TurboGSR96
Sippin Corn Whiskey
For comparison though I have a GT3037 Pro S with extrude honed housings on a 2.0 and it will hit 20psi at 4500
How is that a comparison? different engine different turbo, mine is off the shelf stock and the one you mention has been ported.........
If I wanted to make 25psi at 4500 I could, just brake boost..... works lovely. BTW you might make 20psi by 4500, but can you rev past 10k safely?
