I'll get to the point with this one - who here is interested in some HFC's being developed for the 7th gen Max and would grab some if they were available? I'm talking with AAM Competition (a local Nissan/Infiniti pro shop - http://aamcompetition.com/) about taking my car for a few days and fabricating some bolt-on HFC's and also looking into some dyno pulls (yes, even rough numbers from a CVT dyno pull are still helpful to see) to see what gains there would be.

To put it simply this isn't a thread to debate the CVT, dyno's, AAM, or anything else really. Just gauging interest from the community in HFC's. I have no information on pricing just yet, as the title indicates this is just a interest/feeler thread. If there looks like a decent amount of interest we can go from there.

 

Im interested in anything that will make this car faster! That being said, i dont know what an HFC is, but im guessing after a quick search its High flow cats?

South Carolina doesnt have inspection, so again anything that makes power, regardless legality, im interested in!

 

Yes, HFC's are high flow catalytic converters. They'd replace (direct bolt-on) your OEM cats with higher flow cats (basically with less restrictive material in them) improving air flow. This is one of the last parts we need for the 7th gen to remove restrictions from the exhaust system (aside from headers but me personally I'm just doing HFC's)

 

I would love some, I put some HFC on my truck and it breathed way better. Not sure about the sound as I had headers and full exhaust on it, will it give you more of that race car sound for our cars?

 

I was searching for some berks a while back so that's a yes from me.

 

I'm interested!

 

I'm interested as stated as long as I have my car

 

and here's a quick link to AAM's website in case you want to check out the company - http://aamcompetition.com/

 

count me in

 

I'm in.

i contacted them a while back to to make something like the short tails for a 370z (back then i thought those would make my car sound more like a 350z or 370z) they said they would help me fabricate one but i am no where near their shop so i was unable to do this

 

Yeah I'm interested

 

Sounds good to me...

 

Definitely Interested.

Also I see then Tune GTR's and 370's. Any possibilities they can tune our cars?
I find it hard to believe people can tune either of the more technological cars listed above but not a simple CVT with an old 350Z motor.

 

Nobody said the 7th gen can't be tuned, Uprev has a dyno tune available for us (can't get Standard, have to get Tuner edition and have it done by a shop or someone skilled with tuning).

Several people I know have an Uprev tune, including one guy who already has custom HFC's welded on and his car he says drives like a beast now.

Okay, since there is apparently enough interest check out the official group buy thread and sign up - http://my7thgen.org/f216/aam-competi...group-buy-931/

 

i wanna get in on this so bad, im seriously missing the torque of a V8 (and a FI V8 for that matter), but the money just isnt there for me right now. I hope this gets going as when funds are available, id love to have this, especially now that i learned about this Uprev tune.

 

Unfortunately only a few people have actually signed up so it's still not certain if this part will be made. Looks like a lot of interest here but not many willing to actually follow through...unfortunately this is exactly why companies don't make parts for Maximas...

 

I would love to have HFC's but not having a readley available tune to realize the true ROI is tough.
It's kind of a catch 22 situation with this car. You need people to step up to be investors in something they are not sure what the true results will be, but in this economy it's often the only way to get these parts marketable.

 

why does everyone keep saying you can't tune this car? I know several people with Uprev tunes. it is exactly what I'll be getting after the HFC's are installed

http://forums.maxima.org/7th-generat...ing-tuned.html

 

Ghozt, I did not say you cannot get a tune for this car. Please go to UPREV after your HFC's are installed and get your tune.
Please report back with the dyno numbers, the cost of the HFC's and the type and cost of the tune.
I will then try and determine if a "return on investment" was realized.

 

Ah my fault then for misunderstanding. Est. price for HFC's is 350-400 (coming from AAM), price for Tuner edition Uprev dyno tune is 650 (looking at getting into a group buy with National G Club to save some). Dyno tune results will vary from car to car depending on the mods you have.

And yeah because this isn't a "performance" car manufacturers realize sales will be limited with performance parts, but if they can't get even a couple people to say they want the part I don't blame them for not wanting to spend the R&D to bring it to market. For me personally it is frustrating and many of you know I've always worked to bring new parts to the Maxima if I can help.

