GT Motorsports: 370Z Supercharger system development

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?

1slow370

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.

SAM@GTM

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

Sam

SAM@GTM

Oh buddy you had to take it to next level

Sam

Buddy Revell

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.

SAM@GTM

Can i mention the S word

Sam

Buddy Revell

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

Buddy Revell

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

1slow370

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

SAM@GTM

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 .

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.
