I have received a lot of emails, dm's on this since it was being talked about but not released. This is an amazing system. I have had it in my car for months running tests and I am so pleased to share this info. It is a game changer for anyone who like to keep things as close to factory as possible by having enough fuel to support more HP than the motor can ever produce. For E85 guys this is a win win. We have mocked this up on my car. This is a plug and play system. This kit comes with a various array of pump selections. i opted for the twin Walbro Hellcat 525 pumps. The new hanger design is absolutely brilliant. The R&D that went into this system was well thought out. The pumps have to be installed inside the tank in stages due to it's size in the factory gas tank. Once installed the pumps are no louder than a factory pump. No noise, no humming, no insulating, no nothing. Just massive amounts of fuel at your disposal which retains all the factory features like your fuel gauge in the instrument cluster. This system depending on voltage of your Buick will support north of 1,600hp. No fuel controllers are needed.. My pump gas and alky setup is currently around 850hp to the tire with a 48% duty cycle on one pump with a 160lb injector on 94 octane pump gas, with the voltage logged at 13.6.
