I'm building a TII motor right now but it came with an S5 NA rotating assembly. My question is would if be good with just higher octane fuel and watercmeth injection ? I can't get E85 around where I'm at, nearest pump is 3 hours away. What boost would I be limited too roughly/estimated?

Thank you

 

@rotorhead_izzy has a boosted 6 port S5. Take a look at his threads

thanks I'll take a look🤙🤙

 

I run up to 16 psi on my s5 n/a rotors on pump 93.
