Default radiator mounting

Hi guys,

I finally got the replacement for my Godspeed radiator that had a crack. Is mounting the radiator titled for better air flow or for space saving? With the GS radiator tilted I don't have much clearance on the bottom where the AC lines are. I was thinking of mounting it vertically for more space.

Thanks,

t.t.

No reason to tilt it unless you are having trouble making it fit or you're routing your IC pipes over it.

Hey Pakman, what are you using as a hood prop? Did you mount a gas shock?

tilting a radiator is to aid downforce
in tilting the bottom back toward the rear of the car, directs the air up and creates downforce
if you was to tilt the top of the rad towards the rear of the car this would create lift wich isnt good for areodynamics

a radiator mounted vertical will be fine and will cause no problem

how do you figure this? i think you may have your thesis reversed, it appears to me that it would be the other way around...but what do i know, i never studied areodynamics

If you're treating the radiator as an airfoil you have issues. Air should flow through a radiator (or any other heat exchanger), not over it...

i didn't suggest to use it as a airofoil but from a design point of view this is how it would be viewed

the core of the radiator as air passes through will direct it according to what angle its at

so you are not familiar with the term 'opposite' are you?

tilting the radiator will not direct air, it will deflect air and you will loose some cooling (marginal)
i still believe that your train of thought is incorrect, i can see what you are thinking
think of it this way, aerodynamics of a car increase/decrease surface area in certain places to increase/decrease the speed of the air passing over/under these area which is waht creates downforce/uplift respectively...
a radiator or intercooler for instance, are not areas where air is supposed to pass over, thats why in most cases a radiator/IC are after the bumper cover, not in front of it...
makes sense?

That graphic is missing the HOOD preventing the air from ESCAPING, thereby negating any AERODYNAMIC BENEFIT.
