Hi Performance Specialists
What's New
 

1997-2001 C-5 Corvette Procharger Installation:

If your thinking of upgrading the performance of your late model vette, be sure to read our review, results and see our installation procedure of a Procharger P1-SC supercharger. In this installation we clearly lay out the facts about why bolt on simply is just a term and not reality. Check out the following steps necessary in order to bring your stock ls1 c-5 into a proven and reliable addition to the 500-rwhp club.

Just your typical late model extremely cramped engine bay waiting to be carefully manipulated in order to fit our procharger kit.

As you can see there just isn’t the most abundant amount of room to work here and even when things are apart its still cramped.

In this picture we have dropped the k frame down from the car for keying of the crank. Notice the mandatory use of a lift and two jacks to support what we don’t want to completely remove. We wouldn’t recommend trying this is your driveway.

In this picture we are looking at our balancer. Unlike typical small block chevys the ls1 motor is zero balanced requiring no extra weight added to the harmonic balancer. Therefore GM decided it was not a requirement to key the crank and balancer. This presents us with having to do so. The supercharger will require an amount of power to be driven and therefore as it runs off the present serpentine belt system we must lock the balancer in place by keying. Otherwise the balancer would simply spin on the crankshaft from no key way. In this picture we have installed a custom device that gives us the ability to perform said tasks in an appropriate fashion.

Here is an unlikely procedure for a general enthusiast to attempt. However this is a standard situation we are commonly presented with on a daily basis. Our technician drills the correct size hole, the correct depth in between the crank and balancer. This enables us to install the key way and prevent the balancer from moving. Careful consideration must be made to the fact this is a very expensive car and engine that we will not make mistakes on.

Final assembly of the head unit and idler pulley are made before it is bolted to the cylinder head. We make thorough visual and mechanical inspections of any parts before they are installed. Manufacturing has its flaws and we take no chances on any project. If there is even a slight issue, we feel necessary to find a resolution immediately to insure quality.

Here is our head unit just after installation. Fitment is very well designed for such cramped quarters.

This is a view of the passenger side intercooler from behind the k-frame. The original brake ducting has been removed to accommodate our intercoolers with fresh air first. Then we reinstall aftermarket ducting back to the brakes. Excellent ambient air is available in this configuration to ensure average 100-degree inlet temps at full boost on a 60-degree day. Note that this kit uses twin intercoolers that are routed at either side of the car left and right behind the front bumper.

Driver’s side intercooler and new fan assembly. The ducting and tubing on these kits is well engineered for such tight constraints. At far right you can see the new air filter assembly.

Here are some of the various tubes, hoses, and other miscellaneous parts involved.

This is a view of the bypass system located behind the radiator. The bypass system releases pressure in between the supercharger and the throttle body to avoid impeller and throttle body damage from the high airflows and pressure associated with supercharging.
