With only an Intake, you're making 121whp? What kind of dyno was this?

not only an intake, axle back also. Racing beat axle back (from MP3) Injen CAI, UDP ( yes I know it ONLY frees up hp because its light and doesnt provide more power, hehe) I was kinda surprised to see 121 whp result. Did it on Kooldino's PDA. About 4 times in a row, 3rd gear pulls. Result was consistant. (kinda exadurated about real dyno, but that this is pretty accurate, NOT as accurate as 'REAL' ones)

Minishotglass: butt dyno's? I took my car to the REAL dyno, and saw increase. Stop living in denial....why dont you be a president since you know so much (boom08)

Before the intake camshaft install I had 121 whp. Now its time to dyno the car again.

DiS:
I wasn't aware that PDA's or G-techs were even considered a form of dyno to true enthusiasts. Living in denial? Do you even know what denial means? The definition of denial is refusing to believe in the truth. The truth is you won'tsee 121whp from an intake, pulley and a muffler. If you had 121whp from a REAL DYNO and not some fancy g-tech performance meter thing, pigs would fly and money would grow on trees. Who ever said the president was a know-it-all? If that was the case, our asses wouldnt be stuck in some futile war and our tax money would be used for something to better the whole world than to help some foreigners rebuild their hellhole.

Back to the issue at hand, if you knew anything about basic scientific method (yes the stuff from MIDDLE SCHOOL) you would know that performing an experiment (trying to find out whp in your case) and getting consistent results (im guessing you got around 121whp four times in a row or something) is USELESS if PERFORMING the experiment itself is flawed. Its like saying I measured the wheelbase of my car four times and got 5 ft each time, but the tape measure I was using was slanted each time. Performing the experiment wrong four times says nothing about accuracy. Dyno with a REAL dyno no exceptions.

You still havent told me the temperature of the CAI tube before throttle body after a 30 minute drive yet. You havent told me who the "others" were that said a CAI was better than SRI. You're previous posts you refer to "feeling" and increase and mentioned nothing about a dyno. And now you say you got 121whp from a PDA? Sounds to me like you're the one living in denial because you're either ignoring the questions I asked you, or know the answers but don't want to admit them because you know these answers would go against what you're arguing for. And Im sure other enthusiasts like Gen1GT, akhilleus would agree with me here.

I rest my case and I assume that the starter of this thread (crazywolve) got the answer he was looking for.

P.S. crazywolve: don't believe all the hype from marketers/advertisers/ricers, make sure you understand the scientific process in solving problems and have soild REAL WORLD PROOF before paying big bucks. Have a good day

DiS, scroll down and see all the mods Andrew Bode(twilightprotege) has done to get 124whp.

Yeah, they are right...i would bet u are putting down maybe 110-115 the PDA dynos and g-tech arent nearly as accurate as a real dyno. Although it can be used to show increases from modifications. This intake debate has been discussed before though and i think that gen1gt and I have also gotten into this before as well. I stand by my assertion that the CAi and SRI both can show "gains" in certain areas of the powerband. They are also designed for different types of engines. As the link pointed out the SRI will show gains but is better suited to very high rpm whereas the CAI is better high mid-high rpm.. so like 5.5k vs 6.5-7k rpm I dont believe the CAi is hype at all...that is absurd. It would be cool though to do a head to head comparison on a real dyno of both SRI and CAI on a protege...probably won't happen though.

 

[Gen1GT]

Well, you could make it happen. Find a guy with a short ram, and bring both your cars to the dyno. Baseline your CAI, then swap in his short ram, and do a couple runs. Then swap cars, and do the same thing. Then bring your cars to the track, doing runs, then swapping intakes. See which intake made each car more power, and got the best 1/4 times....

 

[Kooldino]

Hey, it may not be 121whp exactly, but it's a reasonably close comparison. I pulled roughly the same numbers on my PDA dyno as I did on a dynojet. The PDA dyno usually spits out a pretty reasonable number.

 

[akhilleus]

Yeah but dis did tell me that the pda was throwing some crazy numbers out after the intake cam....i might have misunderstood him...but to my knowledge it sounded that it was a "rough" estimate.

that was Dana's 'dyno', hehe. Well maybe because my s*** was messed up regarding the tensioner spring and CEL, and maybe thats why it was throwing different numbers all those 3 or 4 times when we tried after the cam install.

But yea, as far as those links, I agree. Definetly on some cars it will show different gains. Some stock cars have even more power than same stock cars in comparison. Meaning... My friend has a 2002 Nissan Sentra SE-R Spec V, and he dyno'ed his car (when it was stock) against same year and model Sentra, and other Sentra came out with few more ponnies than my friend's. Factory beast anyone? (whip). Not implying that my car is one, but who knows...Maybe out of like 10,000 protege's there are some factory beasts, hehe.

 

[Gen1GT]

My car is one such engine. It seems to run stronger, go faster and put down more power than it should. Everyone else with a BP baselines at 105-107, and I baselined at 110. I think the guys at the factory just had a good day....

Also remember that the engineers at AEM saw no performance difference between SRI and CAI, so they didn't release a CAI for the Protege.

