An idea for tt...
 

so why have no manufacturers developed a tt setup that has top mounted turbos? is it a space issue or just a practicality issue? idk about anyone else, but i think a couple turbos sitting in plain sight would be badass. could a manufacturer possibly develop a reverse mounted manifold to add retorfit onto existing tt setups to put the turbos on top. i kno this is a somewhat common practice in the supra, skyline, and sr20 world

however like i said, i dont know if we would have IC piping issues with this setup.


something like this...

(only without a turbo the size of a beach ball.....)

:yum: I feel like this is much more of a show setup and you will loose some effenciancy? (lag, heat issues) Maybe a turbo guru can chime in though..

The closer the turbos are to the manifolds, the quicker the spool. A reverse set of manifolds would be ideal for a twin top mount setup, but then where do the downpipes go? It would be very difficult to fit 2.5" downpipes, let alone 3" downpipes if the turbos were mounted up top. My downpipe setup was horrible....a 3" band clamp had to be used due to space constraints, which led to an exhaust leak.

one we have no room, and two you want to keep the heat in the exhaust and turbos for efficiency. theres much more to it but thats a few points.

someone has done it, do a search. :) hahaha the guy who beat me to the post :P

Much easier on the Supra since one side is intake and one side is exhaust. You couldnt fit two huge turbos on top like in your pic if it was a v6 supra. that engine is an inline 6.

ya i kno 98intrigue did it. that came out great look. so i thought if 1 was good, then seeing 2 was better lol

Not to say it can't be done though...

:yum: :drool:

As others have mentioned, a top mount kit is form over function. You want to hang the turbos as close to the exhaust outlet as possible to get all of that energetic hot air through the turbine. Moving them up away from the exhaust outlets just creates extra piping and loss of energy, not to mention if you have ever seen a turbo's hotside glowing yellow on a dyno, you would realize you DO NOT want those sitting that close to other bits of engine that were not designed to be exposed to that kind of severe heat.

yea like the radiator!!!

the manifold wouldn't have to be changed theoratically.. save for maybe the bolt patter and angle that the turbo sits. by just flipping it 180 wouldnt that gain the desired effect without increasing exhaust distance??

TBH im a little surprised a company hasnt done this on a show car yet. i mean 2 snails up top would look completely BA

something like this would be perfect. spool time increase would be neglegable and IMO it would make everyone that looked under the hood happy in the pants...

You should try it op..

I don't think the engine bay has anywhere near this much room to position the turbos in this manner.

I'm not sure what to tell you other than you are over-simplifying the actual engineering challenge by about 10^7 percent, and again, to make a kit that would almost certainly perform no better or worse than a low mount twin kit.

Most companies building these kits are doing so to make money and not one-offs to make people "happy in the pants." That whole recession thing has changed a lot of shop's thinking.

deal!

now if only i had the funds... Now accepting donations!
