1 hp with a test pipe haha you gotta be kidding! and who do you work for the epa. my opinion is that probably a honda with a test pipe is less polluting than a domestic car with a cat. and as for your setup i said congratulations do you want a cookie? i mean come on this is supposed to be a help board right? then what part do you get off on putting others down? oh wait you are one of those special people with the special freak motors and im the one with the lemon, bash me i forgot. But you cant bash me for lying about what i have.
I'm unsure if you read anything after my rant. I asked who did the assembly and the port job on the head and stated what some problems that you might have right now. Possibly a valve seal problem or a bad port job. Either way, you shouldn't settle for inadequate work and should look for what's causing the problem if you believe there is one. If you're satisfied with the end result then that's great, it's money well spent. The only reason why I provided my dyno was to give you a point of reference to base your gains upon.
As per the test pipe, and this is the last comment that I'll make upon the test pipe issue, the Prelude is no where near as clean as you think. Keep in mind that w/o the cat you're polluting > 50x more than you are with the stock cat. Here's two links, one's of the Prelude's emissions and one's of a Chevy Corvette w/ 5.7 L 8 cylinder motor..
Originally posted by prelude_sh_vtec By the way those are SAE numbers and the humidity was like near a 90%, he said correct those numbers for that and we are looking at 190's.
So is the 183.9 whp SAE corrected or not? First you say it is, then you say if it's corrected you might have 190 . . . . Did you resolve the CEL issue? How about the idling problem? What are the details on your intake & exhaust? I suppose it's probably wishful thinking that you might have a baseline dyno. Also, what kind of dyno was it?
And for those of you who believe running without a cat isn't that bad and you're getting gobs more power, please educate yourself. And even totally ignoring the pollution consequences, how can you stand the smell?

it was sae corrected, 95% humidity and misting slightly, the car made 15 runs, the first and the last were where the most hp was found, the fan that was on the car sucked, my room fan flows more than that one, it was on a mustang dyno also if that means anything. as for the cai it is a cheap obx that is about 2 years old, the exhaust is a custom 2 1/4 inch catback custom made with pipe bender not mandrel, with a apex universal n1 muffler.
A mustang dyno's results can't be compared to the standard dynojet or dynapack. And a lack of airflow (both from the inadequate fan & sketchy intake) would certainly affect the results.
Although, your crush bent exhaust probably isn't hurting that much compared to a mandrel system, since it's paired with the stock exhaust manifold & cat.
So no baseline, huh?

break in period only applies to reground cams. My mechanic said that with the skunk2s you put them in then let the motor idle then you can drive the hell out them!!!

...i don't understand. all i asked you is for a dyno result. I had no idea that you were going to be disappointed with the result. I was just curious since i am about run about a similar setup. Sorry your numbers weren't as high as you expected.
well, i'm glad to see some results from these cams. i for one was tired of everyone getting them, or claiming to get one, and saying "they rock!!!" without any proof.
mustang dynos vary from dynojets and dynapacks, sure, but his numbers look pretty realistic to me.
ill post em soon guys sorry for the delay. and satan i just think the numbers are low due to the fact that it's an obd 2 sh and you 4th gen obd1 guys should go for them, cause it feels way stronger than stock (stock as in no internal work)
Okay I confirmed that the skunk2 website is a typo. THe Stage II specs are IN .475,255 EX .436, 255 so it makes a little more sense. I would say your compression isn't high enough to pull all the power from those cams.

No that isnt correct. Here are the Stage 2 S2 specs:
Stage II Honda H22A 2.2L DOHC VTEC camshafts
Part # 305-05-0205
I called em up and had along discussion with MANY of the folks at Group A. Im not sure who told you there was a typo, but that doesnt seem to be correct at all. The Stage 3 S2 cams havent even been released yet. Measured in the car with the valve lash your looking at just under .498 I believe on the intake side.
