Yes but now it will need to be re-tuned for the other pulley if he ever gets it from gtm. You know vsr makes an awesome single turbo kit from what I hear and at only 10psi makes just over 500whp on a stock exhaust.. Even with that other pulley your only looking at another 40-50whp and 40-50tq...

Trust me, I know the pain... I am having to buy a whole bunch of parts (e.g. O2 sensors) that GTM did not return to me when I liberated my car to get the car back running. Not pleased.

Looks like sam does it again, another happy customer..

I didn't realize that, can a 1 be upgraded to a 1.5 later then?

Yes. In fact, I think 1.5 really only exists as an upgrade kit. Search for the original thread on it.

It was clearly a trick question, as you would never receive the parts to do the upgrade...

Sam claims that one issue is that the Rotrex SC needs to be broke in with 60 miles before being revved WFO which Bobby says he didn't do. Supposed to gain more boost when broke in.

it is a friction drive so that would make sense. hopefully they don't get damaged if ran to hard prematurely.

So you have the 1.5 then?

Yeah, I've heard the same

And yes, he does

Do you really think breaking in the supercharger is going to yield another 50 or so whp? I'm guessing the only way it would show more whp would be if the temps are cooler if they dyno it in the morning and even that without touching the tune would be very minimal..

There is another issue going on, this kit puts out 485-500 to the wheel with the 88mm pulley all the time.

If I had this kind of money to throw around I would just get a C7 and call it a day. I can imagine the wife's look when I tell her i need a turbo kit on top of the SC. :eek::gtfo2:...and out I would go.

buy a Chevy.. never! Hope it gets worked out! Boost is, great.

I don't car for American vehicles either but the C7 is pure sex. I just want the Z51 package and the magnetic ride control and you'll never hear me b*tch again.

*yeah...right*

Did they smoke test it for boost leaks? is the bov sealing? Is the belt tensioner working properly? also what do you have for headers/exhaust?

On another note if I get a different car after the Z I'd see if i can squeeze into a lotus elise and then supercharger the bejeezus out of it.

Bobby stated it was put together correctly and the BPV and belt were functioning correctly.

In for details tomorrow..

Thread title change to "What has shipped?!?"

Did you figure out whether you actually have the stage 1.5?

if your car has the big intake pipe to the right of the charger in this photo it has to be a stage 1.5

Edit: looking at the photos it looks like the differences are in the housing/intake/filter, charge pipes look bigger, and motor mount.

Edit2:aparently that pic is of a 350hr kit damn google. if anybody has a pic of the vhr kit use that to compare, no wonder the pipes look different :facepalm:

Yes stage 1.5 uses the stage 2 Intake piping and motor mounts. The air filter on stage 1.5/2 faces back towards transmission
The manual for 1.5 is the same as stage 2.

Me too. Woke up this morning depressed by the whole thing and don't have a good feeling about it at all.

Keep your head up bro! Bobby will help you anyway he can.

Put the car in the air and post a picture of the SC.
That will show us what you have for a an SC

Z

I'm in Orlando, VSR is in Tampa. I think it's the 1.5 looking at the filter system. GTM sent only one filter, the stage 1 has two filters. There's gotta be another issue.

compression test?

Edit: that would explain low power but not low boost pressure, hmm...

Car has less than 14K miles...compression better be spot on.

How many miles have you driven the car with the SC on it ?

LOLOLOL............................none:shakes head:

Haven't even gotten it back yet and no idea when I'll get it.

not to be a ****, but, I have read nothing but terrible things about GTM here for the last year. I would highly recommend selling your Z and going with a C7, YOU WONT REGRET IT.

Plus, on this big old V8, you look at it wrong and it makes 500wheel.

Listen man I dont know what exactly you were expecting as far as final numbers but for the money you spent I would have gone with a good turbo kit.. There are plenty of threads out there now that have alot to say about gtm so its not like you didnt know...

Unless I missed it your sure its the right pulley or we know it is not? The numbers are right in line with that boost pressure on the FI finished build thread, if everything else is correct another 2 psi would get you to where it needs,to be.

It wouldn't be unthinkable that they included the wrong pulley.

I heard from bobby that they re-dynod it and it made the same power. At this point I would enjoy your boosted z and hope and prey you will not need anything from gtm later..

If it's the wrong pulley I'd assume you could get it from the manufacturer. Is it a Vortech or Rotrex?

Ya skip the GTM fiasco, go to the souce, good call chuck.

I've gone through this several times in multiple threads already but I'll do it one more time to get you up to date. I came on the 370Z scene a little over 13 months ago. Read plenty of thread/reviews and did some test drives of various vehicles and decided on the Z. I liked everything about the car except the power but thought I could deal with it, a short time later I figured out I couldn't. At that time I decided to go SC and there were only two choices. I read some threads and quickly realized Stillen was OUT, that left only GTM. Another member on this forum pointed me towards the MHI kit that GTM was getting ready to introduce. I thought WOW...$6K shipped, that's great. Everybody was talking positive about it and a lot of people were signed up, so much so I was #80. I believe at that time even YOU were talking positive about GTM.

There's not one manufacturer or shop that doesn't have negative feedback in their history and I should have done a better job of resarching GTM's history but forum heavyweight's like SPOHN had signed up for the MHI and talking very positive about it so no red flags were hitting me over the head. The only other TT options I had were GTM, Greddy and FI which were both more expensive and/or not out yet or not on the shelf and had to be produced. The singe turbo option were BP and VSR but at that time EVERYONE was jacking GTM and their unborn MHI kit so that's where my focus was. With my limited budget I made my choice and went with the MHI.

Last December I got tired of waiting and changed my order to a 1.5 SC since Sam already had $6k of my money it was a quick decision to go with a product that has already been produced. As far as numbers go I don't know what you've been telling Bobby but you have not done any research as to the HP capabilities of this kit. This kit with the 88mm pulley gets 500 on a regular basis, only one of the three finished builds on this site was in the 480's and that was due to a fuel problem. Jon at Z1 has done multiple builds that have gone past the 500 mark, even Baer got like 513 with completely stock exhaust. Stage 1 kits get close to 450. My expectations are nothing more than what most people have gotten, I've paid full price for the kit and am paying full price for the install I expect nothing less in return.

Understood man and I am on your side here but I wouldn't blame bobby for your loss of questionable hp. Different cars, dyno's, etc. I hope you get it worked out..
Just curious but is the break-in period in the gtm instructions for the compressor??

From what I understand they are but as Bobby states they should be in the first few pages.

Yes, as per GTM instructions it says "A break-in period of 65 miles is highly recommended. During the break-in period, stay out of boost(boost gauge highly recommended) and do not rev the engine over 3500rpms."

As for boost levels, 9-10lbs is what you should be getting. I have the same kit with 88mm pulley putting down 513whp and never seen more than 10lbs even during the dyno tuning. If anything, you may have a slight leak somewhere but still with that much boost you should be much closer to 500whp. There must be some other issue going on. Hope you can find it ASAP. Good luck

It still kills me to see GTM doing so poorly lately. I must be one of the few last ones to get lucky because they really took good care of me. Even had one very important part that was wrong during the install but it was shipped overnight without any hustle. My complete kit itself arrived at my door step in east coast 5 weeks after I sent my payment.

I still hope they turn it around because they really do make a great product.
