I've looked everywhere for this... I got some formulas and worked out what I thought was the the correct way to do it and I am way off. I'm wondering if anyone knows what the AR size is for a F22B2 that I am going to turbo. From what I've read it depends on displacement and many other things.

Whats an AR? You mean compression ratio?

 

No i think hes talking about the AR of a turbo. its volumetric efficiency. youre looking for a t3/t4 hybrid turbo. will spool quick for the engine. I believe you shouldnt go any higher than .50 Ar if youre running on stock internals and running low boost. you wont need it. i believe so anyway.

 

that is correct. up to 7psi(more like 8-9psi but 7 is safer)
