Taking a step back, I think you are more culpable in a crash having fitted a supercharger without certification (even if it does come with well-known stickers and a warranty) as you are better brakes and suspension.
Let’s face it, if Walkinshaw and Tekno and Harrop etc., are performing major mods without proper certification across multiple systems, I think the issue raised here is either a major scandal pertaining to duty of disclosure regarding roadworthiness and explaining customer’s legal compliance else... a storm in a teacup.
If the former then the multi million dollar parasites should chime in, eh?
