Nissan 370Z Forum - View Single Post - GTM Stage 2 Supercharger Preliminary Testing Results

SAM@GTM · 05-16-2011, 05:43 PM

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!
