Has anyone used either supercharger if so whick 1 is better and whats peoples results on them installed onto EB-AU any good at all

I would also like to know if anyone has had any success/issues with fitting one to an AU.

Also power figures they got and if internals have to be strengthened or changed.

cheers guys.

I had a powerdyne on an EF V8. Was awesome.

Only 170rwkw but enough torque to destroy bitumen...

Kit went on over a weekend. NO internal mods whatsoever... the engine was rock stock, even std headers.

Fitting a vortech is VERY similar (read: easy) but you need a return oil line tapped to the sump, which some people may not be comfortable doing in their backyard.

Vortechs have a lot more headroom... you can gear the pulley down, get more RPM and more boost... powerdyne cant really be pushed beyond kit setup.
