Well I decided to get my car dynoed again for you guys. I spent $75 so if anyone wants to paypal donations to berberoglu@yahoo.com that would be great

RED is the before dyno from last year:

-NGK Iridium Spark Plugs
-Ground Wire Upgrade
-Sun Hyper Voltage System
-Apexi VAFC-II
-Ebay Ceramic Header
-DH Racing Ported Head Work
-Thermal Rear Section Exhaust


BLUE is the after dyno with these changes:

-Stock double plat plugs
-Kamikaze header
-K+N Typhoon intake
-stock exhaust
-AEM power steering pulley
-throttle body heater bypass
-fp60 fuel system cleaner

Also note that the after dyno was performed at 75F temp, and the before was done at 55F. Looking at the graph, the hp barely goes up after 5k and drops off early around 6k. But look at that torque. The only place it dips is between 3.5 to 4k rpms.

Also the a/f didn't get tuned the second time. It's a bit lean and then gets very rich after 3k rpms. Is this okay?

Here are the vafcII numbers.

2600 +4
2700 +4
3000 +4
3400 +4
3600 +3
4000 +3
4400 +3
4800 +3
5200 +3
5800 +3
6400 +1
6900 -2

Comments and suggestions are welcome. And remember this is done on an auto trans I guess I'm happy overall.

eh? when did u get the typoon SRI?

I could have sworn u were always rolling with stock box or the FIPK.

hmm.

thats an auto EX right? not too bad IMO. the first dyno from last year was obviously better.. but thats a 20 F degree difference... I wonder will it affect it THAT much though..

I have no idea how running lean with those bolt ons will do.. if the tempt was the same, you can probably identify the issue better..

shoulda try to get the condition the same, at least u can sorta compare differences.

 
Rep Power: 812

ya well the only drop is only for 500rpm between 3.5 and 4, I don't care about hp after 6k. They say that every 10F drop = 1% hp gain. So that's +2whp, prolly more cause everything won't be super hot under there. I can feel the gains and am happy. Stock intake won't be goin back on.

I just got the typhoon about a month ago. I like it better than fipk because it doesn't get noisy below 4k. fipk was alot louder.

Final plans are to get aem cam gear in august (when backorder ends), tune that, and then tune the vafc one last time and call it a day.

not bad ... only gained 1 peak whp ... but it added a fair amount in midrange ... it seems top end suffered a bit though =\

+ paypal

 
Rep Power: 812

ya do you think because the stock muffler is back on? it was a bit disappointing compared to the hp dyno that K&N did and gained 4-5whp.

 
Rep Power: 0

Its most likely the stock muffler.

 
Rep Power: 289

Strangling the exhaust fumes...LOL I would think the stock muffler would have a lot to do with it...also the temp change should affect it but I wouldnt think you would suffer that bad...as far as lean/rich someone else is gonna have to field this one!!! Good numbers tho!!!

 
Rep Power: 0

i just took off my Typhoon and i definatly noticed a difference in power... i cant wait to put it back on

 
Rep Power: 362

yeah, it may be the stock muffler ... something is definitely choking up the high rpms so it's either the stock muffler or maybe the factory head (I see you used to have a ported head with the 1st dyno).

I think the absolute best HP-making street bolton setup would be:

Injen CAI w/ custom velocity stack
free flowing exhaust*
DC Sports Race Header
TB heater bypass
Lightweight rims**
8 pound flywheel
UR crank pulley
Denso IK20's
Power Steering removal

*free flowing exhaust would be jdm spec Greddy Evo2, Apexi N1, and perhaps some others. Greddy Evo2 US Spec and Tanabe SRM are bottle-necked since they have about a 1" section in the piping where it is 1.5" in inner diameter.

**lightweight meaning 15 or 16" rims, 14 pounds or less



that car would make some decent power ... I would do it if I didn't have other plans. I'm sure that setup would make at the LEAST 125-130 whp

 
Rep Power: 368

I think he still have the ported head though. he just meant those are what's been changed/added on.

wonder has anyone tried the 'new' DC race header yet.

 
Rep Power: 812

Yes still have the pnp head. Is there a way to put the new rsx-s exhaust on or something? I though t I remember someone doing it here. The muffler was a valve that opens and closes at low/hi rpm.

cold air is out, i'm scared
exhaust, where do you get jdm greddy?
lightweight rims maybe later
crank pulley hell no
iridium don't last more than 15k in our cars
i need ps (already has pulley anyway)
flywheel (I have auto)

thanks for suggestions tho. I will look into some of em. I think the auto is making it twice as hard. Most dynos I've seen have the auto at 90whp base, most manual start around 105-110whp. Plus the tranny steals power with whatever mods you do. I think I'm gonna hold off on any major mods. If I end up keeping the car after a few years from now, a k20 is goin in there most likely, even if its just the si/base rsx one. Throw a few boltons, hondata, and it'll be plenty of power for me.

so you definitely reccommend the typhoon over the FIPK, correct? Did you feel any differences when you drove, other than sound?...and where did you buy it, I dont see a whole lot of retailers selling K&N stuff

 
Rep Power: 812

www.cardomain.com and you have to search under performance parts. Look at the other site www.knfilters.com to find the correct part number for your car. They have different models so be sure you get the right one and color you want (cold air or short ram).

