    2005 Cadillac CTSV – Camshaft

    I like big lobes and I cannot lie!

    Casey decided he needed some more grunt from his bolt-on 2005 Cadillac CTS-V… so, the next logical step?

    More bump stick! James set this LS6 up with a BTRIII camshaft and supporting valve train components from Brian Tooley Racing, along the other supporting modifications. After the installation was wrapped in the shop, the V1 hit the rollers to get dialed in by Dan via HP Tuners.

    Once complete, Dan had the LS6 laying down 390.54whp & 361.74lbft. If you hear a ground-pounding chop at the stoplights, keep an eye out for this Corvette-DNA Cadillac!

  • 2012 Cadillac CTSV – Headers

    James brought his beautiful Black Diamond 2012 Cadillac CTS-V in for the next round of modifications! Back in December of 2016, James brought us his then stock V2 (aside from the CORSA intake) for a Lingenfelter Performance Engineering 2.55″ upper pulley, solid isolator, and 160° thermostat, AFCO Racing heat exchanger, VariMax intercooler pump, Big 3 Racing intercooler reservoir, Injector Dynamics ID850 fuel injectors, and a custom calibration by Vlad via HP Tuners — the result was 547.83whp & 540.15lbft, gaining 104.40whp & 88.75lbft over baseline!

    Since then, he’s gotten that itch for more, so now he’s back to take it up a notch! This round, John installed a set of Stainless Works long-tube headers & full exhaust system, stepped one pulley size down to a ZPE Griptech 2.45″ upper pulley, and then Vlad dialed her back in via HP Tuners — the results were exactly what we were gunning for: 617.89whp & 619.39lbft, a gain of 70.04whp & 79.24lbft!

    ~620whp/620lbft should definitely keep James pinned to the seat and grinning for a while, but knowing him, we’re sure to see back in a year or so for the next steps!

  • 2013 Cadillac CTSV – Intercooler & Tune

    Jason just picked up this beautiful MT6 Thunder Gray ChromaFlair 2013 Cadillac CTS-V, and brought it in because it felt a little down on power. Upon investigation, we discovered two things: one, power was definitely off for the modifications performed, laying down only 536whp/542lbft. That, and with IAT2s at nearly 200° F, we knew what must be going on: collapsed intercooler brick, which we verified shortly thereafter.

    Once we installed the repaired/reinforced intercooler brick, power came up to 575/565lbft, and then after dialing in the calibration via HP Tuners, power jumped to 633whp/639lbft! 97whp/97lbft gain from correcting a cooling deficiency, and a performing a proper calibration. Wild results!

    Two, this V is sitting on a set of reworked OEM wheels — the exact setup which we pioneered back in 2010! This basically entails widening the front wheels to run on the rear, moving the rears up front, and all the bits-and-pieces necessary to execute. Check out the original build thread from 2010: https://ls1tech.com/…/1280217-national-speed-2009-cadillac-…

    Overall a killer car, and fantastic results!
