Well here is an update on what I was up to for the last two/three years sorry I have neglected this forum for a while, so he is what the Z has been up to just took all of the stuff from my local ChicagoZ forum that I posted.
Enjoy.

I figured I would make a thread on my progress on modding my car to keep it all in one place.
I went to Sound Performance on Sept. 20 to get a baseline dyno done. My car STOCK put down 283whp on a Mustang Dyno, Which I am very pleased with :)
That night I put on Berk Test Pipes and ARK True Dual exhaust. Both parts were made with great quality, But...
After the install I started the car and let me just say it sounded amazing!! But then it started... There was a very high pitched whistle/humming/hissing noise from 3.5k-2.5k rpm's on deceleration. I kept it on the lift and had a co-worker check it out this is what we found.
Due to the increased Exhaust Flow because of the Berk Test Pipes the Xpipe which is on the ARK exhaust system created a wild loud howling whistle. After contacting the ARK they agreed with my conclusion, I am going to send back the exhaust or sell it.
The exhaust sounds great without test pipes or HFCs but im going to keep my Test Pipes installed especially after tackling the "Demon Bolt". which I killed in an hours time for removal of stock cats and installing the test pipes.

Here are some pictures of the install, The new Exhaust I am planning on getting is HKS High Power it is a very similar set up to the ARK but incorporates a "H" pipe rather than a "X" pipe
I am also planning on doing Dynos after installing the new exhaust just waiting on some companies to get back to me.

This is a Stock exhaust on a cold start with some rev's to 4k

Just got back from THMotorsports, Lets just say the HKS Hi-Power Exhaust Looks amazing I will be putting it on later this week then going to Sound Performance soon after for a dyno, then taking it to Byron later this month :)
Here are some pictures of the New"er" exhaust :)

DAN





Just installed the HKS Exhaust system, Lets just say the Fit and Finish of this product is second to none!
All of the flanges bolted up square, All of the welds were solid, and the adjustable tips are very usefull.
I cant wait to get back to Sound Performance and see what the gain is with the Berk Test Pipes and HKS exhaust
Here is a video clip, Play this on a good speaker set up otherwise its not doing the exhaust justice. There is a little hint of a Hiss in person and for some reason its amplified by the video, But under load there is no trace of it.
Enjoy

Here you go enjoy!

Well, I went to Sound Performance today to get a dyno to see the results of my exhaust bolt-ons/ Berk Test Pipes and HKS Hi-Power Exhaust.... Lets just say I am very very pleased :)
Remember my Baseline dyno results were very good 282whp were the results on my Stock 09 370Z 7AT...... Now I am making 304WHP that is a gain of 22WHP from Berk Test Pipes and HKS Exhaust!! I am a very happy guy :)
Below is a picture of the Dyno sheet with baseline so you can see how the mods gained HP throughout the entire RPM range. Also there is a link to a video of one of my three runs.
Also I went and had a little photoshoot with Blackie once he is done going through the photos he should be posting them for me, Thanks again Young!

Well I went to the track to day (Byron Dragway) lets just say it was a little brisk out. The temp was 32 deg when I pulled into the track, They didnt even finish getting the track ready until 11:00AM.
So as you can imagine the track was very slick, seeing how the high temp of the day only reached 45..
The total amount of runs that I had today was around 15, most of them were failed passes due to a bad launch because of how cold the track was or spinning tires from 2nd gear to 3rd again because of how cold the track was.. well most of the runs were low 13's very low, 5 of my runs were 13.2 or lower and I have the slips to prove them.....
But the most interesting time was a 12.9 run! Yes that is right a 12.9 run with exhaust bolt-ons and stock tires! Here is the slip of proof and I even bounced the rev limiter from 3rd to 4th gear, I could have reached a quicker time!
So I say today was a win for me a 12.9 Pass with street tires minimal bolt-ons and a very slick track :)
Enjoy the pics :)

Just and update, I will post pictures of parts as they come in and as always show the results with dyno #'s
I just ordered Stance GR+ Coilovers and SPC Camber Arms, GTM Comp Oil Cooler 25 row Setrab (due to GTM Super Charger kit in the future), Fast Intentions Long Tube Headers, and I will have the car tuned with UpRev.
I cant wait to get this stuff here and installed! I was really wanting to get the GTM Stage 1 Supercharger kit but that will have to wait until next spring :)

Picked up some of my parts today from THMotorsports and Touge Factory (Had to bust out my Skinny Jeans for that one) Stance GR+ Coilovers and SPC Front and Rear Camber Arms is what I got, Still waiting on the Long Tube Headers from FI ETA is at the end of March, also there is a Custom Oil Cooler from GTM on the way. Here are some pictures of the Stance and SPC parts.

Fedex dropped this off today!

GTM Oil Cooler -25 Row-

My Fast Intentions Long Tube Headers came in today, and I must say the quality is amazing! I cant wait to hear them paired to my HKS Exhaust :) Here are some quick pictures

Update on the Z

Well as most of you know I got the car back from Sound Performance, Lets just say I am in love :) From the new stance of the car thanks to a set of Stance USA GR+ Coilovers to the new Exhaust tone that has actually been cleaned up (most of the rasp went away) with a set of Fast Intentions Long Tube Headers (with header wrap got to keep the temps down) I will post some profile pictures to show the drop which is about an inch up front and 3/4's of an inch in the rear... and also a video of the exhaust. Other parts that were installed are SPC front and rear camber kit which allowed me to stay within stock camber specs.... and GTM 25 Row oil cooler which during the meet/cruise on mothers day I saw a high temp of 190 :) seems like its working great!

Just got back from Project X, I must say the car pulls alot stronger throughout the entire RPM range, on the dyno that Project X has access to which is a Dyno Dynamics my car made a baseline of 261whp 205tq after the tune it went 268whp 210tq so needless to say I think the UpRev was worth it. Also had the idle raised a bit and the redline raised 200rpms, and the valet mode.

I just need to get back to SP and use their dyno which is the one where I did my original baseline and bolt-on dynos... Im sure since my last dyno there was 304whp and now that I have the long tube headers and a tune it should be 315whp on the mustang dyno.




I will post the Project X dyno graph when I get a chance... Also an updated video on the exhaust note

In Final post above that was last spring car ran great all summer took it to Branson Z fest last year had a great time, only thing is I have to get the rear coilover checked out it is making a clunking noise when hitting a mild bump I already looked at it myself and couldnt determine what the issue is so later this summer I am going to try to get back to Sound Performance and have them take a peek.


Also here is some updated shots of the Z took these a few weekends ago at a local state park, just breaking in the new ADO8's those tires are sticky!

Thanks!

I think my next mod is to finish paying it off ha, Other than that I will try to make a decision on some wheels or maybe a decent power adder SC kit or N20.

Nice build, you put on all the right stuff. BoostPerformance makes an excellent twin scroll turbo. Currently only making them for your car, I have been buggin him to make one for AT. No luck yet..

What kits have been thinking of ? Just curious.
