How does the S2000 get so much HP out of a 4 cylinder?

[AgaBoogaBoo]

What has Honda done special with the S2000's 4 cylinder engine to get 240HP out of it?

 

[Jfrag Teh Foul]

Is it supercharged?

High rpm. Good breathing.

 

[NutBucket]

1.) High compression (11.1:1)
2.) Astrnomical Redline (8k)

Consider that horsepower is a relationship between torque and rpm so the same torque at higher rpm = more horsepower. That's the basics of it.

Aye

So it's got good airflow or something?

It's a higher-reving engine.

How about you use google instead of creating a thread every time you have a question

ATOT is easier :0

An engine is a big air pump right? So the more air you move through it per combustion cycle the more power you make. Breathing (head design) is a big part of building a high-performance engine.

How does the engine in an S2000 compare to other Honda cars? Any others use same engine?

Nope.

S2000's engine is specific to that car. Previously the Prelude had a 2.2L rated at 220hp. The new Honda 4-bangers use a completely different version of VTEC so they're really not comparable IMHO. If one must compare there's currently a 2.0L and a 2.4L both rated at 200hp (Acura RSX-Type S and Acura TSX, resp.).

revs to 9000 rpm.. must sound like paradise..
i also wonder how they managed to squeese240hp from 2.0 litres and make it so reliable.. with just DOHC and variable valve timing.. no turbo, supercharger.. :Q

the new one only revs to 8k... but has a wider torque band. 9k is freakin loud even from inside... :Q

hondaboy, get your specs right, the first iterations had 9k rpm redline.

I never stated first or second gen, and neither did the post Tho, notice I edited it. I had first put up 9k for the redline

The Prelude has a max HP rating of 220? I have the Prelude manual SE 2001 and it's rated at around 195-200HP. Unless the US has their own version that Canada doesn't offer? *scratches head*

The Prelude redlines at about 6500rpm I believe. Must be a really smooth engine to be able to stand redlining the S2000 to 8/9k rpm. Or just the mindset that if you're prolly revving that high, you don't give a damn about speed, just wanting to beat the car next to ya

It's because they use hamsters on steroids driving the spinning wheel. Other car makers have to make do with all-natural hamsters.

Yeah, it's terrible, I tell you.

 

[CraigRT]

I thought the Prelude revved a lot higher.. when I shift my Neon at high RPM I shift just before 6,800 (fuel cut) so the Honda has to be able to go higher than that !!!

 

[Howard]

BTW, they make turbo kits for the S2000 now.

My RSX Type-S (Acura) has a 2.0 liter 4-cylinder with 200 bhp and a 7900 rpm redline. Not exactly the same, but it's still a nice engine.

hp = (torque * rpm ) / 5252 (where torque = the amount of torque at the given rpm, not the max rated torque)

Honda engines have high rpm redlines. You do the math.

The last ones were rated at 220.

Yes it is. Nice car BTW.
