This 2011 Chevy Silverado initially arrived with its 434 LS non-operational, and the customer was looking to have it fixed. After a few days of diagnosis, the pushrod turned out to be the main culprit. Due to the pushrod length being too long, the valves would not seal properly and essentially lose its compression in the combustion chamber.
After getting the 434 running again, along with a few other small fixes, the customer wanted additional range of services for their truck.
To clean up the engine bay, we've ripped out the entire engine harness to get our tucked n' loomed service, making the Holley high ram intake shine without the frail, crumbling OE harness surrounding it.
The nitrous system then got a similar service by relocating the nitrous solenoids and running new lines. The wiring had also been loomed to keep a consistent, out of sight look. Setting the nitrous up for 100 wet shot.
Though the truck already was equipped with a velocity stack, it still retained its MAF sensor. By request of the owner, we've deleted the MAF sensor and tuned the truck with speed density. Eliminating the risk of the MAF sensor reading inaccurately during driving conditions due to its unusual intake pipe design.
Next, the fuel system received an overhaul to take into account for the nitrous system. Eliminating the previous dual in-tank fuel pumps. With the sump at the bottom of the factory fuel tank, it eliminates any chance of air being caught during low fuel/high G situations. Deatschwerks 10- and 100-micron filters have been installed before and after the fuel pump.
Lastly, a few other engine dress-up options such as new battery cables/terminals, Alternator/Power Steering ICT Billet bracket, and removal of old modules, relays, and wiring that was no longer in use and cluttering up the engine bay.
We've also installed our dual catch-can with AN bungs welded directly to each valve cover. running it in line with the tucked/loomed harness.
Lastly, the exhaust was reworked to receive an x-pipe along with the trending muffler kit from Valvetronic Designs, the Truck/SUV Muffler. Giving the owner control when the truck can be loud, and when it can be quiet.
