600+ Rear Wheel SOHO A2A 370Z On Pump!

Nik@SOHO

Not sure if I should be flattered or scared with you checking on how many times I logged on today

My apologies as we have a number of clients to attend to during the day and do not have a lot of free time to post on the forums...

In regards to your statement above about the supercharger being overspun

The boost pulley that we are using is 80mm and the pulleys behind the head unit are 82mm ( my apologies if I assumed that you had the same setup on your kit)

The calculator that a lot of people use from vortech still has a lot of things that are not taken into account, so there is some margin of error.

Even still based on the pulleys used, we would "technically" be overspinning it based off of the calculation below however it is a very marginal amount:



Based on the other calculator that vortech offers this is what you get:



If you look at the graph for the 600 hp, our client makes peak power around 7500 rpm and then the power tends to taper off ever so slightly, it is not like this client is holding the supercharger at 7500+ rpm over an extended period of time.

We have a number of clients that run this setup and have not had any issues that resulted in a failed supercharger head unit or engine.

Thermal dynamics and efficiency have a lot of to do in our kit as to why we are able to make power. I even have a client here that switched from the intercooler that you supply in your air to air kit and went to ours and picked up a good amount of power running the Sci blower head unit.



This client is an automatic G37 sedan running the 9 psi pulley and turbo guard setup on E85.

I appreciate your attention to every aspect of our kit and for all the questions that you have asked, hopefully we have answered them for you and have been able to help make the Nissan community a more informed group
