View Full Version : Twin Charge = Twin Cooler?
Twin Charged engines, i take it they have two intercoolers much the same as a TT 300ZX?
I guess it depends how the plumbing is setup... IE if they are in series then I think you can run one cooler. But if they are in parallel then you need one per charger
Thanks Stu :D
I just though being as at some point on a Twin Charge engine, the Turbo and the Supercharger will invetibly be running different boost pressures under load, so I'd imagine in theory they would need a cooler each?
ahhhh with a compound charged engine (turbo and supercharger), there is a valve (read that as throttle body) which turns off the flow of air from the charger not being used (ie S/C low down, Turbo high up) so you only need one cooler
^ just what i wanted to hear :D
I dont suppose you'd happen to know the "proper" name of said valve Stu?
something like a K gate is in the back of my mind.... might not be right but I know Ive heard it before lol
or google the S4 Lancia and see if its got any more info
random question but related to twin charge, was there ever a proto type Vectra GSTi, that had supercharger+turbocharger?

im guessing,
by "in series" you mean, like say on a v6, a turbo on front and rear manifold's..
and "in parallel" say like a big and small one's same manfiold?
:confused:
other way round ste.
although does depend how you feed the air into the engine.
oh yea, my mistake :lol:
i did mean it the other way...
as in series, runing inline, and parallel - side by side
