If the Ark exhaust was that much better than the FI system, no one would buy FI. That doesn't make sense to me.

I'd like to see what you guys would get on mcnews mustang dyno. Would be interesting for sure

I have a bumper mounted GoPro I'm anxious to test out.

I understand that, but I'm just telling you not to get your hopes up. Momentums are shorty headers so granted there was reason to doubt them... I still am not sure exactly why they supposedly make so much more, when compared to our parts. But I'm not a fan of using parts from another motor on mine, that's just me.

I hope you DO tag 330 because it might help give light to my problem. But as of yet, I don't think anyone with any setup and the headers has hit 300, and I have every bolt on you can do besides the motordyne manifuld which is a joke/ripoff.

Its really because FI has a lot of hype. Ask a lot of the people who have an ark. They wouldn't trade it for anything. Personally the sound is just better to me. not even the sound as a whole. Little things like flutters on down shifts and the sound when the flood gates open at 4k. FI is great they make really good stuff hence me having their headers. I just think the Ark is the better exhaust mostly because of x pipe placement

So my 324 on a mustang is low?!?!

Insta-boner!!!!!

The answer is: Test pipes.

lol

My previous Dyno's were on a Mustang.

And with K&N Drop Ins, MAF Tubes, Headers and CBE, and Pulleys, I did 284whp with no tune.

They make power because of the collector they run. It flows better with less turbulence. Also why the Ark is so good. That x pipe placement is perfect in stopping a lot of turbulence.

It was 324 on a DynoJet bud. :icon17: Not a mustang.

Then why haven't you gotten it tuned to see where you're at?

U just said aam has a awd mustang dyno

Eh. I dunno. I looked at both before I went with FI. Ark, FI and Stillen were the 3 I really looked at (Berk sounds awful and Meisterschaft was just too damn expensive). If you can show me empirical data somewhere that shows the Ark grip is superior to the FI, I'd be really surprised.

Edit: I mean, if you're right and the FI exhaust is "a lot of hype", there are other gearheads on the forum that would have ripped it to pieces by now...right?

Nope. I said a Mustang is the one that reads low. Just looked at my dyno sheet to double check, DynoJet.

:iagree: :ugh2:

That was the plan homie. Akumas +tune with vvel beta. But you know turbo. Why spend $1200 for all of that just to undo it in a few months?


Sadly the paperwork just doesn't exist. Once a trend starts it steam rolls. Everyone knows FI is proven and newcomers get on the forum and everyone crams it down their throats.

I'm not even saying FI is bad? I'm just saying its highly recommended so no one cares to try one off setups. FI is amazing and has proven results. Its a good exhaust system with great gains.

Ark really didn't do anything but ripoff the HKS design. Sorry to say... :ugh2:

I agree that there isn't much of a market for homemade stuff, but at the same time, most people who get a 30+k car don't wanna take it to bobs exhaust shop for a $150 exhaust... (not saying that's what you're doing, but just using it as reference)

I want you to hit 330, don't get me wrong. It will show me the reason I'm not is because something is wrong = needs fixing. Rather than "It's running fine, it just runs low" because right now that answer is not sitting well with me. Based on what I've seen with others, my numbers are low for a reason. And if you can tag it, it's possible.

Honestly tune is 600 and intakes are close to that as well. That's my $1200 haha.
Also no offense to AAM but they are GTR guys. I'd go to RAD or RT tuning for the tune.

And no I understand not everybody wants to do that with an exhaust. I just figured there would be more people willing to play with mixing the prefabbed parts is all. Idk were talking miniscule gains here but I truly believe that 330 would be obtainable. Too bad I has no proofs ):

Oh, ok, your number was all inclusive... I thought you meant 1200 just for the tune.

That is true, but I like to give them the benefit of the doubt that they know what they are doing.

The other guys RAD, and RT are so far away from me it would be a weekend trip, and I can't afford that plus I don't think they're open on weekends anyways? :icon17:

I'm not sure most people have the resources or desire to tackle that sort of thing... Too much measuring and cutting and welding, to need to remeasure, cut and weld, 5 more times... :icon17:

No doubt AAM is good I just see them having a lot more time on GTRs then the Z. Can't blame them GTRs kick ***. Haha.

