Adding an aux. fan to an intercooler???

Ok, I was sitting at work today and saw a little 10in flexalite aux. fan, and that got me thinking that when I put my intercooler in the front airdam of my charger, Would adding a aux. fan make more power?? The way I see it is more air= more power. Any thoghts??

i would 't waste the money on that... i might be wrong....but the only time i guess it would do u any good is when u are at a stop... because if u are running down the road the air movement would force more air thru than a fan....i would go this route http://www.designengineering.com/cry...r_sprayer.html


i plan on making one myself... not sure how to do the fuel line coller?

It'll work, just like the fan on your rad.

[FrankNbeans]

it will work.. but will it give u more power.. i doubt it... we talked about the CO2 cooler on the board b4.. and it was brought u p that the only time it will benifit u is when u are running your car hard for a long amount of time... so i am just guessing that the fan will only do the same... but with the CO2 cooler... it makes the are much colder than the fan...

Works great for me? Cools down the intercooler after a hard run at the track while waiting in line for next run. You never have to refill it. If you have poor air flow into the front end like my 92 Daytona it might be worthwhile to you. Another problem I have is with my stock air box sitting over my turbo sucking in hot air heating up my intercooler untill I get moving. The fan really helps me!

did u actually "fell" a diffrence by adding a fan..??? wonder if anyone can do a dyno test on this

I can see the fan being usefull just like the cooling fan on your radiator. At idle, while no air is moving over the cooler, then fan draws air through the IC and cools the intake charge. Of corse you would not need it on after you get moving, but im sure it would help give you a denser air charge off the line and a couple extra horses too.

It will make you more consistant power #'s.

It will save your engine!

On a hot day, when you are not moving, the intercooler heats up to the temperature of the engine compartment. Lets say you're at a light or at the track and you take off hard. The intercooler is laready hot and won't have any effect until you finished the 1/4 mile.

Keeping air moving over the intercooler when you are standing still is important. I know!

I was wondering how much air actually flows through the intercooler cooling fins at 60 mph. I guess it depends on your front end design. I know my 92 Daytona never moved enough air. During the hot summer going down the interstate at 70 mph the car would run hot unless I ran the ac which in turn cut on the fan. With the fan running it would drop temp from 3/4 of guage to 1/4 in a matter of minutes making me believe that the fan moves more air. I am not able to mount my intercooler in a opening where all of the intercooler is exposed to incoming air due to the design of the front of the car. Anybody know how to figure how much air, measured in cfm ( like electric fans are rated ) , moves at a certain mph?

[WLKIVETT]

It's a simple calc.

Just convert mph of air thru the cooler to feet/min then multiply by the free area of the cooler in feet squared.

Taken a step futher if you measure the temp change of the cooling air as it crosses the core you can determine the amount of heat removed by the cooler.

heat rejected=CFM(1.08)(temp change)

Hey DRSracing. You related to DRS from slot car DRS?

I have a 944 cooler in the nose of my S.C. It sits about 4" in front of the radiator. I used an auxillury fan to pull air through the intercooler and push throught the radiator. Intake air temp @ operating temp without fan 130-140 deg, with fan 130- 140 deg. I noticed no difference in any driving conditions. Although i could see were there may be more benifits if your intercooler is located underhood.
