I love my ART pipes and TDX shockwave.

 

Bump

Knowledge is power, even more so going this route.

Parts along with doing mostly all the installs, and a one hell of a tune. I came short of $3500.

With tunes/dyno pulls/muffler shop tweeks. I ended at a healthy $1000 shy of the Ops final bill. Plus I paid too Goddamn much for shipping.

About $10k I got this on a dyno dynamics at Dynosty and a 12.2sec @124mph last year on a stock clutch and block. I'll be going back to the drag strip soon to get back on that Top 25 TT 1/4 mile list with a new tripple disc clutch from OS Giken

 

I'm surprised the stock clutch has been taking that abuse at the track. How much boost are you running 7-8 psi?

Triple disk clutch a little overkill? Unless, you plan to build your block and up the boost? I plan to purchase a giken twin disk setup but I don't ever plan togo above 500-525 whp.

 

I picked up 25 RWHP on an Uprev tune and ARK cat back exhaust. The dyno graphs on the original run showed REALLY rich and once leaned out to a respectable mixture the numbers were there.

So i am $1,300 in total (700 for exhaust bought on discount offer and 600 for the tune), and the car really feels the difference, particularly in the throttle response. Next up will be HFC and headers (someone else at the shop had only that difference and was making an additional 25rwhp above me. Dyno attached not of the stock runs but of the runs where the tuning was done once exhaust was installed, pre and post tune. (BTW this is on a dynamics dyno, usually read low).

 

i dont understand why someone would tune their car after cat back exhaust even though they know their gonna add more NA parts. kinda dumb

 

Try driving a z with a catback and not tune, then come talk to me a-hole. Car was terrible, and I had no plans at the time to add the HFC and Headers within the year. I have since changed my mind, and will gladly pay again for a tune. Compared to what I spend on my other car or even some of these guys with their turbo's, $600 a pop for one of the best mods out there is well worth it, even twice a year. I paid 600 for a single plan intake on my triumph and after tuning only picked up 10 peak hp, with a loss of about 4lbs pk tq. That same $600 saw a much better gain on this Z, even if it is only for a few months.

 

When you first buy the UpRev software/agreement/tune it's $700 but each additional dyno tune runs around $250-$300. So it's not that big of a hit. I have had my car tuned twice! I'm going to have another Tuner, check my tune next week at my usual shop. See if there is anymore power to be unlocked.

a triumph owner hmm typical attitude. Also a ARK exhaust owner..... Uhh yea your def right iv NEVER driven my Z with exhaust and no tune

 

Yes, I actually own two triumph TR8's (direct links to my albums for each are below, along with a few direct pictures), my convertible which has about $28k invested into it and my coupe, which is now broaching $35k (and is my personal favorite). Not sure why that is relevant but apparently it is? And yes, I bough the ARK exhaust system, installed it myself (helps when you own a lift) and I can't say anything but good things about it. It can get a bit loud if driven for 2+ hours at a time, however I don't drive often due to work travel, so it's not a huge issue for me. The exhaust bolted right on, fit and finish were great, and it was actually harder to get the ORIGINAL exhaust off then get the ARK one on. Again, I do not see the relevance for this either in your statement above?

2004Black350Z is an ***, but he is right lol. A cat-back exhaust on an otherwise stock Z shouldn't affect the driveability at all. From my experiences, HR's come kind of rich from the factory.. so most of your power came from the tune. In other words, the catback isn't what caused your car to run rich (if it even was.. sniffers are pretty worthless when it comes to reading AFR's thorugh cats...).

So how do you know you got 25 wheel from exhaust and tune? I see that you got 16 from the tune, which is very nice.. oddly nice in fact. Do you have a bone stock dyno?

Something fishy is going on here though.. there is no way you're going to get another 25 rwhp from headers and HFC.. they're both practically worthless on HR Z's. There is no way some dude picked up 50 rwhp from exhaust and a tune LOL, especially if he has HFC!!

 

I will say this, 30-40 plus tune can be had on a HR with bolt-ons. Getting a dyno to show this, weather/humdity plays a HUGE ******* factor.

A certain HR with Injen short-rams/true duals from the catbacks made 298-300whp on the same dyno I made 277whp with Injen longtube intakes/AAM full exhaust. Now the only difference is the weather.

******* weather!

For the same reason you can trap a 12.9/108 =/- in a cold snap....

a little sour from my recent pull but I blame weather!

:sad:

 

Where are you dynoing and on what kind of dyno? A good dyno / shop with SAE correcting should negate weather changes down to a few ponies at most..

At least my shops numbers always seem to be very consistent regardless of the weather over the more than a few times I've dynod there and dyno days.

 

You're right, I don't have a stock dyno pull, just going off of the 'supposed' theory of 240rwhp on a dynamics dyno. That being said, i know of a few others (amirz i believe as one?) who, on the same type of dyno, saw 295rwhp - 30hp gain over me, only difference was headers and cats. I would think, looking at them, that headers would make a big impact on this system.... however, different dynos, different days, etc., i know all that, however I do feel that the gains are there.

The car still drove with the new catback, however there was a noticeable decrease in throttle response. very noticeable, particularly in the lower rpms. this is usually common when going from a 2-1 exhaust system to a td 2-2, you tend to lose lower tq but make up for it in peak hp. I never said it wasn't driveable, however it was not enjoyable to drive.

The more I drive this car the more I enjoy it, and the reason for the headers, hfc, etc is because I would like to see if I could get 330+ rwhp out of a N/A stock internals 3.5HR. Not sure if it is possible, but the more I think about it the more I sway myself to pursue it...

 

Well let me just say.. do a little research around here lol. On the HR Z's the headers are already damn good, basically equilegth in fact. And HFC's don't make a ton of power either, our cats aren't bad. Test pipes, or even better, ART Pipes, will give the best N/A gains, but come with a lot of noise. 300 whp is about as high as you can get, depending on the dyno of course.

GL and enjoy her!

 

I wouldn't be bustin on British cars! I grew up with an Austin Healey 3000 and a '66 Triumph TR4a. Alot of great memories with both cars!..
Healey's are no slumps. Triumph had dual weber carbs with an overdrive conversion.

Ignorance is not Bliss for you 2004Black350z!

I wonder if the rest of this thread is as funny as this page lol. Tuning after adding just an exhaust is stupid plain and simple.

 

AJ, I know you probably do alot of racing with your 14 second car, however please allow my humble self to impart a few words of wisdom - anytime you change a part that will directly affect the amount of gas coming in or air going out, a tune will optimize the performance gains of said part and can never be a 'dumb' idea. Now, on my dyno (posted below) you can see how just the tune made a significant difference, particularly on the curve, with ONLY an exhaust. not only that, but it did make an impact on the throttle response as well.

TR4a - classic british car, best lines of the marque....

 

LMAO everytime somebody refers to my sig it makes my day. Guess what a tune will make power on a stock motor. Doing it before your done with all your N/A mods is stupid like I said. Why pay $400 then add something and pay $400 again??

 

I wonder if you would be within 200' of AJ at the end of the 1/4mi....
