:iagree:

Take it to a track? We are going to race at 2 different tracks 3000 miles away and compare the times somehow?

I'm not a shop owner or in the automotive industry in any way. Nice try.

oh oh I almost forgot,

IBTL!

Now just to be sporting here is my question about the MAF placement between the kits, How come no one is setting the MAF sensors in a draw through setup so they can actually measure the volume of air entering the engine before it is compressed, and splicing the IAT wiring off to a manifold sensor to accurately measure the incoming air temperature? I restate my question of whether or not you were able to upgrade the MAP sensor to gauge the amount of pressure in the manifold, or by retaining a mostly stock setup do you plan to simply adjust the fuel tables and VE to go around the problem.

Ok now sam answer my tech question

(oh and it's been almost three weeks now are my test-pipes still on back-order)

MMC Racing....Sounds like a shady and fake sponsor name. Do you have hidden business going in via PM? Dont like the accusations for no reason do ya?

Its ok though. Dont come out here. I know I would hand your *** to you anyways. :tup:

Ok i have had my wars with MMC before and i share your anger but lets just chill. (and if you have an LP640 you'd fookin waste him, and if i'm ever out by you can we cruise sometime?)

Oh and this is the GTM supercharger thread someone could get murdered in here and it wouldn't get locked unless they wanted it to

These are legit questions that potential customers/early adopters should know about. Asking these questions is a lot different than just mindless bashing. Nothing wrong with getting as much info as possible before spending a pretty large amount of money, right?

However, to make sure things don't continue to spiral off the original topic, I do think that questions about the Stillen kit should be asked on their thread and that questions about GTM's kits should be on this thread.

Let start with map sensor, the map sensor that you're seeing is a very low range map sensor or in a better way to describe, it is a barometric press sensor, It is mainly there for altitude compensation.

The key of placing the intake temp sensors as a blow through is to give the ecu the most accurate info possible so the intake temp compensation can be effective .

If you place the sensor in draw through setup, compensation for heat soak condition(for example) will be impossible and if you put it in the charge pipe (the stillen kit) then you are always reading the hot air out the blower .

Therefor placing the maf sensor in a blow through will gave us the most accurate reading of air temp before entering the engine.

Sam

I know it's a 1bar map thats why i asked if you upgraded it to like a 2bar, but i don't know if uprev supports the map scaling to do this.

What i ment is why not add 2 IAT sensors and splice the wiring from the combined charge sensors nissan gives you to them so that you could have a more accurate draw through MAF as well as charge temp compensation from the IAT's

Edit: I'm fairly competent with EFI and F/I as i've done NA conversions before so i know what the sensors do

Edit2: I'm wondering how you accounted for the increased density since a blow through MAF cannot pick up pressure and the factory sensor can't either

GTM, any indication of what HP rating the intercooler is good to?

And why would want to tune via Map and not Maf, This is like going backward

Sam

Sam,

Please keep your comments in regards to our supercharger kit to the facts...Your information about our kit is inaccurate.

Best of luck!

700HP

Sam

And because of some members....drama has now come to this thread. Thread locked.

Thanks.

I'm sorry i was under the impression that the car uses both sensors for fuel, timing, and load calculations, I'm sure you will make it work as i have confidence in your shop i was just curious.

Sam,
What are your thoughts on the "equal pressurization" and "equal air distribution" issues that are supposed to arise if the stock intake manifold is used in an SC kit?

personally i don't even understand that as the stock plenum is mostly open on the inside with the runners crossing each other like if you put your hands together and intertwine your fingers.

Thank you for your support Kyle, and the best of luck to you too

Sam

Oh buddy you had to take it to next level :D

Sam

Haha, I swear I'm not trying to be a trouble-maker, but I really do want to know if that's a legitimate issue or not. And I'm trying to keep my questions about each kit in their own discusssion threads.

Can i mention the S word :D

Sam

So you're saying that the air pressure/distribution would pretty much get evened out once it enters the stock manifold?

