Holy crap - Former_boosted_IS on the US forum has finally released the full review of his 700bhp Vishnu Single Turbo conversion.
645 rear wheel horse power (i.e. over 700bhp crank) on an otherwise standard block and internals / transmisson / manual gearbox.
Over 500lbft (700nm) torque all the way to the red line!
Shows the strength of the factory components.
Watch video, great just after 1 min
Read the whole review
Awesome - could me a mod for the future!
