types of turbos setups.?

[SOBIL]

Pardon my ignorance when it comes to turbocharged shit boxes, as I have only worked on newer cars.
Could sombody please explain suck through turbo setups, aplications, benifits, limitations. Just curious.
Gene I'm expecting your response????

a draw through setup is where the throttle body or carby is positioned before the turbo. limitations to this setup are that you cannot run an intercooler which means higher temperature air/fuel mixtures enter the engine, with increased possibility of detonation, sometimes you can use water/ methonol injection to combat this.

blow through is where the carby is after the turbo, this means you can run an intercooler, but you have to invest in a seal kit for the carby to withstand the boost pressure. otherwise u will blow all the seals apart and leak feul everywhere.

generally both setups are less effective and run rougher than the fuel injected later model cars you work on.
there will be flat spots all through the rev range.
hope that helps you. SHEEL

-let me say one thing, "Turbocharged" and "Shit boxes" don't ever go in the one sentence, ever, got that!

plumb back anything. why? cos the atmo (normal) BOV sounds gay and is "fully wank factor"
