/sigh here we go again

If GTM made 460 rwhp then just think what my stage 2 will make.
I will be happy if it makes 450 rwhp. (if it ever gets to me ).
It looks like the average GTM makes around 400 rwhp and that not SAE measured.
The real # would be around 388 to 390 SAE.

I'm not sure why you keep saying we advertise our kit as 460whp. We have said this time and again, not to mention it is on our website, that our Stage 1 Supercharger kit is rated as 500hp. The reason why we rate it in hp, is that there are too many variables involved in wheel horsepower numbers: temperature, elevation, gas quality, dyno type (and dyno setup), and the car itself.

So far, we have many customers that have installed the system and they are on target for the average horsepower we anticipated. At no point did we ever say that our kit is going to make 460whp.

Take the same exact supercharger and install it on an engine that doesn't have crazy overlap (read VQ35HR), and the kit is capable of making 487whp without any special intakes and on stock cats and HKS cat-back exhaust. That's with full control over cam timing (intake and exhaust).

Do you think those power levels will be unlocked on the VQ37 with your VVEL controller?

I think the inability to tune VVEL has always been the limiting factor, once they crack it everyone using F.I. is going to see massive gains.

speaking of headers, i heard a rumor that GOOD headers have equal length runners ... any truth to this?

I did. AND i have stock exhuast on from the convertible which is supposed to be just a little more restrictive. Nothing else done to it. I dont want to get a louder exhaust becuase its already really loud with the top down.
OH i got
430HP/ 340Tq

Pictures of the 430?

Um. Ok?

Really dude... you're getting very, very annoying.

Regardless of the VVEL limitations, it appears the power curve is smooth and comfortable to drive throughout the rev range. There's not much to brag, but as long as it makes the car more fun to drive in any gear who gives a crap other than... where's the vids?

I hope VVEL gets cracked soon.. This is like waiting on an unlock for my iphone 4.. No bueno!

You guys should leave RCZ alone. his stillen works and makes good power.
He has made some good contribtions to the 370 z forums.
Everybody has there opinons. It why we have this forum.
If Shumby and RCZ have different veiws good for both of them.
Im still waiting for my stage 2 GTM ( since Feb 2010) at least he has a SC car to drive and according to Jnaut. it runs very well.
Everybodys RWHP #'s are slightly inflated on there products
I persoanlly went with the GTM . If i do not have the stage 2, traction control and Up rev by April 2nd and miss the opening drag racing day up here i will have lots to talk about
I will be looking for a big refund check from GTM.
In fairness he did offer a stage one and a slight used stillen kit.

Just like Drag Radials will cost you E.T's at the track :ugh2:

Clearly the GTM stage 1 kit does not flow enough air plain and simple look at the graphs his numbers start to die off after he hits 8psi.

Secondly dont hold your breath for the stage 2 kit...

It should be noted that Shumbys car is a 7 AT. The car that GTM used was a 6 MT. There will be a few extra rwhp as the difference of loss in the transmisions.
I would expect his car to make 416.76 rwhp @ 8 lbs.

Relax im not picking on RCZ. Both stillen and GTM are good companies and both have their pros and cons. Everyone has different car setups so there bound to produce different numbers. I just find it interesting that we see more GTM superchargers then stillen superchargers. Numbers speak for itself. As long as there happy with it, that’s all that matters. Its good having people like theDreamer explaining the process of how he got those numbers with his LTH and supercharger. That setup his has is something that the community has been waiting to hear. I am glad he did it.
Sam at GTM, I stopped by his shop a few times, I can see why he is busy as he is. Good things happen to those who are patience. Sam is a very knowledgeable when it comes for imports and z's.

solid numbers..glad to see it worked out for you.

I am happy to see the results, Great numbers.....


I plan on a Similar set up....



DAN

:drama: It is good to see these companies chime in and back up their products. I just purchased Tony's Coated LTH cus I plan on going with the GTM stg. 2 kit.

^^^^You and I are way to similar :)


09 White 370Z with LTH and GTM SC Kit LOL



DAN

That's pro, we have good taste ;)

Looks Great. Nice numbers!

Nice numbers dreamer glad you like it =)

400 rwhp!! nice. very nice

That what matter the most Matt :tup:, Thanks for sharing .

Sam

Depending on which compressor gtm using with the stage 1 kit.

According to the mfg spec of each compressor:
C38-61 - 300-550hp .50kg/s converted to 66lbs/min
C38-71 - 350-590hp .52kg/s converted to 68lbs/min
C38-81 - 400-630hp .55kg/s converted to 72lbs/min

and the C38-91 is 11 percent more then C38-91.

Converting the flow rates .63 kg/s to lbs/min (like most turbo guys refer to), the c38-91 can support 83lbs/min! 800hp!!

Did a few things to make it fly right..
 

I Had to fix a-lot of things that were bought installed and promised from gtm. It took Mr. Church, Mr. Tony of FI, plus a few friends with good wizards "to make my ride right after the "gtm upgrade". Keep shopping all, there are lots-o-stuff for your fun out there now days, for alternative upgrades that work without intervention on the post build reaching into the $$$$$.

Take care all.

WTF did u just say?

Read it again.

maybe he cant read.

Like I'm going to believe someone with 20 posts saying that an unnamed gtm kit is garbage, come on rly. And jamaica if your just going to post negative things you could :gtfo2:

Brrrrrrrrr - hold your horses, everyone :hello:

There goes that free speech thing again right out the window, what were those 1776 guys thinking anyway.

Dude, no one said you can't have free speech. However, even free speech is limited by defamation. Yes, a lot of us on here are GTM fanboys, they have done a lot and continue to do a lot for the Z community. However, if you have a story, spill, don't just allude to it.

Hello all; new to the Z world...

Just purchased 2011 370 two weeks ago, but have not made an introduction post because my baby has been at the dealership since I bought it (new transmission and getting some scratches fixed).

Anyway, coming from the Mustang world, the 370's are new to me. I was looking at the dyno posted and have a question.. Is the A/F safe running that lean with 8lbs of boost? I have always had my boosted stangs tuned to 10-11, but never anything above 11.

Just curious...

Jeremie

I think he's geting it from the first SC anouncment page:

http://www.the370z.com/forced-induct...s-release.html

toward the bottom of the page.
The mistake he made is that you do claim 468 BHP, not whp. To be fair to him, you do show 452 hp on a stg1 graph @ 8 lbs that seems to indicate whp (never seen BHP displayed on an actual dynograph before). Mostly, just a misunderstanding.

What exactly did you have to 'fix,' you came in this thread posting a bunch of stuff was not working which was promised and it took others to fix it. Are you running a GTM Stage 1 SC with LTH or just randomly trying to start a flame war?

Yes it is safe.

2011 Z scratched and with bad tranny? What happened?

Lol y u mad?

Start a flame war? Nice, just giving my witness, and based on the bashing given out for not drinking the Koolaid, what would be the attraction to say anymore, carry on and best of luck to you.