 

I'm with you on that Ghozt.
If I were to go to my local UPREV what would I exactly ask for regarding a tune for this car, Is the OSIRIS program available for the 7th? I know there have been a few people as you mention that have had tunes performed. I didn't think it was something my local UPREV tech would know how to perform without having to inquire with other tuner shops (eastcoast). In other words it's doesn't seem to be a
"tribal knowledge" thing yet with all the UPREV shops. The 7th Max isn't a vehicle advertised on their website for this type of service (last time I looked anyway).
Please correct me if I'm wrong but I'm seeing this as more of a custom tune for the 7th gen.

 

Cost of the HFC's are a bit steep for me exactly right now being unemployed, if this is available later on i would shed the cash without a doubt. I will def stay tuned in though.
Another point is if you don't want to spend a few bills for performance then you need to stay away from mods nothing is or comes cheap around this part of the site.

 

Correct it is a complete custom tune. I tried to get the Osiris Standard and it isn't available for our cars so you can't do the mail-in tune. You're probably right that not all Uprev tuners know how to dyno tune the CVT, if they want help have them contact Hills Garage here in MD.

If we can get enough interest they'll definitely be available later. This is one of those mods for the power-hungry like me.

 

Does anyone have a picture of the exhaust system under the car, particularly near the pre-cats? AAM is trying to get an idea of what the OEM cats look like so there are no surprises when I loan them my car. if anyone has pics of the exhaust system near the pre-cats, the pre-cats themselves, or has a lift and can go take one that'd be very helpful. I'm working on getting a pic too

 

I am down to get some HFC as long as the gains are worth the $. I will keep an eye open for updates.

 

Forget this is just do no cat just header back to a muffler free flow you'll throw a code but its watever much cheaper and put it on a dyno and see what the difference are if there extreme differences then make a HFC done deal

 

^ lol trust me ive debated the other options: just a hammered out CAT, a cut-out, straight pipes. you're right that we'd see more power from no cat, but I want to try to help bring a new CEL-free bolt-on performance part to the community. we certainly dont have enough options as is

 

Sounds like a fantastic upgrade but I will have to add this to my wish list, I am still trying to pay the car off not to mention I just inherited an FX50S

 

Let me save you guys $500-600 and get more power then HFC.
Gut your stock Exhaust manifold and put o2 extensions....BANG. $100 later

That just doesnt make sense to me for 8 HP and 14tq for that do headers.

no hacking required all you gotta do is unbolt your OEM cats remove the cat and bolt it back on.....you could do this in your driveway.
you keep your resonator or add a high flow resonator you wont get "high off gas fumes"

$600 for 5HP is the stupidest thing in the world to me. for that just get a UPREV u get 10+

$600 HFC + install $300 = $900 later and i still have the fastest all motor 7th gen.

add the BOPs and you will get 6hp with -6tq!


Why dont you guys go ask Racingline performance why they dont have the HFC anymore for the 08+ Altima which have the same engine as our car does. Its not WORTH It you dont even feel the power.

 

Nevermind, we got the pics we need. I'll keep you all updated with the progress when AAM takes my car.

 

count me in too! jsut as long as no lights come on im all for it Ghozt..

 

Yeah these will be direct bolt-on, no CEL's.

Like with mod exhaust mods, you can hit up an exhaust shop and get something custom-welded for less or buy a bolt-on solution which can be easily taken back off.

My buddy has a shop that wants to weld on custom HFC's for pretty cheap as well but we all know we need more real bolt-on performance parts for this car so why not do this right. I'm not personally interested in hacking up my exhaust system, if I was I'd just run test pipes and a cut-out and while I drive get high off the exhaust fumes in the cabin.

 

I hadn't heard an update from AAM for a while, so I went ahead and contacted them to see what was going on. They let me know that they lost 3 welders in the past month and no longer have the time/staffing to pursue a new project.

If anyone knows any local custom exhaust shops that know how to make and use a jig and has some time, I'm sure we can get these HFC's made this isn't rocket science, just right now nobody wants to spend the time developing a part that looks like it will only sell 5 of.

 

oh no doubt count me in bro..

 

wish I could man. right now the plan for AAM to do them is shelved, they're too busy. another member has some custom made and is looking into having bolt-ons custom made after his guy makes a jig to get the right angles and gets the right flanges.
