Gauging Interest: 2.5 liter headers

[crayzitalian3]

i have been watching some videos of sentra spec-v's with the stillen headers, will they sound similar to the way they are?

i mean, i think they probably would, but i really hope not, i don't like that kind of sound, but i need to hear a video of these even if it is a teaser clip or something lol. i just want to get an idea

[mikegtr06]

any updates ???

[kyle@stillen]

You guys are joking when you ask for updates right?

It's only been 9 days...

We appreciate the enthusiasm but good parts take time. Even after a part is finished it takes about 30 days to make all of the fixtures and jigs and another 30 days to complete production.

We should have more info around the middle to end of May.

[crayzitalian3]

lol sorry Kyle, its just that since our cars see little aftermarket parts compared to others, we get REALLY excited and jumpy and tend to have little patience!!

[kyle@stillen]

I know, I understand...I'm just messin' with ya!

I should have added an LOL to that post haha.

[Stumpjumper]

just giving you a hard time...and bumping thread in the process. I really want to know what kind of power gains we're talking here.

[bina12834]

did we get a price on these?

[dldjros69]

good parts take time.

Aint that the truth, but come on hurry up...

did we get a price on these?

nope

Base= 123HP (http://www.kandn.com/dynocharts/69-7061_dyno.pdf)Intake = +6HPExhaust ~ +7HPHeader ~ +12HP (guesstimate)--------------------Net HP ~ 148HP

that is the best info given so far

[brokendan]

im sry but isnt tht like a 30% drive train loss? seems a bit much..typically wouldnt tht be more like 15-18%.. then assuming 18%.. 143.5 +6+7+ an assumed 12 = 168.5

[Stumpjumper]

my POS mercury cougar was rated at 170hp flywheel, and dyno'd 131hp stock...I'd hope we'd be higher than that.

Yup exactly... ive mentioned this 15 times before and possibly in this thread. 30% is outrageous. The only thing i could think about would be that they dynoed a cvt but i doubt it.

if the car dyno's that low, we should complain and try to get nissan to do something to our motors like they did the 99+ cobras, they dyno'd a rediculously low number, so ford brought the cars in and added a new intake manifold and a few other gadgets

Well stump if you want to do some more research and an interest thread that would be awesome.

Im waiting til stillen dynos their sentra, ill trust their numbers for sure...

[Stumpjumper]

wikipedia mentioned that several of our QR25DE motors were dynoing lower than Nissan rated them, but didn't state how low

[brokendan]

mine doesnt feel 123hp slow though.. lol. and the new sentras qr25de arent dynoing low. sooo i donno.

[dldjros69]

that is 123 whp but yeah the number is low!

how do you know about the sentra? I dont like the k&n numbers, that is the only dyno sheet i have seen.

[brokendan]

ive been visiting nicoclub.com to check out stuff for their qr25de. thts how i found out the new ser or specv which ever it is.. has a header.

edit: i didnt know you arent allowed to link to competing forums, i wont do it again.

Not much...Just hangin out...Drinkin' beers...You know, same ole same ole.

[crayzitalian3]

Haha thanks for the update

you are correct you got time. Im so excited about these coming out.

Anybody care to shed some light on what i am going to have to do about emissions? Am i going to have to unistall the headers each time i have to get the car inspected.

Either way i dont care but just want to know. Also can it damage the car, installing and uninstalling the header?

[bhs07c]

I noticed you lived in PA dldjros69, I live in VA and if your emission tests and laws are anything like ours these headers won't pass the tests because of the CAT removals. I mean, Virginia is probably the worst place to mod a car, I've gotten pulled over so many times for noise. I just planned on getting my state inspection this month then working on finding a friend that works at the emission tests and would pass my car for some cash for next year.

[LongBeachCoupe]

Find a local shop that will "inspect your car, without inspecting it".They dont have to do any work and you dont have to do any either!

Installing and removing this for inspections will be very costly and time consuming!

Kyle, as always, if you need someone out on the east coast for a demo, you know who to call!

[dldjros69]

I plan on doing the install myself so yeah i guess you are talking about being very time consuming. You are correct.

Im gonna have to talk to my pops about finding some lick em stick em place.

Id like them to make sure everything else is ok though, and just over look the emissions.
