Gen-TT Truck Systems The latest member of our fleet, a GM truck to form the basis of our new Gen-TT intercooled twin turbo system 
For those that want to know the specs, the car (truck?) is a 2002 Silverado 1500 series of the short wheelbase kind. With a full fibreglass back section its not as heavy as you might think either which will mean lots of tyre smoking twin turbocharged fun
The engine is a 5.3 litre version of the LS1 with that familiar looking big truck manifold and a fly by wire throttle body. There is some extreme torque management in there to protect the driveline, but still she pushed out 245rwhp on the obligatory 'before' run....now its time to get SERIOUS
We will keep you guys updated over the next couple of weeks as we get the first prototype kit out there and testing

Another benefit of using these turbochargers is that we have already proven their torque response on all of the LSX family from the LS1 through to the L98 and LS2. One of their major characteristics (when used in tandem) is a massive torque peak at around 3500rpm, which we consider to be a valuable asset to truck performance and getting that big body moving quickly. Here is a dyno of a pair of 2833 turbochargers on an LS2 running 9psi boost pressure
The 620 torque interests us much more than the 520rwhp as the torque numbers is the key to getting strong acceleration when you are pushing a big brick through the air
interested in this as well. and i didnt know a 02 pick up had DBW but also never seen a non-USA one. but my question is, would you be doing an upgraded turbo setup for this? reason i ask is say if one had larger cubes like a 408. all piping the same but would need larger turbos

Some progress shots from today with the truck fully stripped down for inspection and analysis. There isnt a whole lot of room on these trucks for turbochargers in the engine bay without seriously increasing the underbonnet heat loading, which in a Tow/Haul situation might not be the best solution
After assessing all of our options we have decided to place the intercooler low behind the front lip on a 45 degree angle with a specific air duct, so that it gets plenty of frontal air flow but doesnt block the trucks basic cooling system

well its about time.. one issue though.. us US guys ac is set up ALL different with the compressore on the (well our) pass side evap as well.. so how are you guys going to figure this out.. i got an idea.. get it all moched up.. send it to me.. i'll pay shipping.. and tell you how it fits.. 
oh yeah and in the us 02 wasn't drive by wire..

The kit will be fitted to both 1500 series and 2500 series/4WD to check for accurate fitment on all models before its signed off as production ready
We just changed the intercooler on my neighbor's Escalade from something similar to yours to a different IC mounted in front of the radiator. The nearly flat low mount did not cool worth a ****. Even if it costs a little more, or involves cutting, you should really change it. In the case of the Escalade, the change was worth over 20*F cruising and close to 50*F better at the end of a 1/4 run. This was on a Livernois kit with a single 67mm.
