Dyno Day Results - 4th Gen H22 w/ JDM Type-S Pistons and Skunk2 Pro2 Cams
**UPDATE BELOW**
First of all, big thanks to my good friend 92typer for being generous enough to take on this project for me.
Chassis: '94 Prelude VTEC (BB1)
Engine: ('95 H22A1 rebuilt with the following parts at ~85k miles)
-JDM Prelude Type-S Pistons (11:1 c/r)
-Eagle Rods
-Stock Crank Pulley
-Kaizenspeed Balance Shaft Eliminator kit
-Skunk2 Pro 2 Camshafts
-Skunk2 Tuner Cam Gears (not tuned)
-Skunk2 Pro Valve Springs w/ Spring base kit & Titanium Retainers
-Stock Valves
-Skunk2 Intake Manifold
-Professional Products 68mm Throttle Body
-Fujita (F5) 3" Cold Air Intake
Fuel:
-Precision 440cc Injectors
-Stock Fuel Pump
Exhaust:
-GReddy 4-2-1 Header w/ 2.5" collector mod
-Magnaflow Spun Metallic 3" High Flow Cat
-Custom 3" Cat-back Exhaust with 2 resonators and Magnflow Muffler
Transmission:
-Competition Clutch Lightweight Flywheel (13.65 lbs)
-Exedy Stage 1 Organic Racing Clutch
-OBX LSD
Tuned by 92typer on eCtune

Dyno was losing signal as you can see, so obviously the peak torque is wrong. This was our final run. We picked up 216.x whp on another run, but slightly lower torque. Cam Gears have not been tuned yet. A/F was street tuned by 92typer a few days before our dyno appointment. Car was running full exhaust with cat and P/S and A/C is still intact.
A Big Thanks to everyone involved:
Marshall (92typer) - for the engine build, tuning, tranny work, and more
Stefan (onefstek) - for the awesome fab work on the custom 3" exhaust
Chris (racerboyb18c1) - for the work on the cylinder head
DonF and 98vtec for their help assisting 92typer along the way
eCtune - For their great tuning software
Meridian Performance in Bellingham - For coming in on Saturday to let us use the dyno. Tim is a super cool guy and has a great shop. Highly recommended.

**UPDATE: 4-15-12**
================
Went back to the same dyno yesterday with Marshall (92TypeR) to see what the results of my current setup would be and try playing with the cam gears a bit. We were short on time, so only had a chance to try two different cam gear settings. Our first dyno pull before any tuning netted us 231whp and ~160wtq, if I recall correctly.
Setup changes worth mentioning since the last dyno are:
-Private Label Mfg. Tri-Y 4-2-1 Header (previous was GReddy Header w/ 2.5" modified collector)
-3" Short Ram Intake w/ Blox Velocity Stack & Filter (previous was 3" Fujita F5 Cold Air Intake, no velocity stack)

And here is a before/after comparing one of our graphs from our previous dyno session back in 2009 to yesterday:

I am definitely quite pleased with the gains. Clearly this setup is working pretty well....better than I had expected

Was hoping for 220 or more whp. I think we could have acheived it had we not had the intake pipe to throttle body issue that we didn't notice till afterward. I am willing to bet that after we resolve the intake issue and try a real quality header we should be able to at least hit a minimum of 225whp, possibly into the 230's. I would be quite happy if we reached 230whp with how simple of a build this is.
Here's a video of one of the pulls:

DANGGGG imagine if your car was tuned!!!
if its 220 not tuned thats a pretty dang good job!!! keep it up!!!

Nice Mike... Looks like your build is going well.
I think Ill end up going to Kaizenspeed to have mine tuned.

dang i like the cross over into vtec. also love the deep sound you have. those numbers are impressive too
nice setup almost kind of what i have. did you balance the crank and change out bearings also? also try getting another header it might give you some more gains you the usual smsp,rmf,SSR which i have love it and hugs close to the pan its on my thread pics of it
Yeah we used Honda bearings and had the crank balanced and micro-polished. I have a Tri-Y Hytech style header on order, so we'll be going back to the dyno with that, and also tune the cam gears. We didn't have the valve cover "moon cut" yet in time for the dyno appointment, so that is why we didn't tune the cam gears this time around.
How would you condsider your set for street use, daily driver, Idles fine any possible over heating while in traffic? Nice setup by the way
It idles as smooth as stock, just a little more noisy due to the more aggressive cams and valvetrain. I have some videos I'll try to put up tonight showing how perfectly 92typer was able to tune the idle. I'm running an OE Replacement Radiator with stock fans and have no overheating issues.

Here's a couple more videos showing the perfectly smooth and stable idle 92typer acheived with the Pro 2's.
