WHY did mazda never run a wing mount intercooler
WHY did mazda never run a wing mount intercooler?
I don't get it boost pipes could be made minimal, less heat than a top mount by far and no air being stopped to the rad like a front mount
similar setup to a skyline or silvia oem\?
any info much appreciated as im thinking of this setup for my fairy basic spec s5 turbo vert

why didnt mazda put a piston engine in their cars?
i feel like you about to try to reinvent the wheel with this project if you were to pursue it. how "basic" is your car? basic enough for the factory top mount to do just fine? maybe a little less basic to need a FMIC? or crazy enough to need a nice V-mount?

lol my question isn't really about my current car just really why a top mount intercooler was used over a wing mount like Nissan were doing at the time? not a dig at mazda just a question im interested to no the answer mate
didn't expect a a response so quick form you American bois u up late or up early haha

In my opinion the Rx7 was made to compete with other sports cars of it's time..including Porsche and of course the Datsun240.(this is for FC)
The fact that they did something out of the ordinary by putting in a Wankel engine and a Top mount on their turbo engine speaks that they didn't want the car to be a clone of anything..but unique.

mazda probably wanted to minimize turbo lag,due to the natural lack of low end torque in a rotary, and since the exhaust had to be so restrictive for emissions purposes
if u look at all the rotary turbo setups, they all implemented features for that, twin scroll, top mounts,
and then sequential turbos on the fd, and even the fds intercooler is mounted in such a way that it have very short piping.

Probably because Mazda didn't mount the engine anywhere near the rear deck. While a wing-mounted intercooler works great in a Porsche 911/930, there would be too much plumbing on an RX-7
Either I am not very familiar with wings on those cars, or what we have here is a failure to communicate.

yah it is a bit odd. Mazda has always favored the top mount but its clear why.
nissan doesnt use them in the cars you mentioned solely for the fact they'd never fit. the RB series engines are rather tall for the engine bays they are in and so are the sr20's. you would be hard pressed to fit a TMIC on those motors just for spacing alone.
I suppose you could raise the hood line like 3 inches but that would look extremely strange.

The area behind the front of the front fender where the windshield washer reservoir resides is where a "wing mount" or in 'merican English a "sidemount" intercooler would be placed.
Not a bad location as you have the brake duct for cooling and it does not impede radiator airflow, though the core must be rather thick to maintain a reasonable size which will limit airflow through it..

top mount might not be the best place to put the IC, but as a package, with the radiator and oil cooler and stuff, the stock cooling (rad, ic, oil cooler) works quite well at stock power levels.

If they put a side mount intercooler (which is what we'd call it here in the states) something would have to be moved or reduced in size. The radiator would get smaller, or the fan/fan shroud, or the intake airbox (more restrictive intake). Or the radiator and A/C condensor, or maybe the oil cooler would get smaller. Or maybe you'd have a shitty battery.
They were lucky that the FC is the kind of car that could have a hood scoop from a styling perspective. If they were forced to do a side mount (because marketing guys didn't want a hood scoop) something would take a hit. Look at the FD: its intercooler is behind the other cooling modules, but the radiator is at an angle and the oil coolers are a lot smaller. I wonder where Mazda put the intercooler on the rotary 929 in Japan, which had a 13BT engine.
The stock intercooler on the FC is fine for stock power levels, and it does ok with a modest increase in boost. You can't really ask for more than that.

F**K THE SYSTEM!!
I believe it has the same rubber piece under the hood but I'm pretty sure there is no hood scoop.
CLick on this link and check out post #25 i think it was. It shows exactly(pictures) how the Luce cools the top mount intercooler via duct on front grill/bumper which feeds into hood and out of the typical s5/s5 rubber seal.
