what next? headers?
 

ordered ark grip exhaust, berk hfc and stillen g3 intake

what next to get some more power out of this thing? headers? what brand?

thx!

If ur gonna stay NA then yea prolly headers and to bring it all together a custom Osiris tune and ur pretty much set.

Most long tube headers are going to make the HFCs unnecessary. It's kinda one or the other.

shorty's make gains ... hence the HFCs are still good ... and the Berk ones are awesome. I am at 323.9 rwhp with your set up except I have Typhoon instead of Stillen ... so shorty's, aluminum pulleys and an ignition amplifier should make 340 :)

Ignition amplifier? Like an MSD ignition amplifier? Please do explain.... What part # etc etc.. I didn't know that that could be done for our cars..

Idk. We already have a legit ignition system, I don't see it doing too much. Stillen headers don't make that much more over stock, gains yes, but hard to justify. Supposedly Momentum Z shorty headers (need the 350Z TP's) do well, but there is not a perfect comparison chart as the only results for them were with VVEL tuning. It was the only time I have ever seen shorties make comparable power to long tubes, so I'm still a bit of a skeptic. Buy in for long tubes are not cheap. Yes they start at $900 for PPE's, but your better off getting them coated, so just say $1100+. Don't remember how much F.I.'s runs, maybe $1200-$1300. Install will be a nightmare guaranteed, either for your wallet and mechanic or you in your garage. Driver side is a pretty awful experience. Yes you will lose the ability to run cats, primarily because your exhaust is a true dual, if it were a Y pipe, Motordynes's XYZ Y pipe gives options.

For other power options, there are still different ways. Pulley's from NST, lighter flywheel, M370 intake manifold (mid range, no top end increase), a tune is recommended, and Jun cams are out but will cost a mint getting them installed. Outside of that, not much else you can do NA without playing with heads or internals and that's another money pit. Bang for buck to go farther than standard bolt on's takes a nose dive after the easy stuff is done.

I like how, even stock, these VQ V6 engines offer great power and torque from the factory.

i have to do more reading... hadn't heard about them before now and im surprised more people wouldn't be running them if its a solid 10whp


headers (long tube) are great if you dont mind running without cats and the pain in the *** to install

Will be putting my headers on tomorrow. Woot

Nice extra everything beer food and hands they'll all come in handy

Which ones you got?

I know meganZ had bored throttle bodies and saw nice gains. I believe 7-9WHP?

9whp being the max seen.

but there is more than just boring out to 62.5mm
the shaft was cut in half and the arrow edged the butterfly plate

im pretty sure there is a picture in one of my album here.

edit; to see the true power potential of this mod , the intake tube,specificaly the MAF tube has to be bigger than stock to maximize the Hp gain.
the OEM MAF tube size is 60mm with the big MAF sensor in there so there is a restriction ,,, the MAF section has to be able to flow more than what it is at the TB to see the result.

The Momentum 350Z DE headers.

I'm just waiting for the delivery of my headers and contemplating doing the install myself at our local hobby shop with a lift or do just not deal with it and pay.

What did you do? If you installed yourself and had to do it again would you just pay someone?

ok I was looking at headers and was wondering kind of what has been touched on here. I'm running stillen gen3's and exhaust ,so I was thinking stillens HFC and headers was also a good route? I want to stay legal as this is my daily driver so does that mean LTH are out of the question?

[QUOTE=Vichtz;2020751 I want to stay legal as this is my daily driver so does that mean LTH are out of the question?[/QUOTE]

Yes LTH are out as well as TPs. You need a cat to be able to pass smog if they smog test in your state

I'm surprised at how much people do headers compared to the previous VQ motor. Most could not justify cost and installation for the gains. Is the gains that much better than the DE motor?

Yes it is. I've seen three cases where they are, so I went this route to. I had no luck with headers on my DE motor before. But with the Momentum headers and the way there designed with the collectors inside makes them better than most. So when combined with our new motors it just works.

Won't the test pipse stink up the inside? you have to use em right?

So momentum are short?

Headers > TP > CBE

?


Tapatalk & such etc

Not really. I smell raw fumes when at ideal or coming to a stop when windows are down. But I love that. I guess you could run HFC from a 350 but dont remotely expect the gains.
Yes.

That's the smell of power.

I bought the same headers along with 350z Berk TP's. SPOHN, I'm assuming you are going to do the install yourself? I'm not sure I'm brave enough to tackle this since I'm in a corporate apartment complex... however since I'm in Texas, UPREV is right down the road so I may see what they'll charge with install and a tune :tup:

Sure am. Tomorrow. It's the third time I've done it so I know a lot of tricks and certain tools to help a lot. Course being the radiator core support is off it's a lot easier. The stock manifolds are off already so I just have to slap these on.

Lol that how I got my Z kicked out of my parking garage but with a short throw

Did u do a before and after dyno comparison??

No I didn't. Every tIme I've been on the dyno before headers I've hit between 305 and 310whp. So I'll be using that after I get tuned with my headers.

Ok cool! Keep me posted when u do pls! Thx

I know TPs would be better but would HFCs really be that bad? Would momentums not even be worth it at that point? Not trying to argue but I really just don't have to much knowledge on the subject :tiphat:

It wouldn't be that bad at all just a little less. There's a lot to gain from these headers from what I've seen so they would be worth it.

Thanks! Everyone seems to love them, I want to do headers but not LTHs so there's such a limited market. Stillen has some but I just haven't seen much out of them in terms of HP compared to others.

i was taking a look at the 370z stock headers , and it looks like they're pretty good out of the factory , and i think replacing these by aftermarket onces won't do much... correct me if im wrong guys.

Stock ones with TP's vs LTH's, I would say at most the difference is 10whp but that's with tuning. Typical is closer to 5-7whp. But one thing you can't beat with long tube headers is the glorious sound that trumpets out of your exhaust. It's a symphony of awesomeness.

I'll let you guys know what I gained with my Momentum 350Z headers (shorty) tomorrow. I'll be at Forged Performance getting retuned. They have a Dyno Dynamics and I put down 292whp on there's (310 on dyno jet) before.

Very interested to see your results Spohn. Be sure to update!!

I was also looking into headers but after reading all this I'm not sure if it's worth it. All I'm currently running is gen 3s and TPs and I was looking at getting the Megan Racing headers. Not sure what to do or if I want a full exhaust first. I too will be very interested in your results Spohn.

Didn't get it tuned yesterday. I was on my way and got a phone call. Some unseen circumstances happened.:shakes head:

I can say even without the tune the car pull a lot harder. Never have I ever installed a single mod and felt the power gains I do with these headers. Straight raw HP.

Man you are really making me want these. My only issue is that I have the FI non-resonated exhaust....my resonated Ark hfc's keep the rasp away but if I had to switch them out for 350z test pipes I'm afraid my car would start sounding like a raspy fart machine :mad:
