theory of a short ram intake

See alot of gtp owners running short ram intakes claiming cold air doesn't matter with a supercharger. How viable is that? Wuld be the easier route to just buy a cheap short ram .. I don't see the perks of the short ram but maybe some of u guys have more knowledge on this. Cold Air is better imo.but if the sc is hot. It Shuld still make some differences

Ever heard of an intercooler? Cold air is better.

Edit to add, I was thinking about ditching my fog lights and ducting cold air up to the fender to aid a fender well intake. The colder air you start with the colder air you end up with.

A lot of GP owners (or any car for that matter) are idiots and don't understand what is going on under their hood, they just think "ohhh look at this intake, my car is so fast now"

The colder the air is, the more dense it is, therefore the more fuel is required to have the correct A/F ratio. More fuel (at the right A/F ratio) equals more power. We can go deeper then that if needed but that's the basic easy way to explain it.

A supercharger only compresses whatever air is there, it is still read by the sensors and fuel is metered based on those readings, temperature being one of them. Simple expirement, drive your car during the winter and then during summer, even though there is a big difference in time, the difference in power will be definitely noticeable. Another way to show is go play around on a hot summer day and see how doggy the engine feels, then drive around that night when it cools off, dramatic difference there as well.

They drive grand prix, what do you expect? Haha

The real reason they run the rice pipes is a combination of cost and availability of space. Our cars have a sweet sweet hole right where we want it. A w body engine bay is not as nice of a place.

Also, most dyno runs are done with the hood open, and a big fan blowing at it. They don't really account for heatsoak with a closed hood.

Grand Prix guys usually cheap out just so they can hear the whine. You will want to duct the intake somewhere where it will receive air as close to ambient as possible.

Lol they also make intakes out of PVC pipe.. Honestly i dont feel much of a difference in the power if any one way or the other.. maybe a little from a stop but once you are moving the air under the hood is moving as well, thats why i have not put the lower half back on mine after the GenV blower swap.

I have a 2 piece setup on mine:

Connected together: Fender Intake

Disconnected: Short Ram

If inter-coolers don't work per the GP bunch, then why do aircraft manufacturers, heavy duty truck manufacturers, racing teams and the U.S. military use them? (I know, I'm beating a "dead horse", but just something to ask the GP guys should they question why use an inter-cooler".) - BC

Intercoolers do work, i think the thing they are saying is the Short Stack (SSIC) dont help much.. they say they heat soak to fast and cant keep cool like the full size ones. Turbo intercoolers are also very benificial on turbo/centri chargers. Intercooled cars dont need a Cold air/Fenderwell intake because the IC will cool temps to ambient air temps anyhow.

Not necessarily, mass air flow may exceed the intercoolers capabilities. Keeping the whole air induction temperatures down from intake to inlet valve helps make maximum power.
