Now, this was a great day! We met Chris to see what his Supercharged Astra Van was all about. Check his instagram out at / charged_opc_van
'This van is a 1999 S reg which is pretty much the first batch of mk4 vans to be built. I love the noise of the supercharger, its loud and always the first thing people comment on.
I also love the overall set up, its not perfect yet but close.
Its not a high powered build. I grew up with by dad always telling me that power isn’t
everything, a well set up car is far more menacing than being able to go fast in a straight line
and I think my van proves that.
I also love that I still haven’t seen or heard of another supercharged astra van so I’m led to
believe it’s the only one to exist'.
Chris would like to thank...
'Carl Evans for showing me what a 2.2 chain snapper can do.
Courtney Sport for mapping it.
ARC Specialists for painting it.
Jeff Reiland for supplying the supercharger and posting it from the USA.
And most of all my wife Julia Smith for putting up with be disappearing for days on end to
build this van'.
