A nice daily cruiser, this CTS-V put down 456 rwhp & 464 ft/lbs during a summer baseline. We kept it simple for this build – knowing that a few small upgrades would go a long way in performance and feel, without impacting driveability. We chose an Air Aid CTS-V intake, 160 thermostat, and upgraded the supercharger pulley to Lingenfelter’s 2.55 set up, with the 10 bolt hub for easy changing later on. We backed up the additional power with a set of FIC 1000cc injectors to cover the fuel side. After install and tuning, the car put down 532 rwhp & 519 ft/lbs tq – making for a gain of 76rwhp and 55 ft/lbs tq!
“As expected, just the stage 1 makes a BIG difference in how it comes on all the way thru the rev range, but especially in the mid to upper rev area. That’s at 100 degrees today !!! I can’t wait to try it tomorrow morning when it makes it down to 75 degrees. Come this winter when the temps get down in the 50 to 60 degree range, I’ll definitely have to be more careful than in the past. Awesome improvement.”
When this 2011 CTS-V’s stock engine met its demise through lost oil pressure, our customer decided to build it bigger and badder! Starting with a 418ci block from Texas Speed, we topped it off with a set of 280cc ported and polished heads from Advanced Induction, using Brian Tooley Platinum Valve springs. We also custom spec’d a cam to take advantage of the larger cubic inches.
This build also features an upper and lower pulley set up from Lingenfelter, allowing us to obtain as much boost as possible. We used Fuel Injector Connection 1000cc injectors and an MSD Boost a Pump to cover the fuel situation. For better cooling, we swapped the stock CTS supercharger lid for a ZL1’s, which has a larger cooling brick (not to mention looks better also!).
A melling 10296 oil pump was installed, along with a COMP Trunion Upgrade. We used Kooks for the exhaust – running their 1 7/8″ headers with catted connection pipes. After dyno tuning, the car laid down a whopping 725 rwhp & 704 ft/lbs of torque. Definition of ultimate sleeper? We think so!
It seems like we can’t get enough of the LSA’s lately, and this was no exception! This automatic 2009 model’s owner was looking for some subtle upgrades – better performance and responsiveness – without sacrificing any of the car’s driveability or stealth.
We kept it simple for this ride – adding an AirAid intake, 160 degree thermostat, a Lingenfelter upper pulley set up, 1000cc injectors, and of course tuning to go along with it. With the 465 rwhp & 479 ft/lbs tq it baselined at this car felt great – but it felt even better once we added another 70 to the rear wheels – ending up at 535 rwhp & 514 ft/lbs tq!
These simple packages make a big difference in these sleepers, without sacrificing the luxury of driving a Cadillac. The tuning especially helps to improve the 6L80e’s transmission shifting, which leaves a lot to be desired from the factory. Overall a great bang for the buck.
Looking for a simple upgrade or two to help make wake up this factory CTS-V, we suggested our Stage 1 Package, which consists of a cold air intake, thermostat, and dyno tuning. We offer a few different types of intakes, but chose an Air Aid for this particular build.
We started by baselining this vehicle, putting down 453 rwhp & 467 ft/lbs tq. A few hours later after these simple upgrades, we were up to 529 rwhp & 509 ft/lbs of tq, making for a gain of 76 rwhp & 46 ft/lbs tq! Being an automatic, we also were able to greatly improve the transmission shifting as well, making the car even more enjoyable to drive!
While this customer knew that his CTS was a really quick ride right out of the box, eventually he was wanting more. He was looking to add more power and get up and go without compromising driveability, so we went with our Stage 2.5 CTS-V Package. This includes a cold air intake, Kooks 1 7/8″ Headers with cats, and adding boost back with a larger lower pulley utilizing Lingenfelter’s balancer kit.
Our baseline dyno showed the car at 490rwhp and 470 ft/lbs tq, pretty typical numbers for a manual CTS in the summer time. With our additions and a modest 12lbs of boost, we ended up at 572 rwhp & 581 ft/lbs tq, making a gain of 82rwhp & 111 ft/lbts of tq. The CTS-V ended up with a better sound and felt a LOT better off the line!
“I love the CTS – THANK YOU!!!”
Feeling the need to upgrade this 2011 Automatic LSA CTS-V’s 489 rwhp, this customer sought us out to install our LSA Performance Package One (available HERE) which includes three simple upgrades – a 160 degree thermostat, a cold air intake, and a dyno tune. In the matter of just a few hours, we were able to find another 50rwhp with these simple upgrades, ending up at 539rwhp and 499 ft/lbs tq! During our dyno tune and final road tuning, we also spent a lot of time tweaking the shift pattern of the 6L80e transmission, which needs a lot of help from its factory settings. Between the new shift patterns and added horsepower, this CTS-V was like a whole new car for less than a grand!
