this would be interesting because i prme you could have alrge turbo being fed by a super charge for less lag?
would it work like that?

possibly im sure someone managed to do it?
also take a look at the nissan march superturbo

Thats what I am going to do
, I have a supercharger with an electromagnetic clutch in so I can make it knock off when the turbo makes some boost.I am planning to do it, just working some last bits out of how its all going to fit together!

Cheers but that thread is more about twin turbo setups and I want some info on supercharger and turbos working together on an EP.
i have the management for it, but don't want it yet.
have discused it with some corolla drivers who build it, but the different versions and technics are difficould. the valves it would take.
electrical controle is the common used method but also the most unstable.
we were constructing a mecenical presure vlave system, alle linked.

Yeah I have had a look at them and how the group B's used to twin charge etc.
It seems pretty straight forward, supercharger fitted, feeding a big TD05 turbo, pressure sensor valve in the intercooler piping which would read a certain pressure meaning the turbo was spooling so to send a signal to cut the charger, a Y shape pipe coming from the turbos inlet one side to the charger and one to a sealed valve, when the charger gets shut down the valve would have to electronically open to allow the turbo to suck the amount of air it needs....

its not a project mate, its a nissan production car, google nissan march superturbo, there is a lot of info, even wiki is orite

i dont think the march runs like that, its not in series, i believe its a 3-way v/v, and has a differential bypass pressure valve, and once the pressure from the turbo is higher than that off the pressure from the charger, then the v/v opens, and allows the pressure from the turbo to then enter the inlet.

Yeah thats correct mate, I want in series, nice winter project this is going to be!

my uncle had the twincharge corolla m8
if u use google type in 4agze turbo or along them lines
it should set u off with diagrams and images of how to do it
(4agze) but u can adapt it
i have thouht about it but it only really good for fast road
as the car will develop alot more torque....
u can possibly remove the power steering and fit a a super charger
there
i the calder racing develpoments twin charged a integra type r
just some random info for u m8

My experience has made me pretty much debunk any such effort. Its been tried here in Jamaica and it failed miserably, for the following reasons as anyone with twincharging experience will quickly point out...
1: Twincharger setups DON'T usually make more power than a single turbocharger. This is because the maximum airflow for hp is dependent upon the turbocharger. For example we tested our car, accidentally, against the twincharged EP82, it made 190whp while we made 210whp on 10psi. Both cars were 5E.
Therefore we kick to the usual reason for twincharging, response...
2: Any Starlet expert will tell you that the E-series motor has no problem with low-end torque or in general, boost response. Its actually the opposite in respect to the normal DOHC motors. The slave cam system is designed to boost torque and bottom end power. Whatever gains you believe you'll get with the supercharger will be negated by stress on engine, driveline and traction.
Bottomline, if you have to run a supercharger to help with boost response you're using a turbo WAY too big for the 5E anyway.

A lad pointed this out at the last drag race we had cause a guy from suriname made an attempt with this, nobody paid attention to the bloke cause he's usually known as a talkative guy so no one took him serious...
