intercooler fan shroud??!!

[gtfrede]

My newly aquired 87 t has a shroud on the rear of the stock intercooler that uses the factory fan on the end of the crank to help pull air through the intercooler at low speeds....my first thought was that this may pose a restriction at higher speeds where the front shroud would be more benificial without any kind of restriction at the rear of the intercooler but I keep bouncing back and forth as to if I should keep this piece on here....is it rare and can anyone shine some light on this? I have done all the research possible on this piece and the best I could find was that atr made one and one persons opinion that it was crap and to remove it.....car is a street car and will prolly never see quicker than an 11.50 on e85....

Thanks for all input! I need opinions!

kenne bell had a fiberglass shroud and ATR had an aluminum boxing kit

theres no harm in them as long as they arent hitting the fan blade and they can help on cool down ,

ive also heard some say the crank fan is useless too, if they bothered to monitor inlet temps after the intercooler they would have to concede that it is important . the colder the air the more air goes into the motor ,more air means you can add mor fuel and more fuel will yield more HP


think of this your burnout and susequent spoolup sends enormous heat through the stock IC , the whole time the car isnt really moving and without the fan theres no air moving acress the core , then when you launch and boost skyrockets temps into the IC go way up but still no air is moving because you still arent really moving .... not to mention the fan cools the IC after a blast while your sitting still with the motor running ....the fan is important on the stock location IC

now those Kenne bell and ATR filter canisters (AKA ram air kits) while they did provide cooler air and work fine on the street they also restricted air greater than the cooling benifit at track speeds and even stock you will run faster at the track without those canisters

See it sounds like a very well thought out piece...I was just skeptical as to how efficient it actually was at speed...say above 65 70....also thought it was funny I never heard about it before...I believe it is a extremely well home built jobber or the kenne bell unit because it is black and doesn't appear to be aluminum

Appreciate the input pacecar...you reaffirmed my choice!
