GTM Performance Engineering 370Z SUPERCHARGER KIT PRESS RELEASE

Zsteve · 09-03-2010, 04:33 PM

I just want to see some kits installed already and see how they are performing. Lets get it on!!!!!!!

Does anyone know if you will have enough space to have a engine oil cooler with this supercharger kit? As the intercooler and supercharger oil cooler seem to take up most of the room in front.

that was answered somewhere in the first 10 pages pretty clearly... yes

Sorry I'm late with this...here is a quick preview of the parts laying on my lovely carpet, rofl.

It might take awhile to process it was just uploaded...

My god, I sound retarded...

Sorry, I'm filthy and pulling an all-nighter with a friend of mine trying to get as much done as possible. I just came in shot the video and posted it, no editing, nothing. Anyway - let me know if you want to see anything specific or have any other questions...

GOOD JOB!
You need batteries for your smoke detector.

^ Haha....yeah..

DannyGT · 09-04-2010, 10:55 PM

negative! I was going to do a proper intro but didnt have time. Thats my parrot in the background. He does that when he calls out for someone in the next room to take him out of the cage. He also mimics cats and dogs to an exact science, LOL

Nice video Danny, I don't blame you for sounding giddy because I would be doing the same thing! This is the stage 1 kit correct?

DannyGT · 09-05-2010, 01:40 AM

Stage 1 and the first stage 1 with meth/water injection too. (i think)

We're still up, 2.30am and counting, intake manifold is off and we're 70 out of 128 pages through! woot!

Did the kit come with all the instructions in that 3 ring binder? That is really nice if it did. Are you running an engine oil cooler? If so I would like to see how and where you mount the inline thermostat and how you route the lines please.

So that tells me that you could use a bigger unit that flows more which would make more power. A bigger unit would flow more and start getting choked up by the amount of flow of the actual motor, thats when you would see PSI start to rise.

So no, its not that people are obsessed with psi numbers, its that you could be making more power because the ENGINE is capable of flowing more than the SC does.

I agree with you 100%. I didn't comment directly on that aspect, but it's part of the same issue. So the converse is that with a smaller sc unit, if you increase flow by reducing restriction, the boost number goes down. Additionally, I'm not even saying using the smaller unit is bad. It allows for peak boost to be achieved at lower rpms and makes the powerband more useable.

Or have they just not chosen to put a larger pulley on it and see? Sorry if this question has been answered previously, I don't think I have overlooked it in my reading through.

I would say the answer is yes, based on: http://www.power-enterprise.co.jp/ro...rotrex/C38.pdf

The unit is rated for 865 cfm of flow, compared to 1150 cfm rating for the Vortech unit used in the Stillen kit. That number is relative though, based on the pressure map. The pressure map in the above referenced .pdf file shows the efficiency range as a % efficiency. You can get it to make 11 psi of boost, but not very effieciently and the volume of air flow will be much lower than its max of 865 cfm. Or, you can go to the other end of the extreme and get 865 cfm of flow, but with no boost, which is also inneficient as a compressor. The "sweet spot", or peak effieciency, is where you are getting good boost and good cfm of flow. The rationale for using this smaller compressor is that you can gear it high and spin it very fast, so that it builds boost at a lower engine rpm, but then in the upper rev range, the boost doesn't keep building.... it just kinda plateaus. If you use a big compressor and spin it fast, you get too much boost at high rpm, potentially causing engine failure. If you use a big compressor and spin it slower so boost is ideal at redline, the boost level in the midrange will be much less than ideal and performance will suffer.

Funny.

I'm going to follow your progress. This looks like the best way to go for my needs!!

DannyGT · 09-05-2010, 01:14 PM

cool, I'll probably get a bit more detailed in my reports in my journey thread in members gallery.
