Preparation for the STILLEN supercharger

LiquidZ

Stillen, what HP level did your engineers design the intercooler for? GTM's is up to 700 hp.

I'm just trying to get an idea for future expansion, if needed.

It's kind of hard to answer that question.

An air to air intercooler can pretty easily be rated to a certain amount of horsepower because you can measure the volume of air traveling through it efficiently.

However, with an air to water intercooler setup there are a few other things to consider. In the packaged standard form that the kit comes to you with no modifications, you can expect to support around 600 horsepower or so. However, if you decided to modify the system with a few minor little changes, you can support even more. An old trick used by many drag racers is to pack the coolant reservoir with ice. Obviously this chills off the water even further thus improving the efficiency even more.

Another option is to upgrade to a larger heat exchanger so that you can cool off the coolant longer thus lowering the temperatures further.

Because there are so many different things that can be done with an air to water intercooler we can't really put a blanket number on how much horsepower the intercooler can support efficiently.

What I can say is that we are using a heat exchanger which is larger than the heat exchanger that Magnusson supercharger's uses on their kit for the Corvette's.

How much horsepower do you want and what do you plan on doing with the car? Is this going to be street only? Road Course car? Drag racer? Dyno queen?
