It's only a b16 , I was aiming for 170 peak hp out of my setup, which I almost reached, so I'm pretty happy with the result. I like the mid range and torque that I got. Everyone has to remember peak hp isn't everything.
Did you do any tuning? I personally don't think it's bad, especially for a B16. If I'm reading your graph right, it does look like your torque takes a dump right before VTEC though. If you didn't do any tuning, then there still got be some untapped power and powerband smoothening. You're right about HP not being everything, I'd rather have a fatty powerband and 5 less HP than some spike near redline and nothing until then.

No. That's power measured at the hubs. A Dynapack tends to read HP high and torque low compared to the more popular Dynojet. But it is VERY consistent from run to run. But let me give you something better to compare this with. I dynoed my B16A on a Dynapack about two years ago. It was a 1994 USDM B16A running with a USDM P30 ECU. The only mods were an AEM CAi and Greddy MX Catback exhaust. NO HEADER. That setup produced 153HP, 100ft-lb torque. So 168WHP with mild cams, a DC 4-1 header (and it's hard to get much out of a header on a B16A!), and a few other mods is not out of line.

I would wager that your vtec engagement is too late. Try bumping the vtec up couple hundred rpm. You have too much of a "kick" for that vtec engagement to be optimized for maximum power in that rpm range.

What do you have for tuning the car? VAFC? Chips?, AFPR? Hondata? etc?
Something fishy is going on in that vtec engagement area. You should be able to smooth out the transition and pickup some power. You have a 10+ ft-lb jump right after vtec engagment, somethings just not right. Do you have an A/F map with the torque and power graphs?
My recommendation is make a pass with vtec high (ie 7000) and a pass with vtec low (ie 4500) and make sure fuel maps on and off vtec look good. Then overlay both passes and your vtec should be the point were power curves intersect.

That's what happened with me as well. With the street tuning done on my car, VTEC would sputter upon engagement at any RPM lower than 5900, so that's where we set it. As long as you don't fall out of VTEC, you shouldn't be in too bad of shape.

Yea, ok. I was wondering how you were messing with vtec crossover too because you forgot the VAFC in your first post with your mods.
But when you were comparing your motor to the guy with the same stuff with the exception of headwork, you do realize that good headwork will gain you a lot more than most other mods. So the 11 hp difference due to headwork is not unheard of by any means.
I think you are about where you should be

Is the VAFC the first generation or second?
I have seen this from time to time, with people and tuners who do not fully understand what is going on with the VAFC. Even though the VAFC alters the Vtec engagement, the ECU still thinks the vtec is at the original setting. What happens if the stock vtec is 6k and you use your VAFC to dial in 5600, then the ECU is still running the off-vtec maps from 5600-6000. The second gen VAFC has a map to tune this "dead" section, where the ECU is off-vtec, but the motor and VAFC maps are on-vtec.
Oh, and I think your car is running strong, but I am convinced that if I were tuning it, I could pick up some power and smooth out that vtec transition.

I have a similar setup
B16:
Skunk stage 1 cams
SKunk Intake manifold
AEM cold air
ITR flywheel
APEXi VAFC
Chipped P28 (feels)
DC 4-1 Header
Cams are not Dialed in and air/fuel has been corrected. I made 164 to the wheels.
These seem like good numbers and sound about right. Good job.
Are you cams completely dialed in?

Cool then man! I am glad to see that you are making good power. I have my vtec set at 5500 with no problems.
I can not wait until I can completely tune my car to see what it does.
Also I am with you on having a better power ban then peak horsepower!
