GT-4 hood vent, why is it where it is ?? Options

[popstar]

the vent in the hood of a GT-4..... sorry i don't see how it works in the posititon it's in ????????????

as the intercooler top box sits between the vent and windscreen !

i have a plastic rain trap to catch any water, thus stopping any flow of air
plus i've got 1" of insulation to the underside of the hood !!!!!

if it's ment to help cool the top box of the intercooling system, them surely there need to be a through flow of fresh air via that grill and out of the rear hood slots !!

anyone ???

anyone understand what i've said ?????

the vent sits right over the HOT exhuast manild and turbo to vent all the hot air produced by the manifold/trubo (ever see pics of exhaust manilfolds glowing? thats a lot of heat) .

you shouldnt have any hood insulation covering the vent. if u do, then its probably something a former owner could have done. i would recomend cutting out the hole so the vent can do its job. rain, or snow will not harm anything.

the stock intercooler is water to air, meaning that its filled with engine coolant, that is connected to a pump, that then goes to a small radiator that is mounted to the front of the car. if you are getting any heat soak in traffic, i would recomend adding in an intercooler sprayer on the heatexchanger, or maybe a small fan.

what do you mean when u say your are getting over heating problems in traffic? does the motor just seem slower because of heatsoak, or does the temp gauge in the car go up ?

edit: also, you should doubble check that the intercooler pump that sends cooant from the topmount to the heat exchanger is working correctly and that your intercooler is filled with the correct amount of coolan.

Actually, I'm pretty sure some stock gt-four bonnets (or hoods) did come with insulation, which does cover the vent.
