'll post 'em.

EDIT:

Here you go.



Solid line is our 85x89 stock sleeve B20/VTEC CRX, dotted is a customer's '02 S2000 with 2.5" exhaust, modfied stock intake, tuned with VAFC.

For a stock motor, the f20c is pretty strong.

But it's not even close in this comparison.

D, Thanks for the plots.

 

Thanks Derek!
Do U have more?

 

well thats obvious! the B series puts down to the wheel what the f20 makes to the crank!

 

I have a ton of N/A 1.8 liters to compare it against.

Anyone want to see the difference between an F20C and an F22C?

SURE

If you can can you post one comparing a B18 to a F20

I think my old b18 setup vs that f20 would be close, post it up son!

 

id like to see the f20 vs f22 as well

 

Here's BMo Tuning's PR3/Pro1+/GSR build vs AP1 F20C S2000:



And the F22C vs. F20C graph. Both cars have same mods, except the AP2 has cold-air intake:

Wow, I never realized how much of a stronger engine the F22 was.

 

D-rob can you overlay your 85x89 setup vs your K20 setup...

I noticed this in the first AP1 graph too, this F20c seems kinda weak no? Considering the F20c and F22c are rated the same bhp, shouldn't the whp be similar or at least not have a 20whp difference? Perhaps something characteristic of the dyno that makes them look different?

 

s2k is my next car
Got a quote today on the CR versions.. Looks nice and i hear they loveeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee the jigga juice
of course i'll stay all motor with it , if i get it.

So honda rated them at the same bhp, that doesn't mean a damn thing.

Ford rated their 03/04 cobras at 390bhp and they dyno 380whp......

Honda bumped the compression by .1 and added 200cc to the engine, its going to make more power even if the head/header/exhaust/induction components remain the exact same.

The dyno at innovative reads kinda low anyway, the graphs look ok to me. The one with the bigger displacement and more compression made more power everywhere, like it should.

I don't doubt what you're saying is true, just seems like a massive difference. Perhaps the bolt-on mods benefit the F22c more than they do the F20c? I'd be curious to see what the F20c and F22c dyno stock.

It is a pretty massive difference I will give you that, it kinda surprised me too lol.

I'm not into s2000s enough to know if honda bothered to upgrade the header/exhaust/head/cams/intake on the ap2 to accomodate the 2.2 liter better so I can't say if bolt ons did the larger engine more good than the 2.0.


Drob tell those two s2000 owners that hondatech said to return their cars to bone stock and re dyno on the same day. I'd like to see the stock vs stock dynos as well.

The AP2 (F22C) is my father's.

The AP1 is a friend of mine.

Here's the requested graph comparing my personal K20A2 with bolt-ons vs. my father's 85x89 B20/VTEC CRX:
