had my car dynoed at chasers today. engine wise its stock apart from the 2.25 cat back. im planning on doing a CAI and tuned VAFC II installed in the future .
what do you guys think?

what do you guys think?
Looks like quite a smooth power curve. Bit over 100hp. Not bad mate. Will be good to see the difference some mods will make to the output though.
is this the sport or the 1.8? nice curve

How far into the future are you looking at doing the other upgrades mate. It would be good to see some mods and the new curve. Most dyno graphs plotted on here are finished products and you cant where they started from.. 77kw isnt huge but it is a nice smooth curve though so it will be a great place to start.. What figure you aiming for? Keep us up to date with your progress..
hey are u able to show us more detail..
after u install the vtec controlr ...
coz i want to install as well....
i might be wrong, but I believe VAFC won't do any good to the new civic.. as vtec kick when the gas pedal floored.. correct me tho..
i Dont think so, the vtec kicks in on pressure sensor on the throttle. and also its execute on certain rpm. example if you floor it 100% throtle it will not engage vtec at 3000 rpm. if you get what i mean.Quote:

Keep on it!!
No, R18a's vtec can engage at 2000, 2500, 3000, 3500, 4000 or at any RPM above the minimum. Because, it uses vtec to switch between Atkinson cycle and Otto cycle mode. When you floor your accelerator at above the minimum RPM and above minimum load, vtec engages.Quote:

77kw atw is not bad...
has any1 run a dyno against the sports model?
Agreed.. Get a cold air intake mate, best thing i did for my crx. Sounds fantastic from 4k up but standard below that so its not annoying. Gave noticeable improvement in mid range too. Well worth the money i think..Quote:

dont think this is correct mate, they said that it will gain 11hp (at the wheel they said) using the Short Ram Intake. How come the SRI can gets more power than the CAI?Quote:

(look at the bellow right corner of the first big picture on it
Because dynos are done with the bonnet open. If you drive with your bonnet closed, SRI is like stock. I used to have that.Quote:

This car was pretty high k's and i wouldnt be surprised if the kit it was running standard was well past prime but its pretty cool review.
Anyway, i guarantee you wont be disappointed with CAI
based on prev exp.. CAI will be well spent.. if you get it installed with the other things.. such as piggyback, chip, whole exhaust set, ignition, and not to forget.. great mechanic to set-up.. by the end.. all of these will cost you a fortune.. and it's just a matter if you wanna spend that much..
If you decide to go with CAI only.. there might be a slight improvement.. but I can't really feel it tho..
It's worth it only for the sound. Unless you enclose it and add a cold air feed to it like the GruppeM intakes.Quote:

Yeah, because the transmission case for the auto might get in the way. well, time for you to do SRI and make an enclosure if you want power like I did for my Euro: http://www.ozhonda.com/forum/showthread.php?t=53595Quote:

Ok... mine is the Sports model, so it has K20z? So that means I will get around the same? =SQuote:

one last question from me... Is it worthed install this SRI into my 06 Sports Auto?
Mate its your call, noone elses, its unfortunate that you can't fit the cai in the auto. As has been said you probably wont gain power with sri due to heat soak cancelling gains in flow but it will sound cooler. I myself would try and find a company that does cold air or even custom fabricate something that draws cool air (would be rewarding). Your car though. Hurry up and do some more so we can see the difference on the dyno mate!! I like seeing before and after dyno readouts...
If you don't like the noise, don't do it. :p You will hear it more in an auto than a manual because you usually use more throttle + you have kickdown.Quote:

As for the R18 engine and auto transmission, its a very fuel efficient boat anchor.
