Check out this turbo setup!!

parallel compounds???

 

[JoshH]

That's really odd looking and hard to follow, but it does look like it might be a parallel compound setup.

Quad turbos on a six cyl. that's impressive.

Ya, id say thats parallel compounds, just bridged in as couple of places but at the same compressor/exhaust stages. pretty cool pic! Where'd ya find that? Truck? Tractor?

 

[Bluemax]

Is it just me or does the exhaust bridge between the second turbo's after the first two? If so is there a special reason you'd want to do that?

Appears so! My only reasonable thought would be to keep drive psi's equalized between them? Keep both turbos running at the same speed to keep one from working harder than the other? If one did work harder I could see it overspeeding one set and trying to stall the other and also beat the air up? Experts, whats the reason?

mmm capatilar

DANG was that a monster truck???

Dual compounds.

Dual compounds.

GOOD GOD MAN! Now you cant go postin up a pic like that and no info! (1st pic too mike!)

Lemme guess, Alky super stock? What kinda boost, HP/TQ, spark plug convo? Etc...

 

[JOHNBOY]

Yes that is a booze fed super stock. Jordan Lustik's Silver bullet reloaded. I have no Idea what the boost is on that ride. But I bet it is high.


Distributor on this forum is a lead wrench on a more turbo pulling tractor. IIRC 500 cubes , sigma pump and 200+ psi of boost!:rockon::rockon::rockon:

the pic I posted is of a pulling tractor, I dont know how it works and thats why I posted it.

If they are running 3 cylinders off one charger, the exhaust pulses might be too far apart to make full boost. So by running a bridge, you cover the "gap" between pulses better?
