Turbo Fed Supercharger!!!!

daver · 26-10-2004, 16:08

The following link is to a video clip of a rather neat turbocharged AND supercharger setup on an MX5.......would think that this is probably on the loopier side of insane! Click on coldfusion wmv. Can this be done on a 1.8 T

A bit like the old lancia s4.

It's different to the S4 set-up.... IIRC the S4 used a SC for boost at lower engine speeds where a SC is more efficient and then at higher engine speeds when the turbo was spooled up sufficiently a diverter swapped over to the turbo...

how much room is there in the octavia engine bay round the back???

whats the chances of a twin turbo?

also trying to work o0ut how the manifold would work? would it be like a 4-2-1 but with a turbo after the '2' section then a collector to bring the two together?

Lummox · 26-10-2004, 22:23

Didnt the Lancia S4 use a blow through supercharger?

A low pressure supercharger which blew into a turbo to get it going which in turn blew into the engine.

Yanks have started doing it on alot of Civics etc for street racing.

Lummox · 26-10-2004, 22:25

And twin turbo would be very difficult, not alot of room for one...lol.

Also RHD makes it bleeding difficult with regards to bigger/multiple turbos etc as the rack, servo and master cylinders get in the way, euro LHD cars are much easier.

Now iirc the S4 engine, displaced 1759 cc and is based on proven Abarth hardware and mounted longitudinally behind the front seats. In the 'production' cars its KKK turbocharger and Abarth Volumex supercharger boost output to a maximum of 250 bhp at 6750rpm and 2141bft of torque. That sounds a lot from less than 1.8 litres, but the similar-sized motor of the Lancia-Martini rally cars was persuaded to yield a reliable 470 bhp at 8000 revs, plus more than 333 Ib ft of torque.

The aim of using both a turbo unit and supercharging was to overcome the lazy low-speed response of the turbo. The supercharger looks after the provision of extra punch below about 3500 revs, and the turbocharger supplies an increasing amount of boost at higher rpm.

The competition S4 used exactly the same twin intercooler principles, but the transition from supercharging to turbocharging took place at higher engine speeds, between 5000 and 6000 revs. Developing the engine's mechanically driven supercharger and the exhaust-impelled turbo to the point where power and torque delivery were harmonious was a complex challenge. Fiat-Lancia-Abarth engineers eventually met it successfully, but as yet nobody else has repeated the experiment...

would the standard transmision cope with that amount of torque?

boyced · 26-10-2004, 23:10

same setup as the Nissan Micra March superturbo?

bengie · 27-10-2004, 11:56

thats mental, a 1 litre super turbo micra, wheel spin anyone??

i really should get back to work now

Nigel26 · 27-10-2004, 12:46

but its still a nissan micra !

the mx5 on the other hand would be cool...

I you wer a hair dresser with this you would blow all your hair off with the shear power....my bro has a supercharged mx5 that is pushing out around 180bhp, in a car that weights about as much as a mini! ( the old mini not the phat BMW one).....IT WILL EAT YOUR OCTY vRS FOR BREAKFAST!

doubt it

daver · 28-10-2004, 09:31

I think that you will find that BHP vs weight is pretty relative, besides i know for a fact that the SC blown MX5 will eat a standard vRS as that's what I have got by the time you catch it you are well into lost license territory.