Haha, I guess you can mention "other intake manifold designs" vs. the stock one, right?

pretty much for the pressure. I could see it affecting an NA application if the tubes were off by a lot as the air would have to flow across from the other throttlebody but for F/I the air tank would be pressurized anyway. So long as there wasn't a huge difference between the tubes it should work itself out so the GTM kit is most likely in the clear

By just looking at a dyno graph for a stock engine and how flat the curve looks gives us a good idea of how good the stock manifold is.

Intake manafold tuning is lot more critical in n/a tuning not in forced induction applications.It is the total opposite because you have to relay on the manifold design. So by adding boost to the engine all the air gets evened out in the stock manifold, not to mention the VVEL that makes things even better.

One more thing, if we were trying to make a 1000WHP @40 psi then I would say then yes redesigning the manifold is a must but for what any company with a supercharger kit is trying to accomplish the stock manifold is more then fine .

Just go to our web site http://www.gtmotorsports.com/customer_vehicles.php and you will see a lot of VQ37VHR engine running boost with the stock manifold .

Sam

I have been looking into GTM products with great admiration over the past few months, with them being on the top of my list for future FI for my 370z.

After coming on this thread tonight and witnessing the past few pages of this thread, all I can say is that GTM has been moved to the bottom of my list.

I expect a much higher maturity level coming from a vendor here. Vendors are here to put out their products for us to buy, the general public is here to make assumptions, flame, put down other products, praise, review, etc.

Stillen, whether your s/c turns out to be crap, or a good unit, I thank you and respect you for keeping yourself composed and professional while all this flame posting has been going on. GTM....you have a lot to make up for and your s/c kit better be a gift from god of the FI market.

STILLEN: 0
GTM: -1


P.S. Sam I believe you need to talk to Tony over at F.I. to give you some PR tips

^^Whatever...When did we all start thinking that commenting on the competition is a bad thing? Thus far all of us have made many speculative comments based on pictures and that's exactly what the spy shots were released for. Even AAM got an early post on this implying it's better to go with a TT setup. A little banter between GTM and Stillen does nothing but give us an experts take on their competition as well as incentives to come out with a very high quality product at a reasonable market rate. I doubt anyone in the SC market is going to think twice if GTM puts out a great product because of Sam's actions. Stillen and GTM are in the market to make $, I'm happy to see that they also don't mind debating and discussing issues like every other member on this board so don't be so damn sensitive!

Let's try to keep this to a technical discussion concerning GTM's SC. We shouldn't have to wade through pages of off topic posts to find info about the kit. Can a mod clean this thread up and delete all the pointless posts (including mine)?

Thanks.

You miss the point as do many others. All I want to see is technical debating based on facts and hands on experience, not opinions from looking at a few pictures.. THAT is what brings value to the community. Debating what is vaporware at this point in time only stirs the pot and is pure posturing. Never forget what the all mighty profit motive does to impartiality.

It is slightly ironic that members will be called out all the time for making comments with 0 hands on experience, but Sam can't be challenged for the same thing.

His comment seems pretty accurate to me. I like both systems but there are things in both systems that I do not like.... I will not pass judgement until I see dyno results on both systems. Sam's statement is correct according to a Nissan master tech that lives next door to me, that is also heavy into modding the Z platform since the Z32.....

:iagree:

SAM WHERE IS THAT PRESS RELEASE! :confused:

lol I think it is still like 6am in Cali....

God help the moderator who will clean up this thread

I think we need to give GTM a break they are working there @$$ off to release this kit. They run into a problem, very understandable.
-Thanks GTM for all the hard work im sure it will pay off when the smoke clears!

You guys are on! I would gladly accept the help and company on this project. I got the tools and the garage and a liquor store less than a mile away.

Thanks for the explanation, guys. Looking forward to more info soon.

you check out the intake manifold thread? it's down in regular engine and drivetrain

GTM, only a few more hours until I go to bed. The clock is ticking.

I can stay up a little later, plus 3 hour time diff :tup:
