Simple Physics. It take more time for air to travel through a longer pipe than a shorter pipe, unless there is force being exerted on it.

You sir must have a turbonator helping out your cold air flow!

Damn dynos are always lying. lol

 

I'm sure he'll start popping out g-tech numbers soon.

 

lol, i didnt mean for this much to go on from a post

a guy is sellin high flow cats for 350, and resonated test pipes for 350... i kno u said i could get test pipes for 100 used probably, but im tempted to buy new and go for the legal route for hfc's... is 350 reasonable or should i wait for lower?

 

The conditions of the testing were completely different. Check out that thread. The guy comes out and says he was wrong after he got the car re-dyno'ed and then has to come back and clear up that he wasn't exactly wrong, they just switched the settings on the dyno. This was never resolved. I dunno, Whatever my CAI has worked for me. I definitely need to get my car dynoed now, and maybe I'll buy a poop charger and do the comparison myself just because I don't beleive it. We'll see how much free time I have before school starts.

 

hahaha, did anyone ever buy one of those things? lol. I never talked about any numbers, but whatever.

 

I've heard of a few people using them although I've never done it myself. I'd rather just go to the track hehe.

 

alright, back to MY thread.. lol

this is what i plan to get... let me know if theres anything else in between thats essential to making these items work efficiently

JWT w/ ztube $190 (or Stillen w/ z-tube $245)
Kinetix HighFlowCat $350
HKS Hi-Power Exhaust $1290

i think thatll keep my funds busy for a good while

 

Go with a spacer or plenum before you drop $1290 on an exhaust.

 

good point! its cheaper and it also keeps me from dreading the loss of 1300 suddenly.. when i spend in increments of 2-300, atleast it doesnt SEEM like im spending too much

 

Like most of us are saying... JWT PopCharger all the way -- keep an eye out for a used one on here, if you don't like it, sell it for what you paid for it.

 

i had a nismo cai, kinetix plenum, borla exhaust, and hfc, and was only slightly faster than stock z's until i got my ecu reflashed. after the reflash, i pulled on those same stock z's extremely easily.

i had a carchip that i did temp readings on btwn my nismo cai and a friend's popcharger. they both resulted in about the same intake temp after running for a bit, but the pop charger reaches higher intake temps when idle, and the temp goes up quicker than a cai.

popchargers are cheaper and easier to install. cai's are....cai's!!!!

 

someones offering 1130 for brand new hks hi-power exhaust... very tempted to take him up on it in a bit

do most hfc's work with the hks exhaust? what diameter is it? online it says 60mm which is 2.36, but im assuming with thickness, it makes it 2.5"? thats the size i see a lot of in the hfc's and test pipes

 

I ran the Injen in short ram form when I went back to NA (for a horid 4 months). I liked it... It's now sitting in my garage collecting dust. Hint hint, wink wink

 

Crawford HFC's pop up every now and then for ~350 also, I'd look for those (personal preference only). Actually some used ones on sale in the classifieds right now for 275.00

Then instead of the exhaust get the Osiris (since reflashes with more mods are supposedly free) $700, the motordyne plenum spacer (260) and a crank pulley, and a Gruppe-S Y-Pipe ($100... I'm selling it hint hint) and still have some left over.

oh and I've used the g-tech.. well a knock off brand... when I was at the track last friday I timed it. The g-tech was .2 seconds slower than the track ET and 5 mph slower in the 1/4. The 60 ft was almost exact (2.1 vs 2.13) I can't remember the rest for the 1/8th etc. Will have to look when I find the slips. It used to be pretty accurate though, I think it is very sensitive to how it is placed on the windshield (angle etc)

 

Yes Im a chump, I dont believe hype and rock a worthless air restriction in my intake, so what if its at SEMA, Ive also seen BS products at SEMA myself....

You still have no proof, I do, and many others do. Prove it works and then you will have credibility, until then you have nothing.

Imagine having 2 cups of water, one cup has a 3" straw the other a 12" straw, your goal (using 2 people @ same speed) is to see which cup can be consumed the fastest using the straw. Which one do you think will be faster the short straw or the long straw? If you think the long one you need help, these arent Honda Civic's, and RSX's CAI's on our cars are weaksauce. BTW-what do you run with all your mods?

 

Guys i agree with what alot of you are saying when it comes to Pop Chargers Vs CAI. One thing you have to keep in mind is, You are going by a Dyno which does not move. How is a CAI supose to work, while the car is not moving??

One thing i would like to see now that i have a UTEC. Would be to see which one effects the MAF sensor voltage the most while the car is moving. The higher the reading would mean the more air that is running across the sensor. The more air running across the sensor, means more power to be made. Colder air effects this number aswell.

Im not hating on the POP charger, but it does have a advantage on a dyno vs a CAI. Wish i still had my CAI, so i could do this test. I still own a POP charger.

Todd, CAI's like the AEM that position the filter in the wheel well dont get cold air from moving (thats called ram-air, similar to what you have setup), they just supposedly get colder air than underhood, but when the Popcharger sits in the stock Z location where it has a tunnel to get cooler air to the factory airbox the difference is questionable. The bends and length on our CAI's is what makes them junk. Now throw a plenum in the mix and it straight doesnt work the CAI's really hamper performance then. I proved this over 3 years ago, and eventually after testing, Doug Crawford himself admitted online CAI's + plaenums/spacers dont work...

 

is the z-tube just a 350z tube pipe? hence the "z"? just bought a jwt pop charger with "350z pipe"
