With 900 miles on the clock, I just took my AP2 over 6000rpm for the first time. Just once, light on the throttle, and only up to about 7000rpm or so.

Previously people left me with the idea that taking an S2000 to high rpm was like all hell breaking loose. Was this effect reduced by the F22C? It didn't seem nearly as abrupt as a b-series, or even my old RSX (although it did have an intake).

 

take it to vtec with full throttle

 

my sentiments exactly. Rev it till you hit the limiter a couple times, it comes up pretty fast in this car. That way you learn to shift the split second before it kicks in, you have to take it to redline to see power in this car. And yes the rsx type s has more kick, but then again that is i-vtec, better in my opinion. The rsx engine has more potential for power than the s2k it seems.

 

Well, the interesting part is that ivtec is (according to Honda, I think) actually intended to smooth out the power band (amongst other worthy goals, of course).

I'm not saying anything about peak power potential with either engine, just talking about the perceived delta between the two cam profiles.

 

interesting considering ivtec does the exact opposite. it smooths out the power band, so there is no "kick" since the change is not as dramatic.

and the S2000 has more potential for peak power than the RSX-S.

 

yea the S2000 engine has more potential as the head flows a lot more. You can't do much with the S2000 ECU but with an aftermarket ECU you can see some nice gains. The RSX is better to mod when you are on a budget, but if you took both engines "all out" the S2000 engine will make more power.

I bet you've seen some RSXs with impressive dynos. don't forget the RSX is FWD, which has less drivetrain loss.

 

i find the VTEC switchover in my MY04 to be more abrupt than it was in my 02 RSX-S.

try it full throttle as was mentioned above and i think you'll see the difference.

Just curious, do you have any info to back your claims up? Reason being, I have always been a firm believer that the K-Series engines have much much more potential than the F20/F22's.

....

I've always wondered this, but in short, I'd love to see that fully modded F-Series can out perform the K-Series. Pleave prove me wrong.

 

you posted a dyno of a type S making 254whp. 2.5 liter inlinepro engines have made more power than that, and if memory serves me correctly, the 300whp mark was breached in n/a form by an S2000 in 01.

beyond that, the people that know honda engines have also made such statements as well. in fact, even Ultimate Lurker has stated that the S2000 has more potential for peak power than the K20. And he'd probably know what he's talking about when it comes to unleashing power from both engines. lol.
