GTM Supercharger Stage 1 w/ F.I. LTH

Mike@GTM

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.

Mike@GTM

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.

SAM@GTM

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

SAM@GTM

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.

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

XwChriswX

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

Mr.Squeeze

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 GTM Performance Engineering 370Z SUPERCHARGER KIT PRESS RELEASE. 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 GTM Performance Engineering: Stage 1 Supercharger Upgrade Kit 500whp capable .

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,

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
