In any car when you are sitting at idle no matter where is the air filter located, The AIT will rise sense the MAF tubes are are also in the engine compartment, our testing shows no real disadvantage of having the filter there, also the keep in mind that the factory manifolds s are very well insulated. all the AIT sensor we placed at the IC inlet ,IC outlet and At the MAF sensors showed identical reading just like the stage one kit where is the filter is located in the Bumper of the car.

I have seen and experienced factory cats lasting over 70k, of course there is many variables that will effect that. As for the radiator, We will offer 4 version:

-One that will be only bigger radiator that will expect the factory fans and another One that will have internal heat exchanger built in that can be used for engine oil or trans oil cooling

-The other two models will have the Spal HD 2400 CFM fans that can plug to a fan controller so you can control when the fans will come on and off, Of course with and without the heat exchanger option .

So us Stage 1 guys are making like ~400-430whp and something like 320-340tq. :( Stage2 gets a big bump in HP but only seeing a small bump in tq numbers, 365 and 350 on the first 2 dyno's. Is that to be expected with an SC setup or is that just with our cars in general?

Also, any word on an upgrade path from Stage1 yet Sam?
Generally Sc cars have lower torque numbers then twin turbo cars, The stage 2 can do 400 RWTQ but you will have to spin it faster, so defiantly there is room for expansion .

As for the stage 1 Kit upgrades, We just need to finalize the pricing. We will have two options to offer, one option will offer a compressor housing/ intake upgrade and the other will be upgrading the charger to the 91 trim.

Here is some pics

Otherwise awesome, and extremely technical write up. :tup:

A lot of good builds here.
We are not saying that we are 100 % certain that the LTH's wont fit, Based on what we know we think they wont. So until somebody really try to do it we wont know. I think We have said the same thing a million time so far.

Thank you

Sam

SAM@GTM 09-14-2011 02:27 AM
Thank you everyone for all the kind words, We really appreciate it . Will be adding couple videos in the next few days, So stay tuned .

Sam

Sam not sure if you want to do this or not. But I would be willing to lend you guys my LTH's to test fit. Let me know if you want to

Mkai0 09-14-2011 04:00 AM
Awesome Sam, you know I'll be ready for the Stage 2 Upgrade! :tup:

You guys have done a great job at everything you guys do. What I like is the attention to detail and how you guys do not rush to put out a product. :tup:

I do have a few more questions about the radiator setup. I am sorry for asking the questions if they have already been answered.

What kind of results have you guys gotten with the new radiator setup? Will you guys be making a new thread to present the radiator as a new option to oil cooling? Also what kind of pricing should we expect?

i mentioned the air filter location on page one. does anyone else think its in a water prone area being so low? granted im not looking to go snorkling in my Z, but when it rains here (when it rains!) its bad!

SPOHN 09-14-2011 01:50 PM
Now I can't wait for the press release on the radiators.

It looks like it may be above the splash guard so unless you submerge your car I would think you would be OK. Maybe someone with the kit or Sam can chime in.

I have the stg 1 kit on my G. the air intake is in the fake break duck behind the trans cooler on my car. this is a low location.

1) I drive my car as a DD in rain snow and everything. Not one issue with water in 1.5 years with the kit. Now will i drive threw 2' of standing water? NO. But i would not have done that with the car when it was stock so no issue for me.


2) cuz i know it will be asked. No the trans cooler infront of the intake does not hamper the cold air going into the intake. it is only a trans cooler people not a blow tourch.

Would there be any point to a larger radiator if the OEM fans dont come on until 215*F anyways?

Any info on pricing for the upgraded radiator and the version with the fans?

37Z 09-14-2011 06:41 PM
Intake
 
Like the intake in your avatar! Are the intake horns' length adjustable?

theaudir8fan 09-15-2011 09:29 AM
The air filter is located pretty low, but i doubt it is any lower then the injen long tube cold air intake. altho with the horizontal placement of the filter, there might be a bigger chance of it getting wet. Physically the filter sits right above the frame, pretty much right beside the cat and is clearly visible thru the passenger side rim.
As for if it will take in water, we will have to wait and see, i'm the one that will be doing most of the cold weather testing for this kit.

Of course. Bigger radiator means more heat capacity through the combination of more surface area and more coolant capacity. Even with the fans set the same, a bigger radiator should do a better job of handling the heat load when pushing the car. It probably would have little to no effect on idling or mild driving around town, but that's not where people are running into trouble anyway.

'10Anamoly 09-15-2011 12:46 PM
Since the fans and radiator were in this press release, do they have pricing and an availability date?

