Remote Mounted Twin Turbos

[OrangeMustangGt]

Ok guys....i may be crazy, but i think i may have a good idea here
After Looking at/around/under my car i decided on what i think is the EASYest way to do

Proposed:
Twin T3's 60series.....with a small a/r...~40 or something.
Blow through MAF with 42lb inj's.

This idea will allow me not to even have to mess with my A/c, ps, smog, or even my headers. It will fit in where the exhaust normally goes. there wont be any excess heat in the engine bay, and it will appear stock. The long intake plumbing will get ~50% intercooler eff. so i most likely wont need to run one. The only down side that i see, is LAG, but i believe the small a/r will combat this. Tell me what you think.

I will run a scavenge oil pump, and i wont even have to tap my oil pan, i can dump it through the valve cover, etc.

anyhow, here is a ROUGH drawing on what i need. I have the money ready, and im just getting ides on pros/cons.

i don't really have much input to give you about your idea, but i had to give you props on your attempt to illustrate it. Nice job. one day it might even be hanging on a wall.

Hmmm.... how low would that crossover pipe be underneath the drive shaft? I don't know if it would driveable on any kind of bumpy road, and I've driven around Cape Cod plenty of times and I know how stellar those roads are.

I think you're theory is sound but its gonna take one helluva fab job and I dont know if you have enough clearance under the car, ESPECIALLY with the 2 inch drop you have.

Could you just not do the crossover there? You know..... run it on up somewhere that you wouldn't have to worry about it hitting the DS..... then do the crossover. Or would it have to run straight into the #2 turbo? It's definitely a different idea. Good luck.

There's a company producing systems like this. I just don't remember the name. But I think it was like $5k or something for a single turbo setup.

 

[SeventyMach1]

Yep....and I checked with them. They don't offer anything specific for our cars yet.... but they told me that as they get more popular they may produce a kit for us...

has something similar for other makes

 

[fiveohh94gt]

my thoughts exactly, after seeing some rear mounted turbos on an f-body, me and my dad have been trying to figure out how to engineer a very similar set up, we were actually just talking about it before i logged on here

 

[Mac-man]

what about if u ran a pipe along the drivers side of the car rather than a cross-over. and just had it curve around inside the bumper and come out the fender like a factory styke CAI, only have the two pipes meeet right under than fender area? just a though to help with clearance.

 

[OrangeMustangGt]

yeah, i was actually thinking maby instead of the cold side crossover, i would make the merge up under the tranny area, where i have room. Thanks for tehhe input guys

my issue is with the oiling. any back pressure on the oil return line and you gonna get a lot of smoke. and damage the turbo. thats one reason you don't see alot of low mounted turbos. they need there own oil pump to push the oil , to return it.
i'm not saying that it can't be done. just if the oil pump goes that turbo or turbos are done. they become a paper weight very quickly.
and those sts kits are mounted like that for a reason on the f bodys. ever seen the engine bay of an f body? you couldn't drop a screw driver and lose it in there. lol

recomended book- Maximum Boost, designing , testing, and installing, turbocharger systems. By Corky Bell

read all 230 pages and then tweak your design. trust me you'll look at it in a different way.
good luck

Donkey is dead on, the problem will be with the oiling. The INCON twin setup that was popular years ago used LOW mounted turbos which made it REALLY stealthy, but there was always a problem of getting the oil to return to the motor. DO some searches on turbomustangs.com and you'll find a lot more info on this. I think the pumps that INCON used were known to fail, were very expensive, and are nearly impossible to find now. If the pump fails... bye-bye turbos.

 

[Zero Signal]

I wouldn't. You need those things to get as hot as possible. Also, the longer the plumbing, the more hydrualic losses. With plumbing like that you will definitely see a problem.

 

[94_302]

This may sound like a dumb question but what happens if you are driving around and get stuck in the rain. Is there anything from preventing a large puddle of water splashing up at the turbo's?

Build it, and learn.. I don't believe I've seen one done this way yet, so why not be the first to see how it actually works. then give feedback and post pictures.

hey mike (offtopic) but can you give us an update on your car if there is anything to update

Besides the oiling issues, the miles of charge piping are not going to do you any favors. You are going to loose pressure and velocity. I would imagine the boost leaks would be a common occurrence beyond what is normal just from debris in the road. The other issue you might have is boost control. The only way to do it would be running an external gate and changing springs. Adjustability would be difficult since regular vacuum hose could collapse if it had to be 15 feet long. A vacuum block would be the best bet. Heating up the fuel tank would also be a factor to consider.

I can't remember where I saw it, but I saw a picture from underneath a 99-04 stang and they had 2 turbos mounted right after a set of longtubes. I don't know anything else about it, but it obviously worked. Maybe you don't have to mount them quite as far back by mounting them after a set of longtubes. I don't think they would contribute much more to engine compartment heat. Although, I think they would need some heat shields to keep heat off the floor board. I dunno, just my .02

 

[OrangeMustangGt]

ok guys, whell as far as the oiling issue, i dont think it will be. I will get an electric scavenge oil pump, and will monitor it with a oil pressure guage. As far as the intake piping, it wont be any longer than a normal car if it had an intercooler, so thats a non-issue. I realize turbos use the heat+pressure to operate, that is why ill be using a smaller a/r ratio. Also, if i need to, i will wrap the pipes back.

You need to remember, where i will mount them, in front of the rear axle, physically isnt that far away, its about 5' from the headers..... anyhow thanks

I think you will need to run a pretty small diameter duct up to the intake. If you run it too big, you will have problems building boost. The TT will definately help compared to a single turbo though. I have a complete turbo set-up that we built for a Focus sitting in my garage. We set it up in the downpipe just after the header, and have a big FMIC, and all that good stuff. I had most of the ducting bent at an exhaust shop. The problem is, you have to mock it up before you find out where you need bends. I did that with a variety of rubber elbows (45*, 90*, ect.), clamps, and pieces of pipe. Pieced it together, then had a pipe bent to that shape. It took a while, but it turned out pretty good. After we got it all done, my buddy decided he didn't really have the balls to put 10PSI to his 2.0 Zetec after all, so now it all sits in a box in my garage, all the way down to the boost/oil pressure guages, and fuel injectors . Good luck. It should be fun.
