Tune went well, cars running great numbers are a bit lower since i added the resonator 418whp and 365ftlbs torque at about 7.5 psi the tuner said his dyno usually makes lower numbers than others, but numbers aside it drives great i have been in friends 370"s and a g37 and you really notice the difference. i'm kinda just playing it safe for now but will probably bump up the boost in the spring. I couldn't be happier, zero regrets!

by any chance would this be a front mount single turbo set up getting produced next year? PM me if you can? I don't wanna get this thread off topic lol

Guess I was not very clear, I may be done with the Z and getting a BRZ or FR-S.

On topic: talked with STS Friday and currently the 7AT is not supported for their kit. The piping does not fit around the transmission. If that was already known sorry for double posting.

I am calling them again Monday to talk to one of the RnD guys to see where they are at with progress if any on making it work.

Awesome! Once your ready bump it up to 9 psi you should still be safe in that range :tup:
Also can you please get me a pic of the resonator?

Dammmmmm what a let down i too have a 7at and liked this kit cause I thought it would probably be the safest route to go with the auto tranny :eek: hope they do make it work

What do you mean by safest? If you are talking about engine longevity then you will find that the kit itself makes the least difference and the tune makes the most difference.

STS will work with the auto transmission. Should have an update later this week

What I like alot about the kit is with the turbo being at the rear of the car there is not too much extra heat being produced in the engine bay like a traditional turbo set up

Mine will be finished Monday or Tuesday of this week for a AT7 tranny. It took a little fabbing by the guys at Executive Performance in Meriam,Ks but looks great and as far as I know it will be the very first. I've driven manuals my whole life and other than a little lag between shifts it acts just like a manual. On top of that you can't out shift a computer. Once the methanol injection is complete it's off to the dyno. I hoping for something around 470 and up at 8psi.

an undertray would be a good idea, one of my guys had to have his exhaust housing welded it was starting to split

Which methanol injection system have you decided to go with and have you had any experience with it in the past?

Still waiting
 

It's the methanol with boost controller kit that STS sells and no this will be my first. I was a Ford Mustang man my whole life until a year ago I bought my first 350z. I must say this has been the worst 6 month project of my life. I know and understand STS has never done one and when their own guy says it should of not be realeased yet, it makes me worry. They have done everthing to fix the missing pieces, wrong pieces, etc but first dyno we could only pull 390.37hp with 340.77lbs torque. Hell at 5psi it was only 322.22hp with 273.65 torque. Oh did I mention they sent the wrong sprayers for the methanol injection and sent a 2 gallon jug. Now where in the hell is a 2 gallon jug gonna go in a 370?? Next Monday it's going back in again. Project started in June....

Sorry to hear that you've had problems. I also got very close numbers to you around 415hp 365lb torque at 7.5 psi I am hoping to add methanol injection and bump up the boost in spring. I don't think i'm gonna go with their kit though and I was thinking of building a custom tank in the trunk because as you mentioned there just isn't much room in our car for any of the pre-made tanks. I had recieved a dyno chart from sts with higher initial numbers but then i added a resonator it seems to have dropped the numbers a bit. Are you running a resonator on your setup? And do you have hfc's or test pipes? I hope you get your problems resolved quickly, I am curious as to whether you feel the methanol injection is worth it.

Is that the highest numbers you've seen and which dyno? On the sts site it says it's good for 470whp @ 7psi

The site is quoting estimated Brake HP, not Wheel HP. So 470 - 15% drivetrain loss = around 400 Whp.

Rick had sent me your dyno sheet while mine was being installed and I seen max was 456.8hp or he sent me someones elses but said it was from the first one they had done and it was rolling around in Canada.
Was told they talked to the guys with STS and they said there should be no problems hitting the 450-470 range, but yet again I'm the guinea pig. They have never installed a methanol injection system on a 370z. I was told the spayers they sent were for a V-8 so they sent a pair since it needs to hit both side of the engine. I'm hoping that by tuesday I will have the final numbers. So far $11,000 for 92hp...damn I got screwed

You mean 192 hp?

Yeah that was my dyno sheet before I had the resonator installed, wow that's a lot of coin, is a lot of that install costs? I sincerely hope that your end results are worth it. I was supposed to get their methanol kit when they were installing my turbo but paths got crossed and it didn't happen, by the sounds of it maybe it's a good thing. I have all the parts for the snow performance methanol kit I just have to make a tank for the trunk. Who is doing your install? And where are they mounting your tank?

