Joseph’s 2011 Cadillac CTS-V rolled into the shop as an engine-less shell, with boxes of engine parts in the trunk, and a simple guiding goal: build his V2 into a reliable 700whp+ daily driver.
So, we inventoried what we had to work with, filled in the gaps, and turned this V2 into a street-prowling beast! The build is centered around a Steve Morris Engines built 377cid/6.2L LSA-based short block with a bump in compression ratio to 10:1, Melling Performance Parts oil pump, stock unported cylinder heads, ARP cylinder head studs, custom 3-bolt conversion camshaft from Cam Motion, valve train from Total Engine Airflow, COMP Cams, and Brian Tooley Racing, Jokerz performance ported OEM LSA 1.9L supercharger, ZPE GripTec 2.55″ upper supercharger pulley driven by a Lingenfelter Performance Engineering 9.55″ lower, OEM Camaro ZL1 supercharger lid with a Dedicated Motorsports reinforced intercooler brick, AFCO Racing heat exchanger, Aldo Welds trunk-mounted intercooler coolant tank, breathing in through an AIRAID intake system & OEM LS7 throttle body, with a Mightymouse Solutions catch can delivering clean air, breathing out through a set of Kooks Headers and Exhaust long-tube headers, with fueling provided via DSX Tuning auxiliary fuel pump & Flex Fuel conversion, Injector Dynamics ID1050X fuel injectors, and all the OEM GM & aftermarket odds-and-ends to bring it all together.
Once the mechanical work wrapped in the shop, Charlie strapped her down to the rollers for Vlad to perform a custom Flex Fuel calibration via HP Tuners, coming in at a strong 753.35whp & 721.20lbft on E85! Pound-for-pound, it is hard to beat a well-built 750whp V2 for a daily driver.
