GTM Stage 2 Supercharger Preliminary Testing Results

SAM@GTM

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


07-07-2011 UPDATE

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!

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.

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

christian370z

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?

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

Possible to tag 500whp?

SAM@GTM

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.

Mr&Mrs

Very nice in for updates.

Z eliminator

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!

Mr.Squeeze

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

SAM@GTM

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

Mr.Squeeze

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