Anyone heard of these or try these yet?

My local shop called Stillen about the HFC's to go with the injen true CAI I want to get (Like A.H's and Infinite's CAI's).

Shop says stillen now has an ultra long-tube CAI with the filters behind the bumper and they claim more HP and more torque than Injen (Don't they all!). I don't even see them on their web-site. Supposed to be similar to the G37 intakes just released:

http://blog.stillen.com/2008/10/stil...the-g37-coupe/

The tubing looks to be smaller in diameter than the Injen, and they don't come in black, but they look like good quality. not sure if I want to try these or go with the proven Injen CAI's.

Also, these are metal where they go through the radiator cross-member. I'd think that could be a source of noise/vibration/harshness. The injen has the rubber tube going through that crossmember

 

Smaller diameter tubes have some benefit to them as they increase velocity. Which is good for bottom to mid-range torque and throttle response.

 

ya, i thought the same thing to. Someone is going to have to be the lab rat and test this product out. Im really interested in this product because i could actually not get heat soak and actually get power out of it.

 

Yeah, I'v noticed those a couple days ago... they should be interesting... Can't see it being too long before they come out for the Z

 

I'm sure that gains will be similiar between the two. I would think that the STillen might produce like 1-2 more whp since the crossmember chamber is pushing and bending the silocone that Inejn supplies vs the inflexible aluminum that Stillen uses(jsut a guess casue stillen loves aluminum). Or it might be that mine isn't installed 100% correctly because my driver side tube really has some pressure on it and the silocone is being pushed 1/4 in.


-Arsh

 

They claim 18 whp for just ultra long-tube CAI, it's too good to be truth.

 

nah arsh mine is the same way going thru that hole. im tempted to pull it all apart and take a plasma cutter to it so it has even flow without being squeezed in there.

 

Right now my bumper is off the car cause i'm working on installing headlights and swapping bulbs constantly and it puts pain to my eyes to see that. Why couldn't they just make it so it didn't do that? Did they think people wouldn't notice it?

 

Stillen says that you have to enlage the holes going through the core support on the G37. I suppose it is necessary because it is made of metal tubing all the up as opposed to Injens.

The most significant difference between the two will be if there is any difference in diameter. The bigger the difference in diameter between a CAI and the stock intake plumbing is going to affect AF ratios more. The MAF is set up to measure air based on the diameter of the pipe. Start changing that around too much and the entire program goes out the window.

Who knows if it makes the 18 hp in the 37HR but like Ive said before, if it makes half that to the wheels, its still a pretty good mod.

 

Well, that's for the G37. I agree - still too good to be true. I'd love to see independent dynos.

I'll be the guinea pig for this one...

I'll probably have the shop do a baseline dyno (currently have bassani exhaust), then do another dyno with the Stillen HFC's, then do another dyno with the Stillen gen-III CAI's.

Who knows... maybe the Stock ECU can add some more fuel to make up for more air, but it only has so much range. So if it adds more for the HFC's, maybe it'll be outside of it's range of correction and the CAI will not yield anything. But then this CAI on an otherwise stock vehicle might add some power. There are just too many variables.

Then for tuning... The Technosquare dyno tune is definitely doable, but I'd have to go back down there to change anything.

Alternatively, The uprev Osiris looks interesting, but the Cobb AccessPort Looks really cool. But I'd hate to not have a dyno-tune. Not sure what to do there yet.

After the CAI and HFC's we'll fdo a dyno with wideband 02's to see what the car is doing.

There's gotta be more then one way to skin a 300whp cat - er Z...

 

Let us know how that goes and good luck

 

Re-POST!

 

Thanks, mang! I was wondering when the repost police were coming.

I know it's a thankless job, but someone's gotta do it .

I saw a couple more posts in the intake and exhaust forum after I posted here.

Oh well. It's all about the HR in here

EDIT: Oh, the other post was yours... Sorry! Please post pics and results if you get this before I do...

 

no no no !! sorry bro didnt mean n e thing bad! im not a flamer like everyone else!plus ur link is different from mine.thanx for the link with a better description than mine!

 

I hope the intakes for the G37 fit the 370Z.

 

18whp from an intake for us?
what SCORCERY is this!!???!

i would believe that if 350z's had a VG30DETT or an RB26DETT lol.

 

No worries, man... I'd have posted that link in your thread if I saw your thread first. I am going to call Stillen tomorrow and ask them what's up with the gen-III for the HR Z.

 

After my shop was told by Stillen that this was out for the 350z, i called stillen to confirm and they person I spoke with said NO.

IT's only available for the G37. Stilen said they are researching one for the 350z, but they did not have any projections on availability, which to me means never. Think about it, they say this gets 22HP on a stock G37. Why develop this for a 350z engine that was produced for only 2 years - and those were two SLOW years for z sales.

Instead, put that same R&D effort into the intake for the 370z. That'll get more return on investment ultimately than the 3.5 HR.

Injen it is!

You probably talked to a sales representative that is kept in the dark about products. Looks like it's time for me to be a guinea pig again....

 

How the hell can you afford all this...
