Your 'witness' was a blank statement about having to fix something, which many users have just put on their car, tuned and been on their way. When someone comes onto the forum stating they had to call upon many other people to fix something, people would like to know what it is you had to do.
I do not drink the koolaid of anyone, if you spend some time on this forum you might see I have owned almost any product from any compnay. Stillen, GTM, Volk, Takeda, Fast Intentions, Berk, etc. I provide information to help better this community and when someone says what you said, it throws off alarms you are just trolling or starting a flame war.

Please do explain in more detail. I would like to know what problems you had to have all of these people fix.

I agree. It is helpful for the community to know specifics.

Loooong story... Took the car home and found two deep scratches and there was a spot on the roof they touched up with touch up paint. Took it back to have fixed. Picked up the car and come to find out they buffed the entire car and left really bad buffing marks and the trans was no making noises. I think the guy that picked it up to install the leather ragged on it. So now they are replacing the trans and trying to get the swirl marks out. Assuming they didnt burn through the clear, I might be able to pick up tomorrow. If they did jack up the clear, I will be fighting with them to buy back the car and find me another.

So far, my experiance with Dan Davis Nissan has been the worse ever.

Damn, dude, that sucks. Hopefully it is resolved to your liking.

Oh, and from one Mustang guy to another, welcome :tup:

It all depends on the tuner. Some like to add more timing and run richer to make up for the timing. Some like to run mild timing and mild a/f.

I personally like to run mild timing and aim for a/f to be around 11.5-11.8 a/f at full boost.

It all depends on the motor though, some motors like more fuel while others like to be ran leaner.

Who the heck is kingbaby? I help this community plenty, so thanks for the neg rep coward.

My350 troll. Rep added:tup:

Hey troll! Aren't you on vacation? Get off the forums and enjoy it LOL

:icon18::bowrofl:

Ok off to snorkel.

Well someone unnamed neg rep'd me saying I don't help this community. I can call bs on that one as I more then help this community in more ways then one. It's really people like that, that ruin great forums like this one. Let the 350z trolls stay on my350z and continue to ruin their own forum.

+ green pip.

You guys are great lol, I wish I knew who just repped me so I could return the love, no homo

The Dreamer,

What intake piece did you add to help you make that extra power?

No extra piece, all pieces supplied by GTM.

Those are great numbers Dreamer +1 to you, I'm thinking of going this same route with the stillen and the LTHS. Is there anything I need to know before hand or would I be better off with the HFCs?

Interested to see how your number go with the Stillen Kit and LTH's. No one has stepped up to try a stage 2 GTM SC with LTH's and we haven't heard anything on VVEL being cracked anytime soon.

Old thread revival
 

Sorry to be reviving this old thread but I came across is it and I think I am missing something here.

My dilemma is here is why Dreamer is making less power with LTH's. I understand boost = back pressure so freeing up the exhaust (CBE +LTH) will lower the back pressure (and therefore the boost) and make it more efficient, but shouldn't he be making more power @8psi rather than less?

Now is it because the SC is capped @ 8psi that it can't achieve higher numbers or is it some VVEL thing holding it back?

Sorry, not trying to stir the pot just trying to wrap my head around this.

Thanks

The Supercharger Unit itself is not capped at 8psi...our Stage 1.5 Supercharger Kit proves that.

The Stage 1 Supercharger as it was originally designed, needs a little bit of back-pressure from the exhaust to keep the compressor in its efficiency range. Once the exhaust back pressure is reduced too much, the compressor loses efficiency and therefore, makes less power.

If you are looking for more power than the Stage 1, but still want good mid-range torque, then check out the Stage 1.5: http://www.the370z.com/forced-induct...p-capable.html

Ah ok thanks Mike, forgot about the efficiency range. Makes sense now.

Thanks again

Mike@GTM answered this well!

There is nothing wrong with our headers or exhaust. In an N/A application they have big gains across the board...

I do not want to stir the pot as well but the stage I kit is inefficient! I am glad to see GTM finally is making a bigger more efficient kit that can support less back pressure.

I do not think that our headers will fit with the stage 1.5 kit though. I have not seen the kit first hand but I have been told that with the new design, there is no room for our headers!

Thanks, Tony

Mmmm...I wouldn't call the Stage 1 "inefficient". See, there's always a trade off, as you should know. Bigger is not always better.

In fact, there are a lot of subtleties involved with designing a forced induction system. It's not as simple as just tossing a turbo or supercharger on a motor and getting good results. There is an thread on here that exemplifies what can happen with that mentality.

