What is the abundant air temperature of compressed air.
Dose it change dramatically from five PSI to fifteen PSI.
Won't one hundred eighty degree air cool two hundred degree air?
Can ambient air temperature cool compressed air down to ambient without some form of chilling it.
Has any one ever put a thermometer in the intake of and intercooler to find out just how hot the air is under boost?
So does this mean you have heard the motor running?
All depends on the ambient air temperature, how much you compress that air, and how efficient your compressor is. If you live in Death Valley and are cramming three bar of boost into an engine using an old 6/71 blower, your intake manifold temps are going to be through the roof.Probably. The more you compress the air the hotter it will get. You're trying to smoosh three times as much air molecules into the same space, so they get pissy and wriggle around a lot more. It's like cramming four kids in the back of the car for a long roadtrip.Yeah, a bit. Maybe to 190 degrees...Yes, how much it does depends on the thermal efficiency of your cooling medium. The more thermally efficient your intercooler core is, the greater the flow restriction will be. There will always be a trade-off, if you want really hot air brought back to room temp, you are going to lose pressure due to the restrictive design of the cooler.Only way to test the thermal efficiency of a core is to measure before and after temps. A car magazine I used to read here called Zoom did this all the time, testing different factory and aftemarket cores for comparison articles.Basically you want a good flow of nice fresh ambient air over a big enough sized core that you'll get good cooling, but without affecting lag or reducing pressures too much. You're bound to lose up to a couple of PSI through an intercooler, but that's offset by being able to run much better timing.
Altho this one might get you in the ballpark faster http://www.turbofast.com.au/tfcalc.html
Here's more.I plan on using a Hobbs switch to activate the intercooler fan. That way I don't have a fan running all the time while I am just putting around. Only on boost. What say you I use for and activation PSI. Do I need a fan when the turbo is only boosting at say five PSI to nine PSI. Then when it gets over the nine PSI I have the fan come on. I have heard tell that most subi's boosting only eight to nine pounds don't even need and intercooler. But when you get over that you do need one.
