supercharger + turbo = ? pros and cons?

[LegoHead]

Would it be worth it?

I am thinking it will eliminate the lag and produce big power.

Anyone done this before? Doesnt have to be a clio, just interested to see if its worth it.

 

[jesus]

Superturbocharged? Are you pissed?

 

[DrR]

VW 1.4, they already sell them in the golf.

 

[LegoHead]

serious question, it wouldnt be too hard to bolt all the bits onto the engine. Turbo is already there and GDI have all the bits for the charger.

I would lose the aircon for definite.

 

[Jamie86]

Delta S4 as well seemed to be ok with it

It can and has been done. called compound charging.

IMO, just use a supercharger and spec it right

But that would just be another supercharged clio. If I go supercharged the turbo will be staying too.

Depends if you do it to a bespoke build spec or not. Nothing BIG power out there yet

 

[Ash - Clio GTT]

would have to make sure you have forged internals to make the most of it, then huge turbo that comes in later in the rev range, smaller supercharger to get the boost early in the rev range. Supercharger would have to have some sort of clutch to disengage once the turbo spools up then a potentialy complex intake system with some sort of actuator to change intake from the supercharger to the turbo at a given boost pressure or revs. Maybe this part could be adapted from the 1.4 vw engine?

Sounds like it would be expensive R&D and you would prob only get the same power as a well setup supercharged engine, something else in the engine design would become a limiting factor.

Oh and as for cons, no aircon on hot days

 

[stevo172-RWD]

how would you run both?

one through to the other?

eg..-air filter-turbocharger-supercharger-chargecooler/intercooler-inlet manifold?

why not go twin turbocharger instead?

all you need then is another turbo the same as you have.
a new exhaust manifold.
larger injectors?
poss a better cooling system?

oh and some better traction.

 

[LegoHead]

sounds like a ball ache then. I have read that it is easier to put SC and turbo in series than doing twin turbo. Might be easier just to mount another engine in the back.

 

[stevo172-RWD]

do it!

 

[ianeire]

Nissan used to twin-charge the K10 Micras.

 

[stevo172-RWD]

bigger turbo?

 

[LegoHead]

bigger turbo?

And put it where? It's ok for you with the engine in the wrong place but it's tight enough as it is for me. The turbo is nearly resting on the brake lines.lol.

Havent you got a Ktec turbo kit? And don't they supply a (cougholdcough) T25 or T28 journal bearing?

Surely if you really want less lag, get a PROPER turbo manifold made up and a ball-bearing GT series turbo. f**k-it, Go VNT if you really want a challenge.

 

[Hutchie]

alter the manifold to come round ontop of the gear box, like the 5 :rasp:

his was (IIRC) a BBtuning kit originally. Those kits look like a T25 to me.
The current K-tec kits all use a GT28R (2856)

Big power, I'd go for a tubular manifold an a GT2876R.......oh i've just made a mess

 

[Mark One]

OP -

Those kits look like a T25 to me

There's your problem

 

[172_Cup_Lew]

As mentioned above, twin turbo it, or go nuts and whack another engine in

shouldnt experience much lag with a small turbo, but two engines would be something special
