Speed parts have never been easier to find, or cheaper to buy in the grand scheme of things, and everyone is always interested in finding out how much horsepower you can make with a cheap chinese turbo or some other cheap speed part. This test video from Richard Holdener is pitting the junkyard M90 Supercharger up against the Cheap Ebay Turbo to see which one is the best powerhouse on a 4.8L LS engine. It’s cool, but they are way different, so watch and see which power and torque curve you think is best for your ride.
Video Description:
TORQUE FOR TOWING, WHAT WORKS BETTER, A BLOWER OR TURBO? WHAT IS BEST FOR TOWING? WAHT IS BEST FOR PERFORMANCE? HOW MUCH POWER WILL A CHEAP, EBAY TURBO MAKE? HOW MUCH POWER WILL A CHEAP, JUNKYARD M90 BLOWER MAKE? SHOULD I RUN A BLOWER OR TURBO FOR TOWING? WHICH ONE MAKES IMMEDIATE BOOST? WHICH ONE MAKE THE MOST HP PER PSI OF BOOST? CHECK OUT THIS VIDEO WHERE I COMPARED TO SIMILAR 4.8L MOTORS ON THE ENGINE DYNO. ONE WAS EQUIPPED WITH A GEN 5 EATON M90 BLOWER FROM A 3800 V6. THE OTHER WAS EQUIPPED WITH A GT45 TURBO. BOTH NA MOTOR MADE THE SAME PEAK NA POWER, AND BOTH WERE RUN AT THE SAME BOOST LEVEL. THE POWER CURVES WERE DECIDEDLY DIFFERENT. PICK THE ONE YOU WANT.
