1997-2004 5.7 Liter C5 Corvette Supercharger Systems

With the ECS C5 Supercharger System, You get more. A lot more. This is the kit that has helped set several national C5 records in both 1/4 mile and 1/2 mile racing and has proven itself for thousands of miles on Corvettes around the world.

It is the most complete system in the market. It was designed to work with your factory cooling system, and retains provision for factory, or after market oil coolers. We include things that greatly add to reliability such as heavy duty belt tensioners and steel double bearing idlers, as well as stainless steel hardware, high quality silicone hoses and high grade, stainless steel t-bolt clamps. All things, that are more often than not, considered upgrades by competitors.

A Superior Belt System

alt


When you install a SC System on your C5, you dramatically increase the load on the vehicles belt system. That’s why we start our C5 system by addressing one of the most critical aspects of a centrifugal supercharging system – not addressed by other SC manufacturers. We start by including a super strong, custom belt tensioner designed, specifically, to handle the increased belt load. We go further by providing zinc coated steel, double walled ball bearing idlers to replace the factory plastic idlers that are expected to handle the belt load in lesser systems.

Strong and Functional Brackets

alt


ECS uses a proprietary bracket system that provides the most belt wrap possible, while still being user friendly enough to enable easy and fast belt changes when necessary. Other systems will require you hours of additional labor to pull the head unit to perform a simple belt change. The ECS brackets are made in house from 3/4 in billet aluminum and include steel idlers along with a stout slide idler, allowing maximum belt wrap and traction.

The Highest Efficiency Intercooler

alt

The C5 Corvette is a “front breather”. Meaning all the air that cools your radiator and AC condenser passes through the nose of the car. That’s why ECS started from scratch when designing our intercooler. The large 17 x 3.5 x 8 in core has proven to support more than 1000 hp, and still provides adequate airflow across the front of the car to allow your AC and cooling systems to keep the car operating as it should, without the added cost of a larger radiator and fans. With the ECS intercooler you won’t need to scoop additional air from the bottom of the car in the attempt to manage heat. Doing this only causes lift on the nose of the car and disturbs the air flow as it was designed in the C5. The Intercooler features a 3 inch inlet and a 4 inch outlet to maximize cooling and airflow that so critical to your supercharged Corvette.

Top Rate Materials

At ECS we believe that quality is in the details… that’s why all we use the top materials… stainless steel hardware, brand new flow matched injectors, zinc coated steel idlers, 6061 aluminum ducting, stainless steel t-bolt hose clamps, high quality 4 ply silicone hoses, lifetime air filters…. Other kits in the market will use modified stock injectors, plastic idlers, factory belt tensioners, steel ducting,  and lesser quality materials, then give you options that are available to cure a known issue or present revision after revision to try and offset shortcomings in design. At ECS we do our best to do it right the first time. Not offer revision after revision in an attempt resolve known shortcomings in design.

The Paxton Novi 1500 has been the core of our C5 system for a number of years. This head unit features a self contained oiling system, and super quiet operation making it the top option for most customers. While many customers choose the ECS Supercharging System for its unmatched features and reliability, others choose the ECS Package because it presents far more growth potential that any other supercharging system for the Corvette. Almost any system can deliver 500 rwhp on a factory LS1/LS6, but how many of them can exceed 700rwhp? ECS can.

Possibly the best feature of the Novi 1500, is the scalable power it provides. It will provide 500-600 rear wheel horsepower on otherwise stock C5’s, but when uncorked, it can provide enough boost to generate more than 800 rear wheel horsepower on a properly set up engine. Other manufacturers start off with less expensive, and smaller head units that don’t present nearly the power output of the Novi 1500 leaving you in a situation that when you want more power, you will need to purchase a completely new head unit ($3000+) or a blower cam package ($2500+) to come close to the power the base ECS kit provides.

If you are looking to support above what our base Novi 1500 can support, our bracket system is compatible with several Novi head units to support upwards of 1,300+ whp depending on the application. Our brackets will work with the following head units:

Novi 1500-SL

Novi 2200-HD*

Novi 2200-R*

Novi 2200-X*

*Oil fed units require -4AN feed line and 1/2" or -8AN drain line

All available in Black or Polished finishes.
