Don't get stuck with a KO3 replacement that is less power then your OEM model 
 Don't get fooled by the Blades - check our blade count out - true EO5 spooling power 
FOR example , if you have a 2000 + Audi TT coupe, fwd 180 HP with ATC Engine -you will need to get the larger INLET pipe. Please contact us for further help and details.

There are 2 posted sets of graphs:
 1 shows this turbo at 266whp
 The second set of graphs show it against some known competitors after a retune. 
 In the last picture shown you will see e dyno.graphs. These are posted on my facebook pages as well along with a full review from a customer from Columbia. This dyno shows stock vs frankenturbo f21 vs my billet k04-001. The first graph also shows that my turbo has no lag just like the stock k03 and does not lag like the frank unit. 
This is real numbers done by a customer at 8600ft above sea level on 89 octane gas...the only available gas in his country.
At sea level and 91 octane we expect a 25% increase just based on atmospheric pressures and fuel. This potentially means 320+whp!!!!
