RJ MFG Supercharger kit Feeler...

Well the Vortech V3 si trim is rated at 775bhp (50hp more than that c38) and we know that it is impossible to get that on the 370z. Even with overspinning, a huge fuel setup and E85 we are 125hp away from that mark. So the 725bhp rating on the c38 doesn't mean much.

Adding headers and built heads would help a little, but will this come in the kit?

I am not trying to put this idea down. Just make sure that if you bring a centri unit to the forum, it can actually make the power claims you stated instead of having a bunch of guys waiting for a system that leaves them deflated.

We are actually referencing their (c38 -91/92) compressor maps. We understand and made it noted that the limits would be topped out in the low to mid 600's. Increasing the volumetric efficiency of the motor is key. Plus guys have made mid 500's on GTM's kit on the smaller C38 - 81 units which is what GTM sold as the stage 2. The Stage 3 C38 - 91/92 was never sold publicly. One of our customers has the only STG 3 kit ever sold by GTM. Even then the C38 - 81 was not pushed to its limits. The limitation came with not having access to pulleys and transparency in their kit. They used cheap parts including their intercooler. We firmly believe the C38 - 91/92 supercharger has the capability to put a solid 550whp and reach into the low to mid 600's maxed out.

For the Vortech it is going to be debatable on which unit we would have to use based on space limitations. However, if we can fit it we are looking toward the V7 trim if it could fit... But there doesnt seem to be much of any interest in this platform.

When it comes down to it we need to focus on efficiency of the kit and the motor. The more efficient we can make both the more power there is to be had. Once we have tested our kit we will put out official numbers and our ratings will be conservative. We only want to sell what we know everyone will make.
