Z1 ported intake, worth it??
Thinking about doing their ported intake before I give the car to them for dyno tuning... Is it worth it to spend 275 on this ported manifold? Any actual gains?

Not based on my experience. Search the forums, you'll see.

All is needed.

I'm planning to have mine done after i install the Z1 header's,,,i recently upgraded the Z1 cai to a high-flow design & want to maximize before re-tune.
It's about moving air in & out of the engine-minimizing restriction....as currently my stock exhaust manifolds/header's are holding it back. |
I know there are 2 shops in the southeast, that have performed this & shown Dyno results...I'm thinking it helps mostly on the top side of the rpm range.
I'm guessing that it depends on what current mods you have will differ in gains/losses...that would suck to lose power after a mid....biggest thing I lost after mods is traction...lol |
motordyne huge gains

Like this...and a very noticeable difference. Sent from my iPhone using Tapatalk |

SOHO Motorsports report's 13whp gain above 7k rpm's...less hp/tq below/but that is with long tube header's & 3" exhaust. 3" exhaust will help for TT application-but seem's too large for N/A |

From a tuner himself he said it all depends on your setup, I personally watched a dyno that the motordyne intake manifold made less power than the OEM manifold. All depends on your exact set up.

Can we stop derailing this thread? I have ported upper and lower and gained power through the whole power band.

install instructions are horrible |
Isn't it necessary to piece the intake manifold with the lower portion too, to see any real gains? I thought there is a second, lower manifold component available from Z1 to pair with their manifold. Sold separately, but really, should be together from what I gather.

Yeah, this thing:

I did the full Z1 kit, ported upper and lower, headers (which I ceramic coated), cat delete and the cold air intake. Had an ecuteck tune done by Jtran. Ended up with 326 hp at the wheels with stock NISMO exhaust Dyno chart attached.

Talk to ZGirl, she recently got the Z1 400hp kit installed on her Nismo and she can have some real life recent opinions of the install and performance gains.

I want mine on the top side (5-5500 & up)

Then you need to stay OEM.
|
The following link pretty well explains the advantages of the M370 (350HR) intake manifold.
http://www.the370z.com/intake-exhaus...tml#post819715 I made a DIY 350HR and can definitely feel the extra area under the power curve when using the stock 7AT 7300rpm shift point. If you are revving higher to shift, the low rpm gains are less useful. |
if you want top end power stay with OEM..the VQ35HR(m370) is great for mid-range if thats where you want it..seriously though if you can cut plastic with dremel you can save yourself a ton of money on the M370 and do it yourself.
everyone of my dynos i made more power on the top end with the stock plenum.. First Dyno with Following Mods Berk HFC Stillen Gen 3 Ark Exhaust http://i22.photobucket.com/albums/b3...311_112738.jpg Uprev tuned with Following Berk HFC Stillen Gen 3 Ark Exhaust VQ35HR manifold http://i22.photobucket.com/albums/b3...ie311/dyno.jpg Ported stock plenum with ecutek tune http://i22.photobucket.com/albums/b3...IMG_2406_1.jpg |
Yerrr
Is it worth getting upt intake manifolds on a completely stock car?

my buddy hand ports them. Friend of mine two different dyno made 360whp with PPe cbe and his manifold. I picked up 14whp in parts of the powerband untuned.
