HOW DO I MAKE MORE TORQUE WITH MY GEN 7 8.1L BIG BLOCK? CAN I RUN A CHEAP TURBO ON MY 8.1L GEN 7 BIG BLOCK? IS THE GEN 7 BIG BLOCK REALLY AS LS? HOW MUCH BOOST CAN I RUN? HOW MUCH BOOST WILL THE STOCK 8.1L TAKE? WHAT SIZE TURBO SHOULD I USE ON MY 8.1L BIG BLOCK? DOES THE SUMMIT RACING S475 TURBO REALLY WORK? CAN I RUN E85 ON MY TURBO BIG BLOCK? CHECK OUT THIS TEST ON A HIGH-MILEAGE, JUNKYARD, GEN 7, 8.1L BIG BLOCK WITH BOOST. I ADDED AN S475 (T60 TURBO FROM SUMMIT RACING TO THE USED 8.1L (THNX AGAIN AMOS AND DARREN). RUNNING E85 FUEL AND AN ATW INTERCOOLER, I SUCCESSFULLY TURBOCHARGED THE JUNKYARD BIG BLOCK AND MADE SOME IMPRESSIVE TORQUE AND POWER GAINS!
