Horsepower vs Torque F22 vs H22

[illinois_erik]

id just like to say that:

[gloryaccordy]

I agree. VVT, VTEC & DOHC all make tuning and correcting for improperly spec parts easier. You can basically throw together a DOHC VTEC with adjustable cam gears and any mix of parts to make decent power. Not so easy on the SOHC non VTEC.

But the respect

The novelty

Lol.

Seriously though a high compression ITB'd F22 has old school appeal. Like a big block 4AGE. I am not sure the Accord is the chassis to exploit such an engine though. It would be like a 20V in a Camry.

[GhostAccord]

Yeah I would love to drop it into a Del Sol.... but who am I kidding, I love my Accord. Sooner or later it will have that old school F22 running in it.

To the op.
It's not simply the peak 20 lbs of torque advantage the h has over the f that makes it a much better motor. It's the increase in torque over the entire rpm range and the length of the rpm range the torque is higher that makes it a better motor. Torque vs HP is hard to explain but once you get it you can't explain it either. I will try
I can generate 500 lb ft of torque at the wheels with a breaker bar, 5 ft cheater pipe and a 36mm socket. Guess how fast I go? That's right slow. My breaker bar torque maker moves at 1 rpm. That is not quite 1/10th of a HP.
Next a motor makes 300 lb ft of torque flat curve at 2000 to 4500 rpm (redline) like a deisel or low compression 454. Still slow. It does not make 200 HP untill its above 3500 rpm then like 270hp at 4500 rpm then shift. Only had 1000 rpm of respectable HP.
Next we will look at the 324 lb ft peak torque porche 911 gt3. That is only a 24 lb ft difference over the example motor. It makes peak torque at 6250 and redlines at 9000 making 475 HP at 8250. This means it produces well over 300 HP for over 3000 rpm. Now that's fast. Having never seen the torque graph I can only guess it makes over 200 HP from 4000 rpm up. That's 5000 rpm worth of respectable HP.
When power is made over a larger span of rpm it allows for lower gearing and more gears. We all know the difference in pull between 1st and 4th.
More torque isn't what makes one car faster than the other. More torque at engine speed does. It takes a balance of more torque and rpms.
A motor can make less peak tourque than another motor and be a faster motor because it makes torque over a longer range of rpms (f20c, k20a) the h23 vtec makes more torque than both and is faster than neither.

i can promise you one thing, the f22 with proper bolt-ons has plenty of torque across the rpm range. i literally build over 80% of my peak torque at 1500rpm and dont drop below that until almost 6800rpm.

and this is a result of that broad power band and close ratios.

Again, stock to modified.

An H22 runs about 90% of its peak torque from just about 2,000RPM and keeps it there till nearly redline (which is higher than where you are at).

Give the H22 the same proper bolt-ons, and it still wins.

That's awesome man. What kind of clutch and flywheel are you using? Amazing your'e using a stock block. Builds like yours make turbos seem silly.

I wanna get a list of all the things you did to it.


EDIT;

No, forget what I said, turbos are not silly. bet he has fun trying to get all that power to the ground.

[jdm92_accorn]

its actually stock block and stock head, lol. soon as i find a good f23a block and a new head i'll be hopefully faster than before. clutch is exedy oem replacement and flywheel is 8lb fidanza.

I know that's what I meant, stock block. But you do have a bisi cam don't you and springs?

Exedy oem replacement is what I will hopefully be using for my 5 speed swap with a stock flywheel.

Pretty cool man that you did this, what do you think was the key in all this the tune? You do have the coupe, I didn't know that.

Edit:

Sorry I didn't read your thread.

[jdm92_accorn]

actually the camshaft in that video is a web lvl 1 regrind.

Dog who tuned that for you, Yoda? And you just have bolt on's with a cam? Do you wanna sell that web regrind?

I asked Phearable.net about a street tune and have yet to hear from them.
