afternoon all, im after some information

i know some of you have twin charged your engines (turbo and supercharged)

i know of a manifold and turbo i can fit but how do you 'plumb' it all in so to speak?

do you have a sort of Y piece with one intake used for the supercharger and then one intake coming from the turbo and use a one way valve?

also when the turbo kicks in does it force the supercharger to spin up more?

not show how it works, just after some information really, it has been annoying me for a week or so now so thought i better ask the engine gods

thanks

Joe

read that and it will help out a little bit

 

thanks for that

by the looks of it only uses one intake pipe so it must suck air from the turbo until that spins up and blows the air into the charger. is this correct?

also the supercharger bypass valve - does this dump the air into atmosphere or inlet manifold?

thanks

Joe

 

the intake is through the turbo. once it cycles through the intercooler it goes to the supercharger just like a normal turbo setup would send air to the intake manifold.

Not sure about the bypass valve.

It's an awesome setup, but just a little too much out of my price range

 

yeah so the supercharger must suck air through the turbo until the turbo kicks in and then it blows air into the charger

i need a new exhaust system so may get a custom exhaust made so i can fit the turbo

 

~thinking to self~ umm twin charge a SS/TC would be sexy!

 

im thinking about twin charging this:

 

the turbo is your intake pretty much man. there isn't any kicking in of the turbo. however boost is a different story. you're cycling air through your system to the supercharger in just normal driving and boosting. the way they have it setup is you boost from the supercharge in low rpm's until the turbo spools up and creates its boost then you will not be boosting from the supercharger anymore. at that point its only purpose is really just an intake manifold.

good luck with that project

 

so does that mean the turbo will be making the supercharger spin round quicker? or just goes down the bypass valve into the inlet manifold?

thanks and am just gathering information and being noisy really lol

 

this spinning around quicker is when its making boost. so once the computer says to switch from s/c to turbo it wont gain any more boost. should remain at a constant state. and like i said earlier im not sure about the bypass valve in that setup. all i know is once the turbo spools, the s/c will stop boosting and just maintain air flow into the motor. What you should do man is send zzp a pm or email for your more specific questions.

 

i know thats when it is boosting more, just trying to figure out how the air from the turbo gets passed the supercharger...

the computer cannot tell the supercharger to stop as it is belt driven?!

i might have to email them

thanks again for all your help and if anyone can answer these questions tonight i will be very pleased

 

i may not be understanding your question right, but both chargers work as a team. try looking at the pictures from the link i gave you..that might help

 

this is where i got confused and thought you meant the computer turns the supercharger off! but obviously you cant as its belt driven!

it doesnt really explain in that link how the air gets into the intake manifold... whether it forces the supercharger to boost more by blow air into it or if it goes in through the bypass valve.. not sure if the bypass valve just dumps the air to atmosphere or if it dumps the air into the intake manifold if you know what i mean?!

the turbo doesnt even have anything to do with the computer does it?!

 

Well i have done some research cause i plan on getting the twin charged... but from what i found out is the supercharger boosts until a certain psi(depending on what you have it at) and once the turbo spools up then the supercharger acts as a second intake and doesnt spin any faster...

 

if it doesnt spin any faster then how does more air get in?

 

bypass valve doesnt dump into the atmosphere. it bypasses the supercharger and goes directly into the intake manifold. ZZP just tested their twincharge setup and found the most effecient way of introducing lots of air into the manifold was to leave the bypass open.

interesting.... hmm is this an electronic switch or pressurised switch?
