I had that turbo and it kicked *** for 7 psi. It looses boost top end though. But if you want to pass someone just step on the gas and go. Pretty much no lag when cruising. Hits full boost at 2,500. It will roast your tires.

 

I loved my rhb5 on a stock y7. I ran that lil ****** at 1 bar everyday for 3 months until the infamous y series spun bearing peeked it's ugly head in. I liked it cause it didn't even feel like it would spool and more like a powerful NA setup.
