GTM Stage 2 Supercharger Preliminary Testing Results
 

After months and months of tweaking, designing, we are finally able to throw our stage 2 test car on the dyno to get some results. Keep in mind our intention here is to find what the supercharger's capability is. We were very pleased to find that the unit, although larger in size, was able to keep a nice flat torque curve with better top end power.

We feel this result can give us a very accurate indication of how well the head unit is reacting since we are using the same car, same gas, same pulley. We are still not done testing the supercharger and our multiple intake designs that have been on and off many times to optimize the setup.

Here are the changes we made differentiates the two stages:

1) Urethane Engine Mounts to gain room for the bigger compressor housing which vastly improved engine response by getting rid of the mushy stock mounts.
2) New Intake Design
3) New Compressor Housing design
4) New Supercharger Outlet Piping
5) 3" MAF housings


The results you see are fresh off the press this morning's dyno pulls. After the dyno sessions, the vehicle was off the dyno and the supercharger is coming off the car for the 100th damn time.

After literally installing and uninstalling the supercharger about 10 times this week, countless pulley changes with different intake and tunes combination, We are happy to report that the hard work had finally paid off with some extraordinary results.

Here is some New dyno results

Here are some new dyno sheets from a 370Z Stage 2 Supercharger with the following mods: test pipes, cat-back and our 8psi pulley.

As you can see, it's pretty beast!

A little Teaser video

Awesome results Sam, great power at 10psi. Are you planning on selling those stiffer motor mounts separately?

Yes we will, they will make a nice upgrade on their own, of course they are not for everyone.

Sam

Nice! Looks like ill be going stage 2

Very nice in for updates.

Sam, how are you thinking this will work with LTH/CBE?

Possible to tag 500whp?

Not sure about 500 to the wheels, but the car that we are testing with right now has been one of the lowest power cars we've tested. Also, we are planning on testing with cat-back, test pipes, and EQUAL Length headers. ;)

Stay tuned.

I see the Z Eliminator going low 11's in the 1/4 mile.
500 rwhp = 10.9
The long wait was worth it.
Congratulations Sam.
470= 11.29 to 11.38.

Awesome SAM. I am going to touch base with Zerolift again and talk to Mike about going with this instead of the TT. This kit w/ LTHs is what I wanted all along anyway. You are my hero!

Very impressive results are you guys going to use a smaller pulley with this set up?

We are at the maximum pulley size right now and the size bigger then that only made few horses less.

We don't need smaller pulley, We need less overlap .

Sam

Just wait till i give it some good Canadian cold fresh air and some good Canadian 94 octane gas.
Now we add your new intake manifold and we could see some major RWHP
add the VVEL control
and you will the GTM trackion control
Yes my friends the Z's 370 z is going to be a screamer.

Understood cant wait to see this when you work out all the kinks.

VVEL control

That would be the icing on the cake. Sounds delicious............

Sounds tasty can't wait to hear how it works with LTH

@_@!!!!!!

very cool so far

I will be purchasing this in the near future :)

Sam, the dyno numbers are amazing. Is reliability going to be an issue for those of us that daily drive our Z's?

:iagree: biggest factor for me...


is stg 1 or stg 2 any more or less reliable? given if i shot for the same 415whp with either kit?

Great results Sam:tup: Any vvel control updates? Will u be releasing it soon?

One thing at a time, jk lol I'm already saving, incredi-car here I come ;)

Sam

numbers are great.

Cant wait to see the car 2tm.

I'm not sure what car you're seeing tomorrow , but Sure.

Sam

We have Way too many things going on right now, the VVEl will be next to finalize after finishing the stg 2 SC .

Sam

So much awesome, great work on getting the kit done as this is the best news I have seen yet! Time to get serious about building up the car mod piggy bank. :tiphat:


How much work is it to install the new poly engine mounts?

Also need to order that part we talk about over the phone.

No problem, just was not sure what you meant, will see you tomorrow. :tup:

Sam

So I'm guessing these results were from dixon's car. Was the FX37 used in the 370z's kit development, also were there 2 oil coolers in that vid?

Will this SC2 kit be required to change any stock material besides adding an oil cooler?

Congrats on the results. Good job guys!

A new clutch

Congrats on the results Sam! 450WHP is what I wanted out of the S/C kit and now it looks like there is a clear path to get there. That TQ curve is phenomenal.

Just when I was going to give up on the stage 2... This happens :)

Are the dyno charts from the stage1 at 8lbs of boost?

Yes it is .

Sam

Can someone please explain to me what is stiffer motor mounts? how its a nice upgrade??

They allow for the engine to move less when the engine tries to twist itself on the motor mounts due to urethane being a harder material. It will allow for slightly better engine response as there is no movement allowed when compared to the softer and thicker rubber stock mounts.


Does anyone know how big of a job is it to install new motor mounts?

Prob not that hard since it'll be put in at the same time as the stage.2 kit

How about a stage 1 @ 10psi if possible or a Stage 2 at 8psi to compare apples to apples...the way you have this comparison laid out doesn't make sense.
