been done a few times on modded cars... ask focusbird... im sure her focus was originally turboed and supercharged

With one superchager, and one Turbocharger HTH

Probably a few ways to do it, but I'd expect to see the supercharger outlet is connected to the Turbo inlet which is in turn the outlet is connected to the manifold - probably via an intercooler.


For 37mpg+...add 22" wheels and use 0.41:1 final drive gearing

Paul it makes an interesting read but I bet it was or is a mappers nightmare.

I think her car was supercharged and then that was removed and then turbo charged, dont think they ever existed at the same time.

OK, Turbo-->Supercharger--->Intercooler--->Manifold


Just need to add that little lot to a H6 engine and a quad bike chassis, then you have the perfect toy

looks an expensive cost extra Paul.....!!...........

A guy in insure has a supercharged and turbocharged Nissan Micra, Nissan made them in the early 90's!!!!!!

BOB.T

Nope, FB's car had both at the same time for deffo

TonyFlow

Ahaaa - the old Micra Superturbo!

Lancia Delta S4 was turbo / SC was it not?

Yeah thats it! Only a 1.0, but seems to go ok!!!

There's a guy on the ClubGTI forum who's built a space framed turbo'ed and supercharged Mk2 Golf.

This is the only pic I have of it!

Didn't Koenig Specials once produce a Ferrari Testerossa with twin turbo's and twin superchargers, putting out about 1000 bhp on full boost?

The Chief

Knew there would be some info on it

More likely that the supercharger and the turbocharger are connected in parallel, i.e; both blowing into a common plenum, that's how Lancia did it with the S4.
I would imagine if you connected them in series as you suggest, you would end up with the drawbacks of both overcoming any benefits.

Problems with parallel running is you must ensure that the supercharger doesn't start blowing air back out the turbo at low revs/low throttle or vica versa Various ways round this though (separate throttles etc. )

How about a supercharged, and turbocharged E36 M3 motor ?

One of the guys who works at Power engineering owns a mark 1 fiesta that has got a cvh in it that is both tubocharged and supercharged Last I heard he'd taken the engine out and was fitting it in the back

Stiver3

So, do they run at the same time, or does one cut in, then the other for example?

Could you use the superchargers quick response untill the turbo has made full boost, then cut the supercharger and just run the turbo?

Interesting reading guys. lol.

On the Lancia delta S4 Lancia got around this problem by fitting a viscous coupling to the supercharger so that when the turbo was at full boost the supercharger cut out. This stops sapping the power needed to drive the supercharger.

Mine was supercharged and turboed at the same time (with nitrous) for about a year, had problems with the turbo though, PE think it was struggling cos it was being restricted by the supercharger, which was proved when the supercharger was removed and I gained a bit more power and more torque

Chris Todd at Power Engineering (that did mine) owns a MkI Ford Fiesta Supersport that has a 1.9 engine (I think) and is supercharged/turboed/with gas. It's currently in bits while he transplants the engine into the back, which I think he's almost done but obviously there's tons of other work to be done to it. Cracking little car, did a 1/4 mile in 12.9 and it looks completely standard apart from the roll cage
