The pulley that made 8 psi on the VHR is making 11 psi on the HR engine. Point is that what you see here is just a quick exercise to make sure every thing is working and falling in place. It really took about an hour of actual tuning time to get this results so far. Will need to spend some more time with car to see what will be the final psi that we need to run to get the 500 HP Goal we are after. But so far so good we are already there on stock exhaust and cats .

Very Nice! This is obviously the Stage 1 kit running on how much Boost?!
Any chance we can get a Vid clip without the Dyno noise
Do a a drive by.
I am interested in seeing the Stage 2 kit results. Also what Boost will it will be using.?
What will it take to hit the 500 RWHP mark?! Thats what I want to know. I want to be in the 450-525 RWHP range with HKS Hi-power true dual exhaust, Crawford HFC's and Stillen headers...
Whats it going to take?

As for the stage 2 kit no time frame is set right now so it will be a little while before that become available.

I have some Fuel management questions.
I already have UpRev. Would I have to ship GTM my ECU for the turn key version? I would like to have my car custom Dyno tuned for my Mods! The closest shop is 4 hrs away. I could trailer the car but would prefer not to. I would be taking it there anyways to have an aftermarket clutch installed. These are all things I need to hash out over the phone.
Post up a Vid with the car not on the dyno so we can hear the engine without the dyno rollers. Also will you be putting up a graph of the Boost/HP/TQ curve? Curious to see the complete powerband.

We have done it this way for the last two yeas with all our turbo kits that have been sold world wide with excellent results .
Here is the a little more details about the process

What do you think the install will be like? I know it's technically a 'bolt-on' but what are we looking at here? Engine pull or can it all be done from in the engine bay? Is this something that would come with install instructions? I am curious how DIY-friendly a project like this would be. Definitely do a writeup if you go through with this!

Finally!!! I have been waiting so long for this. Here are a few of my questions I have off hand:
-Can stg1 run up to 10psi? Do you offer a pulley for that or must you upgrade to stg2 to run above 8psi?
-Why does the 350HR only have 1 air filter compared to 2 on the 370 kit?
-Do you think with appropriate HFC's and a good dual 2.5in exhaust you would see 450whp+ with the stg1?
-Like asked earlier why does the Bosch DV flutter so much in the video...that isn't correct. Is it the V710 version of the Bosch valve?
-Will a competition oil cooler fit with this kit? I assume so but just want to be certain.
Very interested in one of these kits if I can get more info on it.

-The 350ZHr chassis has more room so we were able to run a larger single inlet pipe with a bigger filter vs the 370Z.
-Superchargers require back pressure. usually HFC and headers are not a good choice with a supercharger system, they can cause a drop of boost. The stage one kit is designed to accomplish 500 BHP which equal 410 WHP, So far we have made close to those numbers with all factory exhaust and cats components, We are going to be testing with a better exhaust so expect the numbers to be higher .
-A little flutter is normal to a certain degree, we will be trying different bypass valve to see if we can make it better .
-Fitting an oil cooler is possible, we may have to play with dimensions of the cooler to accommodate the supercharger kit .

So this is what I am thinking:
GTM Stage 1 TT turn key kit
GTM oil cooler kit
HKS Turbo timer Type-1
HKS EVC boost controller
SZ High 5 clutch
water temp gauge
HKS AFK controller would be sweet but to much $$$ I also don't have extra bung in Crawford HFC's & I don't want to run anything else. Would have to weld one in
Run on 93 oct with 9-10 psi boost should be right where I wanna be
Any discount for ordering all at once? lol Or I'll just buy the extra's first. Pickup the kit last.

Is the compressor that much smaller that you have to run 11 PSI in order to make 400WHP? How big of a drop in CFM from the VHR kit is it to the HR kit? No big deal just curious. The kit looks awesome so far, how long until we see some dyno numbers for the 08 G35S 5AT you have a kit installed on? Thanks Sam.
We will be on the dyno with the G35 HR this afternoon .

I am starting to releaze this! Sure I could do the Stage II SC kit but the boost levels would be well above what I want to run to achieve the HP I am looking for. I would settle for 475-485 whp with an SC but if I go TT I want 500-520 whp. I want to be in the 500 WHP club! lol

Sam, add some photos of the front with the fascia put back on! Also, as others have said, videos with the car in motion, acceleration, etc would be greatly appreciated. Finally, does anything need to be significantly fabricated/modified for the kit to fit, or is it simple relocation here and there and maybe a few holes drilled?