And yeah i dont know shop hours. I think RT is partially open saturday and theyre close to me being out near philly.

Cutting and welding...Uhg such uhhh "fun" times.

I do notice a lean towards the GT-R side, I guess I was just hoping some of that GT-R experience would filter down to the Z's.

If I can't find resolution beforehand, I might take it to RT or PTuning later in the year for a second opinion. The fact I've asked for information and haven't gotten word back in over a week is not making me feel comfortable about it. :ugh2:


I'll have to look into RT, maybe we can work out something. I already have the UpRev license, so that cost should no longer be needed right, just dyno pulls?

Dude RT quoted me $400ish for an NA tune and $600ish for FI tune. Im sure it'll be less since you have uprev already. just email Erik@rttuning.com tell him I sent you. They have a lot of broad experience, lots of boosted stuff, A bunch of Zs, I even saw them post on instagram a McLaren MP4-12C they were tuning.

Sploosh!! :yum:


Wow, that's crazy... Gonna have to check in on that one day.

Haha my thoughts exactly. Mind was blown

Let me look up their website and see exactly how far away they are from me...

2wd dyno tuning: $200/hour... Hopefully since the hard work is done (initial tuning) I wouldn't need much work, perhaps troubleshooting/adjusting, so one hour would theoretically be enough for me... Might definitely want to give them a call... Hmmm just under 3 hours driving time, so roughly 2.5 hours for me.

Would have to be doing the tune in the afternoon... Gonna have to at least ask them about it.

Moore auto charged me about 400 for a NA license/tune.

Yeah they shouldn't charge you a whole lot. I cant say for sure but with other similar scenarios at other shops ive seen about 100-200 for this sort of thing.

They are about 2 hours from me so about the same. They may just have you datalog and then adjust it via etune. Probably don't even need the dyno really. I bet your fuel isn't trimmed right or something with the AFR's are off which is why you cut power up top. I don't know though im not a tuner.

i dont care what you duuudes say. I fricken love the ARK exhaust, rip off or not, its sexy as sh1t, and it sounds fricken awesome. Just saying.

Haha that's what Im saying. It sounds so good that I wouldn't care if I have 0 gains from it.

hahaha, hell when I got my tune done, the tech said I had very nice gains from the few mods that I've done..

and actually when I was dealing with my o2 sensor, I had to take the Z to an exhaust shop and they were ranting and raving about my exhaust.. they fricken loved it.

ok aside from all this wonderful tune talk are we still doing the judged show field right? i mean this is the thread for Carlisle and all lol

Did you register for judged?

i'm about to today or tomorrow. pre-reg is good til april 8th so i still got a couple days.

even though i'm pretty much stock i figured it would be cool to get to all park together in the show field.

:roflpuke2: So I'm not the only procrastinator, eh?

mine isnt so much procrastination it's more like i was on vacation and wasnt sure how much money i'd have left after it lol luckily i behaved and came home with some money :tup:

unlike our one friend who blew his all on the first night.....and then we had to split his golf, food, drinks, gas the rest of the trip between me and my other friend. that sucked.

Yeah I'm in the judged showfield. Not expecting to win anything but it's fun to park with all the other Zs.

Bad form, man. Lucky for him you guys pulled together.
That's what I figure. Maybe if I park next to you it'll help your odds - your car is pretty damn fancy compared to mine! :icon17:

he is just a degenerate gambler. we hit up a casino boat thing and he couldnt control himself next thing i know he's broke and drunk.

my car is completely stock looking lol only thing on mine that makes it seem like i modded it is the exhaust tips lol

:iagree: same here

Mine is completely stock, other than the tint. I've finally settled on an aftermarket exhaust system, but it's not one of the more visible setups so even if I get it installed before Carlisle it will still look pretty much stock. The only visible change I'm likely to make before then is installation of the carbon fiber B pillars - I bought the pry tool and plan to attempt replacement this weekend.
