Externally Mounted Turbos / Hood exit exhaust Suggestion??? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Bisofication · 12-15-2016, 02:27 AM

Hey there,
Since we all know how compact the engine bay is in the BRZ/GT86/FR-S especially with a turbo/supercharger kit added to it. I was wondering why nobody has come-up with a turbo setup where the turbo itself is mounted in a way where you don't cramp up the engine bay. Or why not even a hood exit exhaust so you don't have to have a exhaust pipe that goes all the way to the back of the car? I know it's 100% illegal in most countries but honestly I've seen crazier swaps/mods but nothing like I mentioned and most of the people who own the 86 have another car as their daily.

The only thing I found is a video of an Arab guy having a hood exit exhaust and that's it. Here's the vid :

Here are some pictures I found online (examples):

It's my first thread so be nice ..

There is plenty of room.
One tiny rock away from a damaged turbo.
Some people value their hearing or breathing.
Some people don't want that much attention.
Some people actually want to be able to drive their car daily.
Some people don't want cut hoods.

I'd bet because 100% of the time, it looks stupid.

That BMW is a photoshopped image. The shadow on the turbocharger is going opposite of the shadows from the tree, I think.

Probably because

A) It isn't necessary, plenty of room in the engine bay
B) The bigger turbos can still fit in the engine bay
C) The engine bay is big enough for almost any turbo setups
D) Most engine setups couldn't make use of a giant turbo that couldn't fit in the engine bay, even then there is probably still room in the engine bay
E) The example you have still has room in the engine bay to route a proper exhaust. The turbo is in a common location even with its sizing
F) That noise.... open wastegate and exhaust, because racecar

There was that one turbo in the FI Kit thread that had one mounted near the rear axle. It was supposed to be cooler. It was incredibly inefficient though.

STS system, that brings about a whole other realm of turbo talk that should be avoided.

If someone were to sell a kit that could only dump from he hood they would be severely limiting their market. Not many people would deal with this because it's insanely loud.

I had a t4 67mm under the hood with no issues. Could have ran a 76 with the same cover profile just fine as well. Exhaust exited the lower passenger side of the front bumper. It was quite loud fyi
