S.A. MSP's Twin Turbo Build Thread

Twin turbo? twin engine would be sick. You could mount the other in the trunk and make an AWD car that still gets decent fuel economy, just turn one off. What about how the muffler turbo's that the V8 guys are running. You could avoid the trouble of mounting it under the hood just routing piping would suck.
 
I see alot of my thoughts I told you from the beginning resurfacing from other people. Sequential turbos; small to large, added meth/ water injection, tranny bulid. Once my megasquirt is finished you won't have to worry about that alt. issue, you can stay with the stock. you should change over to a race cell battery and relocate it to the trunk. that will at least open up the bay a tad for you to do some of the relocating things like windshield resevior. and you could put your meth tank there or in the trunk, I have a lot of ideas about meth/ water so if you're interested in having that, let me know. Also with MS you can control the meth/ water and you'd have launch control, when you hit that it would sound so bad sitting at the line just banging away.
 
now there's an idea... Supercharge AND turbo that s***! That could be done right? Probably easier too...

volks did a car for europe that had both.. it was on a 1.5 liter and gave out something like 250+ hp right out of the box
 
to save space, you can always just put a screen over the turbo inlets instead of having long piping and a fat filter. A lot of DSM & supra/rx7 guys do that, works fine.

No intercooler would work fine for a drag-only car, I saw a 9-second 'teg the other day like that. But for a daily driver as you said this would be, you gotta have an IC, and you'll need a BIG one. Will the IC piping need to be larger than the CS pipes i wonder?

a partial Meth/water-injection system might be a good idea too. It'll help cool the s*** down and will add a lot of safe power. your cpu could maybe handle that as well?

I really wanna see this happen.

My IC tubing is custom 2.5 inch tubing, i think it sould be big enough, the screens might work but will then be sucking in hot air from the bay, well actually, that gives me reason to get a CF hood with vents close to the front, i'm also thinking of the IC nitrous sprayer kits, that will keep it nice and cool too

that is called the STS turbo setup, doing the lines and tubing will suck, so would the rain, there isn't much room under car either, it pretty tight, and no i'm not mounting a motor in the trunk, it's a daily driver and i need my WOOFERS (alright)

as for the battary i have the Yellow top remember, i could probably fit two in the the trunk snuggly. And i know ur a mad scientist so i will def be seeking your oppinions on the build :-)
 
15-inch wide tires.
mount the turbos down low up front, one on either side to take advantage of the air ducts (custom pathway) and don't drive in the rain. Then could you possibly just put the IC between them... That would mean you have a total of like 3 inches of piping! lol. Also, i remember Supman made a very creative air duct that was just a hole through the turn signal of the front headlight assembly. He just carved out that entire light/bulb and everything there so it lead straight into the engine for his SRI. Good extra cooling there or direct airflow there too...

it's still gonna be my daily my good man, excellent ideas but i have to think for everyday kinda weather, 15 inch tires will be cool tho
 
subbin

I once mentioned this idea on here and got mega flamed for it lol

glad to see someone actually doing it...and youll be the first MSP with twin turbos lol, NICE

as for your piping running like the Injen CAI on both sides, thats the way I have my setup and it works great...you dont have to remove power steering, but be careful the piping doesnt push up against the belts there or else you wont have that power steering line anymore lol (worked on it hellof late and didnt realize that one until it was too late...damnit lol)....what I eventually did was put a new, longer line on it and ran it a little further to the side and then U-d it around the pipe...fits great

kinda hard to see what I mean here...

power steering is kinda valuable in my honest opinion...parking is an absolute b**** without it lol

good luck to ya man!

(Please ignore the massive amount of couplers on the intake pipe....thats a long story (yes it has a story lol))
 
thanks for the support man, all the piping will be completely custom fabricated to fit like and extremely small tight glove lol, but all bends will be well thought out, might not even need to extend the power steering line, for a daily i think the injen idea is the better option
 
no problem man

thats just an issue I came up with when I installed that double-injen setup (haha)...its kinda hard to avoid it cause if you try to have the piping higher to clear it, then the hood pushes it down anyways...but you could put a small bend in there to kinda route it away from it (like a 10 degree bend or something, just to kinda V it away a bit)

youll have to move the washer tank (like you said), but a suggestion...how much do you need the washer fluid? what I would do (that Im actually going to be doing soon) is to utilize the pumps on the tank to use as a squirter for your intercooler...theres a DIY howto on this forum somewhere

just a thought (thumb)

seen the sprayer and actually created one for myself, seperate of the washer resevior, it has it's own pump and resevior, but I haven't wired it into the car yet. I have had it ready for almost two years. lol
 
I made a little drawing way back, of a sequential setup that I have never seen done before. It's floating around one of these threads somewhere.

Basically, you run a large turbo in the msp's stock location, and a smaller turbo where the stock airbox sits. Exhaust manifold feeds the large turbo just like a normal single turbo setup. Connect the turbine outlet on the large turbo to the turbine inlet on the small, with a pressure actuated exhaust cutout in between them.

Compressor outlet on the large turbo goes to a FMIC and then up toward the TB. Compressor outlet on the small turbo runs straight up towards the TB and is Y-piped with the larger. A pressure actuated solenoid flapper valve will open and close the smaller turbo's side of the Y-pipe.

Downpipe from the small turbo is tied into the exhaust system. Intake for both depends on where you want your MAF.

Fairly easy setup, the hard part is timing everything right. If you get your exhaust cutout in between the turbos and the flapper valve in the Y-pipe timed right, you have a perfect sequential setup. Small turbo spools and goes right into the motor, indirectly spooling the larger turbo. Once your large turbo is spooling, the Y-pipe closes, cutting off the feed from the small turbo (and preventing any backwards pressure from going down the small turbo's compressor outlet pipe). At the same time, the exhaust cutout opens, letting the large turbo breathe freely with no restriction.

The only variable that I can't figure out without actually testing it, is whether or not the large turbo will create too much parasitic drag being in-line first. The smaller turbo might not spool quickly if the large turbine is slowing down the flow too much.

However you do it, have fun and post lots of pics!
 
at the autox this weekend was a VW Corrado that was twin charged (super/ turbo) sounded amazing


see the fun you miss running off to carolina every weekend Jacques

myust be the easiest twin setup possible..

the SC comes from the corrado and bolts on the head, and the turbo setup from a 1.8T which is basically the same motor and the manifold prolly bolts on as well..

must be a special thing to drive :)

That's exactly what i was imagining up in my dome.

--I too was thinking about an intercooler-sprayer made from the washer fluid tank & pump. Great minds think alike i guess...
