GTM Performance Engineering 370Z SUPERCHARGER KIT PRESS RELEASE
 

We are please to announce the GTM supercharger system for the 370Z. Our GTM supercharger system will be utilizing the Rotrex C38 supercharger, The Key to the Rotrex supercharger is unique compactness, efficiency, low noise and reliability and its state of the art traction drive technology.

Great speeds and low noise are just some of the advantages of traction drives over traditional gear transmissions. Traction drives transmit power through friction forces between its rolling elements.

The Rotrex traction drive uses an elastic annulus with a small pre-span to secure contact between the roller planets and the sun shaft with a reasonable force. The patented "ramp effect" increases efficiency and reliability in the transmission by regulating the torque transfer capability on demand through self-adjusting planet geometry.

To enhance performance, the Rotrex traction drive uses a special traction fluid. These fluids are a new family of synthetic hydrocarbon oils and greases offering a series of unique performance advantages. Developed specially for its use in Rotrex superchargers, the SX100 momentarily increases viscosity under high surface pressure, enhancing the traction drive performance by securing the optimum friction between rolling elements while cooling and protecting the system.

This traction drive combined with the latest technology in centrifugal compression, characterized by high adiabatic efficiency and low noise, gives Rotrex superchargers an exceptional competitive edge over any other forced induction solution.

The GTM Supercharger kit will Have four different Rotrex compressors to chose from: C38-61 Trim,C38-71 trim, C38-81 trim,C38-91. Combined with our custom compressor housing we will offer three different stages .

Stage zero up to 450 HP (carb approval pending)
Stage one up to 500 HP
Stage two up to 525 HP
Stage three up to 550 HP

All of our Supercharger kits are available in two forms. The tuner kit form, so the professional and the end user have the flexibility of choosing what ever fuel and engine management they may desire and feel comfortable using. The second option being a complete kit including fuel and engine management solutions. With that being said, GTM will also offer an extensive range of fuel system and engine management modules to go with our Supercharger kits.

Some Key points about the GTM supercharger kit

After literally installing and tuning every supercharger kit available for the VQ platform and seeing their short comings, we got the inspiration to develop a kit superior to all others. Problems with the other kits that we wanted to address with our own include: not supplying a descent amount of power, belt breakage and slippage, obnoxious gear lash noises, limited power expansion and lack of the OEM look. Some of the key things we did to achieve our goal are:

SUPERCHARGER NOISE : We chose the Rotrex unit, a very QUIET supercharger compared to anything else on the market .

SUPERCHARGER BRACKETS : Our supercharger bracket is 3 dimensional made out of of thick billet aluminum to prevent any flexing, we also mounted the supercharger unit as close as possible to the engine to limit the amount of flex possible, as well as keep the belt length down between pulleys.

BELT AND TENSIONER DESIGN : We have over 80% belt wrap on our supercharger's pulley and with utilizing the factory automatic belt tensioner over or under tightening is simply not possible.

POWER EXPANSION : Changing the pulley on the super charger is less then 20 mints job

AESTHETICS : The GTM Supercharger kit maintain the clean oem look

ENGINE MANAGEMENT: With using the GTM flash we are to able to maintain the OEM drive ability so the car will run like stock, only with a lot more power .

POWER DELIVERY : The GTM supercharger is best bang for the Buck out of the box

***Update 1/4/12***

We have the CARB Test Letter in hand! This means that CARB has approved the components in the kit and they have everything they need with the exception of final emissions testing. We are *this* close to getting approval.

Sam

Simply awesome, Sam! Incredible job!:tup:

so ******* tired, i'm glad it is done .

Sam

PM sent.

ok now I really want that proposal from you

Incredible piece of work! That's just a work of art. Sam, what will the price difference be between the Stage 1, 2, and 3? I'm interested in the Stage 3 system, including full exhaust. Do you recommend your 2.5" or 3" exhaust? Will this setup work with long tube headers? Yes, lots of questions.

So I am in at the pre order price right? Even thought i will ont be getting ti installed by you until may/june? Do you need a deposit?

plus one on the LTH as I have them ordered.

hmm, I must have missed when Stage 3 turned from the 81 trim to the 91 trim.

Sam, take a nap :tup:

So does the intro pricing apply to all trims?

Good question.

Also, I noticed that the C38-91 won't be out until late spring/early summer of 2010. Any comment?

From Rotrex A/S

FWIW, I'm interested in the Stage Zero turn-key kit. $4995 for ~420whp is a great deal, IMO. Interested on when the kit would actually be available and what kind of pricing I'd expect if I ordered after the introductory offer period.

... another good question. I won't be ready to go FI for some time.

That is a fantastic deal. I gotta talk to the wife.

Sam! you guys just knocked this one out of the park!!! with that price point you should sell ALOT of kits quick!!!

I was shocked at the pricing, PLEASANTLY shocked, i was expecting somewhere around 7k, bravo GTM, BRAVO.

WOW Thanks for the info!! That is an amazing price!

I will post this on ChicagoZ to make sure everyone knows :)


DAN

Wow this is exactly what I was hoping for! Wonder how long the intro pricing will last. I'm still a little ways off from having enough cash.

