turbo/super charge

is it possible to super charge and turbo charge one engine?

no....

Well that was easy enough......

YES.

I'd like you to name an engine that can't be modified for turbocharging and supercharging.

That's right, you can't.

Here is an example of a supercharged and turbocharged Skyline engine:

Ohhhh. The power! The POWEERR!

I think that is insanely useless.

only if you freak ...and you love your car ... otherwise , for same money you can have another supercharged car ... not every engine is built for such great powers ...if the engine block of the same mark is used for cars with turbo , so there shouldnt be a problem..(for ex.BMW)

A supercharger would make a handy way to get a large single turbo to spool faster, IMO.

i hope the driver who will test the enigine gets blown up.they are gonna need a niffty billet carnk to keep that thing from overeving

That engine is crazy!

Ofcourse it is possible, that is what alot of rally teams did on their Group-B cars.

basically people do this to minimize the turbo lag, nowadays superchargers comes with a electronic clutch thing, the pulley of the supercharger can be dis-engage by electronic components. As you all know that turbine need to receive exhaust gas to spool up to a functional or optimal state. this is where the supercharger do the air compression during turbo lag. when it reaches enough exhaust gas to spool the turbine, the supercharger will dis-engage and let the turbo take over.

Its a great idea thoerytically, but i dunno how well this sort of system works practically.

*supercharger driven by crank pulley, almost instant effectiveness but with lower efficientcy (less than 70%) due to massive mechanical components (pulleys, belt, the supercharger itself)

*turbocharger running alot higher efficientcy (up to 90% or more), you will get more boost easily than superchargers, cons are turbo lag, maintainence (example: turbine lubrican fluid, refurbish turbine), heat dissipate (the turbine may run more than 100K rpm, and the exhaust gas from the combustion chamber of highly compressed air).

Each part can be a complement to the other.
Supercharger for low end torque and turbocharger for high end power.

There was a car produced that was turbo and supercharged. I forgot what the name was.

lol this thing is crazy.the most craziedt thinbg ive seen was a supercharger CRX that looked like a funny car but was a a pretty much stock body and chassis.some of yalkl may know what ime talkin about.

How are these mounted according to the intake on the engine?
It sounds like an interresting technique anybody got a diagram over the intake, intercooler, turbo and superchargers that shows how they are mounted? the pic of that Supercharged turbo RB26DETT is a bit hard to make out.

boganbusman · Post by **boganbusman** » 19 Jan 2005, 12:59

How can you not get it? the pic is quite clear IMO.

Turbocharger/supercharger ~~> intercooler ~~> inlet manifold ~~> engine

Simple.

Sweeper · Post by **Sweeper** » 19 Jan 2005, 13:41

So there is nothing else between it? It is controlled electronically all the way?
I was unsure, it looked like it was mounted like that but I was a bit unsure as I couldn't see the whole intake manifold and all the pipes.

Thanks anyways boganbusman for clearifying that, helped a lot

I would love to have a closer look at the electronics used to control it though (funny sideeffect from being an electronics engineer.)

boganbusman · Post by **boganbusman** » 19 Jan 2005, 13:43

If there were any electronics, they would only be used to engage/disengage the turbocharger/supercharger.

Sweeper · Post by **Sweeper** » 19 Jan 2005, 15:28

With a closer look I ment having a look at the circuit diagrams.
You quickly get used to the logic gates.

MarlboroMan · Post by **MarlboroMan** » 22 Jan 2005, 18:36

well if you really want a diagram about it look closely at the same picture, at the background behind the engine, theres are some of them.

if you really want it so bad here is a rough sketch by me.

the pictures with red pipe...
(left) - most probably when turbo lag, the valve on the supercharger is opened.
(right) - when turbo is fully function, seems like that the valve of the supercharger is closed.

Hmm... that's pretty interesting.

how much HP is that engine pumping out?

donaldgladden · Post by **donaldgladden** » 23 Jan 2005, 23:03

Lord knows how much that thing is pumpin out

Really? Then could you ask him for me please?
