The topic is about how great of a car drive between AP1 vs AP2. Why all AP2 only talking about how fast the AP2 only, and this has nothing to do with topic. If any one ever street racing, they will know that being two cars are equal with over 200hp. Then within 10% hp different are driver race. I don't plan to mod my AP1, but if I do I go TURBO or go home. Let get back to the topic about how the car drive.

 

lol... Please note that F22 is the only Honda high performance engine that delivers torque, has a good vtec boost AND doesn't burn oil like a Hyundai Excel. This is what you call "just another Honda engine"? while you are probably shopping at Walmart for a gallon of low-quality oil, because it doesn't worth paying more for oil when you are just burning it all...

 

C30/C32?

 

This is why I don't post nearly as much.. So much bickering about stupid crap that's irrelevant. I love the S2000, but hate most owners.

 

Qft.

 

No, I posted a chart that shows they have *similar* power under the curve.

2-3 shift at 8200 rpm would put the AP2 at 5940rpm, but to not punish the AP2 too much, lets say it puts it at 6000.
The same shift in an AP1 from 9000 would put it at 9000(6000/8200) = 6585rpm.

Here is what the "power under the curve" looks like for an AP2 from 6000-8200rpm vs. AP1 from 6585-9000rpm:


So lets sum the areas.
AP2 area under curve = big blue rectangle + small blue rectangle + blue triangle
(8200 - 6000)*155 + (8200 - 7600)*(202 - 155) + 1/2(7600 - 6000)(202 - 155)
= 341,000 + 28,200 + 37,600
= 406,800

AP1 area under curve = red rectangle + red triangle
(9000 - 6585)*162 + 1/2(9000 - 6585)*(195 - 162)
= 391,230 + 39,848
= 431,078

Whaddya know, the AP1 actually has more area under the curve...

HA!

No it isn't. Published 0-60 and 1/4 mile times for stock AP1 and AP2 are practically identical.

It does have more torque, but AP1 makes up for this by being able to rev much higher. 10% more torque offset by 10% greater rpm headroom. See above^^^
Actually, the AP1's ratios are tighter/closer. AP2 has a wider 4-5 shift and 5-6 shift (not that 5-6 makes any difference, really, but 4-5 does on a fast track). What the AP2 has is lower gearing in 1-4. But this is offset by having to upshift even sooner vs. AP1.

Increased corner speeds? Wrong again. The AP1 is every bit as quick as the AP2 in autoX, despite being on smaller wheels. This has been demonstrated year after year if you want to check national-level autoX results.

I'm not biased, either, I love S2000's, AP1 and AP2. But the FACT is that stock vs. stock, performance is practically identical. There is no real-world AP2 advantage despite its having more torque and more power, for reasons that are easily understandable.

 

Actually, i think the whole "area under the power curve" isn't really what's important. Otherwise, a 120hp engine that spun to 20,000rpm would have an advantage, which it really doesn't. So feel free to ignore the squares/triangles in above post...

Important thing to note is that the aP1 is making more power than the AP2 immediately after upshifting, so though AP2 makes more power, it doesn't *always* make more power.

In the end, the stock AP2 is no quicker than the AP1. But it would be with a rev-limit bump up to 8500.

 

Beyond stupid.

 

Enough with this dyno plot you found for 2 cars which mean nothing. Why dont you goo look at the dyno section on this forum and compare the 100s upon 100s of dyno through out the entire thread and come back. Why is it that ap1 are putting down 185-195 whp tops when ap2s are putting down 200-220 tops?

Your a dumbass bro, you are comparing 0-60 tims? the OLNY REASON THEY HAVE THE SAME 0-60 TIMS IS BECAUSE THE AP2 HAS TO SHIFT RIGHT BEFORE 60 MPH, after that the ap2 pulls ahead.



HAVE YOU EVER SEEN A ROLL RACE WITH AN AP2 VS AP1??? AP2 ALWAYS PULLS ON IT. WHAT DOES THAT MEAN? AP2 TRAP HIGHER SPPEDS IN THE 1/4 MILE. What does trap speeds mean? faster car duh

 

Refer to: https://www.s2ki.com/s2000/topic/876...t-power-output

We go over stock vs stock, modded vs modded, all on the same dyno, and a lot of the dynos back to back. Irrefutable evidence.