I have the AEM SRI, and I can tell you that:
1. It gives a louder and nicer sound
2. My butt dyno noticed a difference in throttle response, which I would attribute to low end torque gains.
3. My car performs no worse when hot, so I don't buy the heat soak thing that much, in that whatever heat soak is occuring, its still better than the stock airbox (where the restrictive intake's "mouth" was placed right over the rad with no free flowing air path leading into it).
4. I like the look of the SRI in my engine bay:

Thus it has value to me and for the cost, it was as worthwhile an investment as any other I see people make for under $200 on their car (spark plugs, spark plug wires, etc.)

I can't believe my one curiousity question caused this much controvery LOL so from what it ALL sounds like, I think I will prob go with the SRI. Now all I gotta wait for is the cash flow to support one.

Kewl man! I used to have SRI but, it was ebay one and wasnt perfect fitment (rubbing against few things like Master cylinder booster and its steel line) Thats why I got rid of it. I just wanted something that looks good, and I didnt mind paying 200 bucks for CAI just because its perfect fitment and there are no issues with it. AEM SRI is perfect fitment also so no one has problems with it at all. Everyone has his/her own tastes.

Good luck and mod away, hehe.

 

[aceP5]

Wow, that was some argument there . . .

All I have to say is something I really believe in. Who cares about what dyno numbers you get? As long as you think/feel that your car is faster (i.e. butt dyno), that is all that matters. In reality, an Intake won't make your car that much faster (probably just a split second on the 1/4 mile). But if you enjoy driving your car more, THEN THAT IS ALL THAT MATTERS. Making an already fun to drive car even more fun to drive is a good reason to get an intake. To sum it up, I don't really care what my 1/4 mile time is or what my whp is. I just want to enjoy driving my car. That's what its all about. That is what you will notice every day. Just my 2 cents.

I noticed 3 things when I replaced my stock airbox with a conic filter (aka discount WAI )

1. Louder engine
2. Better Mileage
3. Cooler temps

why? The stock plastic piping was designed by a frikkin genius. He pulls in the air through a tiny slot in the grill. Passes it through some tubes OVER the exhaust mani (props for the engineer who slipped this brilliant idea past the others without getting tarred and feathered) and then through some bends, through the filter, then into the engine. This equates to:

restriction + hottest thing in engine heating up piping (good thing there's a heat shield there (yupnope)) + more restriction + filter = engine bay starving for air, and being fed hot not-so-delicous air.

Replace crappy plastic setup with cone filter and:

warm air from fans + filter = breathy engine that's ready for girls in bikinis to dance around it

Results may vary, but those were mine. Can't fight actual numbers with physics mumbo jumbo. We'll let that placebo to the white coats to figure out. I'll say SRI = worth it.

Just did a little test after reading this thread. I happen to have a K&N Typhoon CAI on my MP3 for a couple months now, so decided to convert it into a SRI last night just to see if it makes much difference. To my surprise, the difference IS pretty noticeable.

With the CAI set up, I lose a bit of low end torque, most noticeable around the 3000-4500 rpm, but pulls harder than before after after 4500rpm. Gas mileage bump up to 29mpg from 26mpg.

As a SRI, it pulls quite a bit harder at the low end at around 3000-5000rpm, without the lacky feel as in CAI, while it doesn't seem like it loses much at the 5000-6500rpm range. Not sure about if the gas mileage is going to take a hit though. I'll find out after giving it some time. And the noise does get bumped up to the next level. (eek2)

Now that I get to try it both ways, I think I like the gain from the SRI better, as the gain is more noticeable and more usable. The car does pick up a bit faster from a stand still. But the extra noise can get annoying if you prefer a quieter ride. If the gas mileage of the SRI manage to be pretty close to what I get from the CAI, I think I'll keep it as SRI in the long run. Though switching it back & forth is just a matter of loosing up a few screws.

sweeeeeet

 

[Gen1GT]

That's awesome. It's good to have people taking the initiative and prove things, rather than just talking about them. I'd have done this long ago if they even made intakes for my car....stupid Airflow Meter.....

 

[protege02]

this might be off the subject cause its a new question but since people are gettin mad about asking the same or similar questions i decided to ask here since its the topic. everyone is going along with a shortram intake? so which one would be better aem or k and n? im thinking k and n cause its universal. you get both sri and cai. i know aem is $190 and k and n is $260 at protegegarage.com.

 

[1Canuck2]

I have the AEM SRI and I like it a lot, its very well made and has thick walls. Many peeps have been happy with the eBay SRI (sometimes sold as Bomz or Ractive I believe). I think the walls of the eBay SRI are a little thinner (more heatsoak?). The K&N products are very well made, but I don;t know that they are worth the extra cash.

FYI, AFAIK the filter on the AEM is an OEM K&N branded as AEM

OK too many initializations in that last sentence FWIW. LOL and ROFL, etc etc

 

[MPChi]

I guess depends on your budget. It sure is nice to play around with the K&N Typhoon as you can test out the difference of CAI & SRI to pick your liking. And its very well made. But it does cost more. If you feel like going for SRI only & save some money, then go for AEM.