I had the fipk and felt similar gains with the typhoon. Both have great throttle response from a stop, but the typhoon has more pull in the lower rpms, as seen in the dyno. Yes I could feel a difference with the typhoon, especially on hot days. It would still be responsive even tho the tube felt like a stove burner. Also the typhoon looks nicer But the biggest reason I decided to keep it over stock was the noise. I can make it shift around 4k rpms and nobody would hear it unless I pressed the gas hard. The fipk was actually noisy above 3k and just got annoying. The sound wasn't all that good either being the tube was plastic. And typhoon is cheaper! $180 shipped for me.

yeah i was the one with the rsx-s exhaust. ONLY the new 05 type s and DC5 ITR mufflers have the valve.

Hmmmm maybe i'll dyno my car this week see what i get with my iceman and other mods.

 
Rep Power: 812

yes dyno please. Also how did you get the exhaust to fit? where did you buy?

 
Rep Power: 301

i bought mine from jdmtheory.com (pricey $150) and i had it welded onto my existing custom catback. check clubrsx too. I've seen them selling for $200, the whole 05 rsx-s catback.

 
Rep Power: 362

hehe there is a shop in LA where I got a full dc5r catback for $250 picked up ... good price ... there are always people selling their 05 dc5s exhausts on clubrsx. I've seen them as low as $200 + shipping ... not "cheap" but then they are new and are good replacements to dc5r exhausts ... (because those can run very expensive)

as for the power steering issue ... all you have to do is remove the belt ... it's very easy and takes about 5 min ... you could even do it at the dyno shop

I seriously don't know where you can get the jdm greddy evo2. I am 100% positive that there is a jdm greddy version ... or at least a "non usdm" version. The one I ordered off ebay had bigger piping at the axle-back and and the B pipe was all one size.

my friend (drivetofast) got a greddy evo2 through another member on here and on the bottom of the muffler, it said "US Spec" ... which I did not notice was on my version (because I verified it).

if anyone is truly skeptical, I'll get some pics if they want me to

on the cardomain site it says that the filter is convertible from a cold air system to a short ram system. In your pic it looks like you went the short ram route, correct? Do you think you'd make any more gains if you went with the full cold air intake?

the page that I'm seeing this on is here: http://www.cardomain.com/item/KNN691007TR

 
Rep Power: 812

the sri makes more power and doesn't have the chance of sucking water in. That's why I went with it. And the cold air pipe is still gonna get hot anyway. But like I said, the sri is more of a torque intake. If I floor the gas, I don't really feel much, especially in the upper rpms. But accelerating from a stop up to 4k is much improved. Just the opposite of what most people think I guess. The sound is kinda ricey too if you floor it, but just mashing the gas after shifting to second gives a nice deep tone. Overall I think its worth getting.

thanx gear for the PM! =)

this is definitely interesting.......i might as well getting an sri... =)

anyway, one thing about ngk ix, i've been using em for more than 15K...and they still give me 360+ miles w/ 12 gallon gas....

wonder when they're gonna start dying...lol...i hope not....

 
Rep Power: 812

i'm waiting for winter to see how much better it feels.

 
Rep Power: 301

i'm gonna call some dyno shops tomorrow and see how much & when i can dyno this week.

just a quick lil Q: why'd you choose the K&N over injen or aem? just in terms of price or is there a small design difference between the three?

 
Rep Power: 812

I had aem sri and it sucked in every way. Then I had fipk but didn't like how loud it got. Typhoon is similar but more quiet and gives better low end in hot weather. K&N seems like they put alot of research into it. Yes they all have different designs, too.

 
Rep Power: 270

just to double check and ease my mind any intake system that fits for yrs 2001-2003 autos will fit a 2005 auto correct?

 
Rep Power: 812

yes same engine. the only fitment issue is with cold air intake and autos/manuals being different.

 
Rep Power: 0

I read that you posted that the fipk and the typhoon are similar. But my question is did they both pull the same and were they similar in the power aspect from low end to high end? Was teh only difference the noise? I am going to be buying on this week and i have decided typhoon or fipk, i looked at the injen sri also. Tell me what you think. Will the k &N give the most gains. I know this may be a lame question but did you notice better fuel economy with it also going from stock airbox to intake?

 
Rep Power: 812

After installing the intake and using fp60 for a month, I got 4mpg better highway miles. The fipk and typhoon give the same power it seems as far as response and low end, maybe the fipk gives a bit better hi end. But on a hot day like 80-90F, the typhoon is hands down the better intake.

 
Rep Power: 0

I believe you but i would think the fipk woudl be better on hot days because of the plastic tubing. Thanks a lot though. The typhoon is cheaper and K&N says that it gives morepower than the more expensive fipk. Gearbox you think the intake was worth it over the stock airbox?
