Factory SC Boost

[littlejon]

Hey,

Just bought a VT Calais with Supercharged V6 and was wondering what the standard boost is off the showroom floor? Not really interested in tweaking but just curious.

Thanks

As slundy said...6 psi.

I have seen some quote only 5 but mine was 6 when stock.

 

[VS CALAIS]

Yeah depending on the car itself anything from 5 - 6 psi , of memory i think holden actually quoted 5.5psi , could be wrong though

As lame as it is, I think the XU6 has 8psi of boost..

You wouldn't bother with the car though, unless you were lame..

 

[SUPERV6]

No the XU6 was only 6 also. All L67's were fitted with the 3.8" pulley.
