Every cam is a turbo cam, in the words of Richard Holdener himself, so if that is the case then how can you possibly make more than 100 extra horsepower from a cam swap on a junkyard LS turbo combo? Well while we all know that boost makes power, regardless of the camshaft, we also know that if you want to make the most of that boost then there are some real gains that can be had with the right camshaft. Watch the video below and see just how big those gains can be, and how they are affected by other parts. Check it out.

HOW MUCH IS A SIMPLE CAM SWAP REALLY WORTH ON A TURBO LS? CAN YOU REALLY GAIN 120+HP AT THE SAME BOOST LEVEL? CAM YOU MAKE 750 HP AT 11 PSI ON A JUNKYARD TURBO 5.3L LS? DO TURBO CAMS REALLY WORK? DO TURBO HEADERS MAKE MORE POWER THAN CAST EXHAUST MANIFOLDS? DOES BACK PRESSURE HURT POWER? DOES BACK PRESSURE IMPROVE TURBO RESPONSE? CHECK OUT THIS VIDEO WHERE I RAN A COMPARISON BETWEEN THE FACTORY LM7 5.3L CAM AND THE BRIAN TOOLEY RACING STAGE 2 TURBO CAM ON A SINGLE-TURBO, JUNKYARD 5.3L LS. I THEN COMPARED THE EFFECT ON POWER AND BACK PRESSURE BETWEEN THE HOLLEY CAST-IRON TURBO SYSTEM TO TUBULAR TURBO HEADERS.
