There is a 40 page thread about Hyper gear turbos in the Forced Induction section.
All results for each turbo, various users etc.
And a good 20 results in the dyno sticky as well
Have a look in those threads mate, or simply search FI with "hypergear", you'll get more information than you'll get in this thread.
Or you could just PM them, given they are a SAU trader and have an account here.
