Some more amateur questions!
 

Sorry about this guys, find it hard getting info on my 1990 S5 aus delivered turbo model. xD Just a few questions! SCR inlet manifold, is that good? I have 4 injectors right, 2 per rotor? What size are they and what is the us in having 2x850cc injectors, wouldn't i need four? And on a fairly stock car(only have turbo-back exhaust), would those injectors be better or worse for my performance, same for the manifold? And finally what's a XF throttle body, and is it good?

All help appreciated!

I don't know what an SCR intake manifold is. Pics?

There are 4 injectors, two per rotor. One primary, one secondary.

The stock injectors are 550CC (covered in the FAQ).

Often only the secondary injectors are upgraded because extra fuel is only needed above 3800 RPM (when the secondaries come online).

Don't know what an XF throttle body is. Pictures?

These are all the pics i could get.

That fuel injector setup scares the crap out of me but that looks line a fine intake.

However that is way too much turbo for stock primaries and 850CC secondaries. You'll want to move the 850CC injectors to the primary position and go with 1600CC units on the secondary.

And you'll need a standalone EFI system control this, if the car is not already fitted with one.

The person who made it really should have consulted an engineer prior to designing it, and I am amazed that he is trying to sell it as a product. Stay well clear of this guy!

Thanks for the help guys. No that ain't my turbo(wishes), that's just the pics of the one i was thinking of buying(manifold, not turbo).

Cheers guys.
