All this talk about the Guru, I went out and bought one, well sorta. I went out and ordered a Paxton NOVI-1000 Supercharger kit for my "Black Bullet". This kit has the works, it produces 6-7 psig of boost. Fuel System upgrade includes auxilary injectors and electronic fuel/timing control box. The aluminum discharge tube provides high strength and good looks. This systems also includes a billet aluminum mounting bracket, K&N air filter and all necessary hardware, plumbing and instructions. It was a bitch to hook up and the adapter was quite expensive. But I'll be willing to bet I'm the only one here who can have perfectly pulled pork in the 1/4 mile in under 8 sec's. Man the sound of the Flowmasters and the smell of pork, Oh Yeeaah!!