Don't think so. Sam has indicated that that information is coming. There are going to be 4 different options.

dnasty370z 09-15-2011 07:24 PM
dam sam I've been really wanting to pull the trigger on on a force induction kit I just do not know which one yet but man you got me freakin out now because i have a 7at I am just wondering what do you suggest for an auto s/c or tt? and I would like to keep the car like that for some years to come do you think a tranny cooler, VB and torque converter would be help make the tranny last say 3-4 years im a pretty careful driver and only race at the track and I use the paddles on the daily Ive been downshifting before i step on it just to get used to driving like that lol Can you give me your opinion?

Jordo! 09-15-2011 09:43 PM
Wow!

Sam -- amazing stuff and very reasonable pricing.

Thanks also for providing details (and solutions!) regarding the extra precautions needed for boosted AT and also for your commentary on the underdrive pulleys.

Argh... now I just need a bag of cash... very much miss FI...

ZSIZZLE 09-16-2011 08:58 AM
seems like a great kit!!

I've been driving stick since I received my license 10 years ago. If any one of you guys are like me, driving manual isn't an issue in stop and go traffic. It's just that I am so used to it that it is like walking...

I could understand that, I never had an experience like this, or a father/uncle/older brother that had one I could learn/practice on. And I don't feel comfortable driving someone elses car because I don't wanna damage it lol So I just never had a chance to learn young which is when you should... just like swimming haha. :icon17:

wstar 09-16-2011 01:30 PM
I learned to drive on a stick (an older BMW 3-series), then my first car was an auto ('81 Firebird, which is the last year of the 70's-looking ones), which I drove for about 4-5 years. Then I drove a 6-speed LS1 car for about a decade (1999-2009, RIP my old WS6 Trans Am), and now I'm in the 7AT 370Z.

The 6 speed was a lot of fun to learn things on (e.g. how to double clutch, how to heel-toe (which I was never very good at)), and having spent 10 years on a 6 speed put me in the frame of mind to never really drive my 7AT in D-mode much, but the clutch gets old anywhere but the track, and even there I'd really just rather not screw with it if I can. There's a bit of adjustment from a manual to a paddle-shifting auto though. e.g. your instincts from the manual about when to drop off the gas a bit as you upshift are all timed wrong, but once you get used to it it's a lot of fun to drive.

Someday when I'm richer, I'll have a Porsche with a PDK, best of all worlds :)

Not hating at all. Nothing wrong with an auto. I have driven autos before and my SUV is an auto. I am just curious because I think it's odd to buy a pure sports car in auto, and I see a LOT of auto 370Zs both on here and during my tortured search for a car to buy. I know these new gearboxes (e.g. GTR) are faster, more precise, etc, etc, as compared to the old 6MT, and you can never make a mistake, but where's the fun in that? It's like bowling with the bumpers out.

Anyway, my bad for getting way off topic. This thread is about GTM's badass new stage 2 kit!

Hey, cool video man! That's my home track. I used to run my M3 and STi out there, and my brother ran his C6 and now his E90 M3 out there. Not sure if you're driving both cars, but you gotta attack that hill harder and not let off so early on the back straight, haha. I used to hit 140ish on the back straight in my STi running clockwise.

wstar 09-16-2011 04:50 PM
Yeah I'm still learning the track, while simultaneously learning to drive on a road course. My first class isn't until early November, so for now I'm kinda winging it on my own and doubtlessly developing some bad habits. But mostly I'm going "easy" on a lot of the decels and turns because I'm not confident about where the limits are :)

You can still have the same fun as a manual, perhaps it might be easier to prevent engine/tranny damage. But then now how can you say a MT driver is better if he's blowing trannys...

To me its just less of a hassle to drive and I can focus more on enjoying the road/track. :tup:

Agreed, back to topic. :tup: :tiphat:

efuseakay 09-16-2011 07:21 PM
Sam. What's involved with upgrading the 7AT? Can you give us a general idea of what steps need to be taken etc.? Thanks!

RCZ 09-16-2011 07:26 PM
Holy ****, what a press release. Kit looks amazing!

dixon cider 09-16-2011 11:26 PM
I want one!! :drool:

axio 09-18-2011 02:05 AM
Drove down from the SF Bay Area to drop off the Z today to get this kit put on. Adding the oil cooler and a meth kit as well. I checked out the radiator Sam had in the shop and wow, it's much thicker than the wimpy stock one. Tried to convince the wife to let me get one but we just don't have the funds right now. It looks like a serious piece of good work though if you guys want to get it. Looks top notch.

Sam What available Upgrades are there for the 7AT now, not including the clutch packs that were mentioned in press release (still waiting on pricing btw!). Is there a torque converter out for our 7At trannys?

According to sam (when I spoke to him via phone) the valve body won't do much....
