i posted a couple questions on CRSX and a few club members suggested to ask the questions here.
this is what i posted on CRSX:
Hey guys,
I went for my first dyno run on the weekend and i have questions about the results...
First, here is some back-ground info on my car:
-2002 Type-S, 202,000Km (approx. 125-130,000 miles)
-AEM V2 SRI
-Hondata Reflash #4
-Remus axleback muffler with stock piping, hi-flow cat, and I removed the stock resonator
While i was viewing other hondas (S2K's and B18 swap civics) whenever they v-tec, a lot of black smoke would come out the muffler. I had no black smoke at all which made me think my hi-flow cat or muffler is seriously blocking air-flow or one of the 2 is clogged. Some of the S2K guys had stock mufflers and stock cats but still blew black smoke! i was the only car without smoke
I was also under the impression i wouldn't have so much dip @ 5200. Is there something wrong? K-Pro is not an option right now, I only wanted to do I/E/ reflash#4.
i know that every dyno is different, but on Hondata's website my numbers look to be on par with what they're sayin, but on AEM's website, it says just adding a cold air intake would put our cars at 185-190whp. There were Civics with B-series Type-R motors with DC header, exhaust and computer dynoing at 173wph at this same shop. Is their dyno reading low?
I was thinking of putting a bigger diameter piping on my exhaust but i really like the way my muffler sounds.
If i added bigger diameter piping & resonator, would it be quiter than my small 2"piping and no resonator? Since my muffler only has a 2" inlet, i was advised not to put 2-1/4" piping because it would bottleneck.
There are really strict penalties in Toronto for not having a catalytic, so i haven't put on a raceheader yet or even considered it. Plus i don't like the black sut on the bumper and the smell LoL.
I know most of you guys have WAY more experience and knowledge than me, so any suggestions or thoughts would be really appreciated. If I missed any info you guys might need to answer my questions, let me know.
Thanks Guys
