: Does a radiator have to be mounted level?

Simple question, complex reason.

Does a radiator have to me mounted level (as in | ) or could I get away with tilting it forward ( like \ )

Reason being, I'm 100% out of room with the manifold I have and the wastegate mounted on it. I don't want to go half rad and I'd like to keep the mizu radiator I have. I'd basically be cutting a radiator sized notch into the radiator support to get the extra half inch or so, and then moving the radiator brackets towards the front of the car more. Woudn't be any extreme angle, just enough so that the wastegate is comfortably away from the fan shroud. A 1" movement at most.

Well the whole point of the radiator is to have air pass through it. I think you'll find that if it's mounted at an angle your fans will probably come on more often, but it may still function absolutely fine.

Get rid of the fan shroud. That should give you the near 1" of play that you need.


Mounting the fans directly against the radiator is perfectly fine, and if anything allows more air to pass through the radiator and into the bay area vs having the shroud. Also gives you more room to move the fans left/right depending on where your wastegate is.

Lol.

I know that Corvettes use a (very) slanted radiator. Assuming Chevy doesn't have crazy radiator technology, I think it's safe to assume that any radiator can be mounted like that. Fallacy has a good point, though, but at the degree to which you're slanting your radiator, I doubt you'll find much difference in air flow or fan runtime.

if your not keeping the ac ( most turbo guys dont ) then you can get a set of fans the can be set up to push air ( not pull ) and mount them on the front of the rad . theres your extra clearance there ..

Corvettes still use rear leaf springs for christ sakes..:tounge:The car as a whole is old technology.Sorry for the off topic response.:oops:

Hmm, food for thought. I'm still not sold on cutting into the upper radiator support, and tilting the radiator though.

My other option is to sell the current manifold I have, which is already up in the for sale section, and go with the newer lovefab EQ that has the wastegate on the side. I'm strongly leaning towards that at this point. I mean, I'm already in pretty deep, whats another $300 into the money pit.

If anyone has interest in a used lovefab EQ for cheap, cutting their rad support, or going half rad status, it'll be there.

Sell yours and buy a tucked one:)

Now that would be the baller thing to do... unfortunately that's a project I have 0 time for.

To have a full size radiator in my civic with my H swap I would need a tucked one because my alternator sticks out to far

the older nissan z's had a pretty slanted radiator as well... with a bit of creativity you should be able to get it mounted a bit forward.

Pretty sure FD rx-7s have a slanted radiator as well. At least the setup I've seen it for a few turbo FDs I've seen

corvetts do not use rear leaf springs .. they use a cross spring to take the place of coils front and rear not just rear .. btw check the lap times of a z06 compared to any exotic and then tell me there old technology .. the z06 is one of the baddest cars on the planet and for a 3rd what most exotics cost .. the slanted radiator works fine because its ducted to do so amd as long as the cap is at the highest point you could lay a radiator at just about any angle and it will work fine as long as air goes across it ..

Air needs to go through a radiator, not across it ...

I think that is what he meant, which is why he bought up ducting.

If the radiator slants, it has to have diversion plates on the sides and top so the air gets forced into the radiator and can't sneak around it.

i bet with some creative fabrication you could lower the radiatior mounts enough to move it directly forward, underneath or even in front of the radiator support. like drop it down about 2 inches and then forwards an inch or more. however, wings idea of removing out cutting away a bit of the fan shroud is probably the easiest and most cost effective solution.

Get under a new corvette and tell me what u see.They do in fact use rear leaf springs. Anyone can put a big motor in a fiberglass car and make it fast. Have you ever been in one? Im guessing no since the inside is full of cheap silver/black plastic panels and covers that get scratched easily and peel off.Part of the reason why their so cheap. Insides look like a cobalt, besides the head up display, the vette is pretty cheaply made. Again,sorry for the off topic response fellas..

Something else to add that for whatever reason psud3ity didn't mention (shame on you man!) For those that don't already know, Ontop of the large Mizu radiator - he's using a mizu cooling shroud and (2) Mizu slimfans. That's the shroud I was referring to since it's already a separate piece that would give around 1" of clearance if mounting the fans flush vs using the shroud.

I've decided that rather than mess with the radiator I'm going to get a newer manifold with the wastegate out the side.

Equal length also a bonus.

That said, the mizu fans aren't much larger than the stock fans... it's the radiator core itself that's larger. The fans are actually "slimmer" than the factory ones.

That's why I suggested doing away with the shroud for the possible 1" of play - but you would have to measure to confirm exactly how much room that would give you. Maybe it would work, maybe not - was just a suggestion. :silly:

do away with the shroud, move the fans to the front of the condenser.

z31 radiators are almost vertical.

Just for a point of thought, the rally and drift teams that use god v-mount setups, use a rad with a 45 degree angle on the fins, to get proper airflow.

If you set up your v mount properly, the air will be forced through the intercooler and radiator just fine. Angled fins is just showing off.