Barvo GTM, barvo :)

Nice work guys
Any ideas on install price (drive off) ? with the fair deal here, install costs are more reachable ;-)

Fuel upgrade costing, I assume , single pump , 600cc DW injectors etc.
Will you have relevant starter maps for the popular tuning platforms?
PM if you want.
Cheers

I think you'll still end up around $7k if you try to "do it right" as it were. Think clutch/flywheel, gauge setup, and perhaps some installation cost.

Still, $5k for a turn-key kit that puts out 420whp is very sweet. I was, like you, expecting to see something in the $7k range.

I like what you did with the recirc, clever placement!

Got any pictures with the bumper on??

Good pricing too, its exactly what I expected.


Few quick questions...

1) Which trim is that in the picture? Looks like a tight squeeze already, wondering how the bigger ones will fit?

2) 90* elbow after a flattened intake tube and two 90* elbows on the way to the intercooler?

3) Hydrolocking concerns with the filters at the lowest point on the car?

4) Does that oil cooler sit behind the stock bumper?

5) What kind of dyno? What did the stock 370z put down on it?

6) Spellcheck

Sam you are going to sell tons of kits!!! Well done. As far as the Nissan aftermarket goes, I think I would take you guys for parts over stillen any day of the week. Masterminds in the Nissan/infiniti market, pure genius, congrats!

Raul,

My guess is going to be that hydrolock isn't much of a concern. Even with the "bulkheads" removed I don't think spray is going to be a big problem (the filters are far enough off into the corner of the bumper area that it's going to be tough for a significant amount of spray to make it's way over there.

I'm sure it will be fine unless you drive through deep water.

As for 2... I think you're right. Probably not ideal but my guess is it's the best solution possible given the space available.

well done :tup:

Z eliminator

Nice, I'm in!

WOW! :tiphat: Good work Sam

I am actually very happy to eat my words from my previous predictions. I did not expect this kit to come in at 5K but I am very happy that it did. Damn it Sam, Now I am going to have to re-think the whole SC vs TT setup again after I thought I had my mind made up. I love how clean it looks under the hood and it sounds really sweet! Either way I go, without question GTM is getting my money!

I am very impressed with the results at stage1 on stock exhaust.

:excited::excited::excited:

Let me add, NICE machine work! I am very impressed!

hey Z if you are talking to Sam again get him to get me an e-mail he has my address. I cannot call him as I am in russia. I want the preposal he promised me. Really excited now

Yeah man, my bumper is less than 4 fingers off the ground... 6" of water and that lower intake is submerged. I have seen waaaay deeper puddles around here. I'm just thinking what would happen if I had no choice but to go through something deep?

And yes, it was the best solution...if you put the sc there.

Steve, looks like you're gonna be making quite a nice amount of power! Congrats and you must post pics and review when you get it!

This is awesome

I wonder why the pics are not loading. If I quote sam and copy and paste the actually links into another window they load fine....


I have one question though with the oil relocation kit. It looks like the oil filter would be right against the bottom engine cover. What happens when someone uses a sandwich plate for the oil an oil cooler, which is pretty much a guaranteed item?

Suddenly I am interested.

edit: My only real worry would be an installer on the east coast that is close.

To Shumby

I spoke to Sam last night for 45 min at 11.00pm. I reminded him that you sent him a "PM".
He recevied it but has been too busy to get back to you. He has been up to many late nights working on the SC. He told me that he will get back to you ASAP.
I did not forget you, "my fellow Canadian "
Did you see the Hockey Game.
Canada 3 USA 2
2010 Olympic gold metal Champions.
It was madness here in Toronto last night.

Thanks for looking out for me. lol



Ya the game was stressfull. I got to see it but all in russian. lol Made $50 off of it too so it was all good.

Sam, congrats. I think you're doing the community a service with this pricing, so thanks for digging deep and making it affordable...

some more questions:

- I'd really like to see the weight of the components listed out... what is the net weight change for someone pursuing each kit stage? we can do the math ourselves if you give us component weights

- I agree with the comment about the oil filter... that scares me, my car is lowered and I bottom out all the time at the track... with a sandwich plate, this thing is going to strike the filter to ground, which can only be bad... can you redesign that adapter and move it up a little ?

thanks

have some manners :stirthepot:

why are you instigating?

i think we are fully aware of the fact the neither stillen nor GTM would make such a comment on each other...........

what a shame.............just foolish and childish.........

on that note, SAM have you pushed the SC kit to the limit, either track or street?

i figure your team had been too entangled with R&D that you might not have had the chance to test the durability and drivability of the current set-up......

still a long way to go, but just curious.....:bowrofl:

and a pissing match ensues..

http://www.crackunit.com/wp-content/...ll/pissing.jpg

wow. This kit looks amazing and the dyno looks great. I would definitely like to see some performance measures on the road. Also, for us Cali people, having a carb legal kit would be awesome!

Actually, it wasn't, you are really looking for something if thats what you thought. You're the only one thats reading into everything they say. I don't think they want to start drama... if they did they would've said something back when Sam said a few things about their kit that weren't accurate. Give it a break man...both companies are trying to keep it professional.

Just let the manufacturers and, more importantly, their products speak for themselves, bro. No need to instigate.
