We have an Engine with a Twin Turbo fed Supercharger

it makes some serious boost numbers

but nowhere near 103lbs

I think the guage goes up to 5 bar

Damn, 5 bar = 73.5psi.

Awesome [evil]

As mentioned above, I knew the newer fords have dual turbos, one feeding the other.  I guess the point of my reference to two turbos in series is that even with the 2 in series, I don't think it's possible to get more than 50-60psi (just guessing)

Now, maybe if the second turbo fed a third turbo. . .

Maybe it's Canadian 103?

What's the conversion factor? [cheeky]

A buddy of mine used to have an F-250 with a 7.3L Powerstroke in it.

He had an aftermarket turbo, aftermarket intake, aftermarket 5 inch exhaust from the turbo back (  :o ), ecu, planetary rear end, aftermarket transmission, propane injection (the equivalent of nitrous for a diesel), nitrous (step after the propane), and big injectors...

...the net result was ~750 hp and ~1,200 lb/ft of torque...  ...dyno proven.

I'd imagine this was essentially what that dude was going for with just a turbo.

Got a house you want pulled off its foundation?  ;)

Gale Banks has some pretty cool turbo diesel projects, but they're only at 38 psi or thereabouts. 103 had to have been some mistake.

They actually make turbos that build on each other's boost?  Most of the time on the duals it's quicker spooling unit to take on the low rpms and then a big boy to hit the power band where it counts.  Maybe I need to increase my diesel knowledge.  Still seems fishy.  I think we should go the Canadian Conversion route.....

No, they don't.

Take two normal turbos, and instead of both feeding the engine, one feeds the second.  Get busy with google, search "turbocharger pressure ratio" and get to learnin!

It's called running them in series.  It's the only way to get crazy boost pressure AND still be efficient.  Note nonefficient = output temps of the charge is very high.  If you try to make 50 psi with one turbo your going to have air so hot you'll never cool it enough to be useful.  Detonation will be a giant problem.

ive built a few diesels.

Strongest running was a friends 5.9 cummins. Garrett ceramic ball bearing water cooled turbo. fed by a holset. It was around the 1100 foot pound mark.

103 lbs isnt unheard of. It is in the world of street trucks and stock blocks.

Just look at what the tractor pull diesels make. Its some serious boost.

Anywhere over 50 lbs on a stock ford block is asking for trouble. Ford sucks anyway.

Well, I have seen more than a few ford blocks split down the middle ;D

I think the guage goes up to 5 bar

5 bar = (about) 72 psi.  How much boost did it actually make?

103.. just boggling and well dumb.

And wow, that's one hell of a thrashing on that engine.  I'm impressed.

With enough boost and fuel diesel go really fast ;D