The Stage 1 kit (much like a small turbo), has superb mid-range torque for a centrifugal supercharger. The Stage 1.5 (like a mid sized turbo), gets to full song a little later than the Stage 1, but still quicker than Stage 2 (like a large turbo).

Each one of our stages has its place depending on what the end user is doing with their car. No one stage is going to be the best for every circumstance. Flatly calling our Stage 1 inefficient just illustrates that not everyone fully understands how forced induction really works.

But the question still remains with the stage 1.5 or 2 work with the LTH's?!?!?!?

DAN

If it's the same compressor wheel with a different, more efficient, housing on the stage 1.5, why is it taking longer to come online?

I don't know, I can only speculate. Someone is just going to have to give it a shot and report back with the results. That is the only way we are going to settle it once and for all.

It's a combination of pressure ratios and pulley size. Keep in mind that it is the same supercharger...all we're doing is shifting the pressure ratios.

No it wont. And even if it does, Why would you do that, We are making Over 500 RWHP on stock exhausts and Stock cats.

Don't worry i get it Dan;)

Sam

Tony, you don't need a twin turbo to make 450+ RWHP. What is really bogus and unprofessional is for you to keep taking shots at us at all the time. It is true when they say you can't teach an old dog new tricks.

FYI we Made 459 to the wheel 2 years ago. Here is the dyno graph.




Stop the ********

Sam

DAN

cwis...i told you!

Told me what? :ugh2:

well i seem to have really brought this thread back to life. But I am glad good information is being passed around.

If this were true. Sadly, it's not any 'new' information.

Hey Sam I have a couple of questions is this a stage 1 dyno chart correct?

If So what's the difference between this car ,and most of the Stage 1 dyno charts that customers have on the forum's. Most of them seem to fall between 400-420whp.

The reason I ask this is because I have seen some dyno charts of Stage 1 and 2 Stock cats/no cats and exhaust.The Whp in them seem to vary,this is something I have always wondered

Thanks in advance for your response.

Yes, this is a stage one dyno graph from our first R&D car Posted in our press release two years ago. Here is the link http://www.the370z.com/forced-induct...s-release.html. In this dyno graph the car was tuned aggressively and the supercharger had a wide open intake, As we have stated before. The sole purpose if going through this exercises is to really see what the charger C38-81 can do and that is why we always knew that the stage 1 blower had a lot more in it left performance wise .

Sense day one our goal was to offer a system that works around the car and have as little impact on the car as possible. The stage one kit does exactly that and that is why you see the consistency in the results in relation to our advertise horse power levels.

Once we start focusing on the performance goals over little impact on the car as possible, by changing motor mounts,bigger intake and such, we were able to maximize the same charger C38-81 potential and get better results .

Now we know that the C38-81 will max out at a little over 500 RWHP as demonstrated in this thread http://www.the370z.com/forced-induct...p-capable.html .

As for the variation that you might be referring to, it's mostly when we are in research and development phase, but ones the product is released i think you will see a great consistency in all our product.

I hope i have answered all you questions.


Sam

Sam,

Running stock cats on a force inducted car for a long period of time is a bad idea unless the car came like that OEM. Do not get me wrong, I am not condoning taking smog devices off of cars specifically in California. Hats off to you guys for trying to make smog compliant kit! That will be huge so best of luck getting that.

Boost is back pressure as we all know. So in a nutshell you are saying the kit needs the back pressure from stock (restrictive exhaust components specifically stock cats) to keep the head unit in it's efficiency range! That means the kit is inefficient!

Why not make a Supercharger system that is efficient with a free flowing exhaust system and advertise it both ways? Make the most amount of power on the least amount of boost one way and also show what it does with in stock form. In the end, the free flowing exhaust will have much less wear and tear on the drive train and especially the engine!

Less heat, less friction and the parts will all last longer!

Tony

Dan,

Apparently they will not fit from what I have been told. I tried working with GTM in the past to have a good fit for both of us. Sam fought me the entire way and started telling people our headers were making his Stage 1 Supercharger look bad (in so many words)! I told him years ago over the phone that the kit was inefficient! He told me I was stubborn and did not know what I was talking about.

(IMHO) all my headers did was expose a big flaw in the Stage I Supercharger kit. This is why he has come out with stage 1.5+ along with other reasons I am sure!

You know us and the level of integrity that we stand for! You know that you can call me anytime with questions...

Thanks, Tony

Oh wow
