Anyone notice anything wrong with this motor?

I dunno if it's just me, but I think theres something wrong here.

[gtopaul]

it's hard to tell for sure.

I'd have to agree with Paul but... How do you pipe both inlets up?

If its something else throw me a hint...

[SharkmanBMW]

I agree, what's up with that?!
can you have both? or are we seeing things?!

[Kalevera]

Jon, you HAVE been busy :D

The supercharger feeds the turbocharger. So, from idle until whatever RPM, the supercharger feeds the motor the compressed air. Once at a certain RPM the electromagnetic clutch disengages and the turbo alone picks up from there. The car is apparently making 2.0 BAR boost with an unreleased amount of horsepower. I watched some videos of it though, and the boost builds RAPIDLY fast. Unlike a car with a single big turbo, the boost is there almost immediately.

damn thats sweet!

i've seen that done on a marine engine on a friend of mine's boat, never seen it on a street engine before, maybe its strictly for drag racing? the s/c forces air into what is called an aftercoler (same as an intercooler), it then sents compressed air to the inlet side of thecompressor on the turbocharger which goes to an intercooler and then fed to the engine and yeah it produces a huge amount of power, on the marine engine its something like 3000hp per engine and he has two in the boat

There is no aftercooler in this setup, it goes straight from supercharger to the inlet of the turbo, to an intercooler, then to the motor.

3000hp and there are 2???!!!
holy crap!
how big is the boat?!

[winfred]

probably a big diesel in a tug, the old 2 stroke diesels are prime for that, they allready have a blower just add a couple turbos

Two jet engines for a cruising speed of 60kts -- in a 118' yacht!

nothing wrong, a whole lot of right...

[mattyb]

a stealth yacht?

[emw525E34]

Now it needs some serious multiple stage boost controller!. Fueling would be a great challenge but some guy probably cracked that problem to a certain extent.

Why not?. I say, small turbo to get the low-end and SC for the high-end. This is no different functionally from dual stage twin turbos. Make it work is another thing altogether!!. The transition is a very complex thing to achieve in reality.

[Jay 535i]

When a supercharger and turbocharger are used together, doesn't it usually go the other way, with the supercharger producing boost from the drive belt at low RPM and the turbocharger taking over when the exhaust pressure builds?

[winfred]

that's what i was going to say, a small conventional turbo with a **** load of bottom end will overspeed at high rpm where the blower may be running out of capacity. another way of doing it is a 50-75 hp shot of no2 to spool up a big turbo off the line but that only really works on a drag car

[bahnstormer]

why does that look like an M30 oil filter housing?

[stx133]

Fueling would be easy, tuning the beast would be the entertaining bit. this would have some 'functionality' differences to twin turbos, the ramp up to boost would be much better, depending on the control system there could be 'turbo lag' basically eliminated from cruise and efficencies would be better without running an inefficent small turbo when on full boost which would generate a lot of heat. the intercooler would take most of it out but you dont need to create more work for yourself.

The transition point could be set up with two pressure sensors feeding back to the control module, one after the charger one after the turbo. when the pressures are equal, switch off the cahrger and let the turbo do the work. there would have to be a draw through bypass on the charger for the turbo,
i have seen similar setups on a 4AGZE corolla motor, the charger doen not pipe into the turbo, they have seperate intakes and a joined discharge into the cooler.

looks like an E34 M5 lump. same or similar blocks aren't they?

[SRR2]

15 gal per nautical mile. OOOOOOO-K. I'm sorry, even if you're Bill Gates, you don't need a planet-wrecker like this.

[Jon K]

Its not, its an S50 oil filter housing, probably because it's an S50 ;)

[bjl4776]

Its an S54. How can you boost that much on an S54, the CR on those are already like 11:1 or something like that. The valves on those engines would float with any extra pressure, those springs are so small. I guess if the guy has enough money to hypercharge it then he had enough money to rebuild it.

I'm not Bill Gates, but I need it. :)

The new 5 series diesel has two chargers (from what I understsand)

one to help reduce turbo lag in low rps, and the other for when the rpms are higher!

(it was on an episode of top gear this season)

The old RX-7 had that too. Called 'sequential turbocharging'.

[niall]

from the oil filler cap location, its a S50,
in case anyones interested

[SRR2]

Gee, I wonder why anyone would need a STEALTH high speed boat. Hmmmmm.... Let me think....

[winfred]

euro maybe, our s50/52 is not double vanos it looks like a 325/525 motor

For the only profession that could pay for such a thing. :)

[bjl4776]

Yea, but look at the valve cover. The euro S50 B32 that had double vanos looked similar to our S52 not the S54, unless somebody changed the head with an S54 head.

Dunno what to tell ya, its a car from South Africa with a Euro S50 B32

damn, i swore that the euro S50 B32 looked different than that, oh well...

[Uber Soldat]

The guy that put that Turbo and supercharger onto that engine tuned my car.
His name is Sav. Last i heard he got the car running quite well.

I doubt he tuned your car. But ok.

[Uber Soldat]

No i mean he cut the cams, chipped and dyno'd my car. If you want proof i can scan the dyno sheet
