You are referring to the updated items Sam is shipping to people?
Great, but people are still running this perfectly fine without these items. The updated pieces improve a already working system to make the SC setup better.

I have past over 3k miles on my kit and everything is working great. LTHs are still a toss up in the setup, but the original kit was not meant for LTHs directly. I am tempted to take them off for a week just to get a dyno run with how the original kit was designed so people keep trying to stir the pot can sit back down.

Why would you keep them on if they are costing you power?

Because a lot of the community would like to see if they can work with the GTM SC kit, I have the LTHs and a SC kit and do not mind testing the waters a bit. I still might be taking them off in the end, but who knows right now.

Man i really want to put my lth back on. Would be great if they woudl play nice with sams SC.

got to call sam tomorrow and order up that 8 psi pully.

What I meant was that Im not surprised that you don't want to give numbers yet because you have some loose ends to tie. Seems like a lot of you guys have some finishing touches to put on your kits. No problem with that, but why do all of you have to change your kit after getting it?

I'm tired of the whole Stillen/GTM bs and over it so its all the same to me, figure might as well be helpful. I dont think that you guys are not going to be able to run the LTHs on that size unit. You might be able to port it and port the plumbing to get a bit more flow out of it, but IMO its not going to be enough to really make use of those LTH. Seems to me that the stage 1 kit is designed to be a stage 1 kit...go figure?

I think some of you would be better off running the stock headers. Either way, best of luck to you GTM kit owners.

The kit is not changed it is the headers/cats people want to change.
That is part of modifying ones car though, you get product X and you want to try something new and different with it.

Thank you!!

It seems like theres a war going on between GTM SC owners and Stillen SC owners, both are hiding their flaws to show they're superior which in turn benefits the vendors and hurts the community. I really wished we were more honest with our reviews and less biased.

Oh agreed, but whats the point of waiting to post results of product X when you've made it into product Y by changing it. In other words, you dont want to post results of the original kit as it came, you're waiting until you change things?



Anyway, I understand what You mean... I've been scheming to get 8psi at 2500rpm all the way through to redline steady. Just don't know if its possible yet.

That is the reason I am tempted to just rip the LTHs off for the time and go with what the kit is meant to be. No hassles, no testing, it will just work.

Yeah definitely don't blame you. You always get to a point where you just want to be able to turn the car on and off and not worry about anything else.

Sam no one is hiding GTM flaws there are non. the kit preformes exactly as it was advertized. The only things that are changing is part to get the SC to work with after market parts that the kit was not designed for nor advertized it would work with.

would like to know what exactly you think us GTM guys are hiding? All my numbers are out there and can be seen. Nothing to hide I posted everything and answered all questions asked.



Dreamer DON'T TAKE THE LTH'S OFF. I really want this to work out screw what other think. I'll paypal you $5 to help out the development process.

I dont think I have once hid anything from anyone here...the truth is, the kit has not changed from X to Y. I actually asked to have the proto intake pipe sent to me but it was agreed that it takes a rediculous amount of time to re-produce them by hand. Hence why casting is such a cost effective solution. All thats being done is reducing the amount of material inside the pipe to be as effective as the ptype was. I could have been running my kit but fortunatly I have a spare car and I am waiting patiently.

If something significant was being changed I would have been one of the first to inform the community. But the truth is, not even Sam could have predicted the casting company to create such a problem for him. Design is the same, functionality should be the same, the only unfortunate thing is the wait...basically if the casting company didnt screw up their would have been alot more kits running around already.

Either way, i'm excited to finally be able to continue with the install and provide the info others have been waiting for...by the end of this week if all goes well.

So now we're not allowed to post in threads of things we don't have? Give it a break will you?

I understand about the castings Danny. **** happens sometimes that you cant control when you send parts out to get made, no matter how much you plan for it or how clear you are with instructions. People always seem to find a way to screw it up.

i dont own either kit but im leaning toward the GTM...seems like the only "issue" was some high boost taper which has been identified n resolved..Sams' advertised HP claims are also consistent with the product..seems like a no brainer to me.

I think the question is if we put a smaller pulley on the setup will the unit be out of its efficiency range? If yes, then the LTHs need to go with a larger unit, if no then we might be able to see some great power gains.

< ----- still waiting on a dyno of a bone stock 6speed 370z with GTM kit on 8psi with all numbers being disclosed including DA, type of Dyno, etc.


:(

should happen within a couple weeks..

thought the yellow Z in the press release was a stock 6 speed. was it not?

I like how everyone thinks Sam is scewing the dyno numbers. this aint true i was there for every dyno run.

Well, people always question shop dyno runs and will trust an end user result more just because they feel it is not be skewed at all.
Not saying GTM or even Stillen is doing this.

It makes no difference whether you were there or not. Its besides the point whether Sam is or isnt skewing the numbers. If the dyno had said 700hp when you were there, would you think your kit makes 700hp? No one is saying he is lying, its more of a matter of confirming what kits out in the wild are making.

FYI, just by the way you change the settings on the dyno you can make cars read a LOT higher than reality or lower for that matter, but you knew that.

Tell that to one of the shops here....:ugh2:
Will not go back to them now or use their dyno mainly.

Yeah man, we had a shop in Boston that would pump out miracle cars that always seemed to have "issues" when they tested on third party dynos. Always battling "leaks" and the like. The worst part is that you always get caught, whether its on another dyno or on the 1320.

Please STOP personally attacking other members. I don't care how good or bad your GTM or STILLEN SC kit, but I'm a little tired of members making fun of other members. As I always say, if you have something against another member here, TAKE it OUTSIDE the forum (via email, AIM, etc)

I'm not accusing Sam/GTM or doing anything nefarious.

I need to look at the press release again. Was it stated that it was running the canned tune that comes in the turn key kit?

I see runs done with both a 2.5" catback and factory exhaust. The catback adds quite a bit of power, which makes the LTH thing pretty curious.

It'll be a while before I drop the cash on a kit so I can see how it plays out a big longer.

With the exception of the carb kit i don't think GTM has just a single tune. They give you a great starting off point, but i have heard several people on here mention that they sent Sam back a couple of data logs and received a tune that is tweaked for their specific car.

as a reminder to everyone..this is a REVIEW thread..please allow those who actually have the kits to comment then direct questions towards them...please try to refrain from bashing or throwing out speculative comments..go to the Stillen thread for that..lol..

^ lol so true.

^^^^ interesting.

Yeah, I'm pretty much in the same boat as Danny.

any new GTM SC installs yet?

[QUOTE=shumby;733196]Also looking at the VQ38 manifold getting on there. QUOTE]

I think you mean VR38.

subed

Interesting thread....subbing


The 370 is entering it's 3rd year. Hopefully the SC for It gets finalized before the 4th year. Don't we get the 380Z by end of 4th yr? :)

Its 4.30AM...I'm about to start her up.

:happydance:

Can you or any of the SC owners possibly post some youtube vids of what this thing sounds like? All the vids I've listened to sound as if there is no supercharge whine present

From the GTM video, the SC can be heard. Unfortunately it is nothing like the Eaton roots type units on previous Z SC kits out there. I kinda like the fact that it is more quiet to prevent some unwanted attention by those folks that are looking to mess with us (both ricers and police).

Are there any Stage 2 kits out there installed? That is the one that I am really looking forward to seeing/purchasing. I would also like to hear some info on the LTH compatibility "issue", as I will be obtaining my headers in the very near future and want to know what my timeline/budget will entail..............
