Alrightey then, here's my second attempt at getting a reasonable number.
After fixing the tension issue w/ the alternator/AC belt, things went much better. Boost gauge still registered a slight drop in pressure upon vtec engagement (prior to VTEC, gauge registers a solid 7-7.5psi). The pressure, however, was kept at a constant level at around ~6psi. At the dyno itself, I saw a constant reading of ~5.5psi all the way until redline. This might explain the loss in torque in the image above. Here's a readout of the relative Air/Fuel readings:
All in all, I'm pretty impressed. The intake showed a pretty good increase (I didn't get a change to quantify it though) above 4K compared to the stock setup.

Removed Resonator = Free
Supercharger = ~2800
Installation = 600
Dyno = 125 (includes baseline, & both JRSC runs)
AEM Intake = 109 (for me, at least)
Gauges = 90
Headers = 270 (spend your money on an exhaust instead of this; it's only used for an engine decoration)
--------------------------
Total = ~4000
Yea those are some pertty good Number man but how much you paid for that jrsc kit ? 3200 ? well if its around here you could've bought a Drag III kit and look at this number
look at this 3500rpm and its at 190whp.. and after that you better hold on tight to your steering wheel!! ... just like to share this with you guys peace.. and the Drag Kit only cost 3200 for it and it comes with all the necessary parts you need ..
I'm glad someone is finally getting some better numbers, though it's still not what I'm expecting. A buddy of mine has a 99 GSR with a JRSC. He making 200hp to the wheels with the JRSC, I/H/E, vtec field controller, and toda cam sprokets. We're taking the car in tomorrow for a new ECU, 420 injectors, and a 8lbs pulley. He's hoping for 225-230hp to the wheels after this. I really think with more tuning and a vtec controller of some kind these dyno numbers for the Prelude will increase. I'm still considering the JRSC, but want to see better numbers before commenting to the purchase. Good job though, keep us posted on any improvements or further mods.

you'd whoop my ass no doubt about it, but still cost/power ratio still seems bad. bolt ons plus stage 2 cams are supposed to yield you at least 200whp (in theory) and thats around 1.5k, another 2grand for 10hp? i dunno... then again the jrsc in theory was supposed to be 240hp, i think an exhaust would give you another 15hp to the wheels if you're running stock from the header back. The stock exhaust system is highly restrictive. We gteched a .4 second consistent drop w/ and without a muffler back in january on a 2000sh lude w/ intake and crank pulley.

How'd you get 1.5K for bolt-ons plus cams? $700 exhaust, $300 header, $250 intake, $500 cams, $200 valves and retainers, $??? installation. Heck, that doesn't even include cam gears and pulleys, the other bolt-ons.
200hp at the wheels is NOT easy with N/A. Sun Dang had 200hp with I/H/E and full Endyn headwork (which includes cams, springs, retainers, etc.) that probably cost him a LOT more than 3k, nevermind 1.5k.
As for everyone saying turbo this, turbo that... I'm sorry, but as cool as turbo is, I'd hate to install and tune it. It just seems like such an insane PITA compared to a supercharger. I'd trust my mechanic with a JRSC, not a Drag kit.
oh i guess i'm going by prices around here. intake 180, header 300, exhaust 500, crower stage 2 cams and valvetrain 640. okay i was a lil off you're right i didn't add up the numbers. 1600 plus install. and i guess some sort of vafc another 300, so closer to 2000. and then tuning and you should have near 200 in theory. jrsc plus what he had is 4k so its still around 1800 more for another 10-15hp.
If i went FI i'd prolly go SC myself so i'm not trying to demean him. I just think the exhaust will make a massive difference if he's stock right now there.
SiBirdie- I am TOTALLY diggin you on those turbo numbers- much better power for the money in my mind, and it doesn't have to stop at 7 psi either. Atomic dynoed my turbo kit at 244 HP at 8 psi, with closed loop dump config., with a 3" custom exhaust. Not too bad. Fmax got very similar numbers on their H22A kit too, and when they changed it to an open atmosphere dump, they gained 50 HP to the WHEELS! So I of course called up King and told them to reconfigure mine to open as well. Although I can probably get 300 HP to the wheels after getting a 3" exhaust and proper tuning, I will SETTLE for 290 or so. Just imagine what I COULD get if I built the bottom up and ran 15 or so PSI. Oh well, I can dream right???
Not to mention I JUST got back from seeing TFATF tonight and DAYUM do I want my car BACK NOW!!! The hell with NOS, I just want some BOV noise! WWAAAAAHHHH-PSSSSHHHHHH!!!!!!
213 HP isn't too bad for the JRSC kit, but I still thought that it would get more than that(like 225). I am glad I went with the T baby instead, even after all the headaches and stuff(I will of course retract this statement if my engine blows up after getting it back-LOL!)

Who has hit 200 whp with only those mods?

peace
Are you looking at the right curve? This graph shows about 80 lb*ft of torque and 120 HP at the wheels at 3500 RPMs.
According to his best run on the top graph (which his dyno plots look really strange, but anyway), he is running 175 lb*ft of torque at 3500 RPMs.
Yep, I am sure the Drag kit comes with -everything- needed to run boost. You won't have -any- problems at all.
