Getting ready to attach front bumper cover.
I'd like to try and NOT put any holes in it.

What will I need to do to get air to the radiator then? Is this possible?

I'd like to not have to worry about mud/rocks etc getting plugged up in a
screen. Also I think it looks better.


Thanks!

Well 4d, we don't run a bumper cover becouse we have a narrow pipe bumper , but we have the front of our radiator covered with roll plastic. The trick is that you have to have a big opening from the bottom and a VERY good fitting shroud. Also make sure that your fan is no more than 2/3 of the way in the shroud and a high flow water pump. I know that what you are wanting can be done becouse we race in Central Texas and we can get away with that most of the time. We have people asking us all the time" don't your car get hot with the front of your radiator covered up?" we tell them it's a lot better than having your radiator full of dirt becouse it sure won't cool then!
Good Luck to Ya!

we always cut ours out and put screen behind it becausde you never know when that thing will fall off mostly just cut out the grille opening and then use a hole saw thru the bumper this also helps to hold it in place just run a few zip ties thru the holes

well, you can run the screen behind the nose for insurance but he asked if it could be done with out cutting holes in the cover. Our plastic is actually behind our bumper so we don't have that problem much.

The factory thought 'bout this and put a rubber air dam below the radiator on all metric cars it helps redirect the air up thru the rad instead of going under the car.It should work,i always ran one(found em in my competition's gut pile from building cars!)

Crew 42 What size of fan, rad, restrictor, pulleys do you use. Anybody here use stewart pumps. I put one on and it didn't make a difference in my temps at all. I want to run a closed front next year, but I need to get it to run cooler. I know it can be done because about 10 people run theirs closed off

We run a 30% reduction crank pulley and the aluminum upper. They say that with the stewart pump you should not run any water restrictors. As far as the fan 17" steel fan. The key ingredient to the whole deal is a tight fan shroud and the placement of the fan in it. You have to make sure that all of the air that the fan can pull comes across the radiator. Good luck in your venture. One more thing I don't believe that it absolutely necessary to get the stage 2 water pump, but if you can then you might as well save the weight.
I forgot about the radiator, the BIGGEST aluminum radiator you can fit under the hood. Make sure the tubes are not clogged and that you can see through it. If it is full of mud or the fins are all bent up then there won't be enough air pass through. But if you have been running a shaker or louvers or what ever then you might as well buy a new one to start off with becouse your old one is full of mud and the fins are bent!
