Some of you guys don't understand these things very well. Just simply adding a bigger compressr wheel isn't going to give you a substantial power increase unless you are exceeding the flow of the outgoing wheel. You will see a gain from the larger hotside. It is unlikely that you will see a significant gain on pump gas unless you have all of the supporting mods to maximize airflow into the engine. The stock wheel has been shown to support 400+whp so it is unlikely you will see much of a gain at power levels lower than that when compared to a turbo with the larger hotside.

 

i cant believe people are buying this turbo based on a few customers comments and a picture of the little wheel sitting on $100 bills
