if you want some dyno numbers go buy an intercooler and get a dyno with it hooked up. and post it up.




if you are looking at cooler the air temp going into the motor just run a phenolic spacer. proven power and you drastically lower the upper intake for a little while until it obtains "room temp" of the enginebay but still maintains relatively cooler than the lower intake. since the upper intake would not be touching the lower via a metal heat transferring substrate it shall remain cooler longer giving you some more power at the cost of...25 bucks?



why do you want see evidence so badly of an intercooler ran n/a? im sure its been done before and it sucked...thats why its not a common mod since its a relatively inexpensive part.

It has happened before.

The thing is though that you're running intake temperatures that are barley different from the intercooler AND you're not running pressurized air which makes it exponentially harder to get through a restrictive intercooler, so if the fact that you can setup an intercooler to loose power exists on a charged car, it must be true that you'll lose power on a N/A car because you're giving it the worst possible chance for the gain to exceed the loss, in fact you're probably negating the existence of the gain part in the first place.

Air has to be pulled through the intercooler with Vaccum from the engines intake stroke. On each intake stroke the engine pulls the air through the intercooler. As the air moves through the intercooler it has to make several 90 degree turns. As the incoming air makes a 90 degree turn the air stalls as it hits the flat walls of the intercooler (much like exhaust hitting the inside of a muffler to quiet the sound) and bounces causing turbulance in the intercooler. The pulse waves of vacuum created by the engine just enhances the turbulance. Unless the passages in the intercooler were as large and as smooth flowing as the intake tract it's a restriction. In Blower applications it has to restrict flow somewhat so the air has a chance to cool inside the intercooler. When You run a Intercooler on a blower motor the blower is compressing air and the engine is pulling a Vacuum at the same time. The compressor (blower) creates a positive pressure over what the engine can create causing boost. The intercooler isn't so much as a restriction in a case like that but the cool dence air and the ability to withsatnd more boost without detonation more than makes up for any restriction the intercooler brings to the party.

On a N/A set-up you only have the intake pulses to pull through the intercooler. The air has to "find" it's way through the intercooler and some gets "lost" in the sharp turns and thin passages. The reason for porting a head is to smooth the transition of air flow into the cylinder. The smoother the flow the better the more air the cylinder is able to pull in. Everything from port shape to the back cut of a valve affects air flow.

Even if you made all U curves through an intercooler you couldn't cool the air cooler than the ambient outside air temp (not heat index) and the cooler would still be a restriction.

Youre on your own now, lol
