325whp 227wtq H22

[2point6]

That's almost EXACTLY twice the stock HP!

Scott, that's amazing. This motor (well, in a previous life) has been one of my biggest inspirations since you were making 249whp and ripping on Z06s with with the CB7!

Thank you Deev. That seems like so long ago now... I am looking for more out of this engine really soon I think there is 20+ hp to gain still. We will see...

You wouldn't happen to be able to post a video of this engine in its current form would you?

Last time I heard it, you still had the Skunk 2 or Euro R manifold...

Yet another bad ass motor from Scott. There is ALWAYS room for improvement in any engine. Be proud of your results. Many people try to build an engine like this and fail.

While you weren't impressed with the horsepower, my concern was more so with the torque. Perhaps this is maybe because I'm not an expert/lack of experience, but I always assumed that with N/A builds would always have the numbers relatively close; I guess because that's all I've ever seen with my own eyes. I just figured a motor with 300 or so whp would have close to 280 or so wtq. Is that also a result of mix-matched parts?

[dbsharp]

When you make peak power around 8500 rpms, you will never have close hp and torque numbers.

Congrats on hitting the 325.6 WHP 227.3WTQ range. I'm sure you will be able to squeeze even more out of that thing. Seems like every time you post there is another 40-50whp found.

Don't beat yourself up. What you have there is an accomplishment by far, something that gives others inspiration, and a gateway of hope for many; you understand!

With that being said, from mine and possibly other's perspective, amazing job. Great build. I am very impressed and enthused. Keep up the good work as you've succeeded extraordinarily. A pat on the back is well deserved.

When you make peak power around 8500 rpms, you will never have close hp and torque numbers.

So the lower in the power band you make peak power, the higher the torque numbers? Is that a rule of thumb for any build or just N/A ones?

[dbsharp]

hp is a function of torque with respect to time. when your peak power is around 5252 rpms you should have pretty similar numbers.

180-190ft-lbs torque, ~80% of peak developed below 5500 rpms! These low rod ratios are autocross motors no doubt! This motor in a civic would rape turbo cars out of corners! For a drag application, why not make the rod ratio higher, spin the motor faster and make more peak power?

Awesome numbers!

thats what i did, but getting out of the gate and passed the 60' in a decent time is half the battle.

Great #s, but w/2.5L, 15:1 comp and your expertise its to be expected....

Kinda curious to see what you could do w/a stock block H...

With a stock block you can still make a good amount of power.

P'n'P head
Bisi stg 2 cams
Bisi header
2.5in exhaust
maybe even an IM swap w/ CAI

All with a tune, of course.

id make a number of changes to that list, but thats the jist of it.

Actually, if you look at various power curves of pretty much ANY healthy DOHC VTEC engine, they have relatively flat torque curves. He simply managed to improve both ends, while keeping the shape flat.
