Anthony Cobergs 07 Corvette with APS twin turbochargers
This update from: 07/07/2007

Anthony has an 2007 Corvette convertible that is soon to have the power to match it's awesome looks! Anthony brought with him a new APS twin turbo system, for us to install. From our experience with an APS ttwin turbo kit on an 06 GTO, this C6 is going to be a handful when we are done with it!
The first thing we are doing is upgrading the clutch, as the stock clutch was not going to be up to the task of handling the amount of torque this engine is going to be producing.



We removed the transmission assembly from the chassis to switch out the clutch and pressure plate and the new steel flywheel assembly.



There is nothing better than having new sheetmetal to work with!



We are installing a Spec Stage 3+ clutch, pressure plate and flywheel.
With a full face design for smooth engagement, and an 800 ft lb torque rating, these clutches have proven themselves for us.



We added an Autometer boost gauge and an AEM wide band into an Autometer pillar pod. The wide band is very useful in making sure the air/fuel ratio stays where it needs to be.



The clutch is installed, now on to the APS Twin Turbo System.  We were pleasantly surprised to find the heat shielding already installed on the manifolds. We had to install these shields on the APS twin turbo GTO kit we installed. The turbos came already installed on the manifolds, another nice touch! These APS kits are of the finest quality we have come across!





Nothing but gleaming APS quality here!



The intake manifold had to be removed to put on an oil sender on the back of the block. This isn't hard to do, and the instructions are very good.



The turbos tuck up very well and plenty of heat shields came with the kit.



We did install on our own a DEI Starter Blanket, just to ensure the starter stays cool. The starter blanket can be seen towards the top of the picture.



Here is a good view of the passenger side turbo and plumbing.
Everything is tucked up out of the way on this APS kit.



The air filters are located just in front of each front tire.



The passenger side APS intercooler can be seen here.



An MSD part number 2350 Fuel Pump Booster is included with the APS twin turbo kit. We have used the MSD fuel pump booster in many of our own installations, and it works very well.



The APS supplied exhaust manifolds are very thick, which is a good thing, as they have to support the weight of the turbo's. We have found turbo mounts to be the number one failure on turbo kits, and this APS manifold looks to be up to handling the weight and the extreme heat cycles that will have to be endured.



Here is a view of the engine compartment, the APS twin turbo kit looks as if it could of been a factory option!  



Anthony has a Corsa exhaust system on his C6, which looks great!



This C6 is now up on our dyno!



537 rwhp and 547 ft lbs of torque, not bad for a hot and steamy day on a Mustang Chassis Dyno!
The average amount of boost is 6.1 psi, with a max of 7.1 psi.





All finished and ready to blow a few unsuspecting cars into the weeds!
This Corvette makes 400 ft lbs of torque on our Mustang Chassis Dyno at only 2500 rpm!
APS definately produces the best turbo kits we have installed. They may be relative newcomers into our domestic market, but they have been producing turbo kits for the import market for many years. As far as turbo kits go, APS is the only one we would recommend.
