Here's the question: Which would be best in a BP single turo set up? I know that with the zenki rotors you can run higher boost due to the lower compression, but is it really worth it? Or will the FD rotors make the same hp at lower boost? There are advantages to to both, just wonder if anyone has experance with this. Starting to build the next eng, so when I blow this one up I will be ready.

the higher compression rotors will help with spool up, this might be a motor for some s4 na rotors (9.4:1)? on the other hand the 8.5's give you more fudge room on the tuning

Thanks for the response j9fd3s, I can't believe none of the BIG DOGS gave any of there ideas/options. What's the deal?
