East Coast Supercharging 1997-2004 5.7 Liter C5 Corvette Supercharger Systems
With the ECS C5 Supercharger System, you get a system designed to work with your factory cooling system, and retains provision for factory, or after market oil coolers. Including 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 on some other systems.
Belt System
When you install a SC System on your C5, you dramatically increase the load on the vehicles belt system. That’s why they start their C5 system by addressing one of the most critical aspects of a centrifugal supercharging system – not addressed by some other SC manufacturers. Including a super strong, custom belt tensioner designed, specifically, to handle the increased belt load 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
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. 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
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
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.
Head Unit Options
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:

Let customers speak for us
from 50 reviewsBought the alternator for looks and it sure does it look beautiful! Also keeping my voltage up right where it needs to be with all my LED lights and upgraded sound system. would definitely recommend this alternator to anyone.

I don’t have one complaint about the Neomax coilovers.
Have them on my c6z. They ride great just cruising, they work very well on an autocross course, and the launch at the drag strip feels much better than the transverse leafs. I will be purchasing another set for my swapped c5 drag car. Also Brian has impeccable customer service and is very knowledgeable.

After about 100 miles of daily driving so far these coilovers feel even better than the stock suspension did I went with the 12k fronts and 10k rears

Great product and service from Brian

I just drove the car for the first time since installing and even on cold roads and little adjustment they are a night and day difference from the factory leaf springs. Car is a higher hp nitrous car and these are exactly what it needed. Can't wait to see what they can do with some adjustment and tuning. If you're on the fence about getting them just do it you won't regret it.

Kit looks great can't wait to install. Don't forget to add the Wilwood stainless brake line kit to get the best performance.The best part was the service Brain gave with this purchase. I would recommend FI Performance to anyone looking for great prices and wonderful customer service. What other performance parts site do you know where the owner himself will contact a first time customer and walk him through the options available?

You really do get what you pay for with these. Steering feels sharper and smooth. Weight shifts feel smooth and planted. Ride is nice and comfortable but tightens up when you need it to. Build quality is also super great. Nice and sturdy with quality materials. Genuinely satisfied with how easy the entire process was from ordering,shipping and installing these coilovers. Will definitely be recommending this suspension with all of my bmw friends on discord 👍 shoutout to Brian for helping me throughout this entire process

ECS Corvette C5 Automatic Trans / Rear Diff Brace

Installed these on my 2012 c6 and it definitely feels 100x better to drive than the stock leaf spring setup. Install wasn’t bad… it’s just bolts. Brain reached out after purchasing to go over the order and make sure its exactly what I wanted, I was very surprised, awesome customer service. All in all great product and service!

Great upgrade to the old worn out leaf springs. Feels like a modern suspension now. Excellent quality and workmanship. Definitely recommend

Great communication and fast shipping!!! Brian is quite knowledgeable! Let him know your set up and he’ll get you connected with the right product!

A+ Thanks!

Never fail, feel great! Pair with swift springs and you’re riding on a magic carpet ride. Makes all the hunnies holla when you’re cruising down the street in my c6.
