so I installed my performance mods(dyno)
well, like it said in my first thread, I ordered the following performance upgrades for my baby:
-comptech icebox
-comptech headers
-comptech upper tie bar
-comptech tranny cooler
This week they all arrived, however the tranny cooler is being shipped via comptech, and will arrive next week. Tonight, I had all the other parts installed. I then had the car dynoed. First of all let me say that I'm very happy with my stock dyno #'s! With the icebox, and headers in the car sounds like a JET!!!! however the set-up is still quiet, with absolutely no resonance whatsoever. The fitment was perfect, and the quality of the headers was amazing! guys PLEASE save up your dollars, and go comptech. nothing beats the real thing. Now here's the dyno results:
The thing hauls, and hauls!
-comptech icebox
-comptech headers
-comptech upper tie bar
-comptech tranny cooler

yeah.......I was about to say that also^^^.............get the RT High Flow Cat next,if you really like that sound.............And I feel you on the CT headers,I may just skip the DC's since they are on back order anyways,and get the "real" thing

oh, and he had fitment issues too, with his DC headers, they had to go next door to the guy who specializes in domestic exhausts, for a lot of "banging around". they did eventually get them on though.

hmmm..thats something to chew on huh??I only wish I could have known what I know now and start over,for sure I would have got the CT's................oh well like they say Hindsight is 20/20............oh yeah nice curve on the dyno,you must love to drive your car now

um, not to bust your bubble, but your are on the border line if not running lean, so i'd check into a retune if i was you or that engine won't be lasting very long. you should be no higher than about 12.8, your at 13.5-14 with a retune you'll see and feel a diff also. i'd be surprised if the dyno guy didn't say anything

I'm not going to bash the DC product because I don't know his stock numbers, but there is a difference.

I also had a fitment issue with the rear bank header, but nothing a little bit of tugging and pulling didn't fix. But I paid like 300 shipped for those headers new, and they are making good power. So I'm not complaining.

also was that a dynojet dyno? did you use an sae correction factor or std?

i had OBX's on for over a year and a half now.
and so did many others on this thread.. i believe pure adrenaline also does too. i NEVER had any problems with them and i always felt great about them..
you say the quality is top notch and just praising them so much.. i dont know about you but i spend 200 bucks on mine, you spent over a thousand. for what? for the original brand compared to my exact replica? same bends, same everything, including the pieces being stainless steel.. i think its safe to say that i didnt need to go all out on the money to get the similar big bang that you got.

ok i am confused, vtech controller?? are we talking you adjusting when the vtec kicks in at a lower rpm?? boost, are you running a turbo or a blower?
what i am saying is whatever you are running, your car is running lean at WOT, so eventually your engine will go bye bye. you need a retune to add MORE fuel to the curve which means you probably need a custom tune and then you'll most likely see a little more HP and maybe TQ up top if not all throughout the curve.
take a look at my chart on the ROUSH, notice the a/f ration is below the red line, and how flat it is, thats what you want

Now back to the dyno...I will be bringing mine in this weekend for a dyno and looking at your #'s, I wonder what i will put down. My mods are listed below. Last time I dynoed it, I had I/H/E and put down 200 whp...sad I know. The problem was that the operator told me to run it in 4th gear and because it was such a last minute decision to run it, I didn't know that 3rd was the closest 1:1 ratio. I am also looking into this air/fuel ratio thing. I don't know anything about it at all but I've been skimming through pages on the internet and I will probably be starting a new thread with all the questions I'll have. Don't want to rob this one.
Nice numbers by the way. Not bad for a luxury sedan, right??

To quote from your link: "For gasoline the stochiometric mixture is 14.7:1 in Naturally Aspirated engines maximum power is frequently reached at AFR's ranging from 12.5 - 13.3:1"
Not trying to say right or wrong, your a/f ratio looks lean to me, if your not racing it, redline all the time, no NOS, blower, turno, well you may get away with no retune. But if you retune and add some more fuel, i'll bet you get higher and better overall numbers and it'll pull harder up top without seeming like its running out of steam. i am no import expert etc, but from what i have learned with the american muscle cars, you look border line lean. If your going to a reputable dyno guy, ask him/her their opinon.

I see...so since cars are mostly NA then that would be the optimum AFR? That makes sense and thanks for clearing that up...like I said I really don't know anything about this but I am learning now. I will have to check that out when I get my car dynoed. Okay...sorry for hijacking the thread.
#26
its just something to consider and look at. all these aftermarket companies state "no tuning needing" Bull, you need to check b/c there is only so much the ecu can compinsate for when you add more air coming into the engine and going out. i mean, just a k&n filter, no CAI and maybe a catback or just mufflers, ya, prob no need to worry, but adding CAI, headers, exhaust etc etc etc and you really start effecting airflow more than the MAF can keep up with in stock tuned form.
i noticed when i retuned my bike, it pulled much harder on top and i had a k&n and gutted my cat out of the stock pipe back then, and i was border line lean also, got a new map etc and she pulls even harder if you can believe that.

I am cheap where I can afford to be. I'd rather save 700 bucks on pipes and put that toward better suspension where it really counts for me. It's all personal preference. I'm not saying you made a bad choice; Comptech is at the top of their game and they make excellent products. All we are saying is that they aren't the only viable option when it comes to intakes and headers.
As for your questions, Dynapack, "P" as in pulleys, standard. Extremely high humidity (rain), about 70 degrees, one fan, no cool down between runs.
Since then, it's received more mods and the V-AFCII has been tuned. One of the guys in the local club has a shop, and he just got a brand new in-ground dyno in there over the winter. We're having a dyno day on the 29th, so I should have new numbers that are more comparable to yours then. I do realize Dynapack tends to produce slightly higher numbers, but even then, we're still talking nearly 20 fwhp, or about 27 hp at the crank. Anyway, keep an eye out.

this thread now has me wondering if I'm in need of a retune.never had a dyno done before.maybe its time to stop being lazy and get it done...........Nobody knows of a place in the Bay Area by chance? sorry to hijack
#32
i said i'll bet you'll get higher #'s, not guarentee, didn't say 100 guys haven't done it, but said your borderline on the a/f. just b/c 100 people jump off the bridge and no one gets hurt doesn't mean # 101 will be ok also. my suggestion was to have a pro verify. but, if you insist its all good, then by all means carry on and don't worry. me personally, i'd add some more fuel or at least confirm with a reputable import shop.
