Frequently Asked Questions -
Corvette Single Turbo Kit
Is this system a full kit?
Yes, we include or offer everything that is needed. The kits are offered in stages for your convenience. These can be modified for a custom package. Individual parts are available too. Please contact us regarding pricing on custom setups.
How much power can I make with this kit on the 62mm?
You can make up to 650 flywheel horsepower. We made 505 rwhp and 511 rwtq on a bone stock 01 Z06 motor. Fuel injectors and a pump upgrade are required. The stock fuel pump operating at stock voltage will provide fuel for 500rwhp. We estimate 515rwhp on a stock engine with an upgraded fuel system. More power would be possible with an alcohol injection system.
All fuel system upgrades including the alcohol injection are available through Hinson Motorsports. Ask for a fuel system package when placing your order.
How much power can I make with this kit on the upgraded 76mm?
The air/water intercooler used in the system will limit the engine to 775 flywheel horsepower. Going beyond this power level will require a larger intercooler.
To fully answer the question, a 76mm turbo can make 980 horsepower within its efficiency range. This turbo will accept a 98mm turbo which can make even more. The flange is a T4 style.
We can and will make an air to air intercooler system if requested in enough demand. This turbo system was optimized for the 62mm turbo. If there is a strong demand for a larger system, we can accommodate the community this year. More details will be available in early 2009.
What size down pipe (DP) is this?
Our kit uses a 3” DP. This is the largest DP that will fit without modification to the car.
How much power can I make on a 3” DP?
This DP is designed for a combination of power, performance and fitment without having to modify the chassis. On race applications, we have made over 1,000 rwhp using a 3” DP (not this kit). We are not suggesting a 3” DP for 1,000rwhp builds, but it will work when necessary.
How does the air to water intercooler work?
The W2A intercooler cools the air intake charge with cooler water. The process works the same as a radiator, but we are cooling the air in this configuration.
Our system pumps a coolant from a water tank under the passenger side headlight to the intercooler under the driver’s side headlight. The water/coolant passes through a heat exchanger after leaving the intercooler. The system circulates the fluid constantly.
What kind of water can I use?
Any type of water is fine. If you are going to be operating the car in a freezing environment, then you will need to add antifreeze. You can also use Evans Coolant for year round service. Evans coolant is available through us.
Can I add ice to the water?
Yes, adding ice will lower the air temperature dramatically and increase horsepower. A colder intake air temperature will make more horsepower. We strongly recommend this for drag racing.
Do I have to make any modifications to the car?
You will need to trim a small section of the hood for the compressor housing clearance. There is no affect to the outer painted skin.
What kind of fuel system should I run?
The most common configuration will be 60# injectors and a Walbro 255lph fuel pump. These parts are available through Hinson Motorsports.
If you are looking for a big horsepower setup, we can build a custom fuel system to meet your needs.
What kind of ground clearance will I have?
The ground clearance is not affected.
Is there any heat issues?
We used an air/water intercooler design over an air/air because it has less effect on the engine’s cooling systems. A common problem with forced induction C5s is higher engine coolant temperatures. The small heat exchanger mounted in front of the radiator blocks less air than a standard air to air (A2A) intercooler.
We found normal engine operating temperatures in our brutal southern climate using this system with no modification to the cooling system.
Should I use a turbo blanket or exhaust heat wrap?
We did not use a turbo blanket of exhaust wrap on our shop car throughout our testing. There has been no damage to the oil feel neck, hood, or electronics. However, your application may require additional protection. There is no reason not to wrap or coat your system.
We did wrap the rubber AC lines near the DP for better performance and longevity of that part. We recommend that you do the same.
Where is the water box located and how do I fill it?
It’s located underneath the passenger headlight. There is a removable cap on top large enough for ice. There is a drain cock under the tank.
Where is the intercooler located?
It’s located underneath the driver headlight.
Where is the heat exchanger located?
The heat exchanger is mounted in front of the radiator and at the lower edge.
What is the intended use of this kit?
This kit is intended for street, drag race, autocross, and light road racing applications.
The problem with long term road racing would be constantly rising air intake charge temperature. In a long session of road racing, an air to air system would be more efficient.
The above problem is not an issue with extended street driving sessions. The intercooler coolant is constantly exchanging heat with the air. The water cools hot air during a wide open throttle (WOT) run. The cooler ambient air cools the water during partial throttle runs and/or at idle.
Where is the air filter?
We have built a mold for the air filter neck. This mold slims down to fit between the bottom of the hood and the radiator cover. The mold expands to place the filter in front of the plastic radiator. Production of this piece has not been initiated as of 1/19/09. A judgment will be made soon on how to solve this issue.
Race applications do not require a filter. In the mean time, we are using a wire screen to protect the engine.
Can I keep my stock radiator expansion tank?
No. We use the BeCool expansion tank. This is available through us and can be purchased separately.
What is the projected installation time? 12hrs
Can I keep my fuel rail covers? Yes, the right side will need to be trimmed for DP clearance.
