thats why i am 12.5:1

Its not all about port flow to spool a turbo, its more about volume, displacement, compression, and fuel. Not really how well the port flows.
Im debating on bumping the compression up to maybe 10:1 but im not sure. E85 and e98 also have a much higher energy displacement which helps. But not all are running Ethenol.
A ve head flows pretty good and the couple cars in az that used this turbo were 1.9L 11.5:1 cars with semi ported heads that probably barely if that flow the same as the VE head. We will see, Im probably just gonna stick with 9:1 as I dont think i will have an issues plus im using the smaller 1.10 housing.
All I need is to make full boost by 7k and that will give me what I want. Because I dont mind reving out to 10k, VE's will take it all day long when built right.