Also I'm pretty sure the dyno numbers he sent you had been corrected to sea level, I don't know what elevation your at but that can be a bit misleading as well. How much boost are you planning to run when the metabolism injection gets installed?

No, the site clearly says whp...

"A combination of our patented remote-mount technology combined with an intercooler provides the lowest consistent air intake temperatures over any other forced induction system on the market. Owners of otherwise stock vehicles will experience 470whp @ 7 pounds of boost, but also receive the benefit of increased fuel economy over the competition. The beautifully tuned exhaust note from an STS Remote-Mount Turbo System is sure to put a grin on your face as you flyby all those other imports."

I'm at about 700-900ft and I'm shooting for at least 8psi and at higher elevation your car can't breathe as well. I had just gotten back from working in Wyoming and my work truck was acting like it smoked 10 packs of cigarettes a day. So I know at my elevations I should see better numbers.
It's the guys at executive performance in Meriam,KS they were the only ones with 2 states that were STS certified. The main cost was I got the ball bearing upgrade, coated turbo, oil cooler, boost controller with methanol injection, & gauges. They only charged me $1200 for the install but for all the problems that this build has given them I threw them an extra $500 for the fact that they have tried to keep me happy and the quality on the worked done.

No the initial dyno was around 298hp, but the it was also being done in a hurry since they still had to finish the methanol.

We shall see. They also posted that with the methanol injection system you should see up a 100hp increase but that was also on a Z06 corvette. So far I've read a lot and seen a ton of dyno sheets but I'm from the "Show-Me" state. I won't believe it until I see those kinds of numbers.

Exactly I want to see it before I believe it or spend thousands on it. That's just a quote I took from their site, I'd really like to see some graphs.

I will try to post the specs by Tuesday or Wednesday by the latest. Taking it to the drag strip on Wednesday to see what it will do in to 1/4mile.

Excited to see your numbers.

Not bad number for AT7 tranny
 

Well the methanol is being used to only cool the engine. So it's not creating that much horepower because the tank is small and if I try to use for HP I will have to always keep an eye on it or it will do damage to your engine. Better safe than sorry. The numbers right now are @ 5psi 403hp and @ 8psi it's 438hp but he left the rain sock on the air filter so there is another 5-10 more hp and STS has a new cable to tune it in while it's on the dyno. So that being said one last try in 2 weeks but right now it's breaking loose when I punch it through 4th. I will try to upload the photos tomorrow(dyno sheet).
This is just the start for her...looking into bumping it up from the 3700cc to a 4150cc...another $2300 plus labor.

Sounds like your having fun how does it sound?

Loud....Very Loud. To the point of when the BOV's go off people on the sidewalks jump and look around like someone had takin a shot at them. Sounds great going under bridges or through tunnels. I've gotten some many thumbs up and people taking either pics or videos since it was installed.

Videos are a must man, post them up!

Any updates?

i just want ONE decent video online of this system outside the car. SOMEBODY please just post one

If I could ever get the guys who installed mine I would but it's been like pulling teeth and I've got a misfire on cylinder 1 but he said it was the coil pack.

We have a STS car we are building . I will post videos soon

So I take it your luck with this kit has not been good?

It was at the start since it was the very first STS AT7 370z. They had never thought someone would throw a turbo on a automatic. So the guys here had to design an install a system never done before. There wasn't to many things different except the tranny is about twice the size of a manual. All in all I'm happy and when someone with a GT tries to race me I simple make the turbo "laugh" at them and then they back off and want no part of my little V6...:happydance:

got a lil vid tonight when tower gave me a demo of this sts system. not very long, but kinda gives u a good idea of what this thing runs like. i must say i was VERY impressed with how well these things run on just 8psi. its pretty amazing how hard it pulled.

now i must get one!!!

sts turbo 370z highway pull (inside car) - YouTube

Just image if it was cold....That was a warm run.

Cool vid but I definitely want to see a high quality vid from the outside. Are you running stock cats/tp's/hfc's and did you add a resonator?

It was one of those last minute things and traffic was heavy that night on I70. All stock...well except what STS had sent with the kit ( plugs and new injectors) and no resonator. The only thing I have done to that car was the turbo. The rest will come with time and money.
