Alcohol injected, supercharged, forged GM LS6 (5.7 ltr. / 346 ci) with forced induction provided by an intercooled, oil injected, Paxton Novi 2000 Supercharger running at 18 psi (with a TiAL 50mm BOV & 9 psi spring) on an 8-rib belt setup (using a 3.25” head unit pulley); fed by an AlkyControl dual nozzle methanol injection system, controlled by a PAC progressive regulator and 2 Bar GM MAP sensor. The methanol system pressurizes at 4psi of manifold air pressure and continues progressive injection through full boost. Secondary fuel supply is provided through a Bosch inline pump that is activated by a Hobbs Switch at 4psi of boost and delivered through an ECS Custom Fuel System.

Although I do drive this car on a semi-regular basis, I try to keep it as clean as I can. So, I also drive a 2003 Dodge Ram 2500 SWB Quad-Cab with a Hemi and a few, minor mods as well as our 2006 Subaru Legacy GT. But, I love just about anything with an engine in it and recently sold some other toys that I just did not have enough time to use, but I loved em, including a Four Winns 258 Vista (boat), a Yahama Vmax street bike, a Yamaha YZ250 motocrosser and a Kawasaki Ultra 150 jetski. But, I always wanted a Corvette and this car has been a dream to own, drive and enjoy. I’ve also made some good friends just by taking her to a few local car shows / cruise-ins, charitable events, rallies, drag races, etc. I even had the local high school print shop class create a car-show poster for me, which I thought was really nice. I'm now getting more involved in drag racing and competing for points in the CC Pro 10 double index class.
