GTM Performance Engineering: VQ37VHR Twin Supercharger System

SAM@GTM · 09-14-2012, 11:46 AM

A little clarification. The car made 480whp, 360wtq on the first pull. In my opinion this is very good results for a new system on 91 octane and on a simple base map. Keep in mind that the ultimate goal right now is to stabilize the car and make sure that everything is functioning correctly. The system is far from done. So far all we have is about 7 - 9 dyno pulls since we are looking into VVEL lift variation between bank 1 and bank 2. This VVEL issue is definitely separate from the Twin Supercharger as the system is very unobtrusive and the VVEL system is not touched during installation. Also, having a VVEL code means that the engine is not running properly and is not ingesting air like should.

Right now, our main focus is ensuring that the system works properly and that this VVEL code is resolved. Once that is taken care of, we will be working on getting the power and torque. For now, that is not our primary concern.
